N 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.
N 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
See also the "Fueling" chapter in your
Instruction Manual for additional
information.
Before Starting
Before starting work, open up the bike
handle and lock it in position with the
rotary knob. See chapter on "Adjusting
the Bike Handle."
WARNING
Always check your power tool for proper
condition and operation before starting,
particularly the throttle trigger, starting
throttle lock, slide control / stop switch,
working tool and deflector. 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.
Inspect for loose parts (nuts, screws,
etc.) and for cracked, bent, warped or
damaged working tools.
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.
WARNING
To reduce the risk of injury from a
MultiTool rotating in the wrong direction,
check that the position of the gearbox is
correct and change it if necessary.

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.
