Adjusting Chain Tension (Fig. A, E )

CAUTION: Sharp chain. Always wear protective
gloves when handling the chain. The chain is sharp
and can cut you when it is not running.

WARNING: Sharp moving chain. To prevent
accidental operation, ensure that battery is removed
from the tool before performing the following
operations. Failure to do this could result in serious
personal injury.
1. With the saw on a flat, firm surface, check the saw chain
5 tension. The tension is correct when the chain snaps
back after being pulled 1/8" (3 mm) away from the
guide bar with light force from the index finger and
4
thumb as shown in Figure E. There should be no "sag"
between the guide bar and the chain on the underside
as shown in Figure E.
2. To adjust saw chain tension, flip up locking tab and
rotate the bar adjust locking knob
one full turn. Rotate the chain tensioning knob
clockwise until the chain tension is correct as
9
instructed above.
3. Do not over-tension the chain as this will lead to
excessive wear and will reduce the life of the bar
and chain.
4. Once chain tension is correct, securely tighten bar adjust
locking knob.
nOTE: The bar adjust locking knob has a detent tightening
system. The sprocket cover is secure after three audible
clicks are heard. Further tigtening is not required.
5. When the chain is new, check the tension frequently
(after removing battery) during the first 2 hours of use as
a new chain stretches slightly.
