WARNING:

When servicing use only identical RIDGID® re- placement parts. Use of any other parts may cre- ate a hazard or cause product damage.

WARNING:

The tool 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, pe- troleum-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, spack- ling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chipsandgrindingsarehighlyabrasivetobearings,brushes, commutators, etc. Consequently, we do not recommended using this tool for extended work on these types of materi- als. 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 marked to comply with ANSI Z87.1during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.
