Make sure of the following before operation.
WORKING ENVIRONMENT
WARNING
No flammable gas, liquid or other flammable objects at work-
•
site.
Clear the area of children or unauthorized personnel.
•

English
AIR SUPPLY
DANGER
NEVER use oxygen or other bottled
•
gases. Explosion may occur.
WARNING
Never connect Nailer to pressure which potentially exceeds
•
200 psi (13.7 bar 14 kgf/cm2).
Never use non relieving coupler on Nailer.
•
1. Power Source
V Use only clean, dry, regulated compressed air as a power source
for this Nailer
V Air compressors used to supply compressed air to this Nailer
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 Nailer.
V Drain daily.
V Air volume is as important as air pressure. Both should be con-
sidered when choosing a compressor to use with this tool. 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. Inadequate or restricted air flow will prevent
the tool from receiving an adequate volume of air, even though
the pressure reading is high. Compressors with lower CFM ratings may experience inadequate air flow while the compressor
is running. Low volume or pressure may result in slow opera-
tion, jamming, miss-feeds or reduced driving power.
V Air Compressor:

•PressureSwitchTripOn:110PSI(±5)
•PressureSwitchTripOff:135PSI(±5)
ALWAYS follow the Air Compressor Manufacturers’ recommen-
dations for adjustments.
2. Filter-Regulator-Lubricator
There should be an Air-Line Filter between the Pressure Regu-
lator and the Air Compressor to insure clean, dry air. Filter on
Air-Line must be drained after use every day. The Air Compres-
sor should have an air inlet filter. The filter medium should
be cleaned or replaced as needed or as recommended by the
manufacturer of the filtration unit. The air compressor must be
equipped with a condensate drain at bottom of the accumulator
tank. The accumulator tank should be drained after each day’s
use.
3. Air Hose
3/8” ID is recommended. Air supply hoses should have a mini-
mum working pressure rating of 150 PSI (10.4 bar 10.6 kgf/cm2)
or 150 percent of the maximum pressure produced in the power
source, whichever is higher.
4. Hose Coupling
Any configuration of quick connect fittings with either a 3/8”
NPT thread or a combination of a 1/4 NPT thread fitting and 3/8 –
1/4 NPT reducer. The fitting must be capable of discharging tool
air pressure when disconnected from the air supply.
5. Air Consumption
The Tool requires 4.6 cubic feet per minute of free air to operate
at the rate of 60 fasteners per minute @ 90 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 CFM of free air
which is required to operate the tool at 60 fasteners per minute.
6. Operating Pressure
90 to 110 PSI Select the operating pressure within this range for
best fastener performance. DO NOT EXCEED 120 PSI.
— 15 —
English
LUBRICATION
The model NT50AGF Pneumatic Flooring Nailer is lubricated at the
factory using Mobilith SHC 460 synthetic grease or equivalent. It is
not necessary to lubricate the tool during normal day-to-day use.
The tool should be lubricated using the factory recommended lubricant at normal servicing intervals. (See SERVICE AND REPAIRS in
this manual.)
DO NOT USE AN IN-LINE OILER WITH THE NT50AGF Pneumatic
Flooring Nailer.
DO NOT INTRODUCE OIL, SOLVENTS, LUBRICANTS, OR WATER
INTO THE TOOL AS THIS WILL REDUCE THE EFFECTIVENESS AND
THE USEFUL LIFE OF THE TOOL.
COLD WEATHER CARE
Do not store the Nailer in a cold weather environment.
Keep the Nailer in a warm area until beginning the work.
If the Nailer is already cold, bring it in a warm area and allow the
Nailer to warm up before use.
(1) Reduce the air pressure to 64 psi (4.4 bar 4.5 kgf/cm2)
(2) Remove all nails from the Nailer.
(3) Connect the air hose and operate the Nailer without nails.
The lowered air pressure will be enough to operate the Nailer without nails.
Slow speed operation tends to warm up the moving part.
CAUTION
Do not operate the Nailer at high pressure without fasteners.

English
INSTALLING A FITTING
Before using the model NT50AGF Pneumatic Flooring Nailer, a 3/8”
Thread Fitting must be installed. The NT50AGF Pneumatic Flooring
Nailer has an adapter installed to accept a 3/8” Thread fitting. This
provides the owner the advantage of installing the preferred Fitting
of choice. (ie: Hitachi Fittings; Industrial (P/N 190051), Automotive
(P/N 190071)). This allows the freedom to use any configuration of
quick connect fitting with either a 3/8 NPT thread or a combination
of a 1/4 NPT thread fitting and 3/8 – 1/4 NPT reducer. Install the Fitting into the supplied adapter and gently tighten.
CAUTION: Do not remove the installed adapter. This adaptor provides connection of the Fitting of choice as well as protecting the
integrity of the NT50AGF Pneumatic Flooring Nailer Body from inlet
port damage.
IMPORTANT: The
bottom hole of the
NT50AGF that is
plugged should
NEVER be removed.
If plug is removed,
the NT50AGF Pneumatic Flooring Nailer
will not perform correctly and serious
damage may occur.
CHANGING FLOORING SHOES
Loosen or remove Flange Nuts (Ref. No. 33) with Wrench and
unscrew the Shoe Screw (Ref. No. 50) to remove and change over
from Tongue Nailing to Face Nailing Applications. Change from
Face Nailing to Tongue Nailing by loosening or removing Flange

METHODS OF OPERATION
After connection with power source is made, check to be sure that
the airline Regulator pressure is 90-115 PSI. Note: Some materials may require a higher pressure in order to countersink the nail.
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! Arrange 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
nailed before depressing the Trigger and striking the Ram.

English
The NT50AGF Pneumatic Flooring Nailer has a Safety trigger that
prevents accidental operation if Ram Cap is hit while connected to
power source. Squeeze Safety Lever to enable the Nailer. Releasing the Safety Lever re-engages the Safety and renders the Nailer
inoperable.
To operate tool, depress Safety Trigger while tool is in position of
use, and tap the Ram Cap (Ref. No. 47) with a minimal stroke from
the Hammer.
If on the first initial operation a nail 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 (Ref. No. 36) to be
in the correct position to drive the nail.
DO NOT OVERPOWER THE NAILER – A 90lb static force will operate the Nailer. 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.
— 22 —
English
DO NOT HIT THE TOOL HARD
Do not hit the tool hard. A tap is all that is required to operate the
tool. Not more than a 12” stroke is required.
This Nailer is pneumatically powered and requires only actuation
by depressing the Safety Trigger and Tapping the Ram Head.
NOTE: The NT50AGF Pneumatic Flooring Nailer will not drive a nail
if the Ram Cap is struck by Hammer and the Safety Trigger is not
depressed.
The NT50AGF Pneumatic Flooring Nailer is user-friendly and following these simple instructions, will insure a very high quality
Hardwood Flooring installation.
If the nail is not properly seated, increase pressure incrementally
until nail is seated. DO NOT EXCEED 120 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 nailer
•
may bounce from recoil of driving a fastener and unwanted
subsequent fastener may be driven, possibly causing injury.
Some types of loaded nails can spark out of the muzzle during
•
a driving operation. Exercise caution!
INSTALLING TONGUE AND GROOVE FLOORING
Install the Face Nailing Shoe on the NT50AGF Pneumatic Flooring
Nailer (See Shoe Changing Section Page 17).
After squaring the Floor and allowing for expansion as recommended by the Wood Flooring Industry (NWFA, NOFMA and
MFMA), install Felt Vapor Barrier and use chalk line to identify
location of Sub-Floor Nails prior to racking wood to be nailed. This
will help prevent hitting Sub-Floor 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.
Be careful to tap both the Ram Head of the NT50AGF Pneumatic
Flooring Nailer and the Flooring with the Gray Cap on the Hammer.
Tapping the Ram Head or tapping the Flooring with the metal end
of the Hammer will cause damage to the Nailer or the Flooring.

SERVICE AND REPAIRS
WARNING
Only service personnel trained by Hitachi, distributor or em-
•
ployer shall repair the Nailer.
Use only Hitachi parts supplied or recommended by Hitachi for
•
repair.
All quality Nailers will eventually require servicing or replacement
of parts because of wear from normal use.
In order to achieve the optimal performance of the NT50AGF Pneumatic Flooring Nailer, preventative Maintenance is recommended.
Manufacturer recommends replacement & re-greasing the Piston
O-Ring every 25,000 strokes (25,000 Nails). This will help prevent
premature wear and/or damage to the Piston & Cylinder and allow
the Nailer to be operated at the lower air pressure range.
Manufacturer recommends replacement & Lubrication of the ORings in the Valve Body Assembly every 100,000 strokes (100,000
Nails). Again, this recommendation will help achieve longevity and
optimal performance of the NT50AGF Pneumatic Flooring Nailer.
NOTE:
Specifications are subject to change without any obligation
on the part of HITACHI.

compressor is running you may
need to wait until it cuts off to
continue nailing.
Only Tap the Ram to operate
the Nailer. If you are raising the
hammer more than 12” above
the ram head you are more
likely to hit the ram too hard.
Contact Hitachi for replacement.
Check Access Gate (Ref. #22) to
ensure it’s properly closed.
Check Rail (Ref. #26) for wear
on the end. If worn, turn rail
around to use other end in
Guide or replace the rail. Make
sure pusher provides positive
pushing force on the nail clip to
prevent nails from turning.
Set air pressure to 100-115 PSI.
Smaller air compressors supplying a lower than recommended volume of air, may
require you to wait for the
compressor to ‘catch up’. If air
compressor is running you may
need to wait until it cuts off to
