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.
BRUSH REPLACEMENT

WARNING:
Failure to unplug the tool could result in accidental 
starting causing possible serious injury.

Check for wear. Replace both brush assemblies 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.
