1. Power Source
V Use only clean, dry, regulated compressed air as a power source
for this Tool
V Air compressors used to supply compressed air to this Tool
must comply with the requirements of the latest version of ANSI
Standard B 19.3 “Safety Standard For Compressors For Process
Industries.”
V Moisture or oil in the air compressor may accelerate wear and
corrosion in the Tool.
Drain daily.
V Air volume is as important as air pressure. The air volume
supplied to the tool may be inadequate because of undersized
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, jamming, miss‑feeds
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 con‑
taining water and anything else that would prevent full volume
flow of air to the tool.

safe operation of the Tool. Inspect the regulator
before operation to be sure it operates properly.
Inspect the lubricator before operation to be sure
the supply of lubricant is adequate. Use Hitachi
pneumatic tool lubricant.
3. Air Hose
Air hoses should have a minimum of 150 psi (10.4 bar 10.6 kgf/
2
cm
) 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 disconnect‑
ing” from the male plug on the Tool.
4. Hose Coupling
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. This Tool uses a 3/8” NPT. male plug. The in‑
side diameter should be .275” (7mm) or larger. The fitting must
be capable of discharging Tool air pressure when disconnected
from the air supply.
5. Air Consumption
The Tool requires 4.2 cfm 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 in‑
stance, if your fastener usage averages 30 fasteners per minute,
you need 50% of the Tools cfm.
6. Operating Pressure
70 to 90 psi. Select the operating pressure within this range
for best fastener performance. DO NOT EXCEED THIS RECOM‑
MENDED OPERATING PRESSURE.
— 17 —
English
LUBRICATION
Frequent, but not excessive, lubrication is required for best perfor‑
mance. Oil added through the air line connection will lubricate the
internal parts. Use Pneumatic 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 Piston Cushion in the
Tool, resulting in poor tool performance and frequent Tool mainte‑
nance.
If no airline lubricator is used, add oil during use into the air fitting
on the Tool once or twice a day. Only a few drops of oil at a time
are necessary. Too much oil will only collect inside the Tool and will
be noticeable in the exhaust cycle.
COLD WEATHER CARE
For cold weather operation, near and below freezing, the moisture
in the air line may freeze and prevent Tool operation. We recom‑
mend the use of WINTER FORMULA air tool lubricant (NEW‑MATIC
Winter Formula or equivalent) or permanent anti freeze (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.
CAUTION
Do not operate the Tool at high pressure without fasteners

metal portion of the mallet. Use the rubber capped end only to
prevent possible injury and/or damage to the Tool.
Do not drive fasteners into thin boards or near corners and
•
edges of work piece. Fasteners can be driven through or away
from work piece and hit someone.
Do not overdrive fasteners. NOFMA states that one reason for
•
split tongues is overdriving.
Never use Tool which is defective or operating abnormally.
•
Do not use Tool as a hammer.
•
Disconnect air hose from Tool when:
•
1) It is not in use;
2) Leaving work area;
3) Moving it to another location; and
4) Handing it to another person.
Wear safety glasses and safety shoes for protection against
•
foreign objects.
Never use a Hammer with a loose head or splintered handle.
•
Use only fasteners from Hitachi.
•
Air supply hoses should have a minimum working pressure
•
rating of 150 psi or 150 percent of the maximum pressure produced in the power source, whichever is higher.
Check all hoses before connecting to ensure that they are free
•
from dirt, grit, or particles that could alter the performance of
the tool.
An airline Filter and In-Line Air Regulator adjustable to 125 psi
•
max are required.
NEVER use a defective tool. Replace worn or damaged parts
•
immediately. Be sure that the Safety Trigger and operating
mechanisms operate correctly and that all screws and seals are
securely tightened at all times.
English
METHODS OF OPERATION
After connection with power source is made, check to be sure that
the airline Regulator pressure is 70‑90 psi. Note: Some materials
may require a higher pressure in order to countersink the fastener.
Harder Material Flooring requires more pressure than typical Oak
or Maple. Face Nailing requires approximately 5 psi or more than
Angle Nailing.
Ensure that Tool is in proper working order and that there is no
leaking of air. If there is an air leak, Disconnect Immediately! Ar‑
range for repairs by a Hitachi authorized service center.
After being sure Tool is operable, place Tool in position to be used.
Always place the Tool in proper position against the flooring to be
fastened before depressing the trigger and striking the ram.

The NT50AF Pneumatic Flooring Nailer and N5009AF Pneumatic
Flooring Stapler have a safety trigger that prevents accidental op‑
eration if ram cap is hit while connected to power source. Squeeze
safety lever to enable the Tool. Releasing the safety lever re‑engag‑
es the safety and renders the Tool inoperable.
To operate Tool, depress safety trigger while Tool is in position of
use, and tap the ram cap with a minimal stroke from the hammer.
If on the first initial operation a fastener does not eject into the
flooring, repeat hammer blow. This will ensure that the driver
blade/Piston is properly reset to allow the driver blade/piston to be
in the correct position to drive the fastener.
DO NOT OVERPOWER THE TOOL– A 90lb static force will oper‑
ate the Tool. This is easily achieved by a tap of the Hammer. If the
Flooring is warped or bowed, the ram can be hit firmly to tighten
the flooring. Try to avoid this constant wear, as abusive blows by
the hammer could damage tool and / or internal parts.
DO NOT HIT THE TOOL HARD
This Tool is pneumatically powered and requires only actuation by
depressing the safety trigger and tapping the ram head.
Note: The NT50AF Pneumatic Flooring Nailer and N5009AF Pneu‑
matic Flooring Stapler will not drive a fastener if the ram cap is
struck by hammer and the safety trigger is not depressed.
The NT50AF Pneumatic Flooring Nailer and N5009AF Pneumatic
Flooring Stapler are user‑friendly and following these simple
instructions, will insure a very high quality hardwood flooring
installation.
If the fastener is not properly seated, increase pressure incremen‑
tally until fastener is seated. DO NOT EXCEED 90 PSI!
WARNING
Keep your finger off the trigger except during fastening opera-
•
tion, because serious injury could result if the contact ram
accidentally contacts you or others in the work area.
Keep hands and body away from the discharge area. The Tool
•
may bounce from recoil of driving a fastener and unwanted
subsequent fastener may be driven, possibly causing injury.
Some types of loaded fasteners can spark out of the muzzle
•
during a driving operation. Exercise caution!

INSTALLING TONGUE AND GROOVE FLOORING
Caution regarding use of this Tool to install pre-finished flooring
This 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; however, caution must
be used to ensure that the finish is not damaged by the Tool. In all
flooring applications, 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.
After squaring the floor and allowing for expansion as recommend‑
ed by the Wood Flooring Industry (NWFA, NOFMA and MFMA),
install felt vapor barrier and use chalk line to identify location of
subfloor nails prior to racking wood to be installed. This will help
prevent hitting subfloor nails which can cause damage to the driver
blade and jamming. Place the grooved edge of the first row of
flooring towards the wall on the side of the room from which you
are starting.
Face nail first four (4) rows of flooring.
Install the tongue and groove shoe.
Place the groove of the fifth row of flooring over the tongue of the
fourth row of flooring and tighten using the hammer. Depress the
safety trigger, and tap ram head of the Tool with the tongue and
groove shoe installed.
Slide the Tool along the tongue of the flooring to the location at
which you desire to place the next fastener.
Continue until you have completely fastened all but the last five (5)
rows of flooring.
Install and face nail in place the remaining five (5) rows of flooring.
