The DWFP12569 requires 3.52 cubic feet per minute (100 liters per minute) of free air to operate at the rate of 60 fasteners per minute, at 80 p.s.i. (5.6kg / cm2) .Take the actual rate at which the tool will be run to determine the amount of air required. For instance, if your fastener usage averages 30 fasteners per minute, you need 50% of the tool's c.f.m. of free air which is required to operate the tool at 60 fasteners per minute.

Safety Information

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:

ANSI Z87.1 eye protection (CAN/CSA Z94.3)
ANSI S12.6 (S3.19) hearing protection,
- NIOSH/OSHA/MSHA respiratory protection.

WARNING: Some dust created by power sanding, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,
  crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful chemicals.

WARNING: Always wear proper personal hearing protection that conforms to ANSI S12.6 (S3.19)

during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss.

WARNING: (Air and Supply)

Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as tool may explode, possibly causing injury.

• Do not use supply sources which can potentially exceed 200 P.S.I.G. (14kg/cm2) as tool may burst, possibly causing injury.
• The connector on the tool must not hold pressure when air supply is disconnected. If a wrong fitting is used, the tool can remain charged with air after disconnecting and thus will be able to drive a fastener even after the air line is disconnected possibly causing injury.
• Do not pull trigger or depress contact arm while connected to the air supply as the tool may cycle, possibly causing injury.
• Always disconnect air supply: 1.) Before making adjustments; 2.) When servicing the tool; 3.) When clearing a jam; 4.) When tool is not in use; 5.) When moving to a different work area, as accidental actuation may occur, possibly causing injury.

• Do not pull the trigger or depress the trip as accidental actuation may occur, possibly causing injury.

WARNING: When operating the tool: Always handle the tool with care.

• Never engage in horseplay;
• Never pull the trigger unless nose is directed toward the work;

• Keep others a safe distance from the tool while tool is in operation as accidental actuation may occur, possibly causing injury.

• The operator must not hold the trigger pulled on contact arm tools except during fastening operation as serious injury could result if the trip accidentally contacted someone or something, causing the tool to cycle.

• Keep hands and body away from the discharge area of the tool. A contact arm tool may bounce from the recoil of driving a fastener and an unwanted second fastener may be driven possibly causing injury.
• Check operation of the contact arm mechanism frequently. Do not use the tool if the arm is not working correctly as accidental driving of a fastener may result. Do not interfere with the proper operation of the contact arm mechanism.
• Do not drive fasteners on top of other fasteners or with the tool at an overly steep angle as this may cause deflection of fasteners which could cause injury.
• Do not drive fasteners close to the edge of the work piece as the wood may split, allowing the fastener to be deflected possibly causing injury.
• This nailer produces SPARKS during operation. NEVER use the nailer near flammable substances, gases or vapors including lacquer, paint, benzine, thinner, gasoline, adhesives, mastics, glues or any other material that is -- or the vapors, fumes or byproducts of which are -- flammable, combustible or explosive.

Refer to Figure A at the beginning of this manual for a complete list of components.

Intended Use

Your 2-N-1TM Flooring Nailer is designed for professional installation of hardwood flooring.

CAUTION: Your flooring nailer can be used to install finished flooring however caution must be used to ensure that the finish is not damaged by the tool. It is recommended that the tool be tested on a sample section to be certain that the tool and technique of use do not leave marks on the finish. This procedure should be followed before each job due to variations in flooring and tool condition.

Your nailer is a professional power tool.

DO NOT let children come into contact with the tool.

Supervision is required when inexperienced operators use this tool.

Adjustments and Usage Prep

Air Supply and Connections

WARNING: Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as tool may explode, possibly causing injury.

Fittings

Install a male plug on the tool which is free flowing and which will release air pressure from the tool when disconnected from the supply source.

Hoses

Air hoses should have a minimum of 150 p.s.i. (10.6 kg/cm2) working pressure rating or 150 percent of the maximum pressure that could be produced in the air system. The supply hose should contain a fitting that will provide "quick disconnecting" from the male plug? on the tool.

Supply Source

Use only clean regulated compressed air as a power source for this tool. NEVER USE OXYGEN, COMBUSTIBLE GASES, OR BOTTLED GASES, AS A POWER SOURCE FOR THIS TOOL AS TOOL MAY EXPLODE.

Regulator

A pressure regulator with an operating pressure of 0 - 125 p.s.i. (0 - 8.79 KG/CM2) is required to control the operat iing pressure for safe operation of this tool. Do not connect this tool to air pressure which can potentially exceed 200 p.s.i. (14 KG/CM2) as tool may fracture or burst, possibly causing injury.

Operating Pressure

Do not exceed recommended maximum operating pressure as tool wear will be greatly increased. The air supply must be capable of maintaining the operating pressure at the tool. Pressure drops in the air supply can reduce the tool's driving power. Refer to Tool Specifications for setting the correct operating pressure for the tool.

Filter

Dirt and water in the air supply are major causes of wear in pneumatic tools. A filter will help to get the best performance and minimum wear from the tool. The filter must have adequate flow capacity for the specific installation. The filter has to be kept clean to be effective in providing clean compressed air to the tool. Consult the manufacturer's instructions on proper maintenance of your filter. A dirty and clogged filter will cause a pressure drop which will reduce the tool's performance.

Lubrication

Frequent, but not excessive, lubrication is required for best performance. Use Air Tool Lubricant, Mobil Velocite #10, or equivalent. 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. Only a few drops of oil at a time is necessary inserted into air fitting opening. Too much oil will only collect inside the tool and will be noticeable in the exhaust cycle.

Setup (Fig. B)

Your flooring nailer was designed to install 1/2'' to 3/4'' tongue and groove hardwood flooring. The tool is factory set for 3/4'' flooring. Two additional foot plates are included with this tool to accommodate 1/2'' and 5/8'' flooring.

Flooring products will vary and the user must ensure the tool is properly adjusted each time flooring is being installed. Dimensions listed on the footplates are suggestions.Test fastener placement on scrap pieces of wood before installing floor.

Fig.B

To change footplates:

1. Remove the screws 8.
2. Change to desired plate.
3. Replace the screws.

NOTE: Adjust air pressure until desired fastener penetration is achieved. (Fig. F)

Fig. F
Under Driven Fastener

Properly Driven Fastener

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 winter formula 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.

Maintenance

Cleaning

WARNING: Blow dirt and dust out of all air vents with dry air at least once a week. To minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when performing this.

WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the plastic materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

Replacement Parts

DeWALT replacement parts are recommended. Do not use modified parts or parts which will not give equivalent performance to the original equipment.

To Replace Piston

1. Insert the flats on the lower end of the driver piston stem carefully into the end of piston and plunger wrench, BC1009.

2. Using another special wrench, BC1009, or another wrench of the proper size, unscrew the plunger from the upper end of the stem. After this is done, it will be possible to lift the poppet off the stem.

3. Place the special wrench, BC1009, down over the piston stem onto the driver piston, locking the piston ears in the slots in the wrench. Unscrew the piston from the stem.

To Replace Driver

1. It is not necessary to disassemble the piston-poppetdriver assembly to replace the driver. Pull the poppet up on the driver piston stem as far as it will go.
2. Insert special wrench, BC1009, over the driver piston, locking the piston ears in the slots in the wrench. Unscrew the piston from threaded portion of the stem.
3. To remove the driver blade from the piston stem, push the driver blade pin out of the stem. This will release the blade.
4. Insert new driver blade into the slot in the end of the driver piston stem and assemble the driver blade pin. Test the side play in the driver blade by grasping the driver piston stem in one hand and the blade in the other and moving the blade sideways in alignment with the slot in the stem. There should be a small amount of side play in the blade. This is necessary to take care of any slight misalignment between the blade and guide in the nose. If there is no side play, the blade should be removed and the top (pin end) just barely dressed off with a stone. It is not necessary to do more than smooth off the top to get the necessary side play. Do not grind. Reinsert the blade and pin in the stem and test for side play once more. Repeat as necessary to get this small amount of side play. Carefully examine the large threaded portion of the piston stem. A nylon lock can be seen imbedded in a recessed hole in the stem. It is very important that this nylon lock can be replaced when its locking efficiency has been reduced through several disassemblies of the piston. It is necessary to use the sharp point of a knife, or some such instrument, to remove this nylon lock. Insert a new one by setting it into the recessed hole in the stem, and tapping it gently until firmly seated. Reverse these instructions to reassemble.
5. Assemble plunger flush with end of piston stem.

Assembly Procedure For Seals

When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker "O"-LUBE or equivalent on all "O"-rings. Coat each "O"-ring with "O"-LUBE before assembling. Use a small amount of oil on all moving surfaces and pivots. After reassembly add a few drops of DEWALT Air Tool Lubricant through the air line fitting before testing.

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 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, swivel fittings, low points containing water and anything else that would prevent full volume flow of air to the tool.
