FUEL HANDLING
The oil pump
The chain is lubricated by an
automatic oil pump. The pump
does not normally require any
maintenance, provided that
clean chain oil (of special
type) is used, and that no dirt
is allowed to get into the tank
during filling.
The flow of oil to the chain can
be regulated by means of an
adjuster screw as indicated in
the illustration above, using a
screwdriver or combination
key. For maximum flow, turn
the screw in a clockwise
direction as far as it will go.
The oil pump is adjusted at
the factory to supply a normal
flow of oil to the chain. The
settings should be such that
the saw's fuel and oil tanks run
dry at the same time.

Fuelling
Taking the following precautions, will lessen
the risk of fire.
• Do not smoke or place warm objects in the vicinity of
the fuel.
• Always shut off the engine before refuelling.
• Slowly open the fuel cap, when filling fuel, so that
possible overpressure is slowly released.
• Tighten the fuel cap carefully after fuelling.
• Always move the saw from the fuelling area before
starting.
Clean around the fuel cap.
Clean the fuel and chain oil
tanks regularly. The fuel filter
should be changed at least
once a year. Contamination in
the fuel tanks causes
malfunction. Make sure the
fuel is well mixed by shaking
the container before fuelling.
The volume of chain oil and
fuel tanks are adjusted to
each other. Therefore, always
fill chain oil and fuel at the
same time.
