MAINTENANCE
WARNING:
When servicing use only identical replacement
parts. Use of any other parts could create a hazard
or cause product damage.
WARNING:
Always use eye protection with side shields which
is marked to comply with ANSI Z87.1 during power
tool operation or when blowing dust. 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 could
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 us-
ing compressed air.
LUBRICATION
All of the bearings in this product are lubricated with a suf-
ficient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
lubrication is required.
REPLACING THE GUARD
After extended use, the guard may wear and need replacing.
If you drop the grinder and damage the guard it may also
be necessary for you to replace it. Refer to
Installing the
Guard
earlier in this manual.
BRUSH REPLACEMENT
See Figure 10, page 14.
This product has externally accessible brush assemblies
that should be periodically checked for wear.
Unplug the angle grinder.
With a flat head screwdriver, remove the brush caps. The
brush assembly is spring loaded and will pop out when
you remove the brush cap.
Remove the brush assembly (brush and spring). 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.
Replace brush cap and tighten securely. Do not over-
tighten.
