CHAIN / BAR LUBRICATION
Adequate lubrication of the saw chain is essential at all
times to minimize friction with the guide bar.
5-4A
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 build-up.
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.
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.

OILER
Test the CHAIN BRAKE
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.
