Make sure the chain brake is not set by pulling
the chain brake lever/hand guard towards the
front handle to the run position.
NOTE: When replacing the guide bar and chain,
always use the specified bar and chain listed in
the Bar and Chain Combinations section later
in this manual.
Wear gloves when handling the chain and bar.
These components are sharp and may contain
burrs.
Press in on the clutch cover lock knob and rotate
counterclockwise until the clutch cover can be
removed.
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
chain tensioning pin hole and that both bar
studs are securely in their respective holes in
the clutch cover.
NOTE: The adjusting pin may need to be slightly
repositioned with the chain tensioning dial so
that it is aligned with the position of the bar chain
tensioning pin hole.
Rotate clutch cover lock knob just enough to
hold the cover in position.
NOTE: The bar must be free to move for chain
tension adjustment.
Lift the tip of the guide bar up to check for sag.
Remove all slack from the chain by rotating the
chain tensioning dial clockwise until the chain
seats snugly against the bar with the drive links
in the bar groove.
Release the tip of the guide bar and, if the chain
sags, turn the chain tensioning dial clockwise.
Repeat this process until sag does not exist.
Hold the tip of the guide bar up and tighten the
clutch cover lock knob securely.
