!Warning!
Before cutting, inspect the 
area for stones, glass, 
pieces of metal, trash or 
other solid objects. The 
cutting attachment could 
throw objects of this kind.
!Warning!
When using rigid blades, avoid cutting 
close to fences, sides of buildings, tree 
trunks, stones or other such objects that 
could cause the clearing saw to kick out 
or could cause damage to the blade. 
STIHL recommends use of the nylon line 
heads or PolyCut head for such jobs. In 
addition, be alert to an increased 
possibility of ricochets in such situations.
!Warning!
This clearing saw is normally to be used 
at ground level with the cutting attach-
ment parallel to the ground. Use of a 
clearing saw above ground level or with 
the cutting attachment perpendicular to 
the ground may increase the risk of 
injury, since the cutting attachment is 
more fully exposed and the clearing saw 
may be more difficult to control. Never 
use your clearing saw as a hedge 
trimmer.
Do not operate using the starting throttle 
lock as you do not have control of the 
engine speed. See section of your 
owner's manual on the proper use of the 
slide control.
If the cutting tool or deflector becomes 
clogged or stuck, always turn off the 
engine and make sure the cutting tool 
has stopped before cleaning. Grass, 
weeds, etc. should be cleaned off the 
cutting tool at regular intervals.
!Warning!
During cutting, check the tightness and 
the condition of the cutting tool at regular 
intervals. If the behavior of the tool 
changes, stop the engine immediately, 
and check the nut securing the tool for 
tightness and the cutting tool for cracks 
and damage. Replace cracked, bent, 
warped, damaged or dull cutting tools 
immediately. Such tools may shatter at 
high speed and cause serious or fatal 
injury.
!Warning!
A loose blade may cause the blade to 
vibrate, crack, break or come off the 
clearing saw, which may result in serious 
or fatal injury. Make sure that the blade 
is properly tightened. Use the wrench 
supplied or one of sufficient length to 
obtain the proper torque. If the blade 
loosens after being properly tightened, 
stop work immediately. The retaining nut 
may be worn or damaged and should be 
replaced. Never use unauthorized parts 
to secure the blade. If the blade 
continues to loosen, see your STIHL 
dealer. Never use a clearing saw with a 
loose blade.
Do not attach any blade to a unit without 
proper installation of all required parts. 
Never use unauthorized parts to secure 
the blade. Failure to use the proper parts 
may cause the blade to fly off and 
seriously injure the operator or 
bystanders.
