3. Tighten the bar knob securely (clockwise). Hand tighten only!
NOTE: When tensioned correctly, it should be possible to pull
one full chain link free of the bar channel with ease.
A new chain will expand its length during the first period of
use. Check and re-adjust the tension frequently as a loose
chain can easily derail or cause rapid wear of the chain and
the chain bar.
CAUTION! If the saw chain is TOO LOOSE or TOO TIGHT the
clutch, chain bar, chain and crank shaft bearing will suffer
premature wear. Above figure shows the correct tension A
(when cold) and tension B (when warm). C shows a chain that
is too loose.
4. Tighten the chain cover.
