INTENDED USE

This DWMIIIFS Flooring Tool is intended for use by construction professionals for installing unfinished hardwood flooring.

Precautions Regarding Use of this Tool to Install Prefinished Flooring

It may also be used to install prefinished wood flooring materials, however precautions must be taken to assure that the finish will not be damaged by the tool. Before using the tool on prefinished material, test a sample section to assure that the tool and installation technique does not leave marks on the finish. This procedure must be followed for every installation due to variations in flooring materials and condition of the tool.

Do not discharge fasteners into open air, concrete, stone, or any other material too hard for the fastener to penetrate. Use of this tool by inexperienced operators must be supervised.

WARNING: Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to the State of California to cause cancer, birth defects and 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 exposure 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."

SAFETY INSTRUCTIONS

WARNING: EYE PROTECTION which conforms to ANSI specifications and provides protection against flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and others in the work area when connecting to air supply, loading, operating or servicing this tool. Eye protection is required to guard against flying fasteners and debris, which could cause severe eye injury.

The employer and/or user must ensure that proper eye protection is worn. Eye protection equipment must conform to the requirements of the American National Standards Institute, ANSI CAN/CSA Z94.3 and provide both frontal and side protection. NOTE: Non-side shielded spectacles and face shields alone do not provide adequate protection.

CAUTION: Additional Safety Protection will be required in some environments. For example, the working area may include exposure to noise level which can lead to hearing damage. The employer and user must ensure that any necessary hearing protection is provided and used by the operator and others in the work area. Some environments will require the use of head protection equipment. When required, the employer and user must ensure that head protection conforming to ANSI CAN/CSA Z89.1 is used.

Tool Air Fitting

This tool uses a 3/8" N.P.T. male plug. The inside diameter should be .275" (7 mm) or larger. The fitting must be capable of discharging tool air pressure when disconnected from the air supply.

Operating Pressure

70 to 90 p.s.i.g. (4.9 to 6.3kg / cm^2 ). Select the operating pressure within this range for best fastener performance. DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.

Air Consumption

The DWMIIIFS requires 4.2 cubic feet per minute (221 liters per minute) of free air to operate at the rate of 60 fasteners per minute, at 80 p.s.i. (5.6kg / cm^2) . 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.

OPERATION

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. (10.6kg / cm^2) 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. Too much oil will only collect inside the tool and will be noticeable in the exhaust cycle.

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.

NOTICE: 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.

NOTICE: Some commercial air line drying liquids are harmful to "O"-rings and seals - do not use these low temperature air dryers without checking compatibility.

Loading The DWMIIIFS

WARNING: EYE PROTECTION which conforms to ANSI specifications and provides protection against flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and others in the work area when connecting to air supply, loading, operating or servicing this tool. Eye protection is required to guard against flying fasteners and debris, which could cause severe eye injury.

The employer and/or user must ensure that proper eye protection is worn. Eye protection equipment must conform to the requirements of the American National Standards Institute, ANSI CAN/CSA Z89.1 and provide both frontal and side protection. Non-side shielded spectacles and face shields alone do not provide adequate protection.

WARNING: TO PREVENT ACCIDENTAL INJURIES:

• Never place a hand or any other part of the body in nail discharge area of tool while the air supply is connected.
• Never point the tool at anyone else.
• Never engage in horseplay.
• Never actuate the tool unless nose is directed at the work.
  Always handle the tool with care.
• Do not actuate the tool while loading.

STAPLE LOADING

NOTE: Use only staples recommended for use in the DWMIIIFS stapler or staples which meet the DEWALT specifications.

BEFORE HANDLING OR OPERATING THIS TOOL

WARNING:

I. READ AND UNDERSTAND THE WARNINGS CONTAINED IN THIS MANUAL.
II. REFER TO "TOOL SPECIFICATIONS" IN THIS MANUAL TO IDENTIFY THE OPERATING SYSTEM ON YOUR TOOL.

IN ADDITION TO THE OTHER WARNINGS CONTAINED IN THIS MANUAL OBSERVE THE FOLLOWING FOR SAFE OPERATION

WARNING:

• Use the DEWALT pneumatic tool only for the purpose for which it was designed.
• Never use this tool in a manner that could cause a fastener to be directed toward the user or others in the work area.
• Do not use the tool as a hammer.
• Always carry the tool by the handle. Never carry the tool by the air hose.
• Do not alter or modify this tool from the original design or function without approval from DEWALT.
• Always be aware that misuse and improper handling of this tool can cause injury to yourself and others.
• Before using the tool, verify that the actuator is in the non-actuated position. With the tool disconnected from the air supply, depress the actuator and confirm it returns to the non-actuated position.
• Never leave a tool unattended with the air hose attached.
• Do not operate this tool if it does not contain a legible WARNING LABEL.
• Do not continue to use a tool that leaks air or does not function properly. Notify your nearest DEWALT representative if your tool continues to experience functional problems.

Using the Tool

1. Position the tool on the tongued edge of the flooring strip aligning the driver guide against the front of the flooring strip.
2. Hold the handle firmly and strike the rubber cap sharply with the rubber end of the mallet. The tool will then drive the staple. DO NOT USE THE METAL END OF THE Mallet TO STRIKE THE RUBBER CAP, use the rubber end only.

MAINTENANCE

MAINTAINING THE PNEUMATIC TOOL

WARNING: Disconnect air line from tool and remove fasteners from magazine before making adjustments or repairs.

WARNING: When working on air tools, note the warnings in this manual and use extra care evaluating problem tools.

CAUTION: Pusher spring (constant force spring). Caution must be used when working with the spring assembly. The spring is wrapped around, but not attached to, a roller. If the spring is extended beyond its length, the end will come off the roller and the spring will roll up with a snap, with a chance of pinching your hand. Also the edges of the spring are very thin and could cut. Care must also be taken to insure no permanent kinks are put in the spring as this will reduce the springs force.

REplacement PARTS

Use only DEWALT replacement parts.

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.

Maintaining The DWMIII Series Tools

TO REPLACE PISTON

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

A. It is not necessary to disassemble the piston-poppet-driver assembly to replace the driver. Pull the poppet up on the driver piston stem as far as it will go.
B. 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.
C. To remove the driver blade from the piston stem, push the driver blade pin out of the stem. This will release the blade.
D. 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.

E. Assemble plunger flush with end of piston stem.
