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 springs force.
REPLACEMENT PARTS:
Genuine Hitachi replacement parts are recommended. Do not use modified parts or
parts which will not give equivalent performance to the original equipment.
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. Apply two drops of air tool lubricant prior to subsequent use.
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 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, 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.
• Air pressure too low.
• Staple crown above tongue.
• Increase air pressure.
• Air pressure too high.
• Staple buried.
• Lower air pressure.
• Correct air pressure.
• Staple just below surface.

prior to making any modificaons to the tool.
Other Detailed Informaon
Refer to the tool maintenance instrucons for detailed informaon
on the proper maintenance of the tool.
Actuaon System
This tool ulizes a dual trigger single sequenal actuaon system.
The contact safety located in the nose of the tool must be held
depressed and either of the two triggers pulled to actuate the tool.
The trigger must be pulled for each subsequent actuaon provided
that the contact safety remains depressed against the work piece
for subsequent actuaons. The contact safety is included to prevent
accidental actuaon of the tool. Do not defeat or disable the contact
safety.
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

8
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
in such a manner that all compressed air in the tool is discharged at
the me the fing or hose coupling is disconnected.

2. PULL BACK MAGAZINE.
3. OPEN MAGAZINE FULLY.
4. INSERT FASTENERS, POINTS MUST BE AGAINST BOTTOM OF MAGAZINE.
5. PUSH MAGAZINE FORWARD. CONTINUE PUSHINGUNTIL LATCH IS
ENGAGED.
FASTENER POSITIONING ADJUSTMENT
The fastener posion can be adjusted to accommodate 1/4” - 7/16” thicknesses
of flooring by way of the adjustment knobs located on the posioning shoe. The
shoe adjustment feature provides close control of the fastener posioning to reduce
occurrence of split tongues or dimples in the flooring surface.
First set the air pressure for consistent drive in the specific work as described on
page 4, then use the shoe adjustment knobs to set the desired posion of drive. The
fastener should be posioned so that it enters the vercal face of the flooring at the
point where the tongue meets the vercal face.
TO ADJUST THE TOOL TO THE FLOORING:
1. Loosen both Knobs unl the Foot and Front Guide move freely.
2. Engage the Nose with the Tongue of Flooring.
3. Push the Front Guide to the subfloor and the Foot to the flooring.
4. Tighten both Knobs.
Note: periodically check the Knobs to ensure that they are ght during use.
**Important: Test the tool on a scrap piece of flooring to ensure proper staple placement and compability.

SEQUENTIAL TRIP SAFETY OPERATION
The model 475 flooring stapler operates on a sequenal trip system. The sequenal
trip system requires the operator to hold the tool against the work before pulling
the trigger. This makes accurate fastener placement easier. The sequenal trip
allows exact fastener locaon without the possibility of driving a second fastener on
recoil. The sequenal trip system has a posive safety advantage because it will not
accidentally drive a fastener if the tool is contacted against the work – or anything
else – while the operator is holding the trigger pulled.
TOOL OPERATION CHECK:
CAUTION: Remove all fasteners from tool before performing tool operaon check.
SEQUENTIAL TRIP OPERATION:
A. Press the contact trip against the work surface, without touching the trigger.
THE TOOL MUST NOT CYCLE.
B. Hold the tool offthe work surface and pull the trigger.
THE TOOL MUST NOT CYCLE.
Release the trigger. The trigger must return to the trigger stop on the frame.
C. Pull the trigger and press the contact trip against the work surface.
THE TOOL MUST NOT CYCLE.
D. With finger offthe trigger, press the contact trip against the work surface. Pull
the trigger.
THE TOOL MUST CYCLE.
DUAL TRIGGER OPERATION (PATENT PENDING)
The dual trigger feature gives you mulple opons for hand orientaon and trigger
actuaon to allow you to choose the actuaon method that works best for you for a
given applicaon. The following illustraons are two examples.

TOOL AIR FITTING:
This tool uses a free-flow connector plug, 1/4 NPT. The inside diameter should be
.200” (5mm) or larger. The fing must be capable of discharging tool air pressure
when disconnected from the air supply.
OPERATING PRESSURE:
70 to 100 PSIG. (4.8 to 7.0 kg/cm2). Select the operang pressure within this range
for best fastener performance. DO NOT EXCEED THE RECOMMENDED OPERATING
PRESSURE.
AIR CONSUMPTION:
The model 475 requires 3.1 cubic feet per minute (.09 cubic meters) of free air to
operate at the rate of 100 fasteners per minute, at 80 PSI (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 50 fasteners per minute, you need 50% of
the tool’s C.F.M. which is required to operate the tool at 100 fasteners per minute.
SEQUENTIAL TRIP OPERATION:
The model 475 flooring stapler operates on a sequenal trip system. The sequenal
trip system requires the operator to hold the tool against the work before pulling
the trigger. This makes accurate fastener placement easier. The Sequenal Trip
allows exact fastener locaon without the possibility of driving a second fastener on

AIR SUPPLY AND CONNECTIONS
WARNING:
!
Do not use oxygen, combusble gases, or boled 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 PSI (10.6 kg/cm2) 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 BOTTLEDGASES, AS A POWER SOURCE FOR THIS
TOOL AS TOOL MAY EXPLODE.
REGULATOR:
A pressure regulator with an operang pressure of 0 - 125 PSI (0 - 8.79 KG/CM2) 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 (14 KG/CM2)
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
for the 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:
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
11
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.
COLDWEATHER 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.
