How to change trimmer line in a trimmer

The grass trimmer is the most common unit used for cutting grass and small shrubs. This machine is distinguished by its ease of maintenance, uncomplicated operation during work, and thanks to its low weight even women can cope with it. It’s not a secret that high-quality performance of works on grass mowing requires correct selection of cutting tools. As the latter, trimmers use special cutting attachments (discs, knives) or trimmer heads with a fishing line inside. Nozzles and fishing line for trimmer is an expendable tool, but if the blades can be sharpened, then when the line is consumed, it is required to replace it. In this article we will tell you in detail about how to correctly replace a line for a trimmer.

Grass mowing head is a cylindrical body, in which a spool (bobbin) is inserted with a fishing line (cord) tucked into it. This design can be mounted on both gasoline and electric trimmers. The heads differ in the way the cord is threaded and fed and come in 3 types.

  • Automatic. The filament is fed in after the user has reduced the engine speed ;The filament is fed in after the user has reduced the engine speed. Although automatic line feed is convenient if you perform a large amount of work, but such bobbins have one drawback. a large consumption of thread.
  • Semi-automatic. Using this type of head does not require the user to perform complex manipulations. The principle of their work is designed so that the cord is lengthened automatically while the machine operates at full speed. It is enough to slightly knock the grass trimmer head on the ground (this removes the cord lock), and the line for the trimmer thanks to the centrifugal force is pulled out of the bobbin, after which it is cut to the desired length by the knife located on the protective casing.
  • Manual. Extending the cord requires the machine to stop, after which the trimmer line is pulled by hand.

Based on the above, semi-automatic bobbins are the best option. Also keep in mind that the grass trimmer spools for grass can be single string (used only for trimming the grass) and double string, which are used for mowing tall grass and small, with thin stems of bushes.

Algorithm of installing a blade on the grass trimmer

Changing the blade on the trimmer is simple enough. The manufacturers include a wrench to remove the cutting head (bobbin with a fishing line) and a pin designed to lock the gearbox. To change the disc, you need to do the following steps:

  • Remove the hood that performs the protective function;
  • Insert the pin in the alignment holes located on the shaft and the gearbox and thus block the drive;
  • if a bobbin with fishing line is installed, you should unscrew it clockwise and find the nut to screw in the blade;

Algorithm of grass trimmer blade installation is demonstrated in details in the video below.

Modern grass trimmers, like the STIHL one, are easy to operate. To carry out the replacement of the cutting parts yourself is not too difficult.

When working, you should pay attention to safety in order not to cut yourself.

How to change a disk on a gasoline trimmer

It’s very easy to install a new or replace the blade on your brushcutter. Included with the tool always comes a pin, which should block the hole gearbox. We need this, so that the blade does not rotate, and we can unscrew the mounts for our nozzle. The key is to follow the safety rules. It is forbidden to change nozzles when the tool is on!

How to put a disc instead of a fishing line or a new blade on the grass trimmer:

  • Remove the plastic cover.
  • Blocking the hole in the gearbox with a pin. Gearbox and shaft cup have to be engaged at the same time. If all goes well, let’s move on.
  • Unscrew the bobbin through the attachment nut (clockwise). If the grass trimmer is used for the first time, the dust cover is unscrewed together with the construction. It’s there too.
  • Install the blade, so that its hole coincided with the center of the bobbin and tightly seated in it.
  • Put the dust cap back on.
  • Without removing the stop pin, tighten the nut (in the opposite direction).
  • Tighten the nut with any wrench. The harder, the better.
  • Put the blade guard back on.

To change the disc for the trimmer line on the gasoline trimmer, a similar procedure is carried out. Only instead of the nut you unscrew the bobbin. And in the last steps you return the nut and the duster.

Now you know how to put a blade on your grass trimmer instead of a fishing line, or install a brand new attachment. Share in the Комментарии и мнения владельцев what blades you use and how effective they are in controlling weeds. See you in the next articles!

How to remove the bobbin (bobbin)?

The design of automatic and semi-automatic reels allows you to change the line on them without removing the trimmer for grass.

And, if semi-automatic devices need to be partially disassembled by removing the bobbin, then automatic devices do not require even that, it is enough to insert the line for the trimmer and twist the head.

To remove the bobbin from an automatic or semi-automatic head on electric mowers with a top-mounted motor and on machines with a bottom-mounted motor, proceed as follows

  • Clean the surface of the head from grass residue;
  • With your fingers, squeeze the locks on the sides of the drum;
  • When the cover is free, carefully remove it;
  • Do not lose the spring and washers under the cover.

What blades to put on the electric and lawnmower

Before buying and installing a brushcutter blade, find out what they are and when they are used. Today, manufacturers offer the consumer a large number of types of these consumables. In general, all cutting tools designed for grass mowing can be classified:

The main material for the manufacture of trimmer blades can be plastic or metal. The use of such expendable elements depends largely on two parameters:

For safety reasons, manufacturers do not recommend putting steel blades on electric grass trimmers. Virtually all trimmers running on electric and battery power are equipped with plastic blades. Depending on the manufacturer, they can be solid disc-shaped, with several blades, or in the form of a special mowing head that provides for installation of removable plastic blades.

A straight boom in a gasoline grass trimmer and a curved one in an electric

To put a metal blade on the electric trimmer for grass does not allow its design features.

  • The curved boom of the machine reduces the distance from its working part to the mower’s legs. If the blades collide with a rock or other hard object, the grass trimmer will kick back to your feet.
  • The high torque mentioned above, when a metal blade hits a hard object, transmits a high load to the flexible shaft of the grass trimmer and its motor. Which causes their premature breakdown.
  • Handle of an electric mower most often doesn’t have a limiting strip that serves as a stop. That does not prevent the mower’s legs from injuring themselves.

Exactly these features make it possible to use plastic blades exclusively on electric-powered trimmers. When the blades collide with an obstacle, they break, thus protecting the mower’s legs from possible injury.

Plastic blades handle overgrown and dry grass well. They are capable of mowing nettles and burdock stems.

The use of metal blades only on gasoline trimmers is also due to the design features.

  • The straight boom design gives you more legroom for better safety.
  • Comfortable U and J-shaped handles for a firm grip. The D-handle of the brushcutter is fitted with a stop that rests against the mower’s leg to prevent the head from coming close to the legs when the cutting disc hits a hard obstacle.
  • Gasoline engine clutch provides optimum RPM acceleration. And if the blade hits a hard surface, it can absorb some of the impact.

Gasoline-powered grass trimmers with metal blade attachment are thus best suited for large areas. They can successfully cope not only with high coarse grass, weeds, burdocks and nettles, but also with bushes and young trees.

The shape of the blade on the blade trimmer for the grass has no effect on the quality of work performed. The speed does not depend on them either. Triangular, trapezoidal, rectangular forms are all a marketing ploy of manufacturers.

If you are planning to make hay, it is best to use a brushcutter with more blades. Pay attention to discs with eight teeth or discs with four big blades and four extra ones. Two and three blade blades will shred the grass very hard.

What is a lawn mower assembly?

Assembly refers to the connection of fully functional devices and assemblies, i.e:

  • Motor with controls and clutch (gasoline-powered only);
  • The correct size of the brushcutter is the drive shaft;
  • Handle or handle;
  • A blade guard;
  • shoulder strap or suspension system.

Tools and fasteners

Each appliance, regardless of its type, includes standard fasteners and universal tools.

The shape of the heads of all bolts, regardless of their diameter and length, corresponds to the tool that comes with the trimmer for grass.

In case of loss of any fastener, pick up its full analogue, if this is not possible, you can neglect the shape of the flat, but all other parameters, that is:

However, such an incomplete analogue will force you to use an additional tool in addition to the regular one, which is not very convenient. If you have lost the regular tool, then pick up the closest analogue or buy the same device in any store selling trimmers.

Process Description

The assembly process is described in detail in each unit’s instruction manual, and the shape and configuration of the finished units make it impossible to connect them incorrectly in most cases.

The main condition for a correct and fast assembly is the correct positioning of the blocks relative to each other, as well as the alignment of their holes.

Apparatuses with an overhead motor are more convenient to assemble on a table, where all the blocks can be arranged in the order of their docking.

Where there are several bolts connecting the parts, proceed as follows:

  • arrange both elements as they should look in the assembled state (when assembling a gasoline grass trimmer, put the motor on the table with the clutch up, then install the shaft with gears on it, the upper of which is the protection of the clutch bowl)
  • line up the holes;
  • tighten one bolt by torquing it 2-5 turns;
  • tighten the next bolts;
  • press the parts together to make sure they are properly positioned;
  • screw in (do not tighten) all bolts one after the other crosswise;
  • once again make sure that both units are positioned correctly;
  • tighten all bolts to the required torque (see operating instructions) in the same order, i.e. crosswise.

Order of proceeding

The most convenient is the installation of the largest blocks first, that is, the engine and the drive shaft, then to this structure mount the handle and the protective cover, and lastly put the cutting tool.

If the machine is shipped with the shaft disassembled, that is, the gearbox and the clutch are not installed on it, then assemble it starting with the shaft, because it is the most oversized part.

When assembling the shaft be sure to align the lubrication holes on it and the gearboxes, because lack of lubrication will quickly kill the shaft. Also align the splines on the drive shaft and gears, failing to do so and pushing parts on by force can damage them.

Be sure to check the presence of lubricant in the gearboxes and drive shaft, because in spite of the assurances of the manufacturer that all elements are lubricated and ready to work, it is often not true.

This is a particular sin of Chinese manufacturers of cheap machinery. If the shaft comes complete with gears, take some time to disassemble them to check the amount of grease. much cheaper to do it before the first start, than after a few days to change the drive shaft or buy a new trimmer for grass.

We also recommend that you oil the gears and shaft and change the oil in your four-stroke motor before the start of each season.

Don’t forget that the bottom gearbox and the crank mount must be positioned correctly on the drive shaft so that the gearbox shaft is facing down and the crank is facing up.

On all units with a rear-mounted engine, the handle is prefabricated and consists of:

First attach the connector to the shaft, then insert both handles into it.

Some trimmer models are equipped with handles with a connector sleeve, in this case:

Remember. handle placement and handle angles adjust to the operator, so if you are uncomfortable with your brushcutter or chain saw, adjust these details for you.

The right handle is for installing the motor controls, so for right-handed people put it on the right side. If you’re left-handed, put the right handle on the left side.

Assemble the cutting tool last. Use exactly the right shielding washers and cups for the selected tool.

If you install other gear protectors, strong vibrations may occur due to improper balance.

If it is more convenient for you to assemble the grass trimmer in some other sequence and you do not make mistakes, then do as you are used to. After all, this or that order is intended to make assembly easier, but it is not mandatory.

Main faults of the spool

Users of electric trimmer and lawnmower often face a problem related to the semi-automatic mowing head. Faults in the reel may be the following:

The line for the trimmer does not extend automatically

If the grass trimmer reel button lightly strikes the ground and the trimmer line does not extend, the reasons may be.

Variant 1. jamming has occurred, t.е. the filament is caught between the coils. This problem usually occurs if the user has wound the trimmer line unevenly, with overlapping coils, or with insufficient tension on the line reel. In the latter case, when the mowing head rotates at high revolutions, the cord begins to tighten under the influence of centrifugal force, which can result in inter-twist clamping of the line. To correct the problem you will need to take apart the spool on the trimmer and rewind the filament correctly, i.e. with even coils and good tension.

Variant 2. The ends are sticking out of the head. the trimmer line may not come out when hitting the ground, if its ends sticking out of the head are not long enough (short). In this case, the centrifugal force is not enough to cause the trimmer line to extend. Therefore, you need to stop the machine (turn off the engine or unplug the trimmer elektricheskogo grass trimmer) and pull the line for the trimmer manually, first pressing the button.

Variant 3. the line for the trimmer is soldered inside the mowing head. This causes the spool to freeze and does not turn when the button is pressed. Basically, this happens for several reasons: poor quality cord, overheating of the reel during prolonged operation of the machine, the impact of the line on hard objects.

  • In the first case, the third-party cord may be made of low-quality and easily fusible materials that cannot withstand the mechanical and thermal loading. That is why you should give preference to “brand-name” lines.
  • But if you bought a line of unknown quality for your trimmer and it often seals during operation, you can follow the example of some users who, after threading the line into the reel, moisten it with either silicone grease (from a spray bottle) or mineral oil. This procedure greatly reduces the likelihood of soldering between the coils of fishing line.
  • Also, the trimmer line can bind if it hits a hard object (stone, fence, dry twigs, etc.) while mowing.д.). As a result, it stretches a little and retracts back into the head at high speed. The friction heats the cord and causes it to stick together. The only thing you can do to fix this malfunction is to open the grass trimmer reel and rewind the line for the trimmer.

The line is lengthening spontaneously

There are situations when the user of the grass trimmer notices a very fast consumption of the line. At no time did he hit the button on the ground to lengthen the line. The reason that the line for the trimmer spontaneously lengthens, getting cut on a special knife on the hood of the device, may be the lack of a spring in the mowing head. Often beginner users of mowers, trying to load line for trimmer in the reel, forget to install the pressure spring in the head, or lose it altogether when opening the cover, and subsequently don’t even suspect about its existence.

Also, the line for the trimmer can be extended without a button, if the spring is loose. If the check of the spring confirms this fact, it is necessary to put some washers under it in order to reinforce its clamping properties.

How to use a chainsaw correctly?

The only way to extend the life of a grass trimmer is to use it correctly. Unfortunately, some manufacturers are not interested in the longevity of their products, that’s why some rules that help to consume the life of the machine more carefully are not included in the instructions for using a petrol trimmer.

For this reason, we recommend carefully following all the recommendations of this article, even if they are not in the user manual, because we made recommendations based on

  • the experience of many owners of such devices, which they have shared on the pages of various forums;
  • Advice of those who repair brushcutters;
  • recommendations from the manuals of trimmers most expensive and quality brands.

Since the operation of the grass trimmer involves not only mowing the grass, but also many other actions, we have divided it into the following topics:

  • Running-in of the engine.
  • RPM selection.
  • Mowing direction.
  • Choosing clothing and protective gear.
  • Safety Precautions.
  • Transportation and storage.

Running-in of an engine

Despite the fact that the engine of a newly purchased grass trimmer is running in and you can immediately start mowing, avoid maximum engine revolutions for the first 3-5 hours, because the final lapping of the piston/cylinder group parts takes place.

If you allow the engine to reach maximum RPM, there is a high probability of scoring on the walls of the cylinders, and this will lead to a sharp drop in engine efficiency, as well as greatly reduce its life.

RPM selection

Maximum engine torque occurs at 2/3 of maximum rpm and maximum power at 3/4 of maximum rpm. That is why grass trimmers are best suited for cutting in this range.

Reaching the maximum RPM will reduce your power output slightly. When you mow the grass, check the working sound of the grass trimmer and use this as a guide.

If the load turns out to be too high and the rpm decreases, increase the throttle with the corresponding button on the crank.

As soon as the load is relieved and rpm increases, press the accelerator pedal a little less to bring your engine back to optimum performance.

If you have never used a brushcutter before, and until the break-in period is over, mow only low and light vegetation that is easily handled by the line trimmer head. After the break-in period is over, the engine will be less afraid of high revs and you will be sufficiently skilled to run the engine by ear.

In addition, avoid running the motor at idle for long periods of time, because this reduces the lubrication of the crankshaft bearing, which can lead to overheating and seizure.

Mowing direction

When operating your brushcutter in maximum grass grip mode, move it so that it runs counter to the direction of rotation of the cutting attachment.

The blade or disc will then push the machine away from possible obstacles, so the grass trimmer will not come out of your hands.

It is also the way the blade or head throws the grass in front of it, so you can better feel the resistance to cut the grass and therefore avoid going too fast and the resulting movement:

The correct direction of mowing for most trimmers is from right to left. When moving backward, the grass trimmer continues to cut the grass, so there is an increased likelihood of a reverse impact, which can cause the machine to jerk violently. Therefore, when reversing, try to grab as little grass as possible to reduce the load on the machine and reduce the chance of kickback.

Choosing the direction of mowing in maximum vegetation capture mode is especially important when mowing:

Also, when trimming trees, try not to lift the cutting tool too much or turn it perpendicular, because this can cause the carburetor to malfunction.

This requirement does not apply only to brush trimmers, whose carburetors work equally effectively in any position.

Choice of clothing and protective gear

Grass trimmer is a high-risk device, so it is necessary to choose proper clothing and protective equipment to work with it.

If you are going to mow the grass, wear only clothing without any straps or fringes that might get caught in the rotating cutting tool.

If you wear shoes with laces, make sure they do not come undone. If you have long hair, limit the movement of your hair by wearing a hat or tie it up with something. Always wear glasses or a protective mask, because there is a possibility that the blade of grass will fly to the wrong place and hit the eye.
