Left Hand Cutters
Right Hand Cutters
• Use a 5/32" diameter round file and holder.
• Keep the file level with the top plate of the tooth. Do
not let the file dip or rock.
• Using light but firm pressure, stroke towards the
front corner of the tooth.
• Lift file away from the steel on each return stroke.
• Put a few firm strokes on every tooth. File all left
hand cutters in one direction. Then move to the other
side and file the right hand cutters in the opposite
direction. Occasionally remove filings from the file
with a wire brush.
Top Plate Filing Angle
CORRECT
Top Plate Filing Angle
30°
• CORRECT 30° - File holders are marked with guide
marks to align file properly to produce correct top
plate angle.
• LESS THAN 30° - For Cross Cutting.
• MORE THAN 30° - Feathered Edge Dulls Quickly.
Side Plate Angle

Hook
Slope
• CORRECT - 80° Produced automatically if correct
diameter file is used in file holder.
• HOOK - "Grabs" and dulls quickly. Increases po-
tential of KICKBACK. Results from using a file with
diameter too small, or file held too low.
• BACKWARD SLOPE - Needs too much feed pres-
sure, causes excessive wear to bar and chain.
Results from using a file with diameter too large, or
file held too high.
Depth Gauge Clearance
• The depth gauge should be maintained at a clear-
ance of .025 in. Use a depth gauge tool for checking
the depth gauge clearances.
• Every time the chain is filed, check the depth gauge
clearance.
Depth Gauge Jointer
Use a flat file and a depth gauge jointer to lower all
gauges uniformly. Depth gauge jointers are available
in .020" 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 file.
Depth gauges must be ad-
justed with the flat file in the
same direction the adjoin-
ing cutter was filed with the
round file. Use care not to contact cutter face with
flat file when adjusting depth gauges.
Guide Bar Maintenance
When the guide bar shows signs of wear, reverse it
on the tool 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 file as soon as they occur.
A bar with any of the following faults should be
replaced.
• Wear inside the bar rails which permits the chain to
lay over sideways.
• Bent guide bar.
• Cracked or broken rails.
• Spread rails.
Lubricate guide bars with a sprocket at their tip weekly.
Using a grease syringe, lubricate weekly in the lubri-
cating hole. Turn the guide bar and check that the lubri-
cation holes and chain groove are free from impurities.
NOTE: Do not replace the screw with an ordinary
screw. Use only identical replacement parts from the
manufacturer when replacing parts.
