MAINTENANCE
LUBRICATION
All of the bearings in this product are lubricated with a
sufficient amount of high grade lubricant for the life of the
unit under normal operating conditions. Therefore, no further
lubrication is required.
POWER SUPPLY CORD REPLACEMENT
If replacement of the power supply cord is necessary, this
must be done by an authorized service center in order to
avoid a safety hazard.
BRUSH REPLACEMENT
See Figure 16, page 15.
NOTE: This saw is equipped with two externally accessible
brushes located on either side of the saw housing.

Unplug the saw.
WARNING:
Failure to unplug the tool could result in accidental start-
ing causing possible serious injury.
 Remove brush caps using a screwdriver.
 Remove brush assemblies.
 Check for wear. Replace both brush assemblies when
either has less than 1/4 in. length of carbon remaining.
NOTE: 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.
 Reassemble by reversing the steps listed above.
 Tighten brush caps securely. Do not over tighten.
WHEEL MAINTENANCE
If wheel cutting ability deteriorates or becomes slow, the wheel
may need resurfacing. Cutting a brick paver will resurface
the wheel and improve wheel cutting ability.
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts can 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 can result in serious personal injury.
Electric tools used on fiberglass material, wallboard, spack-
ling compounds, or plaster are subject to accelerated wear
and possible premature failure because the fiberglass chips
and grindings are highly abrasive to bearings, brushes,
commutators, etc. Consequently, we do not recommend
using this product for extended work on these types
of materials. However, if you do work with any of these
materials, it is extremely important to clean the product
using compressed air.
