!Warning!
To reduce the risk of fire or burn injury, 
keep the area around the muffler clean. 
Remove all debris such as pine needles, 
branches or leaves.
!Warning!
An improperly mounted or damaged 
cylinder housing or a damaged/
deformed muffler shell may interfere 
with the cooling effect of the catalytic 
converter. To reduce the risk of fire or 
burn injury, do not continue work with a 
damaged or improperly mounted 
cylinder housing or a damaged/
deformed muffler shell. Your catalytic 
converter is furnished with screens 
designed to reduce the risk of fire from 
the emission of hot particles. Due to the 
heat from the catalytic reaction, these 
screens will normally stay clean and 
need no service or maintenance. If you 
experience loss of performance and you 
suspect a clogged screen, have your 
muffler maintained by a STIHL Servicing 
Dealer.
Working Conditions
Operate the chainsaw under good 
visibility and daylight conditions only.
!Warning!
Your chainsaw produces 
poisonous exhaust fumes 
as soon as the 
combustible engine is 
running. These gases 
(e.g. carbon monoxide) 
may be colorless and odorless. To 
reduce the risk of serious or fatal injury 
from breathing toxic fumes, never run 
the chainsaw indoors or in poorly 
ventilated locations. Ensure proper 
ventilation when working in trenches or 
other confined areas.
!Warning!
Use of this product (including sharpen-
ing the saw chain) can generate dust, 
mists and fumes containing chemicals 
known to cause respiratory disease, 
cancer, birth defects, or other 
reproductive harm. If you are unfamiliar 
with the risks associated with the 
particular dust, mist or fume at issue, 
consult your employer, governmental 
agencies such as OSHA and NIOSH 
and other sources on hazardous 
materials. California and some other 
authorities, for instance, have published 
lists of substances known to cause 
cancer, reproductive toxicity, etc. Control 
dust (such as sawdust), mists (such as 
oil mist from chain lubrication) and 
fumes at the source where possible.
In this regard use good work practices 
and follow the recommendations of 
OSHA / NIOSH and occupational and 
trade associations. When the inhalation 
of toxic dust, mists and fumes cannot be 
eliminated, the operator and any 
bystanders should always wear a 
respirator approved by NIOSH / MSHA 
for the type substance at issue.
!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 cut or disturb asbestos, 
asbestos containing products (e.g. 
asbestos containing drywall or other 
construction 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.
