Maintenance - RIDGID R2501 Operator's Manual

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.
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 in contact with plastic parts. They contain
chemicals that can damage, weaken, or destroy
plastic.

FRENCH AND SPANISH LANGUAGE SECTIONS.
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.
BRUSH REPLACEMENT

Failure to unplug the tool could result in accidental
starting causing possible serious injury.
 Remove screws (3) from top cover of sander.
 Remove top cover.
 Remove clamp screws (2).
 Remove brush tube clamps (2).
 Disconnect red and black lead terminals from brush
tubes.
 Remove brush assemblies (2).
 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.
 Reassemble by reversing the steps listed above.
 Tighten all screws securely. Do not over tighten.
