Preparation for the use of the saw
Take off the chain guard and inspect for
safety in operation. For assembly, follow
the procedure described in the chapter
“Mounting the Bar and Chain” of your
owner's manual.
STIHL Oilomatic chain, guide bar and
sprocket must match each other in
gauge and pitch. Before replacing any
bar and chain, see the sections on
“Specifications”, kickback and the
ANSI B 175.1-2000 chainsaw kickback
standard in this manual. Since longer
bars add weight and may be more
difficult to control, select the shortest bar
that will meet your cutting needs. Check
the throttle trigger and throttle trigger
interlock for smooth action - throttle
trigger must return automatically to idle
position. The master control lever /stop
switch must move easily to stop and
$
.
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 antivibration
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.
Fueling
Your STIHL chainsaw uses an oil-gaso-
line mixture for fuel (see chapter “Fuel”
of your owner's manual).
!
Warning!
Gasoline is an extremely flammable fuel.
If spilled or ignited by a spark or other
ignition source, it can cause fire and
serious burn injury or property damage.
Use extreme caution when handling
gasoline or fuel mix.
Do not smoke or bring any
fire or flame near the fuel
or the chainsaw. Note that
combustible fuel vapors
may be vented from the
fuel system.
