The second recommended method for
starting your chain saw allows you to
start the saw without placing it on the
ground. Make sure the chain brake is
engaged, grip the front handle of the
chain saw firmly with your left hand.
Keep your arm on the front handle in a
locked (straight) position. Hold the rear
handle of the saw tightly between your
legs just above the knees. Maintain
good balance and secure footing. Pull
the starting grip slowly with your right
hand until you feel a definite resistance
and then give it a brisk, strong pull.
WARNING
Be sure that the guide bar and saw chain
are clear of you and all other
obstructions and objects, including the
ground. When the engine is started, the
engine speed with the starting throttle
lock engaged will be fast enough for the
clutch to engage the sprocket and, if the
chain brake is not activated, turn the saw
chain. If the upper quadrant of the tip of
the bar touches any object, it may cause
kickback to occur (see section on
reactive forces). To reduce this risk,
always engage the chain brake before
starting. Never attempt to start the chain
saw when the guide bar is in a cut or
kerf.
Once the engine has started,
immediately blip the throttle trigger,
which should release the Master Control
lever to the run position and allow the
engine to slow down to idle.
Always disengage chain brake before
accelerating engine and before starting
cutting work. The only exception to this
rule is when you check operation of the
chain brake. High revs with the chain
brake engaged (chain locked) will
quickly damage the powerhead and
chain drive (clutch, chain brake).
WARNING
When you pull the starter grip, do not
wrap the starter rope around your hand.
Do not let the grip snap back, but guide
the starter rope to rewind it properly.
Failure to follow this procedure may
result in injury to your hand or fingers
and may damage the starter
mechanism.
Important Adjustments
WARNING
To reduce the risk of personal injury
from loss of control and / or contact with
the running cutting tool, do not use your
chain saw with incorrect idle adjustment.
At correct idle speed, the cutting tool
should not move. For directions on how
to adjust idle speed, see the appropriate
section of your instruction manual.
If you cannot set the correct idle speed,
have your STIHL dealer check your
chain saw and make proper adjustments
and repairs.
Holding and Controlling the Chain Saw
Always hold the chain saw firmly with
both hands when the engine is running.
Place your left hand on the front handle
bar and your right hand on the 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).
WARNING
To reduce the risk of seri-
ous or fatal injury to the
operator or bystanders
from loss of control,
never use the chain saw
with one hand. It is more
difficult for you to control
reactive forces and to
prevent the bar and chain
from skating or bouncing
along the limb or log.
