English
always check that it is in good condition
before continuing work. Check in
particular that the controls and safety
devices are working properly. Do not
continue operating this chain saw if it is
damaged. In case of doubt, have it
checked by your STIHL servicing dealer.
Your chain saw is not designed for
prying or shoveling away limbs, roots or
other objects. Such use could damage
the cutting attachment.
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
chain saw to kickback.
WARNING
If the rotating saw chain strikes a rock or
other hard object, sparks may be
created, which can ignite flammable
materials under certain circumstances.
Flammable materials can include dry
vegetation and brush, particularly when
weather conditions are hot and dry. Do
not use your chain saw around
flammable materials or around dry
vegetation or brush when there is a risk
of fire or wildfire. Contact your local fire
authorities or the U.S. Forestry Service if
you have any question about whether
vegetation and weather conditions are
suitable for the use of a chain saw.

WARNING
Take special care when cutting
shattered wood because of the risk of
injury from slivers being caught and
thrown in your direction.
Check the cutting attachment at regular
short intervals during operation, or
immediately if there is a noticeable
change in cutting behavior:
Switch off the motor.
–
Move front hand guard to ƒ.
–
Disconnect the plug from the power
–
supply.
The motor is not water-
proof. Never work with
the chain saw in the rain
or in wet or very damp
locations.
Do not leave the machine outdoors in
the rain.
DANGER
Do not rely on the chain
saw 's insulation against
electric shock. To reduce
the risk of electrocution,
never operate this chain
saw in the vicinity of any
wires or cables (power,
etc.) which may be carry-
ing electric current. To
reduce risk of electrocu-
tion, take extra
precautions when cutting
near power lines. Have
the power switched off
before starting cutting
work in the immediate
vicinity of power lines.
REACTIVE FORCES INCLUDING
KICKBACK
WARNING
Reactive forces may occur any time the
chain is rotating. Reactive forces can
cause serious personal injury.
The powerful force used to cut wood can
be reversed and work against the
operator. If the rotating saw chain is
suddenly and significantly slowed or
stopped by contact with any solid object
such as a log or branch or is pinched, the
reactive forces may occur instantly.
These reactive forces may result in loss
of control, which, in turn, may cause
serious or fatal injury. An understanding
of the causes of these reactive forces
may help you avoid the element of
surprise and loss of control. Surprise
contributes to accidents.
The most common reactive forces are:
kickback,
–
pushback,
–
pull-in.
