Description: Ballistic NailScrew Driver: Model NO. NSDCN75 is a heavy duty, coil fed, pneumatic
nailer, using compressed air as power source. It is designed to drive 15° plastic sheet coil or 15° wire coil
with full round head Ballistic NailScrews® or nails 1-1/4” to 3” in length and 0.086˝ to 0.131˝ in diameter.
The NSDCN75 was specialty designed for UFO’s Ballistic NailScrew® program with the ease of
installation and durability in mind. The power to easily drive color matched Ballistic NailScrews® into
wood or composites into light gauge (12 to 20ga) steel frame and stop the drive when it is flush. This is
possible, but must be done a little differently that what you may be used to when you are attaching wood
to wood, so please follow these step by step rules when installing into steel.
•Consistent air pressure is the key to success. The closer to the compressor the better, but when
long runs of 3/8”air hose are necessary, the use of a surge tank will be necessary.
•Keep the pressure high--110 to120psi; the high velocity this creates is our friend. Please understand
this is where we are different than fastening to wood. Always be sure to test fire into the actual
material scraps, adjusting the depth of drive on the tool (See C Fig. 19) to compensate for the excess
pressure. Lower the pressure as a last resort and as little as necessary to get the job done.
• The NSDCN75 should be sequentially fired into steel. First, place the nose of the tool where you
want the fastener to be; this will depress the safety. Second, use the trigger to fire the tool in
this sequence each and every time. The tool must be placed squarely and very firmly; try not to
let the tool bounce off the work surface. This will give a more consistent drive and finished look.
• When you have a Ballistic NailScrew® that is too high or low, use a T15 Torx bit in a screw
driver or impact driver to adjust the NailScrew. Go very slowly to the desired depth. High rpm will
strip out the NailScrew. Go slow and you will be amazed at the results.
• This is very important! Please make sure the frames are set very firm--not springy or bouncy. If
the frame moves much, it will cause the NailScrews to be set very inconsistently.
The NSDCN75 has very low noise level, making it ideal for installing Ballistic NailScrews® for
Composite fencing to wood or steel, construction of pallets and crate assembly, composite or wood
deck construction, roof decks, sub-floor, sidewall sheathing, anywhere screws are being used and you
want to save time installing and still do a quality job etc. (see www.911-nails.com)

IMPORTANT! Upon receipt of your NailScrew® Driver, Read and
follow all safety rules and operating instructions.
Important Safety Rules
1. KEEP CHILDREN AWAY. All children should be kept away from the work area.
Do not allow them to handle the tool. Fig 1.
2. USE SAFETY GLASSES AND EAR PROTECTION. Air tool operators and
others in the work area should always wear safety glasses to prevent injury
from fasteners and flying debris during use and when loading and unloading
this tool. Wear ear protection to safeguard against hearing loss. (See fig 1.)
3. NEVER USE OXYGEN, COMBUSTIBLE FUELS OR ANY OTHER BOTTLED
GAS as a power source as it will cause explosion and serious personal
injury. (See Fig 2.)
4. DO NOT CONNECT TOOL TO COMPRESSED AIR WITH
PRESSURE EXCEEDING 120PSI.
5. DO NOT USE AN EXCESSIVELY LONG AIR HOSE in the working area as it
will create an operator tripping hazard. Secure all connections tightly.
6 .
CARRY TOOL ONLY BY THE HANDLE and keep finger off the trigger
pull. This will allow the safety yoke mechanism to prevent the
unintentional firing of fasteners.
Fig 3
7. KEEP THE TOOL POINTED AWAY FROM YOURSELF AND OTHERS at all
times. Keep hands and all body parts away from the nose area and rear area of
the tool to guard against possible injury.
8. DISCONNECT TOOL FROM AIR SUPPLY BEFORE LOADING
FASTENERS to prevent accidental fastener firing. (See Fig3.)
9. DO NOT DEPRESS TRIGGER OR SAFETY YOKE MECHANISM DURING FASTENER LOADING
to prevent the unintentional firing of a fastener that can cause personal injury.
10. DISCONNECT TOOL FROM AIR SUPPLY HOSE and disconnect from air compressor before
performing maintenance, altering accessories, or while not in operation.
11. DO NOT OPERATE ON SCAFFOLDINGS OR LADDERS, and do not work in airtight containers or vehicles.
12. DO NOT DRIVE FASTENERS CLOSE TO THE EDGE OF THE WORK PIECE. The work piece could
split, causing the fastener to fly free or ricochet, causing personal injury.
13. DO NOT DRIVE FASTENERS ON TOP OF OTHER FASTENERS or the fasteners can ricochet
causing personal injury.
14. NEVER USE A TOOL THAT IS LEAKING AIR, HAS MISSING OR DAMAGED PARTS, OR IS IN NEED
OF REPAIR. Make sure that all screws are securely tightened.
15. INSPECT DAILY FOR FREE MOVEMENT of trigger, safety mechanism and spring to insure safe and
proper operation of the tool.
16. ONLY USE PARTS AND ACCESSORIES RECOMMENDED BY THE MANUFACTURER.

POWER SOURCE
This tool is designed to operate on clean, dry, compressed air at regulated pressures between 70 and
120 PSI (4.9 and 8.3 bar) (Pounds per Square Inch). The preferred system would include a filter.
CAUTION: All line components (hoses, connectors, filters, regulators, etc.) must meet 150% of the
maximum system pressure. Please try to use a hose of ID 3/8” connecting nailer with compressor.
Disconnect tool from air supply before performing maintenance, clearing a jammed fastener, leaving
work area, moving tool to another location, or handing the tool to another person.
PREPARING THE TOOL BEFORE DRIVING
1. After reading and understanding this entire manual, connect tool to air supply. CAUTION: Keep tool
pointed away from you and others at all times. Always connect tool to air supply before loading
fasteners. Do not load fasteners with trigger or safety depressed. Always wear Z87 approved safety
glasses, and hearing protection when preparing or operating the tool. Never use a tool that leaks air
or needs repair.
2. Depress Handle and open the Latch. Rotate the Upper Nail Housing to the side of the Body.
3. The Adjuster Plate can be moved up and down by twisting the spindle and pulling up to decrease
or pushing down to increase to the length of nail (FIG.15) , the Adjuster Plate should be adjusted
correctly to the position indicated inside Lower Nail Housing. (FIG.16)
(FIG.15) (FIG16)
4. Place a coil of nails over the Lower Nail Housing. Uncoil enough nails to reach the Feed Paw and
place the second nail between the teeth on the Feed Paw.

5
5. Close the Nail Housing door and depress the Latch
6. Adjust directional EXHAUST deflector so that the exhaust air blast will be directed away from
the operator. Grasp the deflector and rotate it to the desired position for the current application.
RUBBER NO-MAR TIP:
ADJUSTING THE DRIVE DEPTH:
Driving depth will be adjusted by rolling the red wheel (FIG. 19) Test fire a fastener and check depth. If the
nail is driven too high, rotate the rolling wheel clockwise (right) if the nail is too deep rotate the rolling
wheel counter clockwise (left). Repeat this step until you reach desired depth. The red tear drop on the
trigger (FIG. 19) will allow you to change from sequential to bump fire. Reach behind the trigger and push
up (FIG. 20) this will allow raise the red tear drop then you can rotate the tear drop 180º so it will drop
back into trigger flush as shown in (FIG. 21).
(FIG. 19) (FIG. 20) (FIG. 21)
CLEARING A JAMMED FASTENER:
1.CAUTION: Disconnect tool from air supply.
2.Open latch, rotate lower housing and remove the nails of the lower housing.
3. Use a slender, soft steel rod to drive the drive blade to its upper most
position. Use needle nose pliers to remove the jammed fastener.
4.Follow instructions in PREPARING THE TOOL BEFORE DRIVING to reload fasteners.

6
Service advice:
1. Use clean, dry and regulated compressed air, 8 cfm at 5.0-7.5 bar (70-120psi) and 100-120psi at the
tool.
2. Never exceed the maximum and minimum pressures. Too low or too high pressure will cause noise,
increased wear or misfiring.
3. When connecting the air supply, always keep hands and body from the discharge area of the tool.
4. A filter-regulator-lubrication is required and should be located as close to the tool as possible (see
fig.4).
5. Keep the air filter clean. A dirty filter will reduce the air pressure to the tool, causing a reduction in
power and efficiency.
6. For better performance, install a quick connector in your tool and quick coupler on the hose, if possible.
7. Make sure that all connections in the air supply system are sealed to prevent air loss.
