chainsaw and fasten the nuts until finger tight.
7. While holding up the tip of the bar, adjust the chain tension by
turning the tensioner screw until the chain engages in the bar
channel.
Note: when tensioned correctly it should be possible to pull
one full chain link free of the bar channel with ease.
8. Tighten the nuts securely with the bar tip supported (12-15
Nm). Then check the chain for smooth rotation and proper
tension while moving it by hand. If necessary, loosen the chain
cover.
9. Tighten the tensioner nuts.
Note: 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 itself and the chain bar.
Caution: If the saw chain is TOO LOOSE or TOO TAUT, the Vdrive
wheel, chain bar, chain and crank shaft bearing will suffer
premature wear. FIG 8 shows the correct tension A (when cold)
and tension B (when warm). FIG C shows a chain that is too loose.
