Be careful to le all cutters to the specied angles and
to the same length, as fast cutting can be obtained only
when all cutters are uniform.
• Wear gloves for protection. Properly tension the chain
prior to sharpening. Refer to Chain Tension section
earlier in this manual. Do all of your ling at the mid-
point of the bar.
Left Hand Cutters
Right Hand Cutters
• Use a 11/64" (4.4 mm) diameter round le and holder.
• Keep the le level with the top plate of the tooth. Do
not let the le dip or rock.
• Using light but rm pressure, stroke towards the front
corner of the tooth.
• Lift le away from the steel on each return stroke.
• Put a few rm strokes on every tooth. File all left hand
cutters in one direction. Then move to the other side
and le the right hand cutters in the opposite direc-
tion. Occasionally remove lings from the le with a
wire brush.

INCORRECT
Top Plate Filing Angle
• CORRECT 30° - File holders are marked with guide
marks to align le properly to produce correct top
plate angle.
• LESS THAN 30° - For Cross Cutting.
• MORE THAN 30° - Feathered Edge Dulls Quickly.

80°
INCORRECT
Side Plate Filing Angle
• CORRECT - 80° Produced automatically if correct
diameter le is used in le holder.
• HOOK - “Grabs” and dulls quickly. Increases po-
tential of KICKBACK. Results from using a le with
diameter too small, or le held too low.
• BACKWARD SLOPE - Needs too much feed pres-
sure, causes excessive wear to bar and chain.
Results from using a le with diameter too large, or
le held too high.
Depth Gauge Clearance
• The depth gauge should be maintained at a clear-
ance of .025". Use a depth gauge tool for checking
the depth gauge clearances.
• Every time the chain is led, check the depth gauge
clearance.
Flat File
Depth Gauge Jointer
Use a at le and a depth gauge jointer to lower all
gauges uniformly. Depth gauge jointers are available
in 0.02" to .035" Use a .025" depth gauge jointer.
After lowering each depth gauge, restore original
shape by rounding the front. Be careful not to damage
adjoining drive links with the
edge of the le.
Depth gauges must be ad-
justed with the at le in the
same direction the adjoin-
ing cutter was led with the
round le. Use care not to
contact cutter face with at
file when adjusting depth
gauges.
Guide Bar Maintenance
When the guide bar shows signs of wear, ip the guide
bar from bottom to top on the saw to distribute the wear
for maximum bar life. The bar should be cleaned every
day of use and checked for wear and damage.
Feathering or burring of the bar rails is a normal process
of bar wear. Such faults should be smoothed with a le
as soon as they occur.
