Operating the Chainsaw
Step 1 - Starting the Engine (continued)
CHAIN BRAKE OPERATIONAL TEST
Test the CHAIN BRAKE periodically to ensure proper function.
Perform a CHAIN BRAKE test prior to initial cutting, following extensive cutting, and de nitely following
any CHAIN BRAKE service.
TEST CHAIN BRAKE AS FOLLOWS:
1. Place saw on a clear, rm, at 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)] rmly (Fig. 10).
5. Squeeze the throttle trigger to Full Throttle, then immediately activate the CHAIN BRAKE lever (C)
(Fig. 10).
6. Chain should stop abruptly. When it does, immediately release the throttle trigger.
WARNING:
Activate the chain brake slowly and deliberately. Keep the chain from touching anything;
don t let the saw tip forward.
7. If chain brake functions properly, turn the engine off and return the chain brake to the
DISENGAGED position.
WARNING: If chain does not stop, turn engine off and take your unit to the nearest Authorized
Service Center for service.

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 ef ciency,
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.
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.
AUTOMATIC OILER
Your chainsaw 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
ow to the bar pad. There is no ow adjustment. The oil reservoir will run out at approximately the
same time as the fuel supply runs out.
WARNING: Don't put pressure on the saw when reaching the end of the cut. The pressure may
cause the bar and chain to rotate. If the rotating chain strikes some other object, a reactive force may
cause moving chain to strike the operator.
