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
appropriate size wrench.
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.
While the tool is not loaded, connect the appropriate air
supply (at 70 psi) to the tool.
Without pulling the trigger, press the workpiece contact
against a workpiece several times. The tool must not
operate. No air should leak from the tool.
With the workpiece contact not engaged on the
workpiece, point the tool down and away and pull the
trigger several times. Hold the trigger in this position for
a minimum of 5 seconds. The tool must not operate.
Press the workpiece contact firmly against the
workpiece. Pull the trigger. The tool must operate.
With the workpiece contact still depressed, release the
trigger. The driver must return to its up position.
If the tool successfully meets all the requirements in this
checklist, it is ready for use. 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.
WARNING:
When servicing use only identical 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.
