NOTE: In some cases due to operating conditions
(altitude, temperature etc.) your chain saw may
need a slight adjustment to the idle speed. If unit
does not Idle after restarting 2 times, follow these
steps to adjust idle.
1. Idle adjustment access (L) - the symbol "T" (for
throttle) is below the adjustment hole (Fig. 8).
2. Using a Phillips or slotted screwdriver - turn screw
1/4 to 1/2 turn clockwise (to the right). Unit should
then idle properly (Fig. 9).
NOTE: If chain turns while idling - turn screw back to the
left until chain stops and unit continues to idle.
NOTE: When starting a warm engine, go back to Step 3.
Follow the steps until Step 8. Then, move the
lever to Position 3 and release the throttle trigger.
STOPPING INSTRUCTIONS
1. Release the trigger and allow the engine to return to
the idle speed.
2. Move the STOP switch to the STOP position.
NOTE: For emergency stopping, simply activate the
Chain Brake® and move the STOP switch down.

OTHER INSTRUCTIONS
Chain Brake® Test
1. Place saw on a clear, firm, flat surface.
2. Start engine.
3. Grasp the rear handle (A) with your right hand (Fig. 10).
4. With your left hand, hold the front handle (B) [not
Chain Brake® lever (C)] firmly (Fig. 10).
5. Squeeze the throttle trigger to 1/3 throttle, then imm-
ediately activate the Chain Brake® lever (C) (Fig. 10).
6. Chain should stop abruptly. When it does,
immediately release the throttle/trigger.
7. If Chain Brake® functions properly, turn the engine
off and return the Chain Brake® to the DISENGAGED
position.
Chain Lubrication
Adequate lubrication of the saw chain is essential at all
times to minimize friction with the guide bar. Never starve
the bar and chain of oil. Running the saw with too little oil
will decrease cutting efficiency, shorten saw chain life,
cause rapid dulling of chain, and cause excessive wear
of bar from overheating. Too little oil is evidenced by
smoke, bar discoloration or pitch build-up.
Automatic Oiler
Your chain saw is equipped with an automatic gear driven
oiler system. The oiler automatically delivers the proper
amount of oil to the bar and chain. As the engine speed
increases, so does the oil flow to the bar pad. The amount
of oil flowing to the bar and chain may be changed by
turning the adjustment screw (D) as shown in Fig. 11.
Turn the screw clockwise to DECREASE oil flow and
counterclockwise to INCREASE the flow.
