WARNING: When servicing, use only identical
replacement parts. Use of any other part may create
a hazard or cause product damage.
WARNING: Always wear safety goggles or safety
glasses with side shields during power tool operation
or when blowing dust. If operation is dusty, also wear
a dust mask.
GENERAL
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, carbon dust, etc.
,_ WARNING: Do not at any time let brake fluids,
gasoline, petroleum-based products, penetrating
oils, etc. come in contact with plastic parts. Chemi-
cals can damage, weaken or destroy plastic which
may 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, com-
mutators, etc. Consequently, we do not recommend using
this tool for extended work on these types of materials. How-
ever, 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 suffi-
cient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
lubrication is required.
_IL WARNING: To ensure safety and reliability, all
repairs -- with the exception of the externally acces-
sible brushes -- should be performed by a qualified
service technician at a Sears store to avoid risk of
personal injury.
BRUSH REPLACEMENT
See Figure 48.
Your saw has externally accessible brush assemblies that
should be periodically checked for wear.
Proceed as follows when replacement is required:
[] Unplug the saw.
_1_ WARNING: Failure to unplug the saw could result in
accidental starting causing serious injury.
[] 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.
