Important Adjustments
If you cannot set the correct idle speed, 
have your STIHL dealer check your 
power tool and make proper 
adjustments and repairs.
During Operation
Holding and Controlling the Power 
Tool
Always hold the unit firmly with both 
hands on the handles while you are 
working. Wrap your fingers and thumbs 
around the handles.
Working Conditions
Operate and start your power tool only 
outdoors in a well-ventilated area. 
Operate it under good visibility and 
daylight conditions only. Work carefully.
Warning!
Your power tool is a one-person 
machine. Do not allow other persons in 
the general work area, even when 
starting.
Warning!
To reduce the risk of injury from loss of 
control, do not attempt to "drop start" 
your power tool.
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.
Warning!
To reduce the risk of personal injury 
from loss of control or contact with the 
running cutting attachment, do not use 
your unit with incorrect idle adjustment. 
At correct idle speed, the cutting attach-
ment should not move. For directions on 
how to adjust idle speed, see the appro-
priate section of your instruction 
manual.
Warning!
Never attempt to operate 
your power tool with one 
hand. Loss of control of 
the power tool resulting in 
serious or fatal injury may 
result. To reduce the risk 
of cut injuries, keep hands and feet 
away from the cutting attachment. 
Never touch a moving cutting attach-
ment with your hand or any other part of 
your body.

Warning!
Do not overreach. Keep proper footing 
and balance at all times. Special care 
must be taken in slippery conditions 
(wet ground, snow) and in difficult, over-
grown terrain. Watch for hidden 
obstacles such as tree stumps, roots 
and ditches to avoid stumbling. For bet-
ter footing, clear away scrub and 
cuttings. Be extremely cautious when 
working on slopes or uneven ground.
Warning!
To reduce the risk of injury from loss of 
control, never work on a ladder or on 
any other insecure support. Never hold 
the cutting attachment above waist 
height.
