MAINTENANCE

WARNING:
When servicing, use only identical replacement
parts. Use of any other parts may create a hazard
or cause product damage.
WARNING:
Always wear eye protection with side shields
marked to comply with ANSI Z87.1 during product
operation. If operation is dusty, also wear a dust
mask.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline,
petroleum-based products, penetrating oils, etc.,
come in contact with plastic parts. Chemicals can
damage, weaken or destroy plastic which may
result in serious personal injury.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. After extended use, clean the
rails, table tubes, and bevel sliding surfaces so the table will
slide smoothly. Lubricate with light oil (e.g., WD40).

BRUSH REPLACEMENT

See Figure 45.
The saw has externally accessible brush assemblies that
should be periodically checked for wear.
Proceed as follows when replacement is required:
 Unplug the saw.
 Remove brush cap with a screwdriver. Brush assembly is
spring loaded and will pop out when you remove brush
cap.
 Remove brush assembly.
 Check for wear. Replace both brushes when either has
less than 1/4 in. length of carbon remaining. Do not
replace one side without replacing the other.
 Reassemble using new brush assemblies. Make sure
curvature of brush matches curvature of motor and that
brush moves freely in brush tube.
 Make sure brush cap is oriented correctly (straight) and
replace.
 Tighten brush cap securely. Do not overtighten.

CLEANING THE RAILS

During use, the rails will become dirty preventing the table
rollers from sliding smoothly. It is important to clean the rails
often. Lubricate with light oil (e.g., WD40).
