• Disconnect chainsaw from power supply.
• Rotate the chain cover lock knob counter-clockwise, and remove knob (see Fig. 23).
• Remove the chain cover (see Fig. 24).
• Remove the bar and chain from the mounting surface (see Fig. 24).
• Remove the old chain from the bar (see Fig. 24).
• 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 (see Fig. 25).
• Place the chain drive links into the bar groove as shown (see Fig. 26).
NOTE: Make certain of direction of chain.
• Position the chain so there is a loop at the back of the bar (see Fig. 26).
• 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.
• When placing the bar on the bar studs, ensure that the adjusting pin is in the chain tension
pin hole (see Fig. 29).
• 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 (see Fig. 27).
