KEEP YOUR CHAIN
PROPERLY MAINTAINED
1.
Maintain top angle basic 35 degrees.
2. File with straight even strokes.
3. Keep all cutters the same length.
4.
Use
14"
full round file.
Filing with the tooth, to maintain the approximate 30 degree angle from the vertical
as illustrated
in Figure 16-A hold the file approximately
5 degrees from horizontal,
with
the
handle low, (Figure 16).
1.
Use correct
14"
full round file.
2.
Keep 1/5 of file diameter
above top edge of cutter.
This produces the correct
undercut, see Figure 17-A.
3. File held too high 'results in blunt slow cutting edge, (Figure 17-B).
4. File held too low results in
thin;
quick dulling edge with hook, (Figure 17-C ).
Jointing
The chain is precision ground and has a standard joint of .025
inch.
Experience has
shown that .025 inch is best for average
conditions.
However, to suit particular cut-
ting conditions the joint can be changed as long as the joint heights are kept uniform
(lfigure 17).
If you change the joint use Gauge Part
No.
470163, available at your
servicing dealer, and proceed with caution since the chain can be easily damaged by
over filing.
In filing the runners,
maintain the rounded corners.
Improperly filed
runners will make some teeth cut more than others and the saw action will be rough
and tend to cut off line.
