5 IMPORTANT SAFETY INSTRUCTIONS
Removing the Toolless Fuel Cap: Turn Slowly and Stop in
the Vent Position
WARNING
￭
1 2
￭ 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:
– Flip up the grip and press the cap down firmly (1).
– While maintaining steady, downward pressure, turn
the cap slowly counter-clockwise to the vent
position (2), approximately a 1/8 turn of the cap.
– 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.
– Turn the cap to the open position (3) only after the
contents of the tank are no longer under pressure. In
the open position, the exterior positioning mark (4)
on the cap will line up with the "unlocked" symbol (5)
on the fuel tank housing.
– Never remove the cap by turning it directly to the
open position without first allowing the saw to cool
adequately and then letting it release any residual
pressure at the vent position (2).
– Never attempt to remove the cap while the engine is
still hot or running.

– Raise the grip on the top of the cap until it is upright
at a 90° angle. Insert the cap in the fuel tank opening
with the exterior positioning mark (1) lined up with
the "unlocked" symbol (2) on the fuel tank housing.
– Using the grip, press the cap down firmly while
turning it clockwise to the closed position
(approximately 1/4 turn). In the closed position, the
interior (4) and exterior (1) positioning marks will
align with the "locked" symbol (3) on the fuel tank
housing.
– Fold the grip flush with the top of the cap and check
for tightness.
– If the grip does not lie completely flush with the cap
or the detent on the grip does not fit in the
corresponding recess in the tank opening, or if the
cap is loose, the cap is not properly seated and you
must repeat the above steps. Refer to the procedure
below for returning the base of the cap to the proper
starting position for installation.
