MAINTENANCE
Remove the old chain from the bar.
Lay out the new saw chain in a loop and
straighten any kinks. The cutters should face
in the direction of chain rotation. If they face
backwards, turn the loop over.
Place the chain drive links into the bar groove as
shown.
NOTE:
Make certain of direction of chain.
Position the chain so there is a loop at the back
of the bar.
While holding the chain in position on the bar,
reinsert the bar and chain through the opening
between the jaws and place the loop around
the sprocket.
Fit the bar flush against the mounting surface
so that the bar stud is in the long slot of the bar.
WARNING:
When placing the bar on the bar studs, ensure
that the chain tensioning pin is in the chain ten-
sion pin hole. Failure to properly place the chain
tensioning pin in the chain tensioning pin hole
could cause the chain to come loose, resulting
in serious personal injury.
Remove all slack from chain by turning the chain
tensioning screw clockwise, assuring that the
chain seats into the bar groove during tension-
ing.
Lift the tip of the bar up to check for sag. Re-
lease the tip of the bar, and turn the chain ten-
sioning screw 1/2 turn clockwise. Repeat this
process until sag does not exist.
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.
Replace the chain cover. Reinstall the chain
cover bolt and tighten securely.
