MAINTENANCE
WARNING:
When servicing use only identical RIDGID® replace- ment parts. Use of any other parts may create a hazard or cause product damage.
Brush Replacement
See Figure 11.
1. Unplug your sander.
WARNING:
The random orbit sander should never be connected to a power supply when you are assembling parts, making adjustments, cleaning, performing mainte- nance, 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, petro-
Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiber- glass 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.
Bearing Lubrication
All of the bearings in this tool are lubricated with a suffi- cient amount of high grade lubricant for the life of the tool under normal operating conditions. Therefore, no further lubrication is required.
WARNING:
Failure to unplug the tool could result in accidental starting causing possible serious injury.
