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 eye protection with side shields
marked to comply with ANSI Z87.1. Failure to do
so could result in objects being thrown into your
eyes, resulting in possible serious injury.
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, 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. They contain
chemicals that can damage, weaken, or destroy
plastic.
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,
commutators, etc. Consequently, we do not recommended
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 tool 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 the manufacturer or an authorized service
center in order to avoid a safety hazard.
BRUSH REPLACEMENT
See Figure 21, page 15.
This product has externally accessible brush assemblies
that should be periodically checked for wear.
 Unplug the tool.
 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.
NOTE: When the brushes wear down to a predetermined
level, the tool automatically switches off, ruling out the
possibility of damage to the armature.
 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
overtighten.
