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. 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 See Figure 10, page 14. Unplug the sander. WARNING: 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.
