MAINTENANCE
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
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. Therefore, no
further lubrication is required.
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 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
See Figures 7 - 9, page 14.
 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.
 If your tool is equipped with a dry-fire lockout mechanism,
then you will need to disengage this feature by opening
the magazine slightly or retracting the bypass pusher.
With the dry-fire lockout disengaged, perform the steps
below:
 Press the workpiece contact against a workpiece to
ensure that it moves smoothly.
 With the workpiece contact depressed, pull the trigger.
The trigger should move smoothly, without binding.
 Select the single sequential actuation mode ( ).
 While the tool is not loaded, connect the appropriate air
supply (at 70 psi) to the tool.
 Begin inspection:
• Without pulling the trigger, press the workpiece
contact against a workpiece several times. The tool
must not actuate.
• With the workpiece contact not engaged on the
workpiece, point the tool down and away in a safe
direction and pull the trigger several times. Hold the
trigger in this position for a minimum of 5 seconds.
The tool must not actuate.
• Press the workpiece contact firmly against the
workpiece and pull the trigger. The tool must actuate.
• With the workpiece contact still depressed, release
the trigger. The driver must return to its up position.
 Select the contact actuation mode (
 Begin inspection:
• With the workpiece contact not engaged on the
workpiece, point the tool down and away in a safe
direction. Pull the trigger. The tool must not actuate.
• Fully depress the trigger and push the workpiece
contact against a workpiece. The tool must actuate.
 Disconnect the air supply from the tool.
 If the tool successfully meets all the requirements in this
checklist, it is ready for use. Set the trigger on the tool
to operate in the manner that best fits your application.
Load the proper fasteners for the desired application.
 Set the depth of drive according to the Drive Depth
Adjustment section in this manual. Repeat this checklist
before using the tool each day, or if the tool is dropped
or damaged in any way.
