Sharpening the Chain
When the cutting edges of the blade
become dull, they can be re-sharpened
with a few strokes of a file.
In order to keep the blade in balance, all
cutting edges must be sharpened equally.
In addition, inspect the chain for correct
adjustment (more frequently with a new
chain). The chain should feel snug but
still pull freely. Refer to the section on
“Adjusting the Chain” for adjustment
procedures.
IMPORTANT!
File all cutters to the same angle and
depth! Unequal filing may cause the saw
to vibrate or cut erratically!
NOTE:
For consistent ling angles, use a ling
guide
Using a 4.5 mm round file, sharpen all
cutters to a 30° angle.
1.
Using a depth gauge
joiner.
Using a at le
to round the
front corner on a
depth gauge.
Using a ling
gauge.
As required, lower the depth gauges to
a height of 0.6 mm.
After all depth gauges have been
adjusted, use a flat file to round each
depth gauge leading edge to its original
curvature and angle.

Correct Filing Technique
Filing Problems
Top plate
angle less than
recommended
Backslope
on side plate
cutting edge
Top plate angle
more than
recommended
Hook in side
plate cutting
edge
Cause
File held at less than
recommended angle.
Result
Slow cutting. Requires extra
effort to cut.
Remedy
File cutters to recommended
angle.
Cause
File held too low or the le
was too small.
Result
Rough cutting. Chain grabs.
Cutters dull quickly or won’t
hold a cutting edge.
Remedy
Check le size. File cutters to
recommended angle.
Cause
File held too high or the le
was too large.
Result
Cutters won’t feed into
wood. Slow cutting. Must
force chain to cut. Causes
excessive bottom wear.
Remedy
File cutters at recommended
angle. Check le size.
Cause
File held at more than
recommended angle.
Result
Cutting angle is very sharp
but will dull fast. Cutting
action rough and erratic.
Remedy
File cutters to recommended
angle.
Low depth
gauge
High depth
gauge
Cause
Wrong gauge setting or no
gauge used.
Result
Rough cutting. Chain grabs.
Saw won’t pull chain through
wood. Excessive wear on the
cutter heel.
Remedy
If depth gauges are too
low, the chain is no longer
serviceable.
Cause
Depth gauge never led.
Result
Slow cutting. Must force
chain to cut. Will cause
excessive wear on the cutter
heel.
Remedy
Lower gauges to
recommended setting.

All cutting edges must be sharpened equally
After all cutters are sharpened, use
a depth gauge joiner to measure the
height of each depth gauge.
