Starter grass trimmer repair.
Major malfunctions of the grass 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.
How to repair a trimmer starter
The petrol grass trimmer starter may need to be repaired at the most inopportune time. 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 an 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 device and principle of operation of the starter on the trimmer
The gasoline engine is, in principle, the main part of the brushcutter. 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, the lawn mower has the following elements:
- protective casing;
- a belt designed for the convenience of using the device;
- starter used to start a gasoline internal combustion engine.
All details of brushcutters 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 various models of petrol brushes work on the same principle: during the start of the internal combustion engine, the protrusions marked in the photo above with the number 1, engage with the pawls 3. When the engine starts to work, they return to their previous position due to the influence of centrifugal force. A similar role is also played by wires 2.
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 of the lawn mower, the starting mechanism turns its shaft until it starts to work (starts).
Today, gasoline brushcutters are equipped with two types of starter mechanisms:
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 the observance of the rules for handling it.
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 grass trimmer model and corresponding to the length of the cord used;
- at the very end, the rope is threaded into the hole provided 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:
How to Fix Recoil Spring on a WeedEater
- 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 coil, into which to insert the spring hook and fix it with a wire.
Assembling the starter
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 damage the plastic cup over time, 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.
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 the screw fixing the pulley with the starter cover with a screwdriver;
- 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 has 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 before 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.
Removal and disassembly of the starter, replacement of broken parts
To repair the grass trimmer starter, you will first need to disassemble it and then reassemble 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.
Do-it-yourself repair of the starter of a gas drill, lawn mower, grass trimmer
Today, we will consider the most common case when the breakdown is not so serious and show how to repair the starter with our own hands if the cord breaks off without any destructive consequences or does not wind up due to the fact that the spring inside just flew off, out of engagement. At least initially I want to believe in it. But in order to find out whether this is so or not, you will need to disassemble the starter.
Installing or replacing the starter spring for brushcutters, motor-drills, grass trimmers
But what if everything is in order with the rope, and the reel (pulley) of the starter does not unwind? Let’s consider this issue step by step using the example of the starter of the gasoline ADA GroundDrill motor drill, which has a pulley with two metal antennae for 2 hooks.
In the case of other types of manual starters of a similar design, which are widely used in gasoline brushcutters, trimmers and motorized drills, the whole process of repairing a starter will look similar, differing only in some nuances.
Starter repair: disassembly
We unscrew the screw with which the pulley is attached to the starter cover. We take out the antennae, the spring. We pull out the pulley itself carefully so that the spring does not bounce into the face. Even with the most careful disassembly, it usually immediately flies out of the coil and abruptly unfolds into a long metal strip or twists into rings.
Pull out the white starter coil carefully. do not get hurt by the spring!
If the spring bursts or one of its hooks breaks, then repairing the starter will not work simply and quickly. the spring needs to be replaced. In order not to spend money on buying a new starter, you can search only for it on sale.
If the starter spring simply breaks off, that is, one of the hooks is out of engagement, it is enough to insert it, if necessary, slightly tightening the hooks more tightly (just do not break it off!) Install the spring with an outer hook into the pulley groove and start twisting it, while holding with your fingers inside the coil and preventing it from jumping out of there.
Pressing the spring to the pulley, wind the spring inward in a circular motion
It may not seem so easy to insert the starter spring the first time, but everything comes with experience. With a little practice, you can easily wind the spring into the pulley in a maximum of a minute.
The starter spring is wound. It remains only to assemble the starter and charge the spring to the desired value.
How to repair a gasoline tool starter with your own hands?
In the case of a break in the starter cord, everything is clear: we take out the old rope, take it that is suitable in length and thickness (linen is possible), pass it through the hole in the reel, tie a knot. Next, we charge the spring to the number of revolutions we need, only after which we fix the handle. and voila! details on how all this is done is clearly shown below.
How to assemble a starter?
The most important thing in the process of self-repairing a starter is to assemble it correctly.
After the spring is fully wound, you need to carefully turn the coil over and insert it into the starter housing so that the second spring hook enters the housing groove.
Installing the pulley (in this photo. black), we look through the hole in it so that the spring hook falls into the groove on the starter cover
Then, if there is a spring under the screw, we first install it, not forgetting to put washers on the bottom and top of the spring.
Carefully insert the cup with antennae into the grooves of the coil and tighten the screw.
Make sure that the washer on the spring does not fall out. Why is it important? The fact is that the spring scratches the plastic cup with its end, as a result of which the latter wears out and begins to press the screw more tightly against the coil. For this reason, a situation may arise that is very similar to a spring break: the handle is pulled out of the starter, but does not come back. However, loosen the starter screw this problem disappears. It is easy to fix such a starter malfunction: just select a spring of the same diameter, but slightly longer, or put an additional washer. If we just loosely tighten the screw, then it will twist and fly out, and this will already increase the likelihood of a spring break, since the pulley will not fit snugly enough to the starter housing.
We screwed the coil to the body, now we need to tighten the spring. Before this, it is necessary to remove the starter handle from the rope in advance. If the knot is too strong, then you can simply cut it off or try to untie it, for example, using a pair of pliers. This is so that after you have cocked the spring, you can thread the rope through the hole in the starter cover. The other end of the rope must be fixed in the reel even before it is installed in the body; the rope does not need to be wound onto the pulley before pulling the spring. do this after.
Before cocking the spring, estimate how many revolutions of the reel the rope should be wound. Let’s say the length of the rope at the starter of the Ada GroundDrill-5 motor drill corresponds to 5.5 turns around the reel. In this case, we make at least 6 turns of the coil in the direction opposite to the direction of winding.
So let’s get started. Without winding up, insert the rope into the groove in the reel specially designed for it. Everything is ready, we proceed to tensioning the spring. To do this, we rotate the coil counterclockwise. in the direction opposite to the direction of rotation of the coil when winding the rope. It is more convenient to do this not on the knee, but by pressing the starter with one hand to the floor, and with the other turning the reel directly by the rope attached to it. If the experience is not enough, then you can rotate the pulley itself with both hands, but the rope will get in the way, which can create additional inconveniences. After the required number of revolutions has been made, we pass the end of the rope through the hole in the starter cover, put on the handle, and fasten it with a knot. It is more convenient to do this together with a partner, so that the end of the cable does not accidentally reel inside the starter.
By the way, on your own, you can make some modifications to the design of the starter in order to more reliably fix the end of the spring inside the coil. At this point, who has enough imagination for that. Now I will explain why this is needed. It often happens that the spring in starters of this type, after the first such self-repair and installation of the starter on the unit, flies again after a few jerks. the hook does not hold in the coil groove. And this is despite the fact that the coil almost snugly adheres to the starter cover and the spring there certainly should not hang freely up and down, and even more so until the spring leaves its engagement. It turns out that when the cable is pulled, the spring pulls out, pulls it out of the groove. In this case, you can do the following: cut out a narrow strip of metal, which, in thickness, could squeeze tightly into the groove of the coil along with the spring hook itself. So the hook will not dangle freely in the groove, which means it will not be so easy for it to break out.
A metal plate tightly inserted into the gap between the spring hook and the groove walls will securely hold the spring
Another solution to the problem: drill small holes in the coil on both sides of the groove and, inserting the spring hook, fix it with a thin wire threaded through these holes. But here you need to contrive to make sure that this wire does not touch when rotating the starter cover from the inside and thus does not slow down the pulley. Alternatively, loosely tighten the screw or replace it with a similar slightly longer one. You can think of an option with the installation of some kind of gasket between the lid and the coil.
Does your power tool starter design differ from the above? Faced another malfunction, or do you know the best way to repair a starter yourself? Ask questions, share your experience with others. together we can solve the problem of frequent starter breakdowns once and for all!
How to change the starter cord?
It happens that it is not the spring that is to blame for the inability to start the starter, but the cord itself. It can seize or even break. Disassembling the starter of a lawn mower or grass trimmer is versatile in its steps.
- Remove the starter block from the grass trimmer or lawn mower.
- Remove the main bolt holding the handbrake.
- Pull out the spool and rewind the remnants of the worn out cord from it.
- Untie the knot on the cord handle and pull the end out of it.
- Untie the knot at the other end (at the beginning of the spool) and remove the old cord. Knots that have become tight are untied with pliers or pliers.
- Tie a knot at one end of the new cord, pass it through the hole at the beginning of the spool (closer to its axis).
- Wind a few turns of the new cord onto the spool. If it is long, then cut off the excess.
- Load and charge the spring-loaded cord tensioner (if removed) and spring-loaded elements in the correct sequence.
- Replace the spool and thread the free end of the cord through the starter outlet and handle.
- Reinstall the starter block.
Twist the starter by the cord, start the engine of the lawn mower or grass trimmer. The larger and more powerful the engine, the more jerks of the cord will be required at startup, the norm is no more than 7 times. The result is a quick and smooth start of the motor, the readiness of the unit for operation.
Dismantling a chainsaw
Before proceeding directly to disassembling the saw, you first need to clean it. All operations must be performed carefully and slowly. So that fasteners and small parts are not lost, containers can be used into which structural elements are folded during disassembly.
Disassembly begins by loosening the screws holding the clutch cover, after which the chain tension is released. Only after that the bolts are completely unscrewed. Then the clutch pad, tire and the chain itself are removed. In the next step, the top case cover is removed.
The stages of disassembly of the device occur in the following order:
- Removable vibration handle. It is fixed to the saw body on three shock absorbers. To remove it, you will need to remove the plugs, then, using a screwdriver, squeeze out the shock absorbers, starting from the one located farthest in relation to the handle. Then unscrew the two screws and disassemble the handle. The throttle trigger can now be removed by disconnecting the wire rod.
- The starter is removed. Removing the top cap will allow access to the oil and fuel tank plugs. After removing the plugs, the starter is removed. The place where the starter is installed is thoroughly cleaned of sawdust.
- The flywheel is released. In order to remove it from its seat, you will need to use a union head with a size 13. Initially, the candle is unscrewed, the piston is blocked through the hole formed. Having loosened the nut, a punch is installed on it, on which a sharp blow is made. From this action, the flywheel jumps off the shaft, after which it can be easily removed by hand.
- The clutch and the oil pump drive are dismantled. The drive sprocket and needle bearing are removed first. For this, the lock washer is removed. Using a size 19 head, unscrew the bolts that hold the clutch. It should be noted that the thread on it is left-handed. Having dismantled the clutch, the baffle plate and the oil supply drive are removed.
- At the penultimate stage, the carburetor with a muffler and the ignition coil are removed. In order to remove the carburetor, you will need a head 8 and an extension. Before removing the air filter and carburetor, you will need to disconnect the ignition wire and disconnect the air damper. The muffler is held by two nuts that can be easily unscrewed.
- The engine is removed. Turning the saw body over, unscrew the four screws holding the motor. Then, with a gentle movement, it is removed from the installation site.
The engine itself is easy to disassemble. First, four screws are unscrewed and the crater is removed. Next, the crankshaft is removed along with the oil seals and other elements. Removal of the piston from the connecting rod occurs after removing the retaining ring and squeezing the piston pin.
Next, the cover on the side of the STIHL 180 chainsaw is removed, and the retaining ring holding the drive sprocket is removed with a screwdriver, after which the sprocket itself is removed.
In this way, the STIHL 180 chainsaw sprocket is also replaced if necessary.
The clutch is untwisted with a 19 head and a knob. It is necessary to unscrew the clutch clockwise, since the thread is left-handed. A reflective plate is installed behind the clutch, which must also be removed. The next detail is the worm drive of the oil pump.
In the fierce winter, instead of sleeping like everyone else, my friends and I decided to build ourselves a chopper. They “dug out” two “Urals”, “Dnepr” and. forward. To bring beauty, to chrome something. not a question, but to start with a button. yes! There were three problems, and we solved them in our shed.
The first is the starter ring. It was developed and produced in Rybinsk and is installed on the Buran snowmobile. We bought it without a snowmobile. individually, attached it to the flywheel, centered and marked the holes for attaching the crown to the pillars of the driving clutch discs. They drilled out and countersunk for the bolts “in the hole”. We drill the holes of the outer drive disk to the diameter of the posts (with an allowance of 0.5 mm).
|Fig. 1. Modification of the starter ring of the Buran snowmobile: 1. crown; 2. flywheel mounting holes; 3. “Extra” part of the crown.
The second problem is the starter itself. Here the unit from the starting engine of the T-170 tractor came in handy. You can also use a starter from the “Whirlwind-30” outboard motor. brand ST-367A.
|Fig. 2. Detail of fastening of the starter (welded to the crankcase).
The third is to install a starter. First, we picked up the starter mounting bracket. In shape, it resembles a part of a bell, inside which you need to place the starter more tightly. We did not saw this part, but found a suitable one. part of the crankcase of the starting engine (therefore we do not give exact dimensions).
Then a cutout was made in the clutch housing for the starter mount, the motor was assembled for the final welding of the starter mount: a crankshaft and a flywheel with a crown are inserted into it.
Then the plug of the bendix was removed from the starter, and the bendix itself was fixed in the “on” position. The starter assembly with the fastening part was laid with the bendix gear on the flywheel crown, and “grabbed” by argon-arc welding. Rotating the flywheel, we checked the correct installation of the starter on the lateral engagement of the gears and the radial clearance between them. After adjusting the starter, the fastening part was finally scalded.
For a more reliable fixation of the starter, its rear part was compressed with a powerful clamp made of steel strip 3 mm thick. A plate is welded to the clamp, which is attached to the rear cover of the gearbox. Where necessary, we sawed down the stiffeners and fastenings of the air filter on the gearbox housing. That’s all!
So putting a starter on opposed turned out to be easier than steaming a turnip. And the measurer was not needed. The tools used were a drill, a file and a hacksaw. True, I had to take a ride to the regional center for argon, but this is not something to look for a jig boring machine.

Installing a starter on a single-axle tractor
There are various designs of starters:
The most common is a manual starter for a walk-behind tractor, since this device is very easy to put on a single-axle tractor, and it is easy to repair it yourself. If such a device is used correctly, then its durability is several years.
Consider what elements the starter for the walk-behind tractor consists of:
- a drum-shaped body;
- springs: large and small;
- fastener parts.
A reel is installed in the center of the drum, on which the cord is fixed. A large spring is located in the body around the axis and is designed to return the coil to its original position after scrolling.
The mechanism of this device is quite simple, you can assemble it yourself.
The work of a walk-behind tractor with a manual starter is carried out as follows. The driver starts the mechanism by pulling the handle of the device. In this case, the device starts to work and starts the engine. In order for the device to successfully transfer the initial rotation to the motor, the handle of the device must be pulled twice.
But despite the fact that a manual starter for a uniaxial tractor is considered a reliable device, it also sometimes fails. If the structure breaks down, you can repair it yourself.
Assembling the brushcutter starter
When servicing and repairing the starter, it is important to assemble it correctly. as if the assembly was carried out by the manufacturer. Any part that is incorrectly installed will prevent you from fully using the trimmer or brushcutter.
- After winding the spring, turn the coil over and place it so that the second spring hook falls back into place. To control the correct installation of the spring, there are technological windows on the coil itself.
- Install the starter pulley and make sure that one of the spring hooks fits into the groove located on the starter cover.
- Insert the spring and washers on the sides to prevent the spring from rubbing off the plastic compartment in which it is located. If the spring is broken, but the other is not the same, an additional washer is placed instead.
- Insert the antennae cup into the grooves of the coil.
- Install the coil in its place, tighten the bolt as far as it will go, but without fanaticism.
If you do not protect the compartment with washers from the main spring, where it moves when winding and unwinding the starter cord, the coil often gets stuck when you try to start the petrol trimmer or brushcutter. Loosening the coil bolt will result in its loss.

How does the starter for a lawn mower or grass trimmer work??
The starter is a generally single and universal mechanism for petrol cutters, trim tabs, gasoline and diesel generator sets. It is not a problem to equip them even a car, motorcycle or scooter, if your vehicle has free space for its installation. It was not for nothing that many Soviet cars and trucks were equipped with a starter tool that vaguely resembles a tire bent twice.
The modern “handbrake” starts exactly from the cord. it is tied to the mechanism, and it is impossible to lose it.
The starter assembly has the following parts:
- hook ignition spring;
- cord wound on a reel;
- return spring;
- ratchet drive and main spring;
- mechanism housing protecting the ratchet;
- locking bolt.
How to replace or replace the starter spring?
If everything is in order with the rope on the starter, suspicion falls on the reel itself. It is driven by a ribbon spring, coiled into a roll. To change the spring, certain steps must be taken.
- Remove the starter from the mower.
- Remove the starter coil.
- Unscrew the main bolt holding the pulley to the housing.
- Pull out the gripping tendrils and spring, the ribbon spring is almost fully extended or coiled into larger diameter rings.
- Hold it in advance.
- Check if the spring is intact (there may be rusty streaks, fractures, etc.). If the hooks at its ends are torn off, it will not be possible to bend new ones. high-carbon steel breaks when you try to bend it. Loose hooks are suitable for slight bending.
- Make sure the auxiliary (regular) spring and washers are in place. These parts protect the coil body from being punctured by the ends of the main spring. If the washers and spring are broken, and new ones are not available, do not tighten the coil bolt tightly, but watch it. it can unscrew and get lost.
- If the main (flat) spring is damaged, insert the same new one. Place the hook on the end of the spring in its place and bend it, inserting coil by coil into the space where it should be.
The rewinding of the spring takes a minute. Dexterity in this action is acquired quickly.

Lawn mower starters: device and installation features
The recoil starter for a lawn mower or petrol grass trimmer is a mechanical unit that includes a pulley fitted to a ratchet. A rope is wound on the pulley in the initial position. At the start, it is pulled outward. The pulley is spring loaded. as soon as you let go of the end of the rope, it will reel back. A flat tape rolled into a ring is used as a spring. It resembles a spring in a large mechanical watch that is wound once a day. The starter itself is located more often at the rear than closer to the front end of the mower or grass trimmer. In order to correctly perform all manipulations with the starter for a lawn mower, you need to know the features of the device and installation.
How tight the spring is cocking?
It is possible to give the spring the necessary potential force necessary for a clear and fast winding of the cord, by determining the length of the cord in turns. To prevent the cord handle from drooping, add 1-2 more turns to the number of turns. So, if the cord has a length of 5 turns of the coil, then when charging the spring, turn the coil 6-7 full turns.
There are times when the starter is still working, but a worn out cord can break, for example. The ratchet has not yet had time to work when the engine is started, and the remnants of the cord are immediately wound around the reel, the return spring loses its hooks, the grooves in the starter housing break. The result is the replacement of both the springs and the housing.
If the model of a lawn mower or grass trimmer has long been discontinued, it will be difficult to find exactly the same parts, and the starter is changed entirely.
How to assemble a new mower starter?
To assemble the starter, do the following manipulations.
- Pass one end of the cord through the opening at the beginning of the spool and tie it in a knot. The knot must not pass through the hole. Otherwise, you will disassemble the starter again.
- Wind the cord onto the spool itself.
- Install the spring into the starter housing, hook one end of it in the groove and wind it. For convenient winding, twist the body counterclockwise.
- Place the ratchet on the spring.
- Hook the return spring to the ratchet itself, attach it to the spool.
- Install the main spring and housing with the assembled ratchet, connect the parts of the starter together and tighten everything with the main bolt.
When you have finished assembling the starter, pass the free end of the cord through the hole in the housing for the reel. Re-pass the same end through the hole in the handle that the cord is pulling on. Tie a strong knot on the handle. Check the operation of the starter handbrake.
