 Remove the battery pack before you do any
work on the chain saw.
 Rotate the chain cover lock knob counterclock-
wise and remove knob.
 Remove the chain cover.
 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

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-
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.
