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.

WARNING
To reduce the risk of injury from parts
thrown by the fan wheel, check the fan
housing for damage (cracks or holes
that could allow foreign objects to
contact the fan wheel). If any such
damage is found, stop using the unit and
contact your STIHL dealer for repair.
WARNING
Adjust carrying harness to suit your size
before starting work.
In an emergency, you may slip out of the
harness and throw off the machine
quickly. Try slipping out of the harness a
number of times before using the
machine in order to become
accustomed to it. Do not throw off the
machine while practicing as it could
damage the machine.
Starting
To reduce the risk of fire and burn
injuries, start the engine at least 10 feet
(3 m) from the fueling spot, outdoors
only.
WARNING
Your power tool is a one-person
machine. To reduce the risk of eye or
other injury from thrown objects, insure
that bystanders are at least 50 feet
(15 m) away during use. Stop operation
immediately if you are approached.
WARNING
This unit is equipped with an ignition
system that is normally in operational
readiness. After the setting lever is used
to stop the engine, it automatically
springs back to the "on" position. If the
engine is warm, it may be possible to
start it by simply pulling the starter rope,
with no further adjustments. To reduce
the risk of injury, be particularly alert to
keep children away from the unit.
For specific starting instructions, see the
appropriate section of your manual.
Place the power tool on firm ground or
other solid surface in an open area.
Maintain good balance and secure
footing.
WARNING
When you pull the starter grip, do not
wrap the starter rope around your hand.
Do not let the grip snap back, but guide
the starter rope to rewind it properly.
Failure to follow this procedure may
result in injury to your hand or fingers
and may damage the starter
mechanism.
Once the engine has started,
immediately blip the throttle trigger,
which should cause the choke knob to
move to the run position and allow the
engine to slow down to idle.
