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 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 6 - 8, page 17.
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.
Rotate the selectable trigger knob on the trigger to Single
Sequential Actuation operation, Position A, as shown in
Figure 6. No air should leak from the tool.
• Without pulling the trigger, press the workpiece
contact against a workpiece several times. The tool
must not operate.
• 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. The tool must operate.
• With the workpiece contact still depressed, release
the trigger. The driver must return to its up position.
Rotate the selectable trigger knob on the trigger to
Contact Actuation operation, Position B, as shown in
Figure 6.
• With the workpiece contact not engaged on the
workpiece, point the tool down and away. Pull the
trigger. The tool must not operate.
• Keeping the trigger fully depressed, push the workpiece
contact against a workpiece. The tool must operate.
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.
