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, re, and injury to persons.
(2) Do not operate the Nailer in explosive
atmospheres, such as in the presence of
ammable 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 in uence 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 o before connecting to the air supply. Do
not carry the Nailer with your nger 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, touching
the Push Lever, 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 ying 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 de ected 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 o . 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.
6
English
(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 a ect 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 identi ed by
Hitachi for the speci c Nailer. Use of an accessory
not intended for use with the speci c Nailer ,
increases the risk of injury to persons.
(10) Use only those fasteners listed in the
Accessories section of this manual. Fasteners not
identi ed 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 quali ed
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 speci ed by Hitachi.
5. Air source
(1) Never connect to an air source that is capable
of exceeding 200 psi (13.7 bar 14 kgf/cm
2
) 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 120 psi (8.3 bar 8.5 kgf/cm
2
).
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 double re and 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. InCONTACT
ACTUATION MECHANISM, if push lever is
allowed to re-contact work surface before the
trigger is released, an unintended discharge of a
nail will occur. In order to avoid this undesirable
double re,
Intermittent operation (Trigger re)
1
Pull the trigger rapidly and rmly.
2
Release the trigger QUICKLY.
SAFETY — Continued
WARNING

English
Continuous operation (Push lever re)
1
Do not press the Nailer against the wood with
excessive force.
2
Separate the Nailer from the wood as it recoils
after nailing.
4) 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 Push Lever before use. Make sure the
Push Lever operates properly, and is not inoperable,
disconnected, or altered. (The Push Lever may be
called “Safety.) Never use the Nailer unless the Push
Lever is operating properly, otherwise the Nailer
could drive a fastener unexpectedly. Do not tamper
with or remove the Push Lever, or otherwise cause
the Push Lever to become inoperable.
(4) Keep all screws and covers tightly in place. Keep
all screws and covers tightly mounted.
Check their condition periodically. Never use the
Nailer if parts are missing or damaged.
(5) Do not load fasteners with Trigger or Push Lever
depressed. When loading fasteners into the Nailer
or when connecting the air hose,
1) do not depress the Trigger;
2) do not depress the Push Lever; and
3) keep the Nailer pointed downward.
(6) Keep hands and body away from ring head
during use. Never place your hands or feet closer
than 8 inches (200 mm) from the ring head. A
serious injury can result if the fasteners are de ected
by the workpiece, or are driven away from the point of
entry.
(7) When working close to an edge of a workpiece
or at steep angles, or driving fasteners into
thin workpiece use care to minimize chipping,
splitting or splintering, or free ight, ricochet or
piercing of fasteners, which may cause injury.
(8) Never drive fasteners from both sides of a wall
at the same time. The fasteners can be driven into
and through the wall and hit a person on the opposite
side.
(9) Use extra caution when driving the Nailer into
existing walls or other blind areas to prevent
contact with hidden objects or persons on other
side (eg., wires, pipes).
(10) Check for live wires. Avoid the risk of severe
electrical shock by checking for live electrical wires
that may be hidden by walls, oors or ceilings. Turn
o the breaker switch to ensure there are no live
wires.
(11) Do not lift, pull or lower the Nailer by the hose.
(12) Do not disconnect air hose from Nailer with
nger on Trigger. The Nailer can re when re-
connected to An air supply.
(13) Handle Nailer correctly. Operate the Nailer
according to this Manual. Never allow the Nailer to
be operated by children, individuals unfamiliar with its
operation or unauthorized personnel.
(14) Never use Nailer for applications other than
those speci ed in this manual.
(15) Never modify or alter a Nailer. Doing so may cause
it to malfunction and personal injuries may result.
(16) Do not remove Dust Cover. Fragments of wire

× average nails driven each minute per Nailer
× air consumption at given air pressure
× safety factor (always 1.2)
Example: 2 Nailers (NV83A2) operating at 100 psi
driving 30 nails per minute
Amount of air required
=2 × 30 × .084 (2.4) × 1.2
=6.0 CFM (ft
3
/min) (173 ltr/min)
After making the calculations as shown above, you
should nd a compressor providing 6.0 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 lled 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/cm
2
).
2
Remove all nails from the Nailer.
3
Connect the air hose and free- re (blank- re) the
Nailer.
The lowered air pressure will be enough to free-
re the Nailer.
Slow speed operation tends to warm up the
moving part.
CAUTION
Do not free- re the Nailer at high pressure.
TESTING THE NAILER
DANGER
Operators and others in work
area MUST wear safety
glasses with side shields
which conforms to ANSI Z87.1
speci cations.
Ordinary eyeglasses do not
provide adequate protection.
WARNING
Never use Nailer unless push lever is
operating properly.
Before actually beginning the nailing work, test the Nailer
by using the checklist below. Conduct the tests in the
following order.
If abnormal operation occurs, stop using the Nailer and
contact a Hitachi authorized service center immediately.

provide adequate protection.
WARNING
Only person who have read
and understand this
MANUAL should operate the
Nailer.
NEVER point tool at yourself
or others in work area.
Keep ngers AWAY from trigger when not
driving nails to avoid accidental discharge.
Know and understand what trigger system
you are using.
Please read and understand “Methods of
Operation” below.
Never place your hands or body closer than 8
inches (200 mm) from ring head when using.
Do not drive nails into other nails; nails can
ricochet and hurt someone.
Do not actuate Nailer unless Nailer is placed
rmly against the workpiece.
In order to avoid double re or unwanted
ejection of a nail due to bouncing of the Nailer
1) do not push Nailer on workpiece with strong
force;
2) take Nailer away from workpiece using
recoil;
3) release trigger quickly when performing
trigger re.
When working close to an edge of a
workpiece or at steep angles, or driving
fasteners into thin workpiece use care to
minimize chipping, splitting or splintering, or
free ight, ricochet or piercing of fasteners,
which may cause injury.
Never drive nails from both sides of a wall
at the same time. Nails can be driven into
and through the wall and hit a person on the
opposite side.
Never use Nailer which is defective or
operating abnormally.
Do not use Nailer as hammer.

This Hitachi nailer has a STANDARD CONTACT TRIP
MECHANISM (Bounce Fire). An OPTIONAL SEQUENTIAL
TRIP MECHANISM kit (SINGLE SHOT) is available as
order part number 876762.
THE STANDARD CONTACT TRIP MECHANISM (Bounce
Fire) is for use where rapid fastener placement is desired
and must be operated in accordance with the following
“METHODS OF OPERATION”.

English
METHODS OF OPERATION
This Nailer is equipped with the push lever and does
not operate unless the push lever is depressed (upward
position).
There are two methods of operation to drive nails with this
Nailer.
They are:
1. Intermittent operation (Trigger re):
2. Continuous operation (Push lever re):
(1) Intermittent operation (Trigger re)
1
Position the nail outlet on the workpiece with
nger o the trigger.
2
Depress the push lever rmly until it is completely
depressed.
3
Pull the trigger to drive a nail.
4
Remove nger from the trigger.
To drive another nail, move the Nailer along the
workpiece and repeat this procedure.
2

(2) Continuous operation (Push lever re)
1
Pull the trigger with the Nailer o the workpiece.
2
Depress the push lever against the workpiece to
drive a nail.
3
Move the Nailer along the workpiece with a
bouncing motion.
Each depression of the push lever will drive a nail.
As soon as the desired number of nails have been
driven, remove nger from the trigger.
Previously pull
the trigger
3
1
WARNING
Keep your nger o the trigger except during
fastening operation, because serious injury
could result if the push lever accidentally
contacts you or others in work area.
Keep hands and body away from the
discharge area. The nailer with contact trip
mechanism may bounce from the 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 nail driving operation. Exercise
caution!
THE OPTIONAL SEQUENTIAL TRIP MECHANISM
(SINGLE SHOT PARTS) is for use where precision
fastener placement is desired and must be operated in
accordance with the following “Method of Operation”.
You must rst depress the push lever (upward position)
where you want to drive a nail and then pull the trigger.
After the each nail is driven, completely release the
trigger and lift the tool o the work surface.
An OPTIONAL SEQUENTIAL TRIP MECHANISM
may reduce the possibility of bodily injury to you or
others in the work area. This is because it is less
likely to drive an unwanted nail if you keep the trigger
pulled and accidentally bump the push lever against
yourself or others. An OPTIONAL SEQUENTIAL TRIP
MECHANISM may also reduce the speed of operation
compared to the standard contact trip mechanism.
NOTE:
Both STANDARD CONTACT TRIP MECHANISM and
OPTIONAL SEQUENTIAL TRIP MECHANISM are
safe if used as described above and accroding to all
warnings and instructions.
19
English
Always handle nails and package carefully.
If dropped, the collated nails may break or come
loose. In such cases, do not use the nails because,
if used in that condition, nail feed may become faulty
and result in missed nails or jamming of the nails.
After nailing:
1) disconnect air hose from the Nailer;
2) remove all nails from the Nailer;
3) supply 5 – 10 drops of Hitachi pneumatic tool
lubricant into the air plug on the Nailer; and
4) open the petcock on the air compressor tank to
drain any moisture.
ADJUSTING THE NAILING DEPTH
To assure that each nail penetrates to the same depth, be
sure that:
1) the air pressure to the Nailer remains constant
