 Remove the bar mounting nuts using the com-
bination wrench provided or a 13 mm socket
wrench.
 Remove the clutch 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 shown.
 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.
 Replace the clutch cover ensuring that the
adjusting pin in the clutch cover is in the bar
tensioning pin hole and that both bar studs are
in their respective holes in the clutch cover.
