– Never remove the cap by turning it
directly to the open position. Turn it
first approximately 1/2 of a turn
counter-clockwise to relieve any
residual pressure.
– Never open the fuel tank while the
engine is still hot or running.
– Never open the fuel tank or re-fuel
the saw near any sparks, flames or
other ignition sources.
– Pick the right fuel: use only good
quality (89 octane or higher), fresh
fuel blended for the season.
– Vapor lock: do not remove the fuel
cap in an effort to relieve vapor lock.
Removing the cap has no effect on
vapor lock.
– Be aware that fuel spraying is more
likely at higher altitudes.
Preparations
N Before fueling, clean the filler cap
and the area around it to ensure that
no dirt falls into the tank.
N Position the machine so that the
filler cap is facing up.
WARNING
In order to reduce the risk of fire and
other personal injury from escaping gas
vapor and fumes, remove the fuel filler
cap slowly and carefully so as to allow
any pressure build-up in the tank to
release slowly
Opening
WARNING
After allowing the chain saw to cool,
remove the fuel filler cap slowly and
carefully to allow any remaining
pressure build-up in the tank to release:
N While maintaining steady,
downward pressure, slowly turn the
cap approximately a 1/2 turn
counter-clockwise.
N If any significant venting occurs,
immediately re-seal the tank by
turning the cap clockwise to the
closed position. Allow the saw to
cool further before attempting to
open the tank.
N Turn the cap to the open position
only after the contents of the tank
are no longer under pressure.
N Remove the fuel filler cap.
WARNING
Never remove the cap by turning it
directly to the open position. First allow
the saw to cool adequately and then
release any residual pressure by slowly
turning the cap approximately 1/2 turn
counter-clockwise. Never attempt to
remove the cap while the engine is still
hot or running.
Refueling
Take care not to spill fuel while fueling
and do not overfill the tank – leave
approximately 1/2" (13 mm) air space.
