The most difficult starter failure occurs when a rope breaks and winds it around the flywheel of a running engine. As a result, the spring can burst and the pulley break. In this case, only a complete replacement of the spare part will help. Such a breakdown is rare. often it happens:

  • Shmorgalka rope break;
  • Spring breakage;
  • Loose spring engagement.

In this case, it is easy to repair the starter yourself. The manufacturer has prepared step-by-step instructions for this.

Magneto. Construction and operating principle

The purpose of the ignition coil. Converting rotational energy into a high-voltage discharge and forming a spark that ignites the fuel mixture. In an internal combustion engine, this part is called a magneto, since in it an alternating current is generated from the rotation of a permanent magnetic rotor or armature.

Magneto structurally consists of two windings: high and low voltage. A capacitor with breaker contacts is connected in parallel to the latter. Whereas the leads of the high voltage winding are connected to the candle and the body. Both of them are wound on a core, between the poles of which a rotating magnet is installed, magnetized longitudinally.

On a note! The whole structure looks like a large coil mounted on a U-shaped core.

  • 2-stroke engines do not have their own lubrication system, therefore they work not in pure gasoline, but on a mixture of gasoline and oil. The latter, getting into the combustion chamber, lubricates the moving engine components.
  • 4-stroke engines are lubricated with oil in the crankcase. They run on pure gasoline without impurities.

How to disassemble the philips trimmer. Step 2 Replacing the battery

Take note of the pularity of the battery (red arrows)

The plastic casing around the battery (blue arrow) can be easily removed. Battery slides out of it

Battery can be de-suldered. Just remember which culor wire goes where. In this case, black for negative (-) and white for positive.

Replace the battery and re-sulder the joints

Use a brush to clean the inside of your trimmer before re-assembling it. After so many years of service, hairs have surely gotten inside of it.

To re-assemble the trimmer carefully place the top part over the bottom one (make sure no wires get in the way) and press down until the to parts snap into place. You’ll have to use a bit of force. Also, make sure the charging port at the back is placed properly.

In the end there will be some marks left on the plastic even if you used plastic cards to help protect the case but nothing as bad as using metal touls for the job. I do not believe that Philips intended for this to be repairable.

On choosing the right rechargeable replacement:

I went with a 800mAh NiMh. Sure, without the plastic casing around the battery you could fit an AA size rechargeable in there. However, keep in mind that while a bigger battery will huld a charge for a longer time (more trimming sessions) but it will also take a lot longer for your included charger to actually charge it.

Philips says that their original battery takes

10h to fully recharge. The 800mAh will take roughly 16h.

If prevention hasn’t helped

What to do if the petrol trimmer still breaks down? DIY repair. Not a bad option! Let’s make a reservation right away that we will talk more about engine malfunctions, since almost everyone can fix a broken rod. In extreme cases, you can simply secure it with some kind of tire and clamps.

What not to do

It is known that prophylaxis is much preferable to treatment, and then do not forget to take care of the instrument so that it does NOT need repairs.

How To Disassemble A Petrol Trimmer

Ignition

Is the candle wet? Completely abandoned gasoline-oil mixture? Your petrol trimmer we are trying to repair has carburetor adjustment problems. This often happens when non-specialists have tried to tune it. If you have no experience, we strongly advise you to contact the service center, since by your actions you may well burn the entire piston system.

However, not everything is so bad: if you are breaking the rules of cold start, all the time trying to pump the fuel mixture, then this can easily lead to throwing.

It is a different matter when the candle is covered with a thick layer of black carbon. In this case, the gasoline trimmer, the repair of which we describe, has been exposed to a poor-quality fuel mixture. Maybe the point is again in the incorrect adjustment of the carburetor, which gives out a too saturated fuel mixture. Just replace the candle.

Often, the lack of gasoline entering the combustion chamber is explained by the fact that a lot of dirt has accumulated in the gas tank, which simply clogged the supply hose. Disconnect the fuel hose. If fuel does NOT flow from it, then a clogged fuel filter or breather is to blame. The latter can be cleaned with a needle, while the former should be completely changed every three months.

Among other things, repair of petrol trimmers Patriot often requires replacement of the air filter. When clogged, it prevents the formation of a normally rich fuel mixture.

And one more thing: often a muffler clogged with carbon deposits is to blame for everything. It must be dismantled, washed in kerosene or burned on a burner. This is especially often done by someone for whom the repair of gasoline trimmers Husqvarna is a daily job.
