• 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.

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.

bar.
NOTE: When placing the bar on the bar studs, ensure that the adjusting pin is in the chain
tension pin hole.
• Replace the chain cover.
• Replace the chain cover lock knob. Rotate knob clockwise to tighten. The bar should still be
free to move for tension adjustment.
• Remove all slack from the chain by turning the chain tensioning knob clockwise until the
chain seats snugly against the bar with the drive links in the bar groove.
• Lift the tip of the guide bar up to check for sag.
