Check points

• The air filter. It is often in the form of a block of foam. Dirty with sawdust dust, it must be washed; unlike paper filters that clean with compressed air.
• The exhaust outlet. Facing the exhaust ports, the silencer is held by two studs. Its removal allows to eliminate by scraping any deposits of scale.
• The launcher. If the handle does not return fully, the return spring may be "tired". Before changing it, we can try to shorten the cord.

How to remove a hard layer of resin, due to large sizes of softwood, on a hedge trimmer and chainsaw?
Christian Pessey's answer:
It exists different products of the trade bombs that clean and prevent the resin from sticking to the blade of a hedge trimmer. Do not wait until it is dirty to act.
Ideally, the blade should be cleaned and lubricated each time it is used on softwoods. If this is not the case, intervene now without waiting for the arrival of winter.
Disconnect the power supply from the machine or remove the spark plug if it is a thermal engine model. If the resin has built up and hardened, soften it by heating the blade with a heat gun. Clean the blade with a commercial product or with gasoline or oil. Lightly oil the blade and put it back in its sheath.
