MAINTENANCE
•Remove the recoil spring by turning the starter over and loosen the hooks, with the help of a screwdriver. The hooks hold the return spring assembly on the starter.
•Lubricate the recoil spring with light oil. Fit the pulley and tension the recoil spring.
Fitting the starter
•To fit the starter, first pull out the starter cord and place the starter in position against the crankcase. Then slowly release the starter cord so that the pulley engages with the pawls.
•Tighten the screws.
Spark plug
The spark plug condition is influenced by:
•Wrong fuel mixture (too much oil).
•Dirty filters.
These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties.
•If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking other steps. If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm.
CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder.
Cooling system
To keep the working temperature as low as possible the machine is equipped with a cooling system.
The cooling system consists of:
5
4
3
2
1
1Air intake on the starter.
2Air guide plate.
3Fins on the flywheel.
4Cooling fins on the cylinder.
5Cylinder cover
Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.
Muffler
The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material.
Never use a machine with a defective muffler.
