TOOL AIR FITTING:
This tool uses a 3/8” NPT male plug. The inside diameter should be
.275” (7mm) or larger. The fing must be capable of discharging
tool air pressure when disconnected from the air supply.
OPERATING PRESSURE:
70 to 90 PSI Select the operang pressure within this range for
best fastener performance. DO NOT EXCEED THIS RECOMMENDED
OPERATING PRESSURE.
AIR CONSUMPTION:
The Tool requires 4.2 cubic feet per minute (221 liters per minute)
of free air to operate at the rate of 60 fasteners per minute @ 80 PSI
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.
Cauon regarding Use of this Tool to Install Pre-finished Flooring
This Flooring Tool was designed for use in installing unfinished
hardwood flooring. It can be used to install pre-finished flooring
when used with the Pre-Finish flooring accessory shoe (P/N 47090);
however, cauon must be used to ensure that the finish is not
damaged by the tool. In all flooring applicaons, it is recommended
that the tool be tested on a sample secon 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 variaons in
flooring and tool condion.

Actuaon System
This tool ulizes a dual trigger single sequenal actuaon system.
The safety trigger located within the handle must be held depressed
and the ram cap must be struck with the included mallet to
actuate the tool. The ram cap must be struck with the mallet for
each subsequent actuaon provided that the safety trigger is held
depressed for subsequent actuaons. The safety trigger is included
to prevent accidental actuaon of the tool. Repeated aempts to
actuate the tool while the safety trigger is released may damage the
safety mechanism and the tool.
Power Source
The compressed air power source shall be pressure-regulated. The
regulated pressure must not exceed the maximum air pressure
marked on the tool. If a regulator fails, the pressure delivered to the
tool must not exceed 1.5 mes the maximum air pressure, or 200
PSIG, whichever is greater. The tool normally is not operated at the
maximum air pressure but at a lower pressure determined by the
type of fastener used, the work piece, and other condions of use.
Hazardous Power Source
Hazardous power sources shall not be used. Hazardous power
sources include, but are not limited to the following:
Reacve gases including, but not limited to oxygen and•
combusble gases.
Pressure sources that can deliver in excess of 1.5 mes the•
maximum air pressure of the tool or 200 PSIG, whichever is
greater, if a regulator fails.
Regulator
Pressure regulators shall be used to limit the air pressure supplied
to the tool. Regulators shall be set at an operang pressure which is
lower than or equal to the tool manufacturer’s specified maximum
air pressure.
Hose
Air supply hoses shall have a minimum working pressure rang equal
to or greater than the pressure from the power source if a regulator
fails, or 150 PSIG, whichever is greater.
Disconnect
Tools shall be fied with a fing or hose coupling on or near the tool

TOOL OPERATION
BEFORE HANDLING OR OPERATING THIS TOOL READ AND
UNDERSTAND THE WARNINGS CONTAINED IN THIS MANUAL.
IN ADDITION TO THE OTHER WARNINGS CONTAINED IN THIS MANUAL
OBSERVE THE FOLLOWING FOR SAFE OPERATION.
Use the pneumac tool only for the purpose for which it was•
designed.
Do not e, tape, or otherwise disable the safety trigger as this•
could result in accidental discharge of the tool causing injury to
yourself and others.
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 strike the ram/actuator without pulling the safety•
trigger. Hing the tool repeatedly with the safety interlock
engaged will severely damage the safety mechanism and the
tool. This abuse and damage is not covered by the warranty.
Do not use the tool as a hammer.•
Always carry the tool by the handle. Never carry the tool by•
the air hose.
Always be aware that misuse and improper handling of this tool•
can cause injury to yourself and others.
Never leave a tool unaended with the air hose aached.•
Do not operate this tool if it does not contain a legible•
WARNINGLABEL.
Do not connue to use a tool that leaks air or does not funcon•
properly. Nofy your nearest store representave if your tool
connues to experience funconal problems.
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 form the tool while tool is in
operaon as accidental actuaon may occur, possibly causing
injury.
The operator must not hold the safety trigger pulled except•
during fastening operaon as serious injury could result if the
ram cap accidentally contacted someone or something with

10
enough force to cause the tool to cycle.
Keep hands and body away from the discharge area of the tool.•
The tool may bounce from the recoil of driving a fastener and
an unwanted second fastener may be driven possibly causing
injury.
When loading tool, never place a hand or any part of body in•
fastener discharge area of tool, never point tool at anyone,
do not pull the safety trigger or depress the ram/actuator as
accidental actuaon may occur, possibly causing injury.
Always disconnect the air supply before making adjustments,•
when servicing the tool, when clearing a jam, when tool is not
in use, or when moving to a different work area, as accidental
actuaon may occur, possibly causing injury.
Check operaon of the safety mechanism frequently. Do not•
use the tool if the safety is not working correctly as accidental
driving of a fastener may result. Do not interfere with the
proper operaon of the safety mechanism.
The safety trigger is a safety device and should only be pulled•
when the tool is in proper posion on the work surface and
before the ram/actuator is struck with the mallet. Do not e
or tape down the safety trigger as the tool could discharge if
dropped on the plunger. The tool will not fire unless the trigger
is pulled before striking the ram/actuator with the mallet.
Do not use the safety as a disabling mechanism for the ram/•
actuator in order to use the tool to rack the wood. This will
severely damage the mechanism and the tool. This abuse and
damage is not covered by the warranty. Use the mallet to rack
the flooring, not the tool.
Do not strike the ram/actuator without pulling the safety•
trigger! Hing the tool repeatedly with the safety engaged will
damage the safety mechanism and the tool.
Do not drive fasteners on top of other fasteners or with the•
tool at an overly steep angle as this may cause deflecon of
fasteners which could cause injury.
Do not strike the ram/actuator or any part of the tool with the•
metal poron of the mallet. Use the rubber capped end only to
prevent possible injury and/or damage to the tool.
Do not drive fasteners close to the end of the work piece as the•
wood may split, allowing the fastener to be deflected possibly

AIR SUPPLY AND CONNECTIONS
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 PSI working pressure rang
or 150 percent of the maximum pressure that could be produced
in the air system. The supply hose should contain a fing that will
provide “quick disconnecng” 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 operang pressure of 0-125 PSI is
required to control the operang pressure for safe operaon of this
tool. Do not connect this tool to air pressure which can potenally
exceed 200 PSI as tool may fracture or burst, possibly causing injury.
OPERATING PRESSURE:
Do not exceed recommended maximum operang pressure as tool
wear will be greatly increased. The air supply must be capable of
maintaining the operang pressure at the tool. Pressure drops in
the air supply can reduce the tool’s driving power. Refer to “TOOL
SPECIFICATIONS” for seng the correct operang pressure of tool.
FILTER:
Dirt and water in the air supply are major causes of wear in
pneumac 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 installaon. The filter has to be kept clean
to be effecve in providing clean compressed air to the tool. Consult
the manufacturer’s instrucons on proper maintenance of your filter.
A dirty and clogged filter will cause a pressure drop which will reduce
the tool’s performance.

LUBRICATION

14
Frequent, but not excessive, lubricaon is required for best
performance. Oil added through the air line connecon will lubricate
the internal parts. Use Air Tool Lubricant, Mobil Velocite #10, or
equivalent. Do not use detergent oil or addives as these lubricants
will cause accelerated wear to the seals and Piston Cushion in
the tool, resulng in poor tool performance and frequent tool
maintenance.
If no airline lubricator is used, add oil during use into the air fing
on the tool once or twice a day. Only a few drops of oil at a me are
necessary. Too much oil will only collect inside the tool and will be
noceable in the exhaust cycle.
COLD WEATHER OPERATION:
For cold weather operaon, near and below freezing, the moisture in
the air line may freeze and prevent tool operaon. We recommend
the use of WINTER FORMULA air tool lubricant (NEW-MATIC Winter
Formula or equivalent) or permanent anfreeze (ethylene glycol) as a
cold weather lubricant.
CAUTION: Do not store tools in a cold weather environment to
prevent frost or ice formaon on the tools operang 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 compability.

MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use
extra care evaluang problem tools.
CAUTION: Pusher Spring (constant force spring). Cauon must be
used when working with the spring assembly. The spring is wrapped
around, but not aached to a roller. If the spring is extended beyond
its length, the end will come offthe 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 spring’s force.
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and
lubricated. Use LITHIUM grease 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. Aer re-assembly, add a few
drops of Air Tool Lubricant through the air line fing before tesng.
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 undersized fings 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
operaon, jamming, miss-feeds or reduced driving power. Before
evaluang tool problems for these symptoms, trace the air supply
from the tool to the supply source for restricve connectors, swivel
fings, low points containing water and anything else that would
prevent full volume flow of air to the tool.
DRIVER BLADE ASSEMBLY / REMOVAL:
Disconnect the air supply.1.
Remove the Ram Cap with box wrench.2.
Unscrew & remove Body Cap.3.
Unscrew the four Cap Screws holding the Plunger to the Poppet.4.
Pull the Plunger up and out of the Body Cavity.5.
Turn the tool over and remove the four Cap Screws that fasten6.

be replaced.
Check the fit. There should be some sideways movement5.
between the Driver Blade and the Lock nut assembly. This is
desirable and helps the Driver Blade to align itself with mang
parts.
Reassemble the components and be sure to align the Driver6.
Blade with the slot in the Adapter Foot Assembly.
