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
CORRECT
Side Plate
Filing Angle
80°
• 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.

Flat File
Use a flat file and a depth gauge jointer to lower all
gauges uniformly. Depth gauge jointers are available
in .020 in. to .035 in. Use a .025 in. 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, flip 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 pro-
cess 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 lubricating hole. Turn the guide bar and check
that the lubrication holes and bar rails 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.
To reduce the risk of personal in-
WARNING
jury and damage, never immerse
your tool, battery pack or charger in liquid or
allow a liquid to flow inside them.
Clean dust and debris from vents. Keep handles
clean, dry and free of oil or grease. Use only mild
soap and a damp cloth to clean, since certain clean-
ing agents and solvents are harmful to plastics and
other insulated parts. Some of these include gasoline,
turpentine, lacquer thinner, paint thinner, chlorinated
cleaning solvents, ammonia and household deter-
gents containing ammonia. Never use flammable or
combustible solvents around tools.
For repairs, return the tool, battery pack and charger
to the nearest authorized service center.
