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. Turn the bar knob counterclockwise to slightly loosen the bar
cover (Fig. 39). DO NOT remove the bar cover.
2. Hold the guide bar tip up (Fig. 40) and turn the chain-tensioning
ring to adjust the tension (Fig. 41).
• Turn the chain-tensioning ring clockwise to tighten the saw chain.
• Turn the chain-tensioning ring 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. 42).
3. Continue to hold the guide bar tip up (Fig. 40). Turn the bar knob
clockwise to securely tighten the bar cover (Fig. 39).
CAUTION:
If the saw chain was tensioned while warm, it
may become too tight when cooled. Loosen the chain
tension after operation and check the chain tension before
the next use.
