 Hold the chain in position on the bar and place
the loop around the sprocket.
 Fit the bar flush against the mounting surface so
that the bar studs are 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.
 Replace the chain cover.
 Replace the chain cover lock knob; rotate knob
clockwise to tighten. The bar should still be free
to move for tension adjustment.
 Remove all slack from the chain by turning the
chain tensioning knob clockwise until the chain
seats snugly against the bar with the drive links
in the bar groove.
 Lift the tip of the guide bar up to check for sag.
 Release the tip of the guide bar and turn the
chain tensioning knob 1/2 turn clockwise.
Repeat this process until sag does not exist.
 Hold the tip of the guide bar up and tighten the
chain cover lock knob.
The chain is correctly tensioned when there is no
sag on the underside of the guide bar, the chain is
snug, but it can be turned by hand without binding.
NOTE: If chain is too tight, it will not rotate. Loosen
the chain cover lock knob slightly and turn the
chain tensioning knob 1/4 turn counterclockwise.
Lift the tip of the guide bar up and retighten the
chain cover lock knob. Ensure that the chain will
rotate without binding.
