Repeated and/or substantial inhalation 
of airborne crystalline silica can cause 
serious or fatal respiratory diseases, 
including silicosis. In addition, California 
and some other authorities have listed 
respirable crystalline silica as a 
substance known to cause cancer. 
When cutting such materials, always 
follow the respiratory precautions 
mentioned above.
WARNING
Breathing asbestos dust is dangerous 
and can cause severe or fatal injury, 
respiratory illness or cancer. The use 
and disposal of asbestos-containing 
products have been strictly regulated by 
OSHA and the Environmental Protection 
Agency. Do not use your cut-off machine 
to cut or disturb asbestos, asbestos-
containing products, or products such as 
pipes which are wrapped or covered 
with asbestos insulation. If you have any 
reason to believe that you might be 
cutting asbestos, immediately contact 
your employer or a local OSHA 
representative.
WARNING
Your STIHL cut-off machine is designed 
for hand-held use or operation on a cut-
off machine cart. Cutting with your cut-
off machine resting on the ground or 
other surface can cause excessive wear 
to the bracket designed to protect the 
bottom of the tank housing. Loss of fuel 
and personal injury from fire may result. 
Replace damaged or badly worn 
brackets immediately.
Grip: Never use the cut-off machine with 
one hand. Always hold the cut-off 
machine firmly with both hands when the 
engine is running. Place your left hand 
on front handle bar and your right hand 
on rear handle and throttle trigger. Left-
handed users should follow this 
instruction too.
Wrap your fingers tightly around the 
handles, keeping the handles cradled 
between your thumbs and forefingers. 
Make sure your cut-off machine handles 
and grip are in good condition and free 
of moisture, pitch, oil, fuel mix or grease.
Never touch a rotating wheel with your 
hand or any part of your body.
WARNING
Clear the area where you are working. 
Avoid stumbling on obstacles and watch 
out for holes or ditches. Be extremely 
cautious when working on slopes or 
uneven ground. Take extreme care in 
wet and freezing weather (rain, snow, 
ice.)
WARNING
Never operate the cut-off machine with 
the starting-throttle lock engaged as this 
does not permit proper control of the 
speed of the unit and may lead to 
serious injury.

WARNING
To reduce the risk of injury from fire, do 
not cut into any pipe, drum or other 
container without first ensuring that it 
does not contain a volatile or flammable 
substance.
