To reduce the risk of injury, turn unit off and
disconnect it from power source before cleaning or servicing,
before installing and removing accessories, before adjusting
when making repairs. An accidental start-up can cause serious
injury.
KEEP MACHINE CLEAN
Periodically blow out all air passages with
dry compressed air. All plastic parts should be cleaned with a
soft damp cloth. NEVER use solvents to clean plastic parts.
They could possibly dissolve or otherwise damage the material.
Wear certified safety equipment for eye, hearing and
respiratory protection while using compressed air.
Empty dust bag frequently.
When servicing, use only identical replacement parts. Use of
any other parts may create a hazard or cause product damage.
GENERAL MAINTENANCE
NEVER use 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.
BRUSH REPLACEMENT
The motor on this saw features externally accessible brush
assemblies that should be periodically checked for wear. If the
brushes need to be replaced, see Figure 41 and proceed as
follows:
1.
Unplug the saw.
Failure to unplug the saw could result in
accidental starting causing serious personal injury.
2.
Loosen Screws
A
Using a flathead screwdriver carefully remove the brush
cap
.
B
NOTE: Remove the cap slowly. The brush assembly is spring-
loaded and will pop out once the cap is removed. If machine
was recently operated, use caution when removing the carbon
brushed as they may be hot.
3.
Remove brush assembly
4.
Inspect both brushes. If either has less than 1/4 inch
length of carbon remaining, both brushes should be
replaced.
NOTE: DO NOT replace one side without replacing the other.
5.
Insert both brushes into the brush tubes
sure the curvature of the brushes matches curvature of
motor. Brush assembly should move freely within the
tube.
6.
Carefully replace the brush cap, ensuring that the brush
cap is clean and properly aligned so the threads don't
strip.
7.
Tighten brush cap securely. DO NOT over-tighten.

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.
Electric tools used on fiberglass material, wallboard,
spackling compounds, or plaster are subject to accelerated
wear and possible premature failure because the fiberglass
chips and grindings are highly abrasive to bearings, brushes,
commutator, etc. Consequently, we DO NOT recommend
using this tool 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 tool using compressed air.
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. Therefore, no further lubrication
is required.
