How to install a soft start on a miter saw

Power

For a household appliance, a power of 1200-1300W is suitable, for professional units. 2000W. Pay attention to the speed of rotation of the saw blade. The model may have a lower speed, but due to the number of revolutions, its productivity increases. Optimal performance. 3200-5500 rpm.

Cutting precision

The cleanliness of the cut depends on the material, sharpening, geometry of the teeth of the saw wheel. The presence of a clamp for the workpiece helps to achieve an accurate cut. An important role is played by the adjustment of mechanisms and parts. Before buying, it is worth checking that there are no backlashes and distortions in the design.

Kerf width

This indicator determines what workpieces the operator can work with. The cutting width is related to the disc diameter. In some models, a broaching system is provided. The width of the cut should be chosen based on the tasks for which the user is oriented.

Cut slope

Adjusting the position of the saw blade is an important point when choosing a device. In almost all models, the disc is rotated to the right and left. This allows the operator to make different cuts. Average tilt of the head to the working table. 45-55 degrees.

Tool selection criteria

Cutting height

Shows how deep the cut will go. For household saws, the optimal value is 5.5. 8 cm, for professional. from 10 cm and above.

Tasks

The choice between the classes of the device depends on the scope of its application. For occasional woodwork, small repair work in the household, household appliances are suitable. For complex tasks, for example, for cutting blanks in a furniture factory. professional.

Reviews of Metabo KGS 254 M

Advantages:
The assembly is of high quality, the laser and the illumination of the desktop are networked, the bearings are of high quality, the disc brake is good, I like the tool. 3 year warranty.

Advantages:
Excellent machine. Powerful. there is a laser and illumination, a clamp is included.
the degrees at the school are clearly set. at corners 45 and 0, the notch will not miss a millimeter.

Disadvantages:
I see one disadvantage is the lack of a soft start, with a soft start, they cost other money.
You can put a smooth start yourself 🙂

Comment:
At the dacha, we are building a bathhouse ourselves, and when the interior decoration began, we decided with my father to take this particular trim. Sawed platbands. skirting boards on the floor and on the ceiling, all corners converge clearly. For the sake of interest, from a piece of platband they assembled a square of all 4 saw cuts exactly 45%. We connected a vacuum cleaner there is almost no debris in the workplace; without a vacuum cleaner, little gets into the bag 50/50. The standard disk is quite good, I do not plan to change it yet.

Advantages:
Works in small carpentry. Ok, but so far new.

Disadvantages:
It has not yet been identified, but according to primary sensations, it is possible very soon.

Comment:
Before that, I had been using the same model for almost three years, but with a German assembly. This assembly is Chinese and the difference was felt as soon as it was taken out of the box. Some metal parts were replaced with plastic, the bed and the saw blade broach became 2 cm less. The weight has also decreased. Feels more flimsy. Then time will tell.

Advantages:
Sharp fast cuts even with a native disc

Disadvantages:
First I made goats for the table. I liked the convenience of work. Started cutting 45 for platbands. This is where the problems started: the angle does not converge by 90. Then I found out that there is a deviation of 1 mm for 30 cm of the cut of the right angle. I gave it a week ago to the Metabo service center on Birch Alley. returned today with the same deviations. The master told me: this is not a measuring instrument, it does not have an accuracy class, deviations are possible. Push the handle more to the left. the cut will be more accurate. In general, I am shocked by both the tool and the service.
Add-on from 01/24/2019: I applied again to the same service, this time with an official claim. After adjustment, we looked at the cutting angles together. both at 90 and 45 degrees. gives a deviation of up to 1 mm by 30 cm. It is critical for me to cut door frames, so I asked to write a Non-Repairable Act, with which I left. Since production takes place in China, such cases are possible. someone is less fortunate.

Comment:
This tool is not recommended for purchase if you buy. then check carefully.

Advantages:
Lived up to my expectations. Easy to operate, safe, excellent cutting quality.

Disadvantages:
I haven’t identified any shortcomings yet.

Comment:
The impressions of the product are very good: outwardly elegant; burr-free platform, perfectly processed; the laser line is clearly visible. Thank you!

Advantages:
Power, precision, laser, light.

Disadvantages:
Light and laser buttons without protection

Comment:
The saw performs all that was required from trimming. Saws quickly, at exactly the right angle. And all this is out of the box, without dancing with a tambourine and adjustments. The problems with the laser and illumination, voiced here, have not yet touched me. But they grow from the “quality” of the power buttons. They become clogged with dust, because there is no protection. Therefore, either prevention with a vacuum cleaner (frequent, you can even without removing). Or replacement with similar ones with a silicone cap (there is a video on YouTube).

Advantages:
Even those who have never sawed can do it. Rich functionality. Best for the price

Advantages:
This is the third trimming. and I can say. that I had nothing better. and the laser is there. where the dust does not fly and the sparks do not fly when braking. backlight how i used to work? I recommend both price and quality

Disadvantages:
All flimsy. All this Chinese miracle consists of small backlashes. The laser is not precisely tuned and, in principle, useless, since after the first saw cut it becomes covered with dust. than one value of the angles will not coincide, both horizontally and vertically. No soft start, it’s goodbye bearings that cost horse money. Consumables and spare parts are unrealistic to find.

Comment:
I didn’t think that having bought such a saw for such horse money, I would get a frank China of an average hand. In general, we forget about even cuts and get used to the constant feeling of cheap Chinese. Our brands for 8-9 tr do much better, at least they do not slap.

Advantages:
Laser, price, easy to carry and a bunch of bells and whistles.

Disadvantages:
heavy, no soft start, but already used to without it.

Outer and rim diameter of the disc

The rim of the blade affects whether it can be fitted to the saw at all. The most popular value is 30 mm. As a rule, you will come across saws designed to work with just such a consumable.

There is much more variety in the outer diameter of the discs. It can be specified in inches or millimeters. The most popular is 255 mm. The larger the diameter of the consumable, the larger the workpiece you can cut. To work with a large blade, the saw will need more power. In any case, you will not be able to install a disc with a diameter larger than the allowable one. it will not snap into place. This design feature of miter saws ensures safety during work.

It is also not recommended to install discs of too small diameter. When you turn on the saw, the engine will experience a minimum of resistance and will start to produce too many revolutions. this will harm the saw.

Maximum workpiece width

The maximum workpiece width depends on the disc diameter and the availability of the broaching function. The larger the diameter, the larger the width of the workpiece can be cut. The broaching function assumes the ability to move the power unit along the workpiece using rods and guides. For wide workpieces, choose a feed saw.

Asynchronous motor

Among all types of motors, asynchronous is considered the most economical. It is reliable and makes little noise. Asynchronous motors are reliable, as they have a minimum number of rubbing elements. This allows them to heat up a little and not wear out for a long time. the only part that is subject to wear is the bearings.

Among the disadvantages is the high ratio of mass to power. An asynchronous motor with a power of about 2 kW will weigh about 20 kg. This imposes some restrictions on its use, since it is not very convenient to use an overly heavy instrument. In addition, when operating on electricity with an industrial frequency, the engine will not be able to develop a rotor speed higher than 2850 rpm.

Additional features of the miter saw

Every modern saw is equipped with additional features designed to increase comfort when working with a miter saw and provide the necessary level of safety.

Protective cover

The protective cover serves to protect the operator during work. Even when the saw is on, a special guard covers the blade. As it is immersed in the workpiece, the casing moves back, revealing the disc.

Tooth shape

There are teeth with different shapes:

  • Trapezoidal. Works well with wood, chipboard, plastic parts and non-ferrous metals.
  • Concave. Used to saw multi-layer materials such as laminate.
  • Replaceable (teeth beveled alternately in both directions). Well suited for working with plywood and MDF.

Cutting depth limitation

This feature aids in grooving or trimming jobs by limiting the depth to which the disc can plunge.

Miter saw power

The power of miter saws is most often in the range of 800-2500 watts. Saws with a power of approximately 1600-1800 W are considered universal, since they are suitable for a wide range of tasks, performing both domestic and professional tasks. They are often bought for home workshops or small businesses.

Power consumption is an important parameter. If you choose the right saw, it will be possible to achieve the optimal ratio of power and the processed material, to make the work more efficient. The higher the power, the larger the diameter of the blade can be mounted on the saw. The reverse side of the coin is an increase in the weight of the saw and its dimensions.

How to choose a miter saw

The miter saw (or as it is also called. “Trimming”) is considered a fairly common tool. Saw data models are found in the catalogs of many manufacturers. The tool is popular among both professionals and amateurs. However, each user makes his own, strictly individual requirements for the car. For one miter saw. this is the main source of income, for another only a hobby or a necessity caused by maintenance or private construction.

Special purpose

What are miter saws actively used for? They are used for sawing wood blanks at a right, oblique given angle and at an angle. They are capable of extracting material from a workpiece. The scope of use of saws is very wide: they are used for finishing, carpentry and assembly work, they are extremely useful in the manufacture of furniture. Traditional use of miter saws. execution of work on the production of window frames, door frames and flooring.

How not to make the wrong choice?

First of all, you need to understand as clearly as possible what a miter saw is for. In the event that for simple and rare works without intensive loads, it may not make sense to purchase an expensive professional class car, it is quite possible to get by with a budget option that has a typical set of functions. However, in the event that more difficult and responsible work is ahead, when the accuracy, accuracy and endurance of the instrument are important, then it is worth studying the proposed highly professional models, investigating their capabilities.

Miter saw design

The miter saw is quite simple: a motor with a gearbox. so-called working unit, saw blade, handle with start button and base. Motors are used both collector and asynchronous. The first has a high torque, but requires attention and regular service. replacement of collector brushes. An asynchronous motor has no brushes, it functions with less noise and lasts longer. Traditionally, the motor is located to the right of the saw blade. Although on some machines it is shifted back for a much better view and ease of work when performing an inclined cut. The motor drives the saw blade through a gearbox.

There are two types of transmission: belt and gear, each with its own advantages and disadvantages. Toothed gear eliminates slippage under heavy loads. The belt is less noisy, dampens the vibration of the disc, which has a positive effect on the quality of work and the resource of the motor. In the process of choosing a facing, it is necessary to pay attention to the device of the tilt mechanism of the working unit: whether it is an integral part of the movable console or is it rigidly fixed. The working part of the facing is based on a bed with a circular section that can rotate and a parallel stop consisting of 2 parts. Quite often, the beds are made of aluminum or magnesium alloy, which provides strength and mobility, the weight of the tool in this case becomes significantly lower.

Saw adjustments

To make a bevel cut, you need to rotate the table. Rotation angle range from 45 to 60 degrees in both directions. Traditionally, adjusting mechanisms are provided with latches for quickly setting fixed angles of 0, 15, 22.5, 30 and 45 degrees. Other angles are set on a special scale. The saw blade is also capable of tilting occasionally. A significant function of almost any miter saw is the ability to limit the depth of cut. This is necessary when trimming profiles or cutting grooves.

Electronics

Usually miter saws do not have a wide range of electronic adjustments. Few models are equipped with an electronic speed control. This is due to the fact that changing the speed is not a particularly important need. The presence of such an adjustment allows you to reduce the speed and control the process much better during cutting, adjust the miter saw for work with a certain material. Even less common is the function of maintaining continuous speed under load. Under strong pressure, as a rule, the engine speed drops significantly. Electronics is able to make an amendment to the speed, on which the quality of the cut depends (at high speed it turns out to be cleaner and tidier), and the time it takes to complete the task. Some trim models are equipped with a laser that indicates the line of the planned cut.

Dust extraction

Just about any miter saw produces a lot of dust, sawdust and debris. Miter saws have several options for dealing with debris. It can be collected in a linen bag. Or use a vacuum cleaner, the connection pipe for which is available in almost all modern models of the tool. Traditionally it is located at the back of the saw.

Choosing the right saw blade

The saw blade you choose depends on what material the saw can handle. Main material for trimming. wood (hard and soft woods), plywood, veneer, etc. However, plastic and laminate, soft non-ferrous metals saw through the teeth. The main parameters of the saw blade. its outer and bore diameters. The landing is traditionally 30 mm, the outer dimensions can be very diverse, but discs with the outer dimensions of 210, 250 and 305 mm are especially common. It is always necessary to remember that the drive is designed for the use of a certain disc, which is why working with a larger diameter disc can be simply harmful for it.

The parameters of the protective cover are also calculated for a specific disc: a disc of a larger diameter simply will not fit. Discs differ in geometry and sharpening of teeth, material of manufacture. All this has a significant impact on the quality of work. The teeth of one configuration provide high speed during cross-cut, another configuration will perform well for longitudinal cuts, and the third will provide a clean and neat cut. Another special feature: some saw blades have fine cuts or wavy mowing lines. These patterns are laser-printed on the disc, they are functionally substantiated. to compensate for thermal deformation and to reduce operating noise.

Safety regulations

The miter saw is a cutting power tool. When working with it, you need to take care of your eyes, do not forget about protective glasses during operation. The most obvious defense. casing. With its movable part, it completely covers the saw blade in non-working position. During operation, the casing retracts and exposes the disc in two ways: either the user, by pressing the lever on the handle, removes it independently, or the disc opens itself when the console is lowered. For greater safety, the system is equipped with electrodynamic brakes that smoothly and quickly stop the motor when the power is turned off. The safety system of miter saws includes: soft start, blocking of switching on when changing a blade, automatic shutdown when the blade gets stuck, protection against breakdown of electricity to the body, a comfortable and quick system of fixing the workpiece.

One of the layout options for a homemade launch unit

As an initial version, the author of the following video chose an assembly known on the Internet with an LM358 microcircuit. Since the assembled starting block did not fit inside the angle grinder, the author “packed” only a triac with a radiator inside, due to the good cooling conditions from the fan wheel, the angle grinder. The rest of the block, together with the microcircuit, was fixed on the case by an angle grinder.

Starters for Bulgarians 1000 W

Starters for these Bulgarians are made on triacs with an overload of 20 A. The standard circuit of the device includes a triode, a stabilizer and three transistors. The rectifier unit is most often installed on a wired basis. Capacitors can be used with or without a filter. The minimum frequency for the conventional model is 30 Hz. At 40 ohms, the starters are capable of supporting high overloads. However, problems can arise at low speed Bulgarians.

Features and service life

In hand-held power tools, such as: angle grinder (angle grinder), circular saw, screwdriver, drill. use collector motors with sequential excitation.
They can operate on direct and alternating current.

For their power supply, in most cases, a normal 230 V 50 Hz power grid is used. Previously, a 380 V network was used for a professional tool. Now, with the growth of consumer power in single-phase networks (offices and the residential sector), professional 220 V power tools have also appeared.

Collector motors have high torque and starting torques, are compact, easily manufactured for increased voltage. The torque is decisive here. With a low weight of the machine, it is just suitable for hand-held power tools. But such electric motors have drawbacks and weaknesses. One of these weak points is the brush assembly.

Compressed graphite brushes with fillers rub against the copper plates of the collector and are subject to mechanical wear and electrical erosion. This increases sparking and increases the fire and explosion hazard of the power tool. The penetration of mineral dust into the interior accelerates wear. Although the fans are designed to blow air out, dust and cement can easily get inside. During standstill, if the tool is unsuccessfully laid down, dust easily gets inside. In practice, this is a constant phenomenon.

Compressed graphite motor brushes

Another drawback of the power tool is the frequent breakdown of the gearbox. This is precisely because of the large starting torque. Dignity turns into a disadvantage. With a breakdown of the gearbox, you have to change the tool, they usually cannot be repaired. Unfortunately, the industry, in an effort to reduce the cost of production, does this at the expense of quality. If you want to use a good power tool, pay a lot of money.

The last drawback can be effectively dealt with by a soft start. Many manufacturers do this, but do not always pay enough attention to it. Not all instruments have good speed controllers.

Selection Tips

How to choose the right angle grinder? To do this, it is worth using several basic criteria.

To choose the right tool, it is worth deciding on the specific type of work to be performed with this tool. angle grinder can be of different types: mains, with batteries, gasoline and pneumatic.

Network models are perhaps the most common. Such an angle grinder works from a home network, that is, from a simple outlet. Such models of the tool have high power, compactness and high rotational speed of the cutting discs.

But the limitation in working with such an angle grinder is due to the dependence on the mains. For example, when working on the street, there is not always a power outlet nearby and you have to use various extension cords.

install, soft, start, miter

Battery devices are deprived of this disadvantage. They have a special mount for power supplies that are charged from the mains. After charging, you can work with such a tool without any wires. Typically, such an angle grinder has a compact size and small diameters of cutting discs. As a rule, such models are more expensive than standard tools. Also, the period of their work is limited by the capacity of the power supply.

Gasoline angle grinders are not common. Such devices are large in size, because they need a fuel tank, as well as an internal combustion engine. Among the advantages, it is worth highlighting the high power of these models, a wide range of disk choices and autonomy. The negative aspects include their weight and volume, high noise level and, of course, additional fuel costs for the operation of the device.

Pneumatic models of an angle grinder are often used for industrial purposes and very rarely for household work. This is an unusual angle grinder that runs on compressed air and needs a special compressor. For such models, the problem of overheating is completely eliminated, and the period of operation can be limited only by the human factor. Also, such models are the lightest and quietest.

For simple work on the processing and grinding of surfaces, light models of grinders with a small diameter of the cutting wheel are suitable. For work on cutting durable materials, it is worth choosing more powerful and, accordingly, bulky equipment with a large diameter of discs. The diameters of the discs can be from 125 (minimum size) to 230 (maximum size) mm. that is, the range of sizes is quite wide. The universal cutting disc diameter is 180 mm. Such a circle can both process surfaces and cut material.

When choosing a disc, it is worth conducting a careful visual inspection. Even minor damage and chips can lead to extremely sad consequences. By the way, almost 90% of accidents when working with an angle grinder are caused by a defect on the cutting discs.

Convenience of work is also an important selection criterion. The angle grinder should be equipped with comfortable handles, should not slip out of the palm and be heavy. Many angle grinders have an electronic relay to protect against power surges and overloads. This is a useful feature, so it is worth choosing a tool with such a fuse.

It is recommended to select models with a soft start function. This will help the tool last much longer, and it is much more convenient and safer to use an angle grinder with this function.

How to connect, installation

For angle grinder users who do not have wiring skills, a separately sold soft starter is available. It will only be necessary to install it correctly. There are two options for placing the starting device. inside the case of an angle grinder and, if impossible, outside.

In the next video, the author placed one of the purchased blocks with the help of a slight refinement of the case, an angle grinder placed inside it. The two wires of the starting block are connected according to the following scheme: one wire to the switch contact, the other to the stator winding of the electric drive.

In another video, the author also managed to fit the purchased block inside the angle grinder. However, he chose a different connection scheme. to break the network. In this case, it is not important to consider where to connect “zero”, and where “phase”.

Technology of works on the manufacture of the launch unit

How to check

At home, before assembling an angle grinder with a soft starter, it is a good idea to check it for an open circuit. The following video tests a device with three pins. Usually there is a wiring diagram on the body of the starter. There are two mains wires, one goes to the electric drive. If you assemble a circuit with an indicator lamp, turning on the starting device, then it is possible to determine a break in it by lighting up / not lighting up the indicator lamp.

Smooth start for a miter saw, what is it and how to do it yourself

Expensive tools are not always relevant for home use. But cheaper options are not equipped with special electronic current control boards, so a soft start is not provided, which often causes premature failure of the device. A small do-it-yourself modernization allows you to save electric saws (circular and crosscutting), as well as drills, grinders from overloads, and such a scheme is not so difficult for self-repetition.

Why do you need a lightweight start-up power tool

The soft start circuit is a small-sized assembly of only 5-6 electronic components based on a powerful semiconductor controlled by a microcircuit. The dimensions of such a board allow it to be placed directly in the handle of the power tool, but modernization is not always promising due to the need to maintain the manufacturer’s warranty, as well as the possibility of using such a device for various tools. You can make the launch scheme yourself using several options for drawings from the Internet, but the easiest way is to use ready-made blocks offered for sale for trimming or drilling. They have many modifications, which requires an understanding of the principle of soft start and the benefits obtained.

A slow start is necessary primarily for miter saws that are not equipped with an engine speed control unit. It is advisable to make a smooth start of the tool with your own hands for a number of reasons:

  • Starting a powerful electric motor leads to significant surges in the power grid (peak surges), which negatively affects both the tool and the wiring. Alternative sources of electricity, such as generators and inverters, are overloaded in such a situation and either turn off automatically or may fail. Triggering through a dedicated module significantly reduces the peak voltage surge, which eliminates the possibility of overloading the entire circuit.
  • Trimming without a soft start quickly fails due to the accelerated grinding of the brushes, as well as the occurrence of an electric arc between the contacts, which creates burnout of the armature lamellas and causes a short circuit of the rotor and stator windings. The engine sharply picks up speed, which, with significant saw diameters, leads to large inertial forces that affect the displacement of the tool not only in the hands, but even on stationary fasteners. Such an abrupt start can lead, at least, to cutting the material in an unplanned place, at the very least, to ripping out the trimming from the hands or fastening with the probability of an accident. Installing a small block eliminates such problems.
  • The slower acceleration of the rotor on the miter saw ensures not only its safe operation, but significantly extends its service life, since shock loads in the mechanical part of the tool disappear at the moment of starting. Gears in gears do not beat each other, and the torque is correctly distributed without destructive consequences, which significantly reduces the mechanical development of the unit.

Do-it-yourself safe start

To make the most smooth start of trimming, you can use one of the popular methods:

  • Assemble the electronic circuit yourself according to the drawings offered on the Internet. This method is more suitable for lovers of electrical work, since knowledge and skills are required for the selection of components and debugging of electronic assemblies. Parts are purchased strictly according to the required parameters (ratings), and their dimensions are important to minimize the mounted board. Do not forget that the unit will operate under high voltage, therefore, the quality of the soldering and the general installation must comply with the rules of electrical safety. For this reason, the method is not suitable for the average home craftsman.
  • Purchase a specialized soft start unit (BPP) and connect it to the power tool. To ensure a soft start for various household appliances with electric motors, it is recommended to place the purchased unit in an extension cord or carrier. But, it is worth considering that there are several options for factory modules for slower overclocking, and they are not interchangeable.

The described method is suitable only for collector motors, it does not work with asynchronous motors, they have a different principle of winding excitation and a completely different device is required to adjust the start. BPP is designed to connect only one consumer, simultaneous connection of several devices is unacceptable.

Modifications of PP blocks

Delay start electronic assemblies are available in several modifications and with different technical parameters. The current-carrying capacity can be from 10 to 50 A and is selected on the basis of consumer data, while the dimensions of the assemblies differ insignificantly. To modernize trimming with your own hands, it is recommended to use power blocks with a margin, this facilitates the operating mode of the general circuit and makes it possible to connect consumers of higher power. The most common PSUs are considered to be 16 A, suitable for electric motors up to 3 kW. this is the maximum power for household power tools.

BPP differ in structure and connection method:

  • Modification with three contacts (wires).

It cannot be connected according to the above principle, since it has a control conductor, the supply of voltage to which leads to the flow of power current between the other two contacts, which should lead to the start of the engine. Such modules are mounted inside a hand-held power tool (trimming) with a control wire connected to the start button. An attempt to connect outside a household appliance requires the installation of a separate button, and the trigger key on the tool must be locked in the on position, which is extremely inconvenient for use in facing hands. Other connection options do not give a soft start effect, and the power supply unit remains under constant voltage, unsafe and ineffective. Such a model of blocks can be used to adjust the rotor speed, and the control wire is connected through a variable resistance (resistor), which performs the function of a regulator.

  • Version with two wires (contacts).

It is connected to an open circuit, that is, to one of the wires that feed any collector motor. The effect of a slow acceleration occurs due to a short-term decrease in the starting voltage without reducing the passing current, which provides a soft but confident start. It is these blocks that can be mounted both in stationary and portable sockets, and the power button on the miter saw retains its functionality.

BPP with three contacts are suitable only for stationary power tools, for hand-held household appliances, blocks with only two wires for connection are used.

Mobile Lightweight Tool Launcher

The simplest option for organizing a smooth start for various hand-held power tools is to install the BPP into an extension cord outlet, because its quite voluminous body has enough space to accommodate even the most powerful unit. Modernization does not take much time and effort:

  • Carefully disassemble the extension cord case, providing access to suitable wires.
  • The PP unit is connected to the break of one of the wires, which can be done in one of the ways: directly to the break of the wire with the organization of reliable twisting and insulation or to the wire and the contact group.
  • Placing the BPP in the socket housing is recommended at the maximum possible distance from the contact group with adhesive reliable fixation, since there is always a possibility of heating the unit, which reduces the insulation protection and can lead to a short circuit during vibration.
  • The assembly of the case must ensure reliable laying and fixation of the wires without crossing.

All electrical installation work carried out must meet electrical safety requirements, so you should not engage in modernization with insufficient knowledge of electrical engineering.

    There is a top view in the second minute. You can see everything there. take a freeze frame and everything will become clear to you.

    DeWalt DW745 soft start module install

    Hello, it is not clear what the environment is connected to. Black wire, please tell me

    but how to choose a soft start block, for example, for a 1600w end saw!?

    This unit is suitable up to 2500, I have a saw for 1800 watts, so there is enough stock)))

    Vadim Plotnikov means fit?

    The warranty after installing the soft starter will fly?

    Sergey Zhuk I think yes. I don’t really hope for a guarantee. after a month

    two get out all the problems. then you just don’t need to rape her hard.

    It has been working for six months already. But it was not with me. I’ve been with me for a month. There are a couple of points. 1. When I put a workpiece 50 mm by 20 mm on the end of 20 mm. then a cut at 90 degrees of some kind of curve and there are semicircles at the places of the cut. When the workpiece lies on it, the cut is clean. It seems to hold 45 corners. 2. In a wide workpiece, when sawing at 45 degrees, a small arc appears, as if inside the workpiece. The disc is native

    change disc, buy something good. smt or freud, etc. but pay attention to the number of teeth and for which saw they are designed. do not throw out the old one, it will come in handy to cut wood. I have already sharpened it twice)))

    CMT stands like a trimming floor.

    Yes, but you will be using it for a long time, and this diameter will suit you even in a table saw.

    I was told, and there is a video, where they say that after installing the soft starter, you cannot use the laser and backlight.?

    Sergei beetle don’t listen to anyone. I’m fine. I inserted it into the chain between the motor and the start button. And those who say that you cannot use it mean that if such a unit is placed in front of the saw, then when the light or laser is started, the unit will start up full current and there will be no smooth start

    I forgot to write that in front of the saw. I have a drink under warranty. Then everything is correct. I’ll put it in front of the saw, I’ll shine a lamp.

    Sergey Zhuk this is your only way out for today.

    Repair of the illumination of the Metabo KGS 254 M miter saw
    Link? V = mS6ZcZokXW4

    Ah. be sure to screw this block into the saw body. Wouldn’t it be easier to equip an extension cord with this block.? And connect an electric tool through this extension cord. Do not?

    Alexander Sprutov no. You need a backlight and a laser, if you turn it on, the soft start will not work.

    My laser is shitty (weak), I started to change or cheto can be done

    Andrey Nikolaevich, I think it’s worth checking it and replacing it. As far as I know, they are not being repaired

    NiceTool, thanks, I’ll try to replace how to get it.
    For modernization, a separate SPS

    and the power drops under load?

    Vasily Andreev did not notice this, there are more than capacities)
