4. Remove the plastic shipping spacer (if present).
5. An adjustment pin and screw is used to adjust
the tension of the chain. It is very important when
assembling the bar that the adjustment pin (A)
passes through the lower bar pin hole (B). Turning
the screw (C) will move the adjustment pin up and
down the screw. Locate this adjustment pin before
you begin mounting the bar onto the saw. See
following illustration.
6. Use the screwdriver end of the bar tool to turn
the adjustment screw counterclockwise. Turn the
screw until the adjustment pin (A) is located all
the way to the right side of the adjustment travel
pocket as shown in view above. This should allow
the pin to be near the correct position.
7. Slide guide bar on bar bolts until guide bar stops
against clutch drum sprocket.
8. Carefully remove the chain from the package. Hold
chain with the drive links as shown.

12. Pull guide bar forward until chain is snug in guide
bar groove. Ensure all drive links are in the bar
groove.
13. Now, install clutch cover making sure the
adjustment pin is positioned in the lower bar pin
hole. Remember this pin moves the bar forward
and backward as the screw is turned.

chain is tensioned, you will need to tighten bar
nuts.

CHAIN TENSION

(Including units with chain already installed)
a WARNING: Wear protective gloves when
handling chain. The chain is sharp and can
cut you even when it is not moving.
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 adjustment tool
(bar tool) to move chain around guide bar. If the chain
does not rotate, it is too tight. If the chain is too loose,
it will sag below the bar.
