SAFETY — Continued
WARNING
When using tools, basic precautions should always be followed, Including the following:
1. Work area
(1) Keep the work area clean and well lighted.
Cluttered benches and dark areas increase the risks
of electric shock, fire, and injury to persons.
(2) Do not operate the Nailer in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or combustible dust.
The Nailer is able to create sparks resulting in the
ignition of the dust or fumes.
(3) Keep bystanders, children, and visitors away
while operating the Nailer. Distractions are able to
result in the loss of control of the Nailer.
2. Personal safety
(1) Stay alert. Focus on your work and use common
sense when working with the Nailer. Do not use
the Nailer while tired, after having consumed
drugs or alcohol, or while under the influence of
medication.
A moment of inattention while operating the Nailer
increases the risk of injury to persons.
(2) Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep hair, clothing,
and gloves away from moving parts.
Loose clothes, jewelry, or long hair increases the
risk of injury to persons as a result of being caught in
moving parts.
(3) Avoid unintentional starting. Be sure the switch
is offbefore connecting to the air supply. Do
not carry the Nailer with your finger on the switch or
connect the Nailer to the air supply with the switch on.
(4) – Disconnect the Nailer from
the air source before making adjustments, doing
Nailer maintenance, clearing jams, attaching
or removing the nose cap, when not in use,
leaving work area, leaving the Nailer outside of
the operator’s supervision or control, loading,
or unloading the Nailer, handing it to another
person, elevating, lowering or otherwise moving
the Nailer to a new location. Never attempt to
clear a jam or repair the Nailer unless you have
disconnected air hose from the Nailer and removed
all remaining fasteners from the Nailer. The Nailer
should never be left unattended since people who are
not familiar with the Nailer might handle it and injure
the themselves.
Such precautionary measures reduce the risk of
injury to persons.
(5) Do not overreach. Keep proper footing and
balance at all times. Proper footing and balance
enables better control of the Nailer in unexpected
situations.
(6) Use safety equipment. A dust mask, non-skid
safety shoes and a hard hat must be used for the
applicable conditions.
(7) – Risk of hearing loss. Wear
hearing protection.
Hearing protection shall have a Noise Reduction
Rating (NRR) determined in accordance with US
Environmental Protection Agency rules that is
appropriate for noise exposure.
(8) Always wear head protection.
Always wear head protection to protect your
head from flying objects.
(9) Do not attach the hose or Nailer to your body.
Attach the hose to the structure to reduce the risk of
loss of balance if the hose shifts.
(
10 ) – Drive Nails into proper work
surface only. Do not drive nail into other nails. This
is able to cause the fastener to be deflected and hit
someone, or cause the Nailer to react and result in a
risk of injury to persons.
3. Nailer use and care
(1) Use clamps or another practical way to secure
and support the workpiece to a stable platform.
Holding the work by hand or against the body is
unstable and is able to lead to loss of control.
(2) Do not force the Nailer. Use the correct Nailer for
the application. The correct Nailer will do the job
better and safer at the rate for which the Nailer is
designed.
(3) Do not use the Nailer if the switch does not
turn the Nailer on or off. Any Nailer that cannot be
controlled with the switch is dangerous and must be
repaired.
Never use Nailer which is defective or operating
abnormally. If the Nailer appears to be operating
unusually, making strange noises, or otherwise
appears defective, stop using it immediately and
arrange for repairs by a Hitachi authorized service
center.

(4) Disconnect the Nailer from the air source before
making any adjustments, changing accessories,
or storing the Nailer. Such preventive safety
measures reduce the risk of starting the Nailer
unintentionally.
(5) Store the Nailer when it is idle out of reach of
children and other untrained persons. A Nailer is
dangerous in the hands of untrained users.
(6) Maintain the Nailer with care. Keep the
Nailer Clean and lubricated for better and safer
performance.
(7) Check for misalignment or binding of moving
parts, breakage of parts, and any other condition
that may affect the Nailer’s operation.
If damaged, have the Nailer serviced before using.
Because of high air pressure in the Nailer, cracks in
the surface are dangerous. To avoid this, do not drop
the Nailer or strike the Nailer against hard surfaces;
and do not scratch or engrave signs on the Nailer.
Many accidents are caused by poorly maintained
Nailers. There is a risk of bursting if the Nailer is
damaged.
(8) Do not use the Nailer that is not in proper
working order. Tags and physical segregation
shall be used for control.
(9) Use only accessories that are identified by
Hitachi for the specific Nailer. Use of an accessory
not intended for use with the specific Nailer ,
increases the risk of injury to persons.
(
10 ) Use only those fasteners listed in the
Accessories section of this manual. Fasteners not
identified for use with this Nailer by Hitachi are able to
result in a risk of injury to persons or Nailer damage
when used in this Nailer.
4. Service
(1) Tool service must be performed only by qualified
repair personnel.
(2) When servicing a Nailer, use only identical
replacement parts. Use only authorized parts.
(3) Use only the lubricants supplied with the Nailer
or specified by Hitachi.
5. Air source
(1) Never connect to an air source that is capable
of exceeding 200 psi (13.7 bar 14 kgf/cm2) if a
regulator fails.
Over pressurizing the Nailer is able to result in
bursting, abnormal operation, breakage of the Nailer
or serious injury to persons.
DO NOT EXCEED 100 psi (6.9 bar 7 kgf/cm2).
Use only clean, dry, regulated compressed air at the
rated pressure or within the rated pressure range as
marked on the Nailer.
Always verify prior to using the Nailer that the air
source has been adjusted to the rated air pressure or
within the rated air-pressure range.
(2) Never use reactive gases such as oxygen,
carbon dioxide, combustible gases or any
bottled gas as an air source for the Nailer. Such
gases are capable of explosion and serious injury to
persons.
6. Others
(1) Be careful of unwanted ejection or being hit by
the Nailer due to spring back (“recoil”).
After driving a nail, the Nailer may recoil causing it to
move away from the work surface.
To reduce risk of injury always manage recoil by:
1) always maintaining control of the Nailer.
2) allowing recoil to move the Nailer away from work
surface.
3) not resisting recoil such that the Nailer will be
forced back into the work surface.
4) pulling the trigger rapidly and firmly, and releasing
it QUICKLY.
5) keeping face and body parts away from the Nailer.
(2) Never Use NON relieving coupler on Nailer. If a
non relieving coupler is used on the Nailer, the Nailer
can remain charged with air after disconnecting
and thus will be able to drive a fastener even after
disconnecting. The Nailer and air hose must have a
hose coupling such that all pressure is removed from
the Nailer when the coupling joint is disconnected.
(3) Check double trigger before use.
The Nailer will not operate unless you pull the lock
lever before you pull the trigger.

1. Power source
○ Use only clean, dry, regulated compressed air as a
power source for this Nailer.
○ 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”.
○ Moisture or oil in the air compressor may accelerate
wear and corrosion in the Nailer.
Drain daily.
2. Filter-Regulator-Lubricator
○ Use a regulator with a pressure range of 0 – 100 psi
(0 – 6.9 bar 0 – 7 kgf/cm2).
○ Filter-regulator-lubricator units supply an optimum
condition for the Nailer and extend the Nailer life.
These units should always be used.
Filter ................ The filter removes moisture and dirt
mixed in compressed air.
Drain daily unless fitted with an
automatic drain.
Keep the filter clean by regular
maintenance.
Regulator......... The regulator controls the operating
pressure for safe operation of the
Nailer.
Inspect the regulator before operation
to be sure it operates properly.

3. Air hose
Compressed air supply hoses shall have a minimum
working pressure rating equal to or greater than the
pressure from the power source if a regulator fails, or
150 psi (10.4 bar 10.6 kgf/cm2), whichever is greater.
4. Air consumption
Using the Air consumption table and the Air
compressor size formula, find a correct compressor
size.

consumption
ft3/cycle .011 .015 .018
(ltr/cycle) (.3) (.4) (.5)
Air compressor size formula
Amount of air required
= number of Nailers
× average nails driven each minute per Nailer
× air consumption at given air pressure
× safety factor (always 1.2)
Example: 3 Nailers operating at 100 psi driving 30
nails per minute
Amount of air required
= 3 × 30 × .018 (.5) × 1.2
= 1.9 CFM (ft3/min) (94 ltr/min)
After making the calculations as shown above, you
should find a compressor providing 1.9 CFM of air
that is required.
LUBRICATION
It is important that the Nailer be properly lubricated.
Without proper lubrication, the Nailer will not work
properly and parts will wear prematurely.
○ Use Hitachi pneumatic tool lubricant.
Do not use detergent oil or additives. These lubricants
will harm the O-rings and other rubber parts. This will
cause the Nailer to malfunction.
○ Filter-regulator-lubricator units should always be used.
Keep the lubricator filled with Hitachi pneumatic tool
lubricant.
○ If a lubricator is not available, supply 5 – 10 drops of
Hitachi pneumatic tool lubricant into the air plug on the
Nailer twice a day.
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 free-fire (blank-fire) the
Nailer.
The lowered air pressure will be enough to free-
fire the Nailer.

ADJUSTING AIR PRESSURE
WARNING
● Do not exceed 100 psi (6.9 bars 7 kgf/cm2).
Adjust the air pressure at recommended operating
pressure 64 – 100 psi (4.4 – 6.9 bar 4.5 – 7 kgf/cm2)
according to the length of nails and the hardness of
workpiece.
The correct air pressure is the lowest pressure which will
do the job. Using the Nailer at a higher than required air
pressure unnecessarily over stresses the Nailer.
