 Remove the bar and chain from the mounting
surface.
 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.
 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-

tensioning pin in the chain tensioning pin hole
could cause the chain to come loose, resulting
in serious personal injury.

chain tensioning knob clockwise until the chain
seats snugly against the bar with the drive links
in the bar groove.
