OPERATION
Follow the simple direction for easy cutting:
When the log is supported along the entire length, it is
■
cut from the top (overbuck) (Fig. 12).
When the log is supported on one end, cut 1/3 of the
■
diameter from the underside (underbuck). Then make
the finished cut by overbucking to meet the first cut
(Fig. 13).
When the log is supported on both ends, cut 1/3 of
■
that diameter from the top (overbuck). Then make the
finished cut by underbucking the lower 2/3 to meet
the first cut (Fig. 14).
When bucking on a slope always stand on the uphill
■
side of the log. When "cutting through", to maintain
complete control, release the cutting pressure near
the end of the cut without relaxing your grip on the
chainsaw handles.
Do not let the chain contact the ground. After completing
the cut, wait for the saw chain to stop before you move
the chainsaw. Always stop the motor before moving from
tree to tree.

MAINTENANCE

CHAIN SHARPENING (Fig. 15 - 18)
When the chain penetrates into wood with difficulty,
it needs sharpening as follows:
Put the chain under tension.
■
Fasten the bar in a vice so that the chain can slide.
■
Fasten the file to the file holder and place it on cutter
■
at a 35° angle.
File with forward strokes only until all the worn out
■
part of the cutting edge is taken away.
Count the number of strokes given to the cutter taken
■
as a reference basis and file away for the same
number of strokes on all other cutters.
If after sharpening a few times, the depth gauge
■
protrudes from the template, you must reset its level
using a flat file.
Finally, round off the depth gauge.
■
NOTE: We advise you to have the deep or important
sharpening carried out by a service agent who is
equipped with electric sharpener.

GUIDE BAR MAINTENANCE (Fig. 19 - 21)
When you have finished working, clean out the groove
■
and the oil passages, with a special scraping hook.
Periodically trim the sides of rails using a flat file.
■
If not done in the long run, the "featheredges" might
break away and damage the bar.
If one rail is higher than the other one, it is necessary
■
to make it even with a flat file and then smooth them
with a file or fine grain abrasive paper.
