READ ALL INSTRUCTIONS
DANGER
1. ALWAYS WEAR EYE PROTECTOR.
When operating the Nailer, always wear eye protector, and make sure
others in work area wear eye protector, too.
Eye protector 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.
The employer must enforce the use of eye protector by the Nailer
operator and others in work area.
2. NEVER USE BOTTLED GASES.
Never use 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. DO NOT EXCEED 120 psi.
Do not exceed maximum recommended air pressure 120 psi (8.3 bar
8.5 kgf/cm2).
Never connect the Nailer to pressure which potentially exceeds 200 psi
(13.7 bar 14 kgf/cm2) as the Nailer can burst.
4. NEVER POINT NAILER TOWARD YOURSELF OR
ANYONE ELSE.
Always assume the Nailer contains fasteners.
Never point the Nailer toward yourself or anyone else,
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.

caught in moving parts.
Rubber gloves and nonskid footwear are
recommended when working outdoors.
Wear protective hair covering to contain long hair.
12. 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.
13. CHECK PUSH LEVER BEFORE USE.
Make sure the push lever operates properly. (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, otherwise the push lever becomes inoperable.
14. 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.
15. DO NOT LOAD FASTENERS WITH TRIGGER
PULLED OR PUSH LEVER DEPRESSED.
When loading fasteners into the Nailer or when
connecting the air hose,
1) do not pull the trigger;
2) do not depress the push lever; and
3) keep the Nailer pointed downward.
16. KEEP HANDS AND FEET 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.
17. PLACE NAILER PROPERLY ON WORKPIECE.
Do not drive fasteners on top of other fasteners or
with the Nailer at too steep of an angle; the fasteners
can ricochet and hurt someone.
18. BE CAREFUL OF DOUBLE FIRE DUE TO RECOIL.
If the push lever is unintentionally allowed to re-contact
the workpiece following recoil, an unwanted fastener
will be driven.
In order to avoid this undesirable double fire,
1) do not push the Nailer on the workpiece with
strong force;
2) take the Nailer completely away from the
workpiece using recoil, and keep the push lever
away from the workpiece until the next desirable
shot; and
3) pull the trigger and release it QUICKLY when
performing intermittent operation (trigger fire).
19. DO NOT DRIVE FASTENERS INTO THIN
BOARDS OR NEAR CORNERS AND EDGES OF
WORKPIECE.
The fasteners can be driven through or away from the
workpiece and hit someone.
20. 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.
21. 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 off the breaker switch to
ensure there are no live wires.
22. NEVER CARRY NAILER BY HOSE.
23. DO NOT OVERREACH.
Keep proper footing and balance at all times.

䢇Never use non relieving coupler on Nailer.
1. Power source
䡬Use only clean, dry, regulated compressed air as a
power source for this Nailer.
䡬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.”
䡬Moisture or oil in the air compressor may accelerate
wear and corrosion in the Nailer.
Drain daily.
2. Filter-Regulator-Lubricator
䡬Use a regulator with a pressure range of 0 – 120 psi
(0 – 8.3 bar 0 – 8.5 kgf/cm2).
䡬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.
Lubricator .....The lubricator supplies an oil mist to the
Nailer.
Inspect the lubricator before operation to
be sure the supply of lubricant is adequate.
Use pneumatic tool lubricant.
3. Air hose
Air hose must have a minimum working pressure
rating of 150 psi (10.4 bar 10.6 kgf/cm2) or 150% of the
maximum pressure produced in the system, whichever
is higher.
4. Hose coupling
A female coupler must be on the air hose.
The hose coupling (male plug-female coupler) must
remove all pressure from the Nailer when disconnected.
Never use a non relieving coupler on the Nailer.
5. Air consumption

After making the calculations as shown above, you
should find a compressor providing 3.7 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.
䡬Use 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.
䡬Filter-regulator-lubricator units should always be used.
Keep the lubricator filled with pneumatic tool lubricant.
䡬If a lubricator is not available, supply a few drops
(approximately 2 cc (.12 in3)) of pneumatic tool
lubricant into the air plug on the Nailer twice a day.
COLD WEATHER CARE
䡬Do not store the Nailer in a cold weather environment.
Keep the Nailer in a warm area until beginning the
work.
䡬If the Nailer is already cold, bring it in a warm area and
allow the Nailer to warm up before use.
1Reduce the air pressure to 64 psi (4.4 bar
4.5 kgf/cm2).
2Remove all pins from the Nailer.
3Connect 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
䢇Do not free-fire the Nailer at high pressure.

ANSI Z87.1 specifications.
WARNING
䢇Never point Nailer toward yourself or anyone else.
䢇Never carry with finger on trigger.
Remove finger from trigger when not driving pins.
䢇Never place your hands or feet closer than 8 inches
(200 mm) from firing head when using.
䢇Do not drive pins on top of other pins or with
Nailer at too steep of an angle; pins can ricochet
and hurt someone.
䢇In order to avoid double fire 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
fire.
䢇Do not drive pins near corners and edges of
workpiece. Pins can be driven through or away
from workpiece and hit someone.
䢇Never drive pins from both sides of a wall at the
same time. Pins can be driven into and through the
wall and hit a person on the opposite side.
䢇Never use Nailer which is defective or operating
abnormally.
䢇Do not use Nailer as hammer.
䢇Disconnect air hose from Nailer when:
1) it is not in use;
2) leaving work area;
3) moving it to another location; and
4) handing it to another person.
This nailer has a SEQUENTIAL TRIP MECHANISM.
METHOD OF OPERATION
This Nailer is equipped with the push lever and does not
operate unless the push lever is depressed (upward
position).
To drive pins with this nailer:
1Position the outlet on the workpiece with finger off the
trigger.
2Depress the push lever firmly until it is completely
depressed.
3Pull the trigger to drive a pin.
4Remove finger from the trigger.
To drive another pin, move the Nailer along the
workpiece and repeat this procedure.
WARNING
䢇Keep your finger off the trigger except during
fastening operation, because serious injury could
result if the push lever accidentally contacts you or
others in work area.
䢇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.
䢇Some types of loaded pins can spark out of the
muzzle during a pin driving operation. Exericise
caution!
THE 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 first depress the push lever (upward posi-
tion) where you want to drive a pin and then pull the

possibility of bodily injury to you or others in the work
area. This is because it is less likely to drive an un-
wanted pin if you keep the trigger pulled and acciden-
tally bump the push lever against yourself or others.
NOTE:
䢇Always handle pins and package carefully.
If dropped, the collated pins may break or come loose.
In such cases, do not use the pins because, if used in
that condition, pin feed may become faulty and result
in missed pins or jamming of the pins.
䢇After fastening:
1) disconnect air hose from the Nailer;
2) remove all pins from the Nailer;
3) supply a few drops (approximately 2 cc (.12 in3)) of
pneumatic tool lubricant into the air plug on the
Nailer; and
4) open the petcock on the air compressor tank to
drain any moisture.
