3. Fit the chain around the bar ensuring that the direction of
the chain is as depicted in the picture on the bar. Fit the chain
on the sprocket. Adjust the position of chain tensioner so the
tensioner pin locates in the hole (A) on the bar.
4. Adjust the tension to ensure that there is not too much
slack in the chain. Make sure the tensioner pin (B) is located
in the assembly hole (A) on the bar. Pay attention to the
correct direction of the saw chain. Compare with the picture
near the chain sprocket and the picture on the bar.
5. Fit the chain cover to the power unit and fasten the nuts to
the chainsaw, ensure these are fastened as tight as possible
using your fingers only.
6. While holding up the tip of the bar, adjust the chain tension
by turning the adjustment wheel until the chain engagesin the
bar channel. When tensioned correctly, it should be possible
to pull one full chain link free of the bar channel with ease.
7. Tighten the wheel as secure as you can using your fingers.
Then check the chain for smooth rotation and proper tension
while moving it by hand. If necessary, loosen the chain cover.
8. Tighten the tensioner wheel.
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
TIGHT the V-drive wheel, chain bar, chain and crank
shaft bearing will suffer premature wear. Below Fig.
shows the correct tension A (when cold) and tension
B (when warm).
Fig. C shows a chain that is too loose.
