MAINTENANCE
WARNING:
When servicing use only identical RIDGID
replacement parts. Use of any other parts may
create a hazard or cause product damage.
WARNING:
The sander should never be connected to a power
supply when you are assembling parts, making
adjustments, cleaning, performing maintenance, or
when the tool is not in use. Disconnecting the tool
will prevent accidental starting that could cause
serious injury.
GENERAL
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 incontact with plastic parts. They contain
chemicalsthat 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.
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.
