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.
WARNING:
Disconnect the tool from the air supply before
performing maintenance. Failure to do so could
result in serious personal injury.
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.
COLD WEATHER OPERATION
For cold weather operation, near and below freezing, the
moisture in the air line may freeze and prevent tool operation.
We recommend the use of air tool lubricant or permanent
antifreeze (ethylene glycol) as a cold weather lubricant.
CAUTION:
Do not store tools in a cold weather environment
to prevent frost or ice formation on the tools’
operating valves and mechanisms that could cause
tool failure.
NOTE: Some commercial air line drying liquids are harmful
to “O” rings and seals. Do not use these low temperature
air dryers without checking compatibility.
AIR SUPPLY PRESSURE AND VOLUME
Air volume is as important as air pressure. The air volume
supplied to the tool may be inadequate because of under-
size fittings and hoses, or from the effects of dirt and water
in the system. Restricted air flow will prevent the tool from
receiving an adequate volume of air, even though the pres-
sure reading is high. The results will be a slow operation,
misfeeds or reduced driving power. Before evaluating tool
problems for these symptoms, trace the air supply from
the tool to the supply source for restrictive connectors, low
points containing water and anything else that would prevent
full volume flow of air to the tool.
