The muffler and other parts of the engine
(e.g. fins of the cylinder, spark plug)
become hot during operation and remain
hot for a while after stopping the engine.
To reduce risk of burns do not touch the
muffler and other parts while they are
hot. Don't work alone. Keep within
calling distance of others in case help is
needed.
Your chainsaw is equipped with a chain
catcher. It is designed to reduce the risk
of personal injury in the event of a
thrown or broken chain. From time to
time the catcher may be damaged or
removed.
To reduce the risk of personal injury, do
not operate a chainsaw with a damaged
or missing catcher.
Inspect buffers periodically. Replace
damaged, broken or excessively worn
buffers immediately, since they may
result in loss of control of the saw.
A "sponginess" in the feel of the saw,
increased vibration or increased
"bottoming" during normal operation
may indicate damage, breakage or
excessive wear. Buffers should always
be replaced in sets. If you have any
questions as to whether the buffers
should be replaced, consult your STIHL
servicing dealer.

Warning!
Take extreme care in wet and freezing
weather (rain, snow, ice). Put off the
work when the weather is windy, stormy
or rainfall is heavy.
!
Warning!
Avoid stumbling on obstacles such as
stumps, roots or rocks and watch out for
holes or ditches. Clear the area where
you are working. Be extremely cautious
when working on slopes or uneven
ground. There is increased danger of
slipping on freshly debarked logs.
!
Warning!
To reduce the risk
of serious or fatal
injury to the
operator or
bystanders, never
use the saw with one hand.
You cannot control reactive forces and
you may lose control of the saw, which
can result in the skating or bouncing of
the bar and chain along the limb or log.
Even for those compact saws designed
for use in confined spaces, one-handed
operation is dangerous because the
operator may lose control.
Cutting Instructions
Grip: Always hold the saw 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-handers should
follow these instructions too.
Wrap your fingers tightly around the
handles, keeping the handles cradled
between your thumb and forefinger. With
your hands in this position, you can best
oppose and absorb the push, pull and
kickback forces of your saw without
losing control (see section on reactive
forces). Make sure your chainsaw
handles and grip are in good condition
and free of moisture, pitch, oil or grease.
!
Warning!
Do not operate your chainsaw with the
starting throttle lock engaged. Cutting
with the starting throttle lock engaged
does not permit the operator proper
control of the saw or chain speed.
