•
Loosen the bolts holding the spring cassette.
•
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.
Bear in mind that the return spring lies tensioned in the
starter housing. If the spring flies out during assembly, it is
wound working from the outside towards the centre.
•
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.
•
Fit and tighten the screws that hold the starter.
Spark plug
The spark plug condition is influenced by:
•
Incorrect carburettor adjustment.
•
Wrong fuel mixture (too much oil).
•
A dirty air filter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.
MAINTENANCE
•
If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
before taking any further action. If the spark plug is dirty,
clean it and check that the electrode gap is 0.5 mm. The
spark plug should be replaced after about a month in
operation or earlier if necessary.
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:
1 Air intake on the starter.
2 Air guide plate.
3 Fins on the flywheel.
4 Cooling fins on the cylinder.
5 Cylinder 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.
