Maintenance; General Maintenance - RIDGID R138HPA Operator's Manual

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.
LUBRICATION
Frequent, but not excessive, lubrication is required for
best performance. Oil for pneumatic fastening tools added
through the air line connection will lubricate the internal parts.
Do not use detergent oil or additives as these lubricants will
cause accelerated wear to the seals and bumpers in the
tool, resulting in poor tool performance and frequent tool
maintenance.
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.
REqUIRED DAILY CHECKLIST
 Disconnect the air supply from the tool and remove all
fasteners.
 Check all screws, nuts, bolts, and pins on the tool. If any
of these are loose, they must be tightened with the ap-
propriate size wrench.
 Pull the secondary and primary triggers. Cycle them sev-
eral times to ensure that they function smoothly without
binding.
 While the tool is not loaded, connect the appropriate air
supply (at 70 psi) to the tool. No air should leak from the
tool.
 Place the nose of the tool on the workpiece. Attempt to
pull the primary trigger without first pulling the second-
ary trigger. The primary trigger should not disengage the
secondary trigger, and the unit should not cycle. Pull the
primary trigger in this manner several times.
 Place the nose of the tool on the workpiece. Pull the
secondary trigger and hold. Then pull the primary trigger
several times. The tool must operate properly.
 If the tool successfully meets all the requirements in this
checklist, it is ready for use.
