tension while the unit is running. Always stop the engine and allow it to cool. Disconnect
the spark plug wire to prevent the unit from starting accidentally.
WARNING:
when handling or performing maintenance on the saw chain.
Check the chain tension before and during operation. The saw chain will expand as it heats up during
operation. Adjust the chain tension whenever the flats on the saw chain hang out of the bar groove
(Fig. 18 & Fig. 21).
NOTE: A new saw chain tends to stretch and will need readjustment after as few as five (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 flat-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 fit 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.
