 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.

NOTE: If chain is too tight, it will not rotate.
Loosen the chain cover bolt slightly and turn chain
tensioning screw 1/4 turn counterclockwise. Lift
the tip of the bar up and retighten bolt. Ensure that
the chain will rotate without binding.
 Return the lower jaw to the closed position by
pulling back on the front handle and allowing the
handle to move all the way forward.
