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.

Safety Instructions - 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.

WARNING: Do not use supply sources which can potentially exceed 200 p.s.i.g.

(14kg/cm2 ) as tool may burst, possibly causing injury.

WARNING: 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.

3- ENG

WARNING: 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.

Safety Instructions - Loading Tool

WARNING: When loading tool: 1.) Never place a hand or any part of body in

fastener discharge area of tool; 2.) Never point tool at anyone; possibly causing injury.

Safety Instructions - Operation

WARNING: Always handle the tool with care: 1.) Never engage in horseplay; 2.)

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

WARNING: 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.

WARNING: 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.

WARNING: 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.

WARNING: 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.

WARNING: 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. Using the nailer
in any such environment could cause an EXPLOSION resulting in personal injury or
death to user and bystanders.

RANGE

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.

4- ENG

Operating Pressure

70 to 90 p.s.i.g. (4.9 to 6.3 kg/cm2). 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. (5.6 kg/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.

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. (10.6 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.

5- ENG

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.

MAINTENANCE
MAINTAINING THE PNEUMATIC TOOL

WARNING: Disconnect air line from tool and remove fasteners from magazine

before making adjustments or repairs.

7- ENG

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

8- ENG

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.
