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.
