How to Repair a Manual Starter
Recently, many consumers have begun to give preference to electric starter gears. Such a device is much easier to use, it is more convenient to start and even an inexperienced user can operate. But do not forget that if the battery is broken or refuses to work, you just can not start the equipment with the electric starter. For this reason, manual starting is considered more reliable, the more so if you work with the unit far from the city, it is better to take this element with you to continue working.
How to repair a manual generator starter yourself should know every user
The starter is one of the most important parts of any device, because without it it will not work. But, unfortunately, it often breaks and leads to problems with starting the engine. Therefore, if possible, stock up on an additional manual ignition, which can be installed in place of the faulty part.
Starter breakdowns and how to fix them
If a chainsaw is started often, it will lead to an accelerated depletion of the starter motor. It is impossible to predict which part of the starter will fail first, but more often the cable breaks or the spring. The cable breakage is easy to identify, but in any case, if there is a breakage, you will need to revise and repair chain saw starters.
Common breakdowns of the starting mechanism of units and their elimination:
- Cord breakage and replacement. As soon as the motor is started, the cable comes into contact with the body of the mechanism in the form of friction, thus there is its rubbing. If the cable has obvious signs of wear, it is better not to wait until the handle is torn off at all, and you can start the chainsaw only after repair. The starter rope must be replaced, for which the body is disassembled, and the ratchet mechanism is lifted. Lift it carefully to prevent the return spring from coming off. The old cable is disconnected, and a new starter cord is installed in its place. After replacement, the cover is reinstalled
- Replacing the starter springs for chain saws. Now let’s consider how to replace the starter spring of the gasoline-generator. a device that returns the drum together with the cable to its original position. If the spring in the place of connection to the drum (where the loop is formed) is damaged, then changing it for a new one is not necessary at all. This can be done by making a new hinge, having previously cleaned the place of damage. After that, the spring is heated to 600-650 degrees (when it turns crimson), and gradually cooled. At a temperature of 150 degrees, make a bend, and completely cool the part. You can now reassemble it and start using it again. If there is difficulty heating or the spring breaks elsewhere, then it should be replaced
- Repair and replacement of the handwheel dogs with their own hands is not particularly difficult. The work starts with the removal of the handwheel and the dogs. New ones made of the same materials should be installed in place of the removed dogs. If instead of plastic, you decide to put a metal, then they can, and will last longer, but faster wear the flywheel. How to replace the chainsaw handwheel paddles is explained in detail in the video.
The working model has a rope guide bar. It is located in the grass trimmer engine and its gearbox, which makes the working rotary cutting tool move at startup. The top of the lawnmower is equipped with a carburetor with an electric starter, and the bottom of the device is placed a gearbox with a working tool with a filter. The trimmer has a sturdy handle to control the unit. A hand strap is included with the lawnmower to keep the mower boom free.
It is better to buy a grass trimmer on a two-stroke executive engine. So the repair of the lawnmower with their own hands on the basis of a two-stroke starter is much easier to make. Working two-stroke starters for brushcutters are easy to set up compared to four-stroke engines.
There may be malfunctions in the operation of the lawnmower:
- the brushcutter engine won’t start;
- the cutting device of the grass trimmer does not make revolutions;
- When starting the engine or the electric starter of the lawnmower stalls;
- The mower’s executive gearbox overheats;
- The handle of the unit and the working piston of the brushcutter strongly vibrates.
To adjust lawn mower malfunctions, there is a device diagnostics. It is necessary to check the working area of the unit, highlighting the nonworking elements of the grass trimmer.
Lubricating the working tool and etching the filter helps. Taking care of a chain saw will extend the life of the lawnmower. In order to lubricate the grass trimmer, you need to tighten the fasteners, prepare fuel mixes and fill the fuel tank.
The engine does not start
When the lawn mower actuator does not start at startup, you need to check:
- whether there is enough fuel mixture in the fuel tank of the trimmer;
- the operation of the spark plugs in the actuator;
- The freshness of the fuel filters;
- Clean fuel valve for exchanging air and rpm engine.
Thus, you can fill the working lawnmower with a fuel mixture of AI-92. It is better to fill the fuel mixture for ignition with a syringe.
To check the lawnmower spark plugs and troubleshoot them, you need to spark. The spark plugs work by rubbing against the brushcutter. If you were able to check this, then the breakdown of the brushcutter will fix the candle channel drying. Grass trimmer spark plugs are also good for drying out. If you replace the spark plug without drying the channel, the lawnmower’s failure will worsen.
When the breakdown occurs in the ignition device, you will need a professional to repair the grass trimmer. With your own hands to make the adjustment or adjustment of this mower malfunction is impossible.
If the air regulating filter is removed and the brushcutter motor is not stalled, it is important to replace and etch the fuel filter. Replace the lawn trimmer fuel filter with care. Check the freshness of the air valve and disassemble the grass trimmer’s revolving channel.
When repairing the lawnmower carburetor it must be disassembled into parts. To check the carburetor breakage invite a specialist. The carburetor parts aren’t very durable, and it won’t be easy to disassemble the carburetor.

Gearbox Repair and Lubrication
Gearboxes in a chainsaw are responsible for transferring the rotational impulse to the engine and to the cutting unit of the tool. The starter motor is designed with fewer revolutions on the lower cutting wheel than on the lawnmower engine.
Repairing the lawnmower begins with pickling the toothed gears. Operating gear needs to be lubricated once a season.
First clean the plug of the gearbox hole and unscrew it with a tool according to the diagram. The electric chainsaw is laid on its side, opening up the lubrication. Slowly turning the blades, putting grease in the area of the body of the device. As the pinion rotates, the mixture is distributed over the teeth.
When the gearbox is overheated in a breakdown, it is repaired by replacing the bearings. A lawn mower unit with a riding piston needs a replacement body, which must be screwed onto the tube.
When repairs require replacement of the gearbox, a new unit is picked up that:

Chainsaw starter device
Almost all major chainsaw manufacturers supply their products with a starter motor that works the same way. It is no coincidence that specialized stores offer universal designs of starters, which are equally successful for chain saws STIHL, Husqvarna, Makita, and the Chinese semi-official imitations of the named brands. Only chainsaw starters of domestic production (Lesnik, Ural and some others) have some features.
The principle of the chain saw starter is as follows. The electric brushcutter is fitted with a handle in the housing groove, through which a wire is fed. If the handle is lifted sharply, the cable is pulled and engages the ratchet mechanism drum, which transmits the movement to the drum with splines provided on the shaft.
The rotating crankshaft completes several revolutions, compressing the fuel-air mixture between the piston and the cylinder head. Accordingly, when the handle is lowered, the contact between the ratchet and the splines is lost, and the shaft stops.
As the engine volume increases, so does the amount of fuel-air mixture required for its subsequent ignition, so the number of jerks for the starter rope for high-powered saws increases. Therefore, in order to accelerate the return of the drum are used involuntary return springs, made of steel with high elastic properties.
Making it easier to start the chainsaw is realized in the following ways:
- Pre-enrichment of the working mixture, for which the carburetor design has a special flap.
- Installation of an automatic decompression valve, which provides a reduction in the working pressure in the cylinder of the chainsaw.
- The installation of an additional spring, which facilitates the unwinding of the crankshaft while moving the cable.
- Certain chainsaws (e.g. Partner S-series, Maxcut etc.) are equipped with a rotary starter motor.) primer is a pump that provides pre-pumping of the fuel.
Grass trimmer starter: breakdowns, selection, replacement and operation
The manual starter serves to start the engine of the grass trimmer, and in case of its failure, the operation of the tool becomes impossible.

It is best not to experiment or skimp on spare parts for your brushcutter. You will only need a screwdriver with a suitable tip. You do not need any special knowledge and skills. It is enough to navigate the design, remember the sequence of disconnection of the starter to properly install the new.
Starter. the mechanism is largely uniform and universal for chain saws, trimmers, gasoline and diesel generator sets. Even a car, motorcycle or scooter is no problem to equip it if your vehicle has the space to fit it. Not for nothing many Soviet cars and trucks were equipped with a starter tool, remotely resembling a bent double tire iron.
Modern “handbrake” starts exactly from the cord. the cord is tied to the mechanism, and it is impossible to lose.
The starter assembly has the following parts:
- hooked ignition spring;
- The cord wound on the spool;
- return spring;
- Drive ratchet and main spring;
- The mechanism housing that protects the ratchet;

What to do if the chain saw starter cord breaks?
The lanyard may break where it attaches to the trigger coil or handle. Breakage in the middle is extremely unlikely, as manufacturers use very strong and hard-wearing kapron ropes for their products. Such material can be sold in whole coils, but given the short length, it is wise to buy a starter cord from a sport or hardware store.
For the replacement it is enough to buy 1-2 linear meters of thin kapron wire, and in a little time to make the simplest repair with your own hands. This will not only save you money, but also a lot of time compared to going to a repair shop. If you have all necessary parts at hand you will have a good chain saw in 20 minutes.
