English
To return the cap to the open
N
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
N
properly, it may be damaged or
broken; immediately stop use of the
unit and take it to your authorized
STIHL dealer for repair.
Screw Cap
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
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!
Never operate your power tool if it is
damaged, improperly adjusted or main-
tained, 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.
On metal tools (top illustration), position
the gearbox so that the shaft is below
the drive tube.
