5. Fit the chain cover to the power unit and fasten the
nuts to finger tightness.
6. While holding up the tip of the bar, adjust the chain
tension by turning the tensioner screw until the tie
straps just touch the bottom side of the bar rail.
7. Tighten the nuts securely with the bar tip held up
(12 ~ 15 N·m). Then check the chain for smooth ro-
tation and proper tension while moving it by hand. If
necessary, readjust with the chain cover loose.
8. Tighten the tensioner screw.
NOTE
A new chain will expand its length in the beginning of
use. Check and readjust the tension frequently as a loose
chain can easily derail or cause rapid wear of itself and
the guide bar.
