5. Begin testing the depth of drive by driving a test fas-
tener into the same type of workpiece material used
for the actual job using an air pressure of 90-95 psi.
6. Raise or lower the air pressure to find the lowest
setting that will drive the fastener consistently. Do
not exceed 120 psi.
NOTE:
It may be possible to achieve the desired
depth with air pressure adjustments alone. If finer
adjustments are needed, use the depth of drive
adjustment.
7. To fine-tune the depth of drive, disconnect the air
supply and lay the tool on its side and point the nose
of the tool away from yourself and others. Remove
fastener strip. Turn the depth selector left or right to
increase or decrease the driving depth.
8. Reload fastener strip according to "Installing Fastener
Strips".
9. Drive a test fastener and repeat step 7 and 8 until
desired depth is reached.
REQUIRED DAILY TESTING
WARNING
To reduce the risk of injury to your-
self and others, test the tool before
beginning work each day or if the tool is dropped,
received a sharp blow, been run over, etc. Complete
the following checklist IN ORDER. If the tool does
not work as it should, contact a MILWAUKEE service
facility immediately.
Always point tool away from yourself and others.
1. Disconnect the air supply from the tool and remove
fastener strip.
2. Check all screws, bolts, nuts, and pins on the tool.
Any loose fasteners must be tightened.
3. Pull back the fastener pusher on the magazine (to
override the Reload Indicator) and press the work-
piece contact against a workpiece. It must move
smoothly.
4. With the workpiece contact pressed against the
workpiece, pull the trigger. It must move smoothly.
5. Connect the air supply (at 70 psi) to the tool. DO NOT
load a fastener strip.
6. Select the Single Sequential Actuation Operation. Air
must not leak from the tool.
Without pulling the trigger, pull back the fastener
pusher on the magazine (to override the Reload
Indicator) and press the workpiece contact against
a workpiece. The tool must not operate.
Holding the workpiece contact away from the work-
piece, pull back the fastener pusher on the magazine
(to override the Reload Indicator). Pull and hold the
trigger for 5 seconds. The tool must not operate.
Continue to pull and hold the trigger and push the
workpiece contact against a workpiece. The tool must
not operate.
Without pulling the trigger, pull back the fastener
pusher on the magazine (to override the Reload
Indicator) and press the workpiece contact against
a workpiece. Pull the trigger. The tool must operate.
Release the trigger. The driver must move up.
7. Select the Contact Actuation Operation.
Holding the workpiece contact away from the work-
piece, pull back the fastener pusher on the magazine
(to override the Reload Indicator) and pull the trigger.
The tool must not operate.
Continue to pull and hold the trigger and push the
workpiece contact against a workpiece. The tool must
operate.
8. If all previous tests work properly, set the tool for your
work. Select the operation and load fastener strips.
9. Set the depth of drive according to the "Setting the
Air Pressure and Depth of Drive" section.
10. If all tests operate properly, the tool is ready for use.
Repeat these tests before use each day or if the
tool is dropped, received a sharp blow, been run
over, jammed, etc.
MAINTENANCE
WARNING
To reduce the risk of injury, use only
identical replacement parts recom-
mended by the manufacturer. Tool service must be
performed only by qualified repair personnel. Al
-
ways wear safety goggles or glasses with side
shields when servicing tools. Disconnect tool from
air supply before servicing.
Cleaning
Clean dust and debris from tool vents. Keep tool handles
clean, dry and free of oil or grease. Use only mild soap
and a damp cloth to clean the tool, since certain clean-
ing agents and solvents are harmful to plastics and
other parts. Some of these include gasoline, turpentine,
lacquer thinner, paint thinner, chlorinated cleaning sol-
vents, ammonia and household detergents containing
ammonia. Never use flammable or combustible solvents
around tools.
Lubrication
Frequent, but not excessive, lubrication is required
for best performance. Oil added through the air line
connection will lubricate the internal parts. Do not use
detergent oil, WD-40, transmission fluid, motor oil, or
other lubricants not specifically designated as air tool
lubricant. These lubricants will cause accelerated wear
to the seals, o-rings and bumpers in the tool, resulting
in poor tool performance and frequent maintenance.
Cold Weather Operation
For cold weather operation, near and below freezing,
the moisture in the air line may freeze and prevent
tool operation. Use an air tool lubricant or permanent
antifreeze as a cold weather lubricant in the air line.
Do not store tools in a below-freezing environment. Ice
or frost could form on the tools' operating valves and
mechanisms, causing tool failure.
Air Supply-Pressure and Volume
Air volume is as important as air pressure. The air vol-
ume supplied to the tool may be inadequate because
of undersized 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 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.
