1. OPERATORS AND OTHERS IN WORK AREA
MUST WEAR EYE PROTECTION (SAFETY
GLASSES WITH SIDE SHIELDS).
When operating the Nailer, always wear
safety glasses with side shields, and
make sure others in work area wear
safety glasses, too.
Safety glasses must conform to the
requirements of American National
Standards Institute, ANSI Z87.1 and
provide protection against flying particles
both from the front and side.
Ordinary eyeglasses do not provide
adequate protection.
The employer must enforce the use of
safety glasses by the Nailer operator and
others in work area.
WARNING
3. NEVER POINT TOOL AT YOURSELF OR OTHERS
IN WORK AREA.
Always assume that the Nailer contains
fasteners.
Never point the Nailer toward yourself or
others, whether it contains fasteners or
not.
If fasteners are mistakenly driven, it can
lead to severe injuries.
Never engage in horseplay with the
Nailer.
Respect the Nailer as a working
implement.
2. NEVER USE REACTIVE GASES OR OTHER
BOTTLED GASES. EXPLOSION MAY OCCUR.
Never use reactive gases such as

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, touching
the Push Lever, 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 metabo HPT 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
metabo HPT 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 metabo HPT 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 metabo HPT.
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 120 psi (8.3 bar 8.5 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) Before starting work, check the nailing operation
switching device.
This metabo HPT nailer includes a nailing operation
switching device.
Before starting work, check the setting of the
operation switching device.
If the switching device is not set properly, the Nailer
will not operate correctly.
(2) Always select the switching device that is
appropriate to the application and the training of
the operator.
(3) When switching between SINGLE SEQUENTIAL
and CONTACT, disconnect the air hose and
remove all nails.
(4)
When the hook is attached, operate only with
SINGLE SEQUENTIAL ACTUATION MECHANISM
and not with CONTACT ACTUATION MECHANISM.

English
(5) Be careful of double fire 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. In “CONTACT
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 fire,
○ Intermittent operation (Trigger fire)
1 Set the switching device to SINGLE
SEQUENTIAL ACTUATION MECHANISM.
2 Pull the trigger rapidly and firmly.
○ Continuous operation (Push lever fire)
1 Set the switching device to CONTACT
ACTUATION MECHANISM.
2 Do not press the Nailer against the wood with
excessive force.
3 Separate the Nailer from the wood as it recoils
after nailing.
4) keeping face and body parts away from the Nailer.
(6) 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.
(7) 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.
(8) 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.
(9) 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.
(10)Keep hands and body away from firing head
during use. Never place your hands or feet closer
than 8 inches (200 mm) from the firing head. A
serious injury can result if the fasteners are deflected
by the workpiece, or are driven away from the point of
entry.
(11) 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 flight, ricochet or
piercing of fasteners, which may cause injury.
(12)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.
(13)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).
(14) Check for live wires. Avoid the risk of severe
electrical shock by checking for live electrical wires
that may be hidden by walls, floors or ceilings. Turn
offthe breaker switch to ensure there are no live
wires.
(15)Do not lift, pull or lower the Nailer by the hose.
(16)Do not disconnect air hose from Nailer with
finger on Trigger. The Nailer can fire when re-
connected to An air supply.
(17) 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.
(18)Never use Nailer for applications other than
those specified in this manual.
(19) Never modify or alter a Nailer. Doing so may cause
it to malfunction and personal injuries may result.
(20)Disconnect the air hose when affixing the hook.
(21)Do not affix the hook on high or unstable
locations. Also, do not affix it to the body,
clothing, belt or other personal items.

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: 2 Nailers operating at 100 psi driving 30
nails per minute
Amount of air required
=2 × 30 × .088 (2.5) × 1.2
=6.3 CFM (ft3/min) (180 ltr/min)
After making the calculations as shown above, you
should find a compressor providing 6.3 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 metabo HPT 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 metabo HPT pneumatic
tool lubricant.
○ If a lubricator is not available, supply 5 – 10 drops of
metabo HPT 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.
Slow speed operation tends to warm up the
moving part.
CAUTION
●
Do not free-fire the Nailer at high pressure.
