To relieve vapor lock:
–
Place the Choke Knob in the cold
start position
g
and pull the starter
cord approximately 20 times to clear
the vapor and send liquid fuel into
the carburetor.
–
To start the power tool, move the
Choke Knob to the starting throttle
position
<
and pull the starter cord
approximately 10 times.
–
If your power tool will not restart, or
if vapor lock occurs again, the
power tool is being used in
conditions too extreme for the fuel
being used. Discontinue use and let
the engine cool completely before
attempting to start the power tool.
Before Operation
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 power tool repaired by a STIHL
servicing dealer before using it.
WARNING
Never operate your power tool if it is
damaged, improperly adjusted or
maintained, or not completely and
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.
