Cleaning and checking
WARNING!
The fuel used for the chain saw
has the following hazardous
properties:
1. The liquid and its fumes are
poisonous.
2. Can cause skin irritation.
3. Is very flammable.
Clean all units in clean petrol.
WARNING!
Never direct the compressed
air jet towards the body. Air
can penetrate into the blood
circulation, which means mortal
danger.
Use compressed air to dry the petrol on the
components. Direct the air through all channels in
the carburettor housing and ensure that they are
not blocked. Check the following:
1. That the gasket, pump and control diaphragms
are undamaged, as well as the gasket between
the carburettor body and the autotuner.
2. That there is no play on the throttle valve and
choke valve shafts.
3. That the needle valve (J) and its lever arm (G)
are not worn. See Figure 42.
4. That the fuel screen is intact and clean.
5. That the inlet manifold is undamaged.
