NOTE: New chain tends to stretch; check chain
tension frequently and tension as required.
NOTICE:
Chain tensioned while warm, can be too tight
upon cooling. Check the "cold tension" before
next use.
REPLACING THE BAR AND CHAIN
See Figures 14 - 17.
WARNING:
To avoid possible serious injury, stop the motor
and remove the battery pack before replacing
the bar, chain, or performing any maintenance
operation.
 Using the hex key provided, remove the chain
cover screw, lock washer, and chain cover from
the pole saw.
 The bar contains a slot that fits over the mount-
ing post. The bar also contains a chain tension-
ing pin hole which fits over the chain tensioning
pin.
 Place the bar onto the mounting post so that the
chain tensioning pin fits into the chain tensioning
pin hole.
NOTE: If necessary, rotate the chain tensioning
screw counterclockwise until the pin and hole
can be aligned.
 Fit the chain over the sprocket and into the bar
groove. The cutters on the top of the bar should
face toward the bar tip, in the direction of the
chain rotation.
 Replace the chain cover and reinstall the washer
and screw. Tighten the screw finger tight only.
The bar must be free to move for tension adjust-
ment.
 Remove all slack from chain by turning the chain
tensioning screw clockwise, assuring that the
chain seats into the bar groove during tension-
ing.
 Tighten the chain cover screw securely.
NOTE: Chain is correctly tensioned when there is
no slack on the underside of the bar, the chain is
snug, but it can be turned by hand without binding.
