Fold the grip flush with
the top of the cap. Grip
the cap and check for
tightness. If the grip does
not lie completely flush
with the cap and the
detent on the grip does
not fit in the correspond-
ing recess in the filler
opening, or if the cap is
loose in the filler opening,
the cap is not properly
seated and tightened and
you must repeat the
above steps.
Misaligned, damaged or broken cap
If the cap does not drop fully into the
opening when the positioning marks line
up and/or if the cap does not tighten
properly when twisted, the base of the
cap may be prematurely rotated (in
relation to the top) to the closed position.
Such misalignment can result from
handling, cleaning or an improper
attempt at tightening.
Left: Base of cap in closed posi-
tion (with open space)
Right: Base of cap correctly posi-
tioned for installation

To return the cap to the open position for
installation, turn the cap (with the grip
up) until it drops fully into the tank
opening. Next, twist the cap
counterclockwise as far as it will go
(approx. 1/4 turn) – this will twist the
base of the cap into the correct position.
Then, twist the cap clockwise, closing it
normally.
If your cap still does not tighten properly,
it may be damaged or broken;
immediately stop use of the unit and
take it to your authorized STIHL dealer
for repair.

WARNING
Unit vibrations can cause
an improperly tightened
fuel filler cap to loosen or
come off and spill quanti-
ties of fuel. In order to
reduce the risk of fuel
spillage and fire, tighten
the fuel filler cap by hand
as securely as possible.
See also the "Fueling" chapter in your
Instruction Manual for additional
information.
Before Starting
WARNING
Always check your power tool for proper
condition and operation before starting,
particularly the throttle trigger, setting
lever and stop switch. The throttle trigger
must move freely and always spring
back to the idle position. Never attempt
to modify the controls or safety devices.
WARNING
Check fuel system for leaks, especially
the visible parts, e.g., filler cap, hose
connections, manual fuel pump (only for
power tools equipped with a manual fuel
pump). Do not start the engine if there
are leaks or damage – risk of fire! Have
the machine repaired by a servicing
dealer before using it.
WARNING
Never operate your power tool if it is
damaged, improperly adjusted or
maintained, or not completely or
securely assembled.
WARNING
Check that the spark plug boot is
securely mounted on the spark plug – a
loose boot may cause arcing that could
ignite combustible fumes and cause a
fire.
Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, fuel mix,
grease or resin in order for you to
maintain a firm grip and properly control
your power tool.
