How to wind a spring on a Stihl trimmer
The first way
Line bent in half
The prepared segment (in this case, it is 4 meters) is bent approximately in half. one segment should be 15-20 cm longer, and inserted into a special slot located on the dividing partition.
The line is inserted into the slot
The line is wound in the direction determined earlier. This is done in an interference fit, the line is neatly distributed. In this case, you need to wind a segment that is longer in the section that is closer to the button.
There are designs that do not provide for dividing the coil into two sections. This does not change anything, the line is wound in a similar way. You just need to make sure that the segments do not overlap with each other.
The first should end that section, which is located at the bottom of the coil, i.e. the one closest to the fixing holes.
This tip fits into the corresponding hole in diameter. The line is securely fixed.
The line is securely fixed
A long segment is wound another half turn. There he is similarly fixed. In this case, the segment crosses another section of the coil.

The fixed ends of the coiled line are inserted into the holes in the trimmer spool body.

The coil is attached to the body. The ends of the fishing line are pulled with effort so that the fishing lines previously fixed in the holes of the reel jump out from there. It is easily identified by the characteristic sound (click).

The line was changed successfully. In this case, you need to put it back on the trimmer and you can start mowing the grass.
It should be repeated, there is no need to remove the spool from the trimmer. this was done for clarity of the process of replacing the fishing line. You can disassemble the spool in place, wind it on the spool and put it back.

Tips so that they do not hit the trimmer cover can and should be trimmed.
Method 2. two segments
Two coiled line lengths
fundamentally no different from the method The only difference is two wound pieces of fishing line, instead of one.
The end of each segment is folded
The end of each segment is folded.
Two special fixing sockets
There are two special fixing sockets on the coil (see picture above).
We start winding the line
They hook it with a hook formed earlier on the fishing line, and begin to wind the fishing line.
Winding is carried out in a special order
The winding must be carried out in the following order: first the lower line, i.e. the one that is closer to the fixing holes at the bottom of the coil, and only then the top one, i.e. the one that will overlap the bottom section.
The bottom line is reeling
The tips are cut into the holes in the trimmer spool body. They are pulled up until they click, which means that the line has come out of the latches.
The tips are threaded into the holes in the trimmer spool body
The coil is fastened into the body. The line in the spool has been replaced.

Changing the line in the trimmer: 2 easy ways
A trimmer is a necessary and useful tool for a summer cottage and a private house. Many people own and actively use it, but not everyone knows how to replace the line in the trimmer, especially at first.
In this manual, we’ll walk through the entire replacement process step by step. Looking ahead, there are two ways to line the trimmer spool. There is no fundamental difference. the difference lies in the fact that in the first case one line will be refueled, folded in half, and in the second there will be two such lines.
Preparing for replacement
We disassemble the trimmer spool
For clarity, the mowing head (spool) was removed from the lawn mower. To replace the fishing line, you do not need to remove it, everything is done locally. It doesn’t take long.
We disassemble the trimmer spool. it rests on the latches. Remove the cover by pressing on the latches. If you do not have enough effort to do this with your hands, then use a screwdriver.
The spool consists of the following:
- Spring case
- Cover with locking latches
- Button coil
The principle of operation is as follows. By pressing the button, the spool presses on the spring and comes out of the locking grooves in the spool cap. Holding in this state, the reel can be twisted, thereby adjusting the length of the line. When the button is released, the body spring returns the coil to its original fixed state.
Disassembled trimmer spool
On the bottom of the reel there are several holes for different diameters of the lines. They may differ from trimmer manufacturer. In some cases (like here) they are signed, in others they are not.
These holes are needed to fix the line when replacing it. After winding the fishing line on the bobbin, the ends of the latter are inserted into them. This is necessary so that the scaffold does not unwind when the coil is installed in the trimmer body. In other words, it makes it easier to change the line.
Holes for fixing the line
There are models without specifying the diameter of the consumable. Then, in order to find out what the maximum diameter of the scaffold can be used, it is tried on along the holes for removing the fishing line from the trimmer spool body (see figure below).
Fitting on the holes of the line output
The reel has two line sections separated by a baffle. They may not exist. They are needed only to delimit and facilitate the winding of the consumable.
Two sections for fishing line
First, they are determined with the required length of the loess. The latter is wound into one of the sections of the coil so that it does not go beyond its limits. In this case, 3 mm was wound, the length turned out to be about 2 meters. Those. for two sections you need a 4-meter segment. this is for the 1st method. For the second method, you need two segments of 2 meters each.
Determining the required line length
Now you need to figure out which way you need to wind it. To do this, many trimmer manufacturers apply special designations to the spools, such as in the figure below.
Special designation on the reel
If no such designations were found, then you need to pay attention to the spool body. There is necessarily an arrow that indicates the movement of the mowing head. The line is wound in the opposite direction.

The device and principle of operation of the starter on the trimmer
The gasoline engine is, in principle, the main part of lawn mowers.Its power is in the range of 0.5-2.5 hp. The movement from it is transmitted to the shaft, which is inside the hollow rod, and then through a gearbox consisting of gears, already a fishing line or knife (working body).
Also, lawn mowers have the following elements:
- protective casing;
- lever;
- belt designed for the convenience of using the device;
- starter used to start a gasoline internal combustion engine.
All parts of the lawn mowers are presented in the photo below.
The trimmer starter is an integral part that starts the engine. He is shown separately in the two photos below.
The starter mechanisms of different models of lawn mowers work on the same principle: when the engine starts, the protrusions marked with 1 in the photo above engage with the pawls 3. When the engine starts to work, they return to their previous position due to the influence of centrifugal force. Wire 2 also plays a similar role.
The process of returning to the initial position of the elements of the mechanism occurs due to the presence of a spring wound around the axis. It unfolds when the rope is pulled. After releasing the cord, it is pulled in and wound up due to the coiling of the spring. During the start of the internal combustion engine lawn mowers, the starting mechanism turns its shaft until it starts to work (starts).
Today, gasoline lawn mowers are equipped with two types of starter mechanisms:
- manual;
- electric.
The first option is much more common.
The trimmer starter can operate without breakdowns for a long time. It is impossible to clearly indicate the period of uptime. Everything is determined by the initial quality of the device and adherence to the rules for handling it.
Disassembly of the starter unit
The launch mechanism is disassembled in order to install new parts instead of broken ones in the following sequence:
- unscrew with a screwdriver the screw fixing the pulley with the starter cover;
- take out the spring and antennae;
- carefully remove the pulley (you need to turn your head away or work, wearing glasses and gloves first);
- determine why the trigger is broken;
- if the spring has collapsed almost completely, then it is replaced;
- when the spring comes out of the hook, it is installed in its original place, bending the antennae in front of this (the photographs show the laying process);
- after the spring plate is installed inside the groove, carefully twist it.
To change the spring, you must work carefully and carefully: it can accidentally burst under the influence of the force caused by installing it in place. Even if you carefully remove the roller, the spring strip very quickly flies off the reel and can injure your hand with its sharp edges.
It is not always possible to immediately put the spring plate in its original place. It often slips, so attempts must be repeated until the desired result is achieved.
Spring tension
After installing the spring, tighten it. To do this, perform the following actions:
- remove the handle from the starter cord;
- then the rope is inserted into the reel groove;
- tension the spring by rotating the coil in the opposite direction to the clockwise direction (winding);
- make the required number of revolutions specified in the operating instructions for the used trimmer model and corresponding to the length of the cord used;
- at the very end, the rope is threaded into the hole intended for this, located in the starter cover;
- put the handle in place, fixing it with a knot.
If, after repair, the spring continues to fly off, then you can get rid of it in the following ways:
- squeeze a piece of the plate suitable in size into the groove at the location of the spring hook;
- drill holes on both sides of the groove in the spool, into which to insert the spring hook and fix it with a wire.
Removal and disassembly of the starter, replacement of broken parts
To repair the trimmer starter, you will first need to disassemble it, and then assemble it. This process is not particularly difficult. For work, you need a screwdriver with a tip of the desired shape.
Everything should be done carefully, observing safety precautions, mainly so that the spring does not injure the master in case of an accidental departure.
How to repair a trimmer starter
Petrol trimmer starter repair may be required at the most inopportune moment. In this case, the problem can be solved in two ways: replace the broken part or change the entire unit. The latter option is more expensive. To repair the device with your own hands, in most cases, you will only need a screwdriver with the appropriate tip from the tools. Repair work does not take much time and does not require special knowledge. It is enough to know the device, the principle of operation, the nuances of assembling and disassembling the starter on the trimmer in order to achieve the desired positive result.
The main malfunctions of the trimmer starter
It is not difficult to determine the cause of the breakdown of the triggering device. There are several main options:
- break of the cord (rope);
- when the spring breaks or disengages.
The above details are shown in the photo below.
It may happen that the starter mechanism is accidentally broken. The consequences will be disastrous if the broken rope is wound around the flywheel of a working internal combustion engine: then the spring will burst, the pulley will break. But such cases, when a complete replacement of the starter unit is required, are extremely rare. In most cases, to fix the mechanism, it is enough to install a new spring or replace the cord.
Starter assembly
The assembly of the starter unit is carried out in a number of stages:
- the coil is turned over, setting it so that the spring bend fits exactly into the groove of the body, as in the photo below;
- two washers are laid, between which a spring is placed;
- put in place the cup with the antennae;
- tighten the screw (photos below).
When doing the described manipulations, it is imperative to put two washers. If this is not done, then the spring will eventually damage the plastic cup, and when it is pulled up, wedging will begin. Because of this, there is a feeling as if the spring has flown off. To eliminate this drawback, you need to install this part of a greater length or an additional washer.
When such parts are not available, you can simply unscrew the screw a little, and the starter unit will start working without wedging. But this option is temporary. it is better to repair it with high quality as soon as possible.
Preparatory stage
The repair of any equipment should begin with the preparatory work, and the Stihl 180 saw is no exception. At the preparatory stage, before the Stihl 180 chainsaw is disassembled, it is necessary to remove the side cover, chain and tire from the chainsaw. Further, using a compressor and a brush, you need to clean the chainsaw from dirt, sawdust, oil drips and other things.
When cleaning the saw, special attention should be paid to the place where the chain saw drive sprocket is located, since this is the most polluted area.
In places with a large accumulation of oil, can be washed with clean gasoline.
Dismantling the clutch and oil pump drive
Before disassembling the clutch, the drive sprocket must be removed. To do this, carefully remove the lock washer from the grooves on the shaft and remove the sprocket and needle bearing.
With a high head 19, you need to unscrew the clutch. The thread on it is left-handed, so it unscrews towards the tire, and not the back of the Stihl 180 saw.
Having unscrewed and removed the clutch, you need to immediately remove the reflective plate and the oil pump drive, this is easy to do, because they are put on the shaft without any fastening.
Removing the starter
At the next stage, the upper housing cover is removed and the 4 starter mounting screws are loosened, after which it is necessary to remove the oil tank and fuel barrel covers. The starter is removed quite simply and there should be no problems.
After removing the starter, the opened inner cavity of the chainsaw must be cleaned, since usually there is a large amount of compressed small sawdust on the body under the starter.
Actions in the event of a malfunction in various parts of the unit
Unpleasant phenomena such as loss of power, lack of connection, and no-load support are common.
The reasons for this behavior of the tool are the malfunctions of the chainsaw carburetor. This is expressed in contamination with dust particles, sawdust. Such a breakdown can be eliminated without problems on its own.
Carburetor cleaning is carried out using:
- a small amount of gasoline;
- Phillips screwdriver
- brushes;
- heads, size 8.
The sequence of steps when performing repairs:
- To start repairing the carburetor, they begin with cleaning from dirt and dusty particles, small wood. A brush is used for this. When the surface is completely free of debris residues, the repairer removes the cover, after which the filter.
- The air collector is released after unscrewing the fasteners of the air filter. The user now has access to the accelerator and traction. The accelerator lever is removed as soon as the throttle is lowered by pressing down with a finger.
- The carburetor moves out of the seat after the choke lever is removed and closed. Then the wire is removed and pulled towards itself to stop the engine. A photograph is taken of the plastic lever, which is the place of attachment of the wire.
- It is lifted from the left. As a result, the carburetor is released, which makes it possible to pull it out and clean it. For these purposes, it is convenient to use a compressor. In its absence, the parts are washed in pure gasoline.
Dismantling the Stihl chainsaw. video
The process of assembling the saw carburetor is carried out in the reverse order. If, after this process, smoke appears from the muffler and the saw engine does not start well, then you need to make sure that there is a spring located under the lever needle.
The spring shuts off the fuel supply. In its absence, there is a spontaneous “overflow” of fuel into the spark plug. It is important to ensure that the spring is installed in its place, and make sure that the spark plug is working.
If the candle is flooded with gasoline, then it should be dried. To do this, the part is unscrewed, the excess fuel that has got inside is drained through the existing hole. The candle dries for more than half an hour. Then it is installed in place, and the chainsaw is brought into working condition.
Insufficient contact between the high-voltage wire and the end of the plug can also be one of the causes of tool breakage. Stihl chainsaw parts can be repaired by replacing problem parts.
For example, if a candle fails, it is replaced with a reliable one. Chains, sprockets, tires are subject to rapid wear. They solve anti-vibration problems in the chainsaw device, so they are replaced urgently. It is recommended to keep such spare parts in stock.
The most common types of chainsaw malfunctions
The operation of the Stihl 180 chainsaw is carried out in accordance with the instructions supplied with the tool. The user turns on the starting system after being convinced of the presence of oil, gasoline, and ascertaining the correct tension of the chain.
Working with the tool begins after it is securely held in your hands. If a tool failure is detected, it is necessary to determine what caused the malfunction of the Stihl chainsaw.
The reasons that caused the malfunction of the tool can be:
- the appearance of a leak in the oil system;
- formed breaks in the crankcase cord;
- carburetor malfunctions;
- air entering the crankcase through the oil seals;
- worn condition of the worm gear in the oil pump;
- no spark appears at the ignition cross section;
- deterioration of the driving sprocket;
- violation of the integrity of the eyelet under the control lever.
To carry out an independent repair of a broken Stihl chainsaw, tools are used that are in stock with each consumer.
It can be:
- screwdrivers;
- socket and wrenches;
- hexagons;
- vacuum gauge used to determine defects in oil seals, carburetor, crankcase;
- air compressor used for purging and cleaning components and assemblies;
- T-key STIHL Torx 27;
- stopper limiting the course of the crankshaft;
- bearing puller.

Identification of problems in starting the unit
There may be a problem in which the Stihl 180 does not start. As a rule, it is associated with a breakdown of the starter. In fact, the unit does not start after pulling the cord.
The reasons for the refusal to start the starter can be:
- Spring failure.
- Cracked or broken pulley.
- Burst rope for launch.
Before you find out the reasons for the breakdown, and start repairing the chainsaw starter, the chainsaw body is removed. To do this, unscrew the screws that hold the cover with the starter.
In this case, screwdrivers or special tools are used. A visual inspection of the starter reveals the reasons why the tool did not start.
Damage to the pulley by cracks and ruptures affects the performance of the tool. Detection of mechanical failure or defects in the place where the soft release spring is attached.
Vulnerable is the place of attachment, as well as the tip of this spring inserted into it. If malfunctions or damage to individual parts of the starter are detected, they are replaced with new ones.
Disassembly and maintenance of the piston system of the Stihl 180 chainsaw. video
It is possible to repair the unit with high quality if the parts are in full compliance with the brand of the chainsaw. The same scheme for replacing spare parts applies to saws during DIY repair.
Stihl MS 180 is a reliable and unpretentious tool, but sometimes it requires repair, like any technique. In this article, we will consider how the Stihl MS 180 chainsaw is disassembled, which is necessary in the event of an engine overhaul.
Special attention to the oil pump
The oil supply can be interrupted for various reasons. The most common malfunction of the oil pump. This can be verified by the condition of the chain lubrication.
If the supply of oil to the chain is interrupted, it becomes dry or excessively wet. these are signs of poor operation of the oil pump.
To eliminate the problem, the oil supply hose is inspected. The junction of the hose with the oil pump and the tank is inspected for tightness.
We service the oil pump of the chainsaw. video
Such problems appear as a result of mechanical damage to parts of the oil system. To get to the problem area, this unit is disassembled.
If the repairer is convinced of the damage to the hose, then it should be replaced. However, depending on the degree of damage, it is possible to seal with special compounds.
Before sealing, the surface is washed and degreased. By repairing stihl ms 180 on their own, the consumer has the opportunity to dramatically save.
Method 2. two segments
Two coiled line lengths
fundamentally no different from the method The only difference is two wound pieces of fishing line, instead of one.
The end of each segment is folded
The end of each segment is folded.
Two special fixing sockets
There are two special fixing sockets on the coil (see picture above).
We start winding the line
They hook it with a hook formed earlier on the fishing line, and begin to wind the fishing line.
Winding is carried out in a special order
The winding must be carried out in the following order: first the lower line, i.e. the one that is closer to the fixing holes at the bottom of the coil, and only then the top one, i.e. the one that will overlap the bottom section.
The bottom line is reeling
The tips are cut into the holes in the trimmer spool body. They are pulled up until they click, which means that the line has come out of the latches.
The tips are threaded into the holes in the trimmer spool body
The coil is fastened into the body. The line in the spool has been replaced.

Replacement instructions. how to insert the line
It should be noted that the reels in mowers can be different:
- for functioning with one antenna;
- for functioning with two antennae;
- the line must be threaded through the through hole, which is located inside the element.
And do not confuse this part with an extension cord for a lawn mower on a reel, because despite the similar name, these are two completely different elements.
The mini chainsaw is designed for light work and people who prefer to hold the device with one hand.
This article will tell you about how much the ZIL 130 dump truck weighs and what this transport is capable of.
Read here //machinspec.com/lesozagotovitelnaya/benzopila/stanok-dlya-zatochki.html how to assemble a machine for sharpening chainsaw chains with your own hands quickly and easily.
In the first option, winding the cutting element is very simple:
- There is a locking tab on the inside of the spool element.
- One tendril of thread is inserted into it.
- It is necessary to thread the nylon thread in the direction opposite to the rotation of the spool element.
- You will need only 2 to 4 meters of fishing line. When the winding process is complete, put the small end of this cutting element outward and fix it in the groove, which is necessary for fixing the line so that it does not unwind during the operation of the mower.
- If there is no special groove, then the end should be held by hand so that the cutting element does not unwind during further assembly of the element.
- At the last stage, it is necessary to thread the outer end of the thread into a special hole located on the outer part of the element. The spool can then be inserted into the mower.
When the roller is working with both ends of the plastic filament, then the following steps must be taken to thread the line into the mower:
- Inside, on the spool, you will see how many slots there are for winding (two or one). If there is only one groove, then both ends of the thread will be guided through this groove. If there are two of them, then the antennae are laid out separately. each in its own notch.
- It is necessary to unwind from 2 to 4 meters of polyethylene thread and thread its two ends into the hole.
- Wind both threads in the opposite direction to the rotation of the drum.
- When all the line is wound, the ends should be fixed in the grooves or held by hand.
- Both ends are threaded into the eyelet from the outside of the roller housing.
- The drum is then collected and inserted into the mower.
Tips and steps for changing the line on video.
To insert line into a lawnmower that has two grooves on the spool, you must use the previous threading method for this polyethylene thread. In this case, each of the ends of the line will be wound along its own groove. All other actions are similar to the previous process.
The spool element or roller can have a completely different design from the previous two options. The line can be threaded through the eyelet, which is through and located inside the reel. In this case, you do not need to disassemble the roller drum and manually wind the polyethylene thread.
The polyethylene thread is threaded through the hole and rotated by pressing a special button. This button is located on the body and is intended for the operation of the technique, so that it is possible to release the line as it wears out.
Do not worry that the polyethylene thread will wind in the wrong direction, since in this design it can only spin in one direction.
Safety engineering
To quickly and safely change the line on the reel of the mower, it is necessary to observe safety precautions. Before removing the reel to wind the line around the mower, the technician must be disconnected from the power supply (if the mower is powered by electricity). Here I would like to mention the reliability rating of electric lawn mowers, which will help you choose a safe helper.
Another important safety rule that must be observed is pressing the lock button. You can find out its location on the vehicle body using the operating manual. For example, you can find the operating instructions for the manual petrol lawn mower here.
Do not forget that the cutting element needs to be adjusted. There is an adjustment button on the body of the unit. If the process does not start automatically and the thread tension has been released, then the button is clamped, and the fishing line is pulled out of the spool with force.
Remember that changing your mower’s line is an important and responsible process. It is necessary to carry out everything in stages, and only special polyethylene fishing line should be inserted into the spool. An iron cable, some high quality wire, or even a reinforced fishing line will not work here.
Watch the video instruction.
Which line to choose to refuel the lawn mower
The thickness of the polyethylene thread depends on the model of equipment and varies from 1.2 to 4 mm. She may be:
- with a round cross-section. this is the most durable material for mowing grassy plants;
- with a curly section. used for mowing soft plants;
- twisted. used for thin grass;
- professional type, not suitable for all models of equipment.
To change the line on a lawn mower, you need to purchase a cutting thread that will be ideal for the type of mower.
You can soak the thread in a bowl of water for a few minutes to increase elasticity and strength.
If you have a summer cottage or a large plot of land near your individual house or cottage, then for the convenience of cleaning grass and weeds, you must use a lawn mower. In case you are thinking of choosing an electric lawn mower or a gasoline one, then click here and you will find comparative characteristics of different models.
Over time, the line on the mower wears out and needs to be replaced. you can do this yourself. The choice of this polyethylene thread is necessary depending on the model of the mower. It is also worth keeping an eye on the rest of the unit’s details, here, for example, you will find information about Craftsman lawn mower knives, which also wear out and can lead to irreversible consequences.
The device of the reel into which the fishing line is inserted is very simple. But it differs depending on whether the coil is operating with one or two tendrils of thread. It is important to observe safety precautions when changing the line in the reel.
Line arrangement in the mower
The device of the element on which the nylon thread is wound is very simple. This element is called a coil. It has two “tracks”. the upper and the lower. Between these tracks there is a special partition with a recess. A fishing line is wound on these tracks. It must first be pulled through the recess.
In order to be able to pull out the coil without obstacles, it is necessary to unscrew the special button, which is located on the mower body.
