Maintenance - RIDGID R88040 Operator's Manual

OPERATION
NOTE: Heavy pressure will decrease the grinder's speed and
put a strain on the motor. Normally the weight of the tool
alone is adequate for most grinding jobs. Use light pressure
when grinding jagged edges or loose bolts where there is the
potential for the grinder to snag on the metal edge.

MAINTENANCE

WARNING:
When servicing, use only identical replacement
parts. Use of any other part could create a hazard
or cause product damage.
WARNING:
Always wear eye protection with side shields
marked to comply with ANSI Z87.1, along with
hearing protection. Failure to do so could result
in objects being thrown into your eyes and other
possible serious injuries.
WARNING:
To avoid serious personal injury, always Remove
battery packs from the tool when cleaning,
performing any maintenance, or when storing the
tool.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and can be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.

 Use just enough pressure to keep the grinder from
chattering or bouncing. When too much pressure is
applied and not relieved, an overload condition may result,
causing the tool to automatically shut off.
 Lift the grinder away from the workpiece before turning
the grinder off.
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 could
result in serious personal injury.
