DANGER
Operating Instructions
WARNING
Do not operate your chain saw 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. Begin
cutting with the saw at full throttle,
engage the bumper spike firmly in the
wood (if possible) and then continue
cutting. Always work with the bumper
spike so that you have better control of
the saw. If you work without the bumper
spike the saw may pull you forwards
suddenly.
WARNING
Never touch a chain with your hand or
any part of your body when the engine is
running, even when the chain is not
rotating.
In the event of an emergency, switch off
the engine immediately – move the
master control lever to 0 or STOP.
WARNING
Always stop the engine before putting a
chain saw down.
WARNING
The saw chain continues to move for a
short period after the throttle trigger is
released (flywheel effect).
Accelerating the engine while the saw
chain is blocked increases the load and
will cause the clutch to slip continuously.
This may occur if the throttle is
depressed for more than a few seconds
when the chain is pinched in the cut or
the chain brake is engaged. It can result
in overheating and damage to important
components (e. g. clutch, polymer
housing components) – which can then
increase the risk of injury, e. g., from the
saw chain moving while the engine is
idling.
WARNING
Your chain saw 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 chain saw with a
damaged or missing chain catcher.
WARNING
Inspect antivibration elements
periodically. Replace damaged, broken
or excessively worn antivibration
elements 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. Antivibration elements
should always be replaced in sets. If you
have any questions as to whether the
antivibration elements should be
replaced, consult your STIHL servicing
dealer.
If this tool is subjected to unusually high
loads for which it was not designed (e. g.
heavy impact or a fall), always check
that it is in good condition before
continuing work. Check in particular that
the fuel system is tight (no leaks) and
that the controls and safety devices are
working properly. Do not continue
operating this machine if it is damaged.
In case of doubt, have it checked by your
STIHL servicing dealer.
Your saw is not designed for prying or
shoveling away limbs, roots or other
objects. Such use could damage the
cutting attachment or AV system.
WARNING
When sawing, make sure that the saw
chain does not touch any foreign
materials such as rocks, fences, nails
and the like. Such objects may be flung
off, damage the saw chain or cause the
saw to kickback.
WARNING
Take special care when cutting
shattered wood because of the risk of
injury from slivers being caught and
thrown in your direction.
To reduce risk of electro-
cution, take extra
precautions when cutting
near power lines. Have
the power switched off
before starting cutting
work in the immediate
vicinity of power lines.
