Keep the deflector (and the skirt where 
appropriate) adjusted properly at all 
times (see chapter on mounting the 
various cutting tools of your owner's 
manual).
Starting
!Warning!
Your brushcutter is a one-person 
machine. Once started, it may fling 
foreign objects for a great distance.
To reduce the risk of eye and other injury 
insure that bystanders are at least 50 
feet (15 m) away. Bystanders should be 
encouraged to wear eye protection. Stop 
the engine and cutting tool immediately 
if you are approached. Start and operate 
your brushcutter without assistance. For 
specific starting instructions, see the 
appropriate section of your manual. 
Place the brushcutter on firm ground or 
other solid surface in an open area. 
Maintain a good balance and secure 
footing.
!Warning!
To reduce the risk of injury from loss of 
control, be absolutely sure that the 
cutting tool is clear of you and all other 
obstructions and objects, including the 
ground, because when the engine starts 
at starting-throttle, engine speed will be 
fast enough for the clutch to engage and 
turn the cutting tool.
!Warning!
When you pull the starter grip, don't 
wrap the starter rope around your hand. 
Do not allow the grip to snap back, but 
guide the starter rope to rewind it 
properly. Failure to follow this procedure 
may result in injury to hand or fingers 
and may damage the starter 
mechanism.
With the engine running but at idle, 
attach the brushcutter to the spring hook 
of your harness (see appropriate 
chapter of this manual).
Catalytic converter
!Warning!
Some STIHL brushcutter 
models are equipped with 
a catalytic converter, 
which is designed to 
reduce the exhaust 
emissions of the engine 
by a chemical process in the muffler. 
Due to this process, the muffler does not 
cool down as rapidly as conventional 
mufflers when the engine returns to idle 
or is shut off. To reduce the risk of fire 
and burn injuries, the following specific 
safety precautions must be observed.
!Warning!
Since a muffler with a catalytic converter 
cools down less rapidly than conven-
tional mufflers, always set your 
brushcutter down in the upright position 
and never locate it where the muffler is 
near dry brush, grass, wood chips or 
other combustible materials while it is 
still hot.
