MAINTENANCE
WARNING:
When servicing use only identical Ridgid replace- ment parts. Use of any other parts may create a hazard or cause product damage.
WARNING:
The angle grinder should never be connected to a power supply when you are assembling parts, making adjustments, cleaning, performing main- tenance, or when the tool is not in use. Discon- necting the tool will prevent accidental starting that could cause serious injury.

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.
