Activate the CHAIN
BRAKE® slowly and
deliberately. Keep the chain from touching
anything; don’t let the saw tip forward.
WARNING:
If chain does not
stop, turn engine off
and take your unit to the nearest Authorized
Service Center for service.

CHAIN BRAKE TEST
1. Place saw on a clear, firm, flat surface.
2. With the chain brake pulled back to the disengaged
position, start the 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 engage the Chain Brake® lever by pushing
forward (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) with a small slotted
screwdriver as shown in Fig. 11. Turn the screw clockwise
to DECREASE oil flow and counterclockwise to INCREASE
the flow.

STOPPING INSTRUCTIONS
1. Release the trigger and allow the engine to return to
the idle speed.
2. Move the STOP switch up to the STOP position (Fig.
4).
NOTE: For emergency stopping, push the lever of the
chain brake lever/hand guard (C) forward and
move the STOP switch up (Fig. 3, 4).
STARTING A COLD ENGINE
To be sure to add the correctly mixed fuel to the fuel tank
(A) and to add bar and chain oil to the oil tank (B). Make
sure the chain brake is disengaged (C) before starting the
unit.
1. Slide the STOP switch down (Fig. 4). The red choke
lever (H) has 3 positions: Positions 1, 2 and 3 (Fig. 6).
2. Fully press and release the primer bulb (G) 10 times,
slowly. Some amount of fuel should be visible in the
primer bulb (Fig. 5). If you can’t see fuel in the bulb,
press and release the bulb as many times as it takes
before you can see fuel in it.
3. Move the red choke lever (H) to Position 1 (Fig. 6).
NOTE: This unit will not run with the lever in Position 1.
4. Place the saw on a firm flat surface. Hold saw firmly
as shown (Fig. 7).
NOTE: The unit uses the INCREDI-PULL™ starting
system with MAX FIRE IGNITION™, which signifi-
cantly reduces the effort required to start the engine.
You must pull the starter rope out far enough to hear the
engine attempt to start. There is no need to pull the rope
briskly-- there is no harsh resistance when pulling. Be
aware that this starting method is vastly different from
(and much easier than) what you may be used to.
5. Hold down safety trigger (E) and squeeze the throttle
trigger (D). With thumb, press down on the throttle
latch (F). Release trigger (D) first. This will lock the
throttle into wide open position (Fig. 3). Pull the rope
with a controlled and steady motion 4 times.
6. Then move the red choke lever (H) to Position 2, being
sure to keep the throttle trigger locked. Hold saw firmly
and pull rope until saw starts. This could take 4 more
pulls.
7. Let the saw warm up for 10 seconds. Depress and
release throttle trigger (D) for idle.
8. Move red choke lever (H) to Position 3. If engine fails
to start, repeat these instructions. If engine does start,
begin chain brake test described on next page.
9. If unit idles roughly, there is an idle adjustment access
hole (L)(Fig. 8). 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.
STARTING A WARM ENGINE
1. Go back to step 6. Follow the steps until step 8.
2. Then move the red choke lever (H) to position 3 and
release the throttle trigger (D).
