pin moves the bar forward and back-
ward as the screw is turned.

J_WARNING:
Wear protective gloves
when handling chain. The chain is sharp and
can cut you even when it is not moving.

make sure the chain brake nuts are finger
tight only. Attempting to tension the chain
when the chain brake nuts are tight can
cause damage.

ment tool (bar tool) to move chain around
guide bar. If the chain does not rotate, it is too
