MAINTENANCE AND REPAIR INSTRUCTIONS

SAW CHAIN TENSION ADJUSTMENT

WARNING:
when handling the saw chain.
Proper tension of saw chain is extremely important and
must be checked before starting, as well as during any
cutting operation.
Taking the time to make needed adjustments to the saw
chain will result in improved cutting performance and
prolonged chain life.
NOTE: A new chain and bar will need readjustment after
as few as 5 cuts. This is normal during the break-
in period, and the interval between future
adjustments will lengthen quickly (Fig. 22).
CAUTION:
TIGHT, the sprocket, bar, chain, and
crankshaft bearings will wear more rapidly.
Study Fig. 22 for information concerning
correct cold tension (A), correct warm
tension (B), and as a guide for when saw
chain needs adjustment (C).
To adjust the saw chain:
NOTE: Make sure the Chain Brake® is disengaged.
Disengage the Chain Brake® (D) by pulling it backward
(Fig. 23).
1. Tensioning the chain can be accomplished with
relative ease. Turn bar bolt knob (E) counter clock
wise. Then turn ring (F) counter clock wise to loosen
chain or clock wise to tighten chain (Fig. 24).

2. After adjustment and while wearing heavy duty work
gloves, move the saw chain back and forth on the
guide bar to be sure the chain moves freely and is in
proper mesh with sprocket.
NOTE: If the chain is difficult to rotate or if it binds on the
guide bar, too much tension has been applied
and must be adjusted as described in step 1.
3. While applying tension to the chain, hold the tip of
the bar up and then tighten the bar bolt knob (E).
