MAINTENANCE
WARNING:
When servicing use only identical RIDGID
replacement parts. Use of any other parts 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 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.
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 recommended 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 sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrication
is required.
REPLACING THE GUARD
See Figures 9 - 10.
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.
To replace the guard:
� Unplug the grinder.
WARNING:
Failure to unplug the grinder could result in
accidental starting causing serious injury.
� Depress spindle lock button and rotate clamp nut until
spindle locks.
