5 - OPERATING INSTRUCTIONS
5-3. RE-STARTING A WARM ENGINE
1.Make sure the on/off switch is in the “I” position.
2.Move the choke lever out as far as it will go. Then, push the choke lever back in completely. This advances the throttle so you do not have to hold trigger while starting.
3.Depress the primer bulb 10 times.
4.Pull the starter rope rapidly 4 times. The engine should start.
5.Depress the safety trigger and squeeze and release the throttle trigger for idle.
5-4. TO STOP ENGINE
1.Release trigger and allow engine to return to idle speed.
2.Press STOP switch down to stop engine Figure

INERTIA CHAIN BRAKE® ACTION :
NOTE: THIS SAW IS EQUIPPED WITH AN INERTIA CHAIN BRAKE.IF THE SAW KICKS BACK WHILE IN USE, THE INERTIA OF THE MOVING SAW WILL ACTI- VATE THE BRAKE. A BRAKE BAND AROUND THE CLUTCH DRUM ACTIVATES AND STOPS THE MOVING CHAIN.
5-5.CHAIN BRAKE® OPERATIONAL TEST
Test the CHAIN BRAKE® periodically to ensure proper function.
Perform a CHAIN BRAKE® test prior to initial cutting, follow- ing extensive cutting, and definitely following any CHAIN BRAKE® service.
TEST CHAIN BRAKE® AS FOLLOWS:
1.Place saw on a clear, firm, flat surface.
2.Start engine.
3.Grasp the rear handle (A) with your right hand (Figure
4.With your left hand, hold the front handle (B) [not CHAIN BRAKE® lever (C)] firmly (Figure
5.Squeeze the throttle trigger to 1/3 throttle, then imme- diately activate the CHAIN BRAKE® lever (C) (Figure 5- 5A).
WARNING
Activate the CHAIN BRAKE® slowly and deliberately. Keep the chain from touching anything; don’t let the saw tip for- ward.
6.Chain should stop abruptly. When it does, immediately release the throttle trigger.
WARNING
If chain does not stop, turn engine off and take your unit to the nearest Authorized Service Center for service.
7.If CHAIN BRAKE® functions properly, turn the engine off and return the CHAIN BRAKE® to the DISEN- GAGED position.

5-6.SAW CHAIN / BAR 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 exces- sive wear of bar from overheating. Too little oil is evidenced by smoke, bar discoloration or pitch
NOTE: Saw chain stretches during use, particularly when it is new, and it will occasionally be necessary to adjust and tighten it. New chain will require adjustment after about 5 minutes of operation.
5-7.AUTOMATIC OILER
Your chain saw is equipped with an automatic clutch 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. There is no flow adjustment. The oil reservoir will run out at approxi- mately the same time as the fuel supply runs out.
