SAFETY
IMPORTANT SAFETY INSTRUCTIONS - FOR USING NAILERS
INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS
●
General
To reduce the risks of electric shock, fi re, and injury to persons, READ ALL THE INSTRUCTIONS BEFORE USING
THE TOOL.
DANGER
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 fl ying 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.
2. NEVER USE REACTIVE GASES OR OTHER
BOTTLED GASES. EXPLOSION MAY OCCUR.
Never use reactive gases such as
oxygen, combustible gases or any other
bottled gases as a power source for the
Nailer.
Use of the above gases is dangerous, as
the Nailer will explode.
Use only clean, dry, regulated
compressed air.
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.
4. DO NOT PLACE FINGER ON TRIGGER AND KEEP
FINGERS AWAY FROM TRIGGER WHEN NOT
DRIVING FASTENERS TO AVOID ACCIDENTAL
DISCHARGE.
Never carry the Nailer with fi nger on Trigger since
you could drive a fastener unintentionally and injure
yourself or someone else.
Always carry the Nailer by the handle only.
5. KNOW AND UNDERSTAND WHAT TRIGGER
SYSTEM YOU ARE USING.
Read and understand section titled “METHODS OF
OPERATION.” (pages 17 – 19)
6. DO NOT MAKE CONTACT WITH SAFETY TIP
(PUSH LEVER) WHEN NOT DRIVING FASTENERS.

English
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, fi re, and injury to persons.
(2) Do not operate the Nailer in explosive
atmospheres, such as in the presence of
fl 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 infl 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 off before connecting to the air supply. Do
not carry the Nailer with your fi 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, 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 fl ying objects.
Head protection shall conform to ANSI Z89.1,
"American National Standard for Industrial Head
Protection."
(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 defl 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 off . Any Nailer that cannot be
controlled with the switch is dangerous and must be
repaired.
7
English
(5) 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. 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 re,
○
Intermittent operation (Trigger re)
1
Set the switching device to SINGLE
SEQUENTIAL ACTUATION MECHANISM.
2
Pull the trigger rapidly and rmly.
○
Continuous operation (Push lever re)
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.
SAFETY — Continued
WARNING
(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 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.
(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 ight, 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, oors or ceilings. Turn
off the 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
nger on Trigger. The Nailer can re 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 speci ed 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 affi xing the hook.
(21) Do not affi x the hook on high or unstable
locations. Also, do not affi x it to the body,
clothing, belt or other personal items.

= 7.1 CFM (ft 3/min) (202 ltr/min)
After making the calculations as shown above, you
should nd a compressor providing 7.1 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 lled 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/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-fi re the Nailer at high pressure.
TESTING THE NAILER
DANGER
●

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.
●
Disconnect air hose from Nailer when:
1) it is not in use;
2) leaving work area;
3) elevating, lowering or otherwise moving it to
another location;
4) handing it to another person;
5) When removing the screw.

This metabo HPT nailer is equipped with a nailer
operation switching device.
Use SINGLE SEQUENTIAL ACTUATION MECHANISM or
CONTACT ACTUATION MECHANISM in accordance with
the work to be performed.
Explanation of the various nailing operations
○
SINGLE SEQUENTIAL ACTUATION MECHANISM:
First, press the push lever against the workpiece;
next, pull the trigger to drive the nail.
After nailing once, nailing will not be possible again
until the trigger is released and pressed again.
○
CONTACT ACTUATION MECHANISM: First, press
the push lever against the workpiece; next, pull the
trigger to drive the nail. Or,
pull the trigger; next, press the push lever against the
workpiece to drive the nail.
If the trigger is held back, a nail will be driven each
time the push lever is pressed against the workpiece.
PREVENTIVE MECHANISM FOR
UNLOADED OPERATION
The machine employs a preventive mechanism for
unloaded operation.
The machine enters a state where the push lever stopper
runs into the upper part of the push lever and the push
lever cannot be pushed up. This takes place when the
magazine is not loaded with nails or when the remaining
number of nails becomes less than 5 (This diff ers by the
type of nail).
Load the nails immediately if you come across with such a
condition during operation.

English
The SINGLE SEQUENTIAL ACTUATION MECHANISM
is for use where precision fastener placement is desired.
The SINGLE SEQUENTIAL ACTUATION MECHANISM
may reduce the possibility of bodily injury to you or others
in the work area compared to the CONTACT ACTUATION
MECHANISM. 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.
The SINGLE SEQUENTIAL ACTUATION MECHANISM
may also reduce the speed of operation compared
to the CONTACT ACTUATION MECHANISM. The
SINGLE SEQUENTIAL ACTUATION MECHANISM is
recommended to inexperienced users.
NOTE
●
If all warnings and instructions are followed, safe
operation is possible with all two systems: SINGLE
SEQUENTIAL ACTUATION MECHANISM and
CONTACT ACTUATION MECHANISM.
●
Always handle nails and package carefully. If nails
are dropped, collating plastic may be broken.
●
After nailing:
1) disconnect air hose from the Nailer;
2) remove all nails from the Nailer;
3) supply 5 – 10 drops of metabo HPT 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
WARNING
●
Disconnect the air hose from the nailer
before turning the adjuster.
To assure that each nail penetrates to the same depth, be
sure that:
1) the air pressure to the Nailer remains constant
(regulator is installed and working properly), and
2) the Nailer is always held fi rmly against the workpiece.
If nails are driven too deep or shallow into the workpiece,
adjust the nailing in the following order.
1
DISCONNECT AIR HOSE FROM NAILER.
