Always place the switch in the
STOP “ O ” posi-
tion before you work on the saw.
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.
Remove the bar mounting nuts using the com-
bination wrench provided.
Remove the clutch cover and the outer guide
bar plate.
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.
NOTE: When placing the bar on the bar studs,
ensure that the adjusting pin is in the chain ten-
sion pin hole.
Replace the outer guide bar plate ensuring that
the bar pin groove is at the bottom with the
upper and lower edges angled away from the
guide bar.
