far as it will go to the rear. This should allow
the pin to be near the correct position. Fur-
ther adjustment may be necessary as you
mount the bar.
S
Mount the bar as illustrated.
S
Slide the bar toward the rear of the saw as
far as possible.
S
Prepare the chain by checking the proper
direction. Without following the illustration
it is easy to place the chain on the saw the
wrong direction. Use the illustration of the
chain to determine the proper direction.
S
Place the chain onto the sprocket located
behind the clutch drum (see illustration).
Fit the chain between the teeth in the
sprocket.
S
Start at the top of the bar and fit chain into
groove around the guide bar.
S
After chain is installed, pull bar forward un-
til chain is snug in the groove of the bar.
S
Hold guide bar against the saw frame mak-
ing sure the adjusting pin is aligned with
the hole in the bar. Remember this pin
moves the bar forward and backward as
screw is turned. Install the chain brake.
S
Replace the chain brake nuts and tighten
finger tight. Once the chain is tensioned
you will need to tighten chain brake nuts.

CHAIN TENSION
(Including units with
chain already installed)
NOTE
: When adjusting chain tension,
make sure the bar nuts are finger tight only.
Attempting to tension the chain when the bar
nuts are tight can cause damage.
Checking the tension:
Use the screwdriver end of the chain adjust-
ment tool (bar tool) to move the chain around
the bar. If the chain does not rotate, it is too
tight. If too loose, the chain will sag below the
bar.
Adjusting the tension:
Chain tension is very important. Chain
stretches during use. This is especially true
during the first few times you use your saw.
Always check chain tension each time you
use and refuel your saw.
Adjusting
Screw
You can adjust chain tension by loosening
the bar clamp nuts and turning adjusting
screw 1/4 of a turn while lifting up on the bar.
S
If chain is too tight, turn adjusting
screw 1/4 turn counterclockwise.
S
If chain is too loose, turn adjusting
screw 1/4 turn clockwise.
S
Lift up the tip of the bar and tighten the bar
clamp nuts with the combination screw-
driver/wrench.
S
Recheck chain tension. Tension is correct
when chain does not sag below the bar but
still can be moved around the bar.
WARNING:
If the chain is operated
with a loose chain, the chain could jump off
the guide bar and result in serious injury.
