WARNING
Before Starting
WARNING
Always check your power tool for proper 
condition and operation before starting, 
particularly the throttle trigger, setting 
lever and momentary 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.
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.
