MAINTENANCE
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,
misfeeds 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 18 - 19, page 19.
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.
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 18. No air should leak from the tool.
• Without pulling the trigger, press the workpiece con-
tact 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 oper-
ate.
• 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.
Rotate the selectable trigger knob on the trigger to
Contact Actuation operation, Position B, as shown in
figure 19.
• With the workpiece contact not engaged on the
workpiece, point the tool down and away. Pull the trig-
ger. 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.
REPLACING THE WIRE DEFLECTOR
See Figures 20 - 21, page 19.
Over time, the wire deflector will wear and should be re-
placed.
To remove the wire deflector:
Remove the pin that holds the deflector on the tool.
Using a 10 mm wrench, hold the nut in place. With a
5 mm hex key, loosen and remove the bolt.
Remove and discard the wire deflector.
NOTE: There is a gasket attached to the wire deflector
where the nut screws onto the bolt. The gasket should
not be removed from the wire deflector.
To attach a new wire deflector:
With the bolt inserted through the hole in the tool, install
the wire deflector gasket over the bolt.
Using a 5 mm hex key, hold the bolt in place. With a
10 mm wrench, tighten the nut securely. Do not over-
tighten.
Insert the long end of the wire deflector through the nose
piece as shown. Wrap it over so that the holes meet. Insert
the pin through both holes in the wire deflector and into
the hole in the tool. Make sure the pin is securely inserted
into the tool.
