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.
