escaping gasoline, vapors or fumes can
cause serious personal injury, including
fire and burn injury, or property damage.
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.
Installing the Toolless Fuel Cap
WARNING
An improperly tightened fuel filler cap
can loosen or come off and spill
quantities of fuel. To reduce the risk of
fuel spillage and fire from an improperly
installed fuel cap, correctly position and
tighten the cap in the fuel tank opening:
– 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urn). 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.
Misaligned, Damaged or Broken Cap
WARNING
If the cap does not drop fully into the fuel
tank opening when the positioning
marks (1, 2) line up, or if it does not
tighten properly when turned, the base
of the cap may be prematurely rotated in
relation to the top. Such misalignment
can result from handling, cleaning or an
improper attempt at tightening.
– Illustrations A and B: The base of
the cap is prematurely rotated to the
closed position and is not in the
correct starting position for
installation. The tank will not seal in
this configuration. Note: in
IllustrationsA andB, the interior
positioning marks(1) are in line with
the exterior position marks(2).
– Illustration C: The bottom of the cap
is in the correct starting position for
installation. Note: In IllustrationC,
the interior positioning mark(1) is
under the grip and not in line with
the outer position mark(2).
To return the base of the cap to the
proper starting position for installation:
