WARNING:
When servicing use only identical replacement parts.
Use of any other parts could 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 perform-
ing 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 could 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.
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.
NOTICE:
Do not store tools in a cold weather environment to pre-
vent 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 undersize
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 pressure 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 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.
