 If the engine starts, runs, and accelerates,
but will not idle, turn the idle speed screw "T"
clockwise to increase idle speed.
 If the chain turns at idle, turn the idle speed
screw "T" counterclockwise to reduce the
idle RPM and stop the chain movement. If the
saw chain still moves at idle speed, contact an
authorized service center for adjustment and
discontinue use until the repair is made.
WARNING:
THE SAW CHAIN SHOULD NEVER TURN AT
IDLE. Turn the idle speed screw "T" counter-
clockwise to reduce the idle RPM and stop the
chain, or contact an authorized service center
for adjustment and discontinue use until the
repair is made. Serious personal injury could
result from the saw chain turning at idle.
PULL AND PUSH
See Figure 14.
The reaction force of the saw is always opposite to
the direction the chain is moving. Thus, the operator
must be ready to control the PULL when cutting
on the bottom edge of the bar and the PUSH when
cutting along the top edge.
NOTE: The chain saw has been fully factory
tested. It is normal to find some slight oil residue
on the saw.
OPERATION
PULL
PUSH
WARNING:
KICKBACK occurs when the moving chain
contacts an object at the upper portion of the
tip of the guide bar or when the wood closes in
and pinches the saw chain in the cut. Contact
at the upper portion of the tip of the guide bar
can cause the chain to dig into the object and
stop the chain for an instant. The result is a
lightning-fast reverse reaction which kicks the
guide bar up and back toward the operator. If
the saw chain is pinched along the top of the
guide bar, the guide bar can be driven rapidly
back toward the operator. Either of these reac-
tions can cause loss of saw control, which can
result in serious injury.
Do not rely exclusively upon the safety devices
built into the saw. As a chain saw user, you
should take steps to keep your cutting jobs
free from accident or injury. See General Safety
Rules for more details.
