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 potential
of KICKBACK. Results from using a file with diameter
too small, or file held too low.
• BACKWARD SLOPE - Needs too much feed pressure,
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 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 adjoining

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 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/
groove which permits the chain to lay over sideways.
• Bent guide bar.
• Cracked or broken rails/guide bar groove.
• Spread rails.
Lubricate guide bars with a sprocket at their tip
weekly. Using a grease syringe, lubricate weekly in
the lubricating hole, located under chain cover. Turn
the guide bar and check that the lubrication holes and
bar rails are free from impurities.
To reduce the risk of personal in-

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 any vents. Keep tool
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.
