General Maintenance, Lubrication

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 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.

GENERAL MAINTENANCE

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, dust, oil, grease, etc.

WARNING:

Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken, or destroy plastic which may result in serious personal injury.

Electric tools used on fiberglass material, wallboard, spack- ling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, com- mutators, etc. Consequently, we do not recommended using this tool for extended work on these types of materials. How- ever, 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 unit under normal operating conditions. Therefore, no further lubrication is required.

REPLACING THE GUARD

See Figures 9 - 10.

After extended use, the guard may wear and need replacing. If you drop the grinder and damage the guard it may also be necessary for you to replace it.

To replace the guard: � Unplug the grinder.

WARNING:

Failure to unplug the grinder could result in accidental starting causing serious injury.

� Depress spindle lock button and rotate clamp nut until spindle locks.
