To reduce this risk, always engage the 
chain brake before starting. Never 
attempt to start the chainsaw when the 
guide bar is in a cut or kerf. When you 
pull the starter grip, do not wrap the 
starting rope around your hands. Do not 
allow the grip to snap back, but guide the 
starter rope slowly back to permit the 
rope to rewind properly. Failure to follow 
this procedure may result in injury to 
hand or fingers and may damage the 
starter mechanism.
Important adjustments
!Warning!
To reduce the risk of personal injury from 
loss of control or contact with the 
running chain, do not use a saw with 
incorrect idle adjustment. At correct idle 
speed, the chain should not rotate. For 
directions to adjust idle speed, see the 
appropriate section of your owner's 
manual . If you cannot set the correct 
idle speed, have your STIHL dealer 
check your saw and make proper 
adjustments or repairs.
!Warning!
Proper tension of the chain is extremely 
important. In order to avoid improper 
setting, the tensioning procedure must 
be followed as described in your 
manual. Always make sure the 
hexagonal nut(s) for the sprocket cover 
is (are) tightened securely after 
tensioning the chain. Never start the saw 
with the sprocket cover loose. 
Check chain tension once more after 
having tightened the nut(s) and 
thereafter at regular intervals (whenever 
the saw is shut off). If the chain becomes 
loose while cutting, shut off the engine 
and then tighten. Never try to tighten the 
chain while the engine is running! After 
adjusting a chain, start the saw, let the 
engine run for a while, then switch 
engine off and recheck chain tension.
Working Conditions
!Warning!
The chainsaw produces 
poisonous exhaust gases 
as soon as the engine 
starts. These gases may 
be odorless and invisible. Operate your 
chainsaw outdoors only in a well 
ventilated area. 
To reduce the risk of serious or fatal 
injury from inhaling such poisonous 
gases, never work indoors or in 
enclosed spaces since you may inhale 
poisonous fumes.
!Warning!
Use of this product (including 
sharpening 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.
