Opening
WARNING
After allowing the power tool 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 power
tool 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 power tool 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.
Closing
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, tighten the fuel filler
cap by hand with as much force as
possible:
N If your fuel cap still does not tighten
properly, it may be damaged or
broken. Stop using the power tool
and take it to your authorized STIHL
dealer for repair or replacement.
Change the fuel pickup body
Change the fuel pickup body every year.
N Open the filler cap and drain the fuel
tank.
N Use a hook to pull the fuel pickup
body out of the tank and take it off
the hose.
NOTICE
Do not kink the fuel hose – do not use
any sharp or pointed tools.
N Push the new pickup body into the
hose.
N Place the pickup body in the tank
and close the filler cap.
