Note: for emergency stopping, simply activate chain brake and switch the I/O
(on/off) switch to O (off).
10.5 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 definitely
following any chain brake service.
Test chain brake as follows:
▪ Place saw on a clear, firm, flat surface.
▪ Start engine.
▪ Grasp the rear handle (A) with your right hand (Fig. 10).
▪ With your left hand, hold the front handle (B) [not chain brake lever (C)] firmly (Fig. 10).
▪ Squeeze the throttle trigger to 1/3 throttle, then immediately activate the chain brake lever
(C) (Fig. 10).
Warning: activate the chain brake slowly and deliberately. Keep the chain
from touching anything; don t let the saw tip forward.
▪ 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 centre for service.
▪ 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 centre for service.
10.6 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 excessive wear of bar
from overheating. Too little oil is evidenced by smoke, bar discoloration or pitch build-up. To
ensure the bar and chain receive oil, only use the original style bar with the oil passage hole (A)
as illustrated above (Fig. 3a).
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.
10.7 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.
