Maintenance; Lubrication - RIDGID R138HPF Manuel D'utilisation

MAINTENANCE

WARNING:
When servicing use only identical replacement
parts. Use of any other parts may create a hazard
or cause product damage.
WARNING:
Always wear eye protection with side shields
marked to comply with ANSI Z87.1. Failure to do
so could result in objects being thrown into your
eyes resulting in possible serious injury.
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

The cylinder, o-ring, and piston ring in this tool are lubricated
with a sufficient amount of high grade lubricant for the life
of the unit under normal operating conditions. No further
lubrication is required. However, periodically adding oil is
recommended and can flush out possible debris inside the
tool.
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.
NOTICE:
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 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 contain-
ing 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
appropriate size wrench.
 Pull the secondary and primary triggers. Cycle them
several 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 secondary
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.
