Trimmer Stihl 55 Doesn’T Pick Up

25th March 2021

Possible causes of a problem with electric streamers

When using the trimmer, on which the electric motor is installed, problems with a set of revolutions also occur. But they are caused by completely different malfunctions in comparison with fuel streamers. The electric motor does not develop the required rotation speed in such cases:

if the voltage in the supply network is lower than the rated value for the electric motor by more than 10%;
in case of malfunctions in the soft start system (if this unit is installed);
when there are problems with the brush assembly;

Electric scythe brush unit

in the event of a burn out of the engine windings;
if wedging of rotating parts occurs.

To eliminate the problem with the voltage, you need to check its value with a multimeter or a tester in the outlet from which the electric power is taken. If it is less than the minimum permissible value, then to increase it, you will need to turn off all electrical appliances or install a stabilizer.

A prerequisite for the normal operation of the trimmer is the use of an extension cord with a cross-section of conductors corresponding to the power of the streamer motor.

To repair the soft starter, you will need to have the appropriate knowledge in electronics, so it is better to contact a service center. There they will decide on its maintainability or the need to replace it. You can check the button yourself or find the block diagram and try to figure it out.

Soft starter block

The brushes can wear out, resulting in loss of contact, which leads to stalling of the electric motor. The brushes are easy to replace. The features of the process are determined by the lawn mower model used. Along the way, you will also need to clean all contacting surfaces.

If the windings are burnt, if you continue to mow grass or bushes, the electric motor will quickly burn out. This will be accompanied by the appearance of a burning smell, up to the melting of individual parts. You will need to replace the electric motor.

Wedging of rotating parts occurs for various reasons. To identify and eliminate them, you will need to sort out the drive unit. There are models in which the number of revolutions is automatically adjusted depending on the load, increasing as it increases. at idle, the rotation speed drops.

The video shows an algorithm of actions to identify the most common reasons why the trimmer does not pick up the required speed:

Stihl trimmer does not develop speed

Stihl mower: operating tips

It is inherent in man to ennoble the place in which he spends the lion’s share of his time. Why does the Chinese lawn mower not develop speed? Trimmer Stihl FS 55 lawn mower Does not develop speed, stalls, we go through the carburetor Thank you for watching. City dwellers resort to the services of designers, or they themselves are trying to change something in their own home, acquire the latest furniture, wallpaper, so that, having come home after a difficult day, they can mentally rest and relax in a suitable environment.

Inhabitants of their own homes outside the town have completely different concerns and requirements. It is necessary to mow bushes, grass, various dead wood on time, to closely monitor the state of the personal plot and garden.

It is clear that this requires slightly different means of meriting comfort. And here a new brainchild of engineering comes to the fore. lawn mowers of the Stihl office.

Also, the ignition coil may be punctured in electrical equipment. In this case, the lawn mower will not start, or it will start and work intermittently, and then it stalls, or it will not start at all when it is hot.

You can check the coil‘s serviceability in the same way as when checking the spark: unscrew the candle, lean it against the trimmer body. If there is no spark when you jerk the starter, or it appears every other time, you need to change the coil.

Recommendations for use

It is necessary to take temporary breaks from work. lawn mower does not develop speed Diagnostics and Lawn mower trimmer Stalls at. This is necessary so that the engine of the device does not overheat and fail prematurely. lawn mower does not develop Dismantling the Stihl 180 chainsaw Stihl FS 55 is not gaining momentum? Yes. For amateur models, there is a break every 20 minutes for the same time. For professional mowers, work should be interrupted every 50 minutes, in which case the downtime should be at least 10 minutes.

It is necessary to monitor the condition of the fuel tank. If you do not plan to use the mower for a certain period of time, it is better to drain the remaining fuel from the tank compartment. This will help avoid damage to engine parts.

Features and best models

The mower of the Stihl company deserves a special mention, which is distinguished by its own versatility, reliability and ease of use. The company’s specialists have created many varieties of braids, with different features and applications.

For example, the range of lawn mowers is designed for mowing grass in large areas. For this, a self-propelled wheel system was developed, with the help of which it became possible to care for a large territory without spending a lot of time and effort. A lawn mower is perfect for decorating shrubs, giving them a certain artistic image and texture.

If you need a more subtle approach to trimming grass, for example, near flower beds or between trees, then the gasoline trimmer, designed for accuracy and precision, will do just fine. The company’s specialists have foreseen all the nuances and possible difficulties when working with braids, so they equipped them with nylon strings that prevent mechanical damage to trees.

A special AutoCut trimmer head is also used to ensure the normal functionality of the petrol trimmer string knives. This article will tell you about the of petrol hand-held lawn mowers and trimmers, it will also help you make the right purchase, which you will not regret.

There are two types of these mowers: amateur and professional models, designed to solve problems of a certain complexity. The first category includes models FS 38, FS 45, FS 55, etc. The features and differences of these tools are in the motor power (from 0.9 to 1.2 HP depending on the configuration) and the volume of the tank (approximately 0, 34 l).

The professional trimmers include Stihl FS 130 and FS 250. Let’s consider the characteristics and properties on the example of several mowers, in particular FS 38, FS 70 and FS 130.

Any braid has a knife on the protective cover, which cuts off the excess fishing line after winding, and the cable is no longer cut. If part of the cable breaks off, then the result is an imbalance, increased vibration. Bottom line: shaft drive bearings break.

Some tricks for working with the petrol trimmer

The summer time has come, and lawn-mowers clatter as usual on the personal plots. Great tool, powerful and mobile. With the help of a gasoline trimmer, you can cut the grass and get rid of the dried weeds. However, there are times when the lawn mower will not start, work intermittently or not at full capacity. There is certainly no time for work! And as they say, you pull the starter handle more than you mow.

Launching difficulties arise not only for seasoned lawn mowers, but also for new ones. How to be in this situation? There is only one way out. to heed the advice of experts and take advantage of their practical experience!

User’s manual

Particular attention should be paid to how to correctly carry out the first start-up and running-in of a gasoline mower. Competent actions will maximize the life of the trimmer and reduce the cost of its maintenance and repair.

Before you start the device for the first time, you will need to carry out several preparatory steps. Their list includes a visual assessment of the condition of the gearbox and the preparation of a high-quality fuel mixture, taking into account which oil should be filled in accordance with the manufacturer’s instructions and recommendations.

It is on the composition of the fuel that experts and experienced owners of gasoline trimmers recommend focusing attention. In situations with two-stroke engines, unlike four-stroke engines, the components will be gasoline and oil.

The proportions are indicated in the corresponding instructions attached to the equipment, or on the labels of fuels and lubricants. The annotations, among other things, indicate the type of fuel and engine oil recommended by the developers.

After all the trimmer assemblies have been inspected and the fuel has been properly prepared, you can proceed directly to starting it and then running in the internal combustion engine. This process includes the following steps:

the lawnmower must be positioned horizontally on the most level surface;
the lever controlling the air damper is moved to the closed position;
using a primer, fuel is pumped to the carburetor (a few movements are enough);
the ignition is switched on with the appropriate switch;
the starting cord should be pulled as smoothly as possible until resistance is felt;
the device is launched with several sharp jerks of the cord;
after the engine has started, open the air supply.

In some situations, the trimmer may not start or stall right after starting. In such cases, it is necessary to slightly open the air supply to the carburetor and try again. After a positive result, let the motor run for at least 5 minutes in idle mode.

Using the lever, the air supply should be set so that the line spool or knives remain stationary. After the engine has completely warmed up, the throttle is opened by moving the said lever to the position marked with the ON icon, and the gas regulator is pressed halfway for 20-30 seconds. In the next step, the trigger is released and the trimmer will idle for approximately 40 seconds. Such manipulations are repeated for 10-15 minutes, after which it is necessary to take a 20-minute break.

By repeating the above steps, further running-in of the internal combustion engine of a gasoline mower is carried out. The next stage is the gearbox running-in, for which you will need to select the appropriate area with soft grass. The latter is beveled for 5-10 minutes with periodic podgazovki (1/2. 2/3 of the maximum speed). This cycle is repeated several times with an interval of 20-25 minutes.

Sooner or later, trimmer owners have to deal with the need to change the line. This is an integral part of the operation of such equipment. There are several ways to update the cutter in question. The simplest option includes the following manipulations:

remove the head from the trimmer and clean it thoroughly;
unwind the required length of the fishing line (2-3 meters is recommended) and bite it off with pliers;
bend the fishing line so that one end is 15 cm longer than the other;
put the bend on the spike located between the grooves of the coil;
wind the fishing line simultaneously in two directions, temporarily fixing it in the grooves (the direction of winding is indicated by the arrow);
thread the ends through special holes in the lid;
insert the spool of new line into place and snap into place.

Often, when using Stihl lawn mowers, it may be necessary to adjust the carburetor. If you have the appropriate knowledge and skills, you can do it yourself. At the preparatory stage, you will need to thoroughly rinse the air filter. It should be noted that it is highly recommended to do this every ten hours of mower operation.

Adjustment is carried out by three screws, one of which is responsible for fuel supply. It is twisted until the internal combustion engine starts to stall. Then the screw should be unscrewed by a quarter of a turn (if the motor has stalled, then by 1/2). After starting the trimmer, continue to unscrew the same screw until the internal combustion engine starts to work stably at increased speeds.

For some reason, the Stihl electric scythe does not develop its full power

When using the electric trimmer, rpm problems can also occur. The reasons here are completely different than those of fuel braids.

You can fix problems yourself

the trimmer does not develop the required power because:

the voltage in the network is below the required minimum for the device more than 10%;
there was a failure in the soft start (if there is such a system);
there was a malfunction of the brush assembly;
the motor winding is burnt;
rotating parts sometimes jam.

To adjust the voltage, you should first check its power. If it does not meet the standards, you should increase it with a stabilizer.

Repair of the soft start system is carried out only in the service center.

Note! If the brushes are worn out, you just need to replace them. When installing new ones, it is recommended to clean all surfaces with which they come in contact.

To adjust the voltage, you should first check the power.

If the motor windings are burning, you need to change the electric motor.

Jamming of rotation parts can occur for various reasons. To eliminate them, the entire drive assembly should be revised.

For your information! The latter problem may arise with another unit of this company. the Stihl secateurs, and sharpening the disc with scissors will be its solution.

Diagnostics and elimination of problems of electric motors

Trimmer malfunctions can be as follows:

insulation failure or cable break;
malfunctions in the area of the cutting tool;
damaged socket or plug.

To cope with these breakdowns, you do not need to disassemble the entire apparatus.

In case of serious engine malfunctions, you will have to disassemble it. To do this, you need to unscrew a few screws. Having gained access to the details of the motor, you need to carry out the following actions:

check the degree of wear of the brushes. unsuitable parts will need to be replaced with new ones;
ring the motor winding. the resistance must be high;
check the stator and rotor. to test the rotor winding with a multimeter, measure the resistance: large deviations from the norm indicate a malfunction, the absence of resistance on the stator winding also indicates a breakdown (in a similar way, the stator case is diagnosed).

Low rp problems are common with cheap trimmers. However, if improperly maintained, this also affects hand mowers such as the Huter, Patriot 3055, Echo.

Features and best models

The professional trimmers include Stihl FS 130 and FS 250. Let’s consider the characteristics and properties on the example of several mowers, in particular FS 38, FS 70 and FS 130.

Tips for choosing

In accordance with the current statistics, it is the gasoline models of mowers that are in the greatest demand. This is largely due to their mobility and functionality. However, when choosing a specific model of equipment, a number of other parameters must also be taken into account. In such situations, it is useful to compare lawn mowers with other types of trimmers.

Electrical devices are connected to a household mains with a voltage of 220 V. Such machines do not pollute the air due to the absence of exhaust gases. No less important points will be the minimum noise level and the relatively low weight. At the same time, the area to be treated is significantly limited by the length of the carriers used.

Cordless models are by far the least common grass trimmer. The electric motor of these mowers is powered not from the mains, but from the battery, which ensures maximum mobility. However, the operating time of the equipment is limited by the battery charge and averages 35-45 minutes. Another important point is the relatively high cost of battery models.

When choosing a specific model of a gasoline trimmer, it is necessary to take into account its technical characteristics. So, low-power devices are equipped with reels with fishing line

On more resourceful and powerful models, knives and cutters can be used as cutting elements.
