5. Place the guide bar on the mounting surface by sliding the guide bar slot over the
alignment flanges, making sure that the tension adjusting pin is inserted in the
lower hole in the tail of the bar (Fig. 26a).
6. Replace the side cover and lightly tighten the side cover knob by turning it
clockwise. The bar must be free to move for tension adjustment.
NOTICE:
To extend the guide bar life, invert the bar occasionally.
CAUTION:
The saw chain must be properly tensioned before using.
7. Remove all the slack from the chain by turning the chain-tensioning
knob clockwise until the chain seats snugly against the guide bar with
the drive links in the guide bar groove.
8. Lift the tip of the guide bar
up to check for sag (Fig.
27). Release the tip of the
guide bar and turn the
chain-tensioning knob once
clockwise. Repeat this process
until the sag is eliminated.
9. Hold the tip of the guide bar up
and tighten the side cover knob
securely. The chain is correctly
tensioned when there is no sag on
the underside of the guide bar and the chain is snug, but it can be turned by hand
without binding.
NOTICE:
If chain is too tight, it will not rotate. Loosen the side cover knob
slightly and turn the tensioning knob once from right to left. Lift the tip of the
guide bar up and retighten the side cover knob securely. Assure that the
chain will rotate without binding.
