NOTE: A new saw chain tends to stretch and will need readjustment after as few as ve (5) cuts. This is
normal during the break-in period. The interval between future adjustments will lengthen quickly.
1. Loosen the bar-retaining nuts, but do not remove them (Fig. 15).
2. Hold the guide bar tip up (Fig. 19) and use a at-head screwdriver to turn the chain-tensioning
screw (Fig. 20).
• Turn the chain-tensioning screw clockwise to tighten the saw chain.
• Turn the chain-tensioning screw counterclockwise to loosen the saw chain.
The saw chain should t snuggly against the underside of the guide bar. There should be no sag (Fig. 21).
3. Continue to hold the guide bar tip up. Tighten the bar-retaining nuts securely.
4. Move the saw chain back and forth on the guide bar. If the saw chain does not move freely, loosen
the chain tension.
