PRECAUTIONS ON USING STAPLER
1. Safe operation through correct usage
This tool was designed for driving staples into wood
and similar materials. Use it for its intended purpose
only.
2. Make sure air pressure is within the rated range of
air pressure.
Please make sure that the air pressure is within a
range of 4.9 bar – 8.3 bar (70 ~ 120 psi.), and that the
air which is used is clean and dry. If the air pressure
is greater than 8.3 bar (120 psi.), the life of the power
tool will be shortened and dangerous conditions
could develop. Tools shall not be connected to
pressure which potentially exceeds 14 bar (200 psi.).
3. Never operate the equipment with high-pressure
gases other than compressed air.
Never use carbon dioxide, oxygen or another gas
from pressurized containers under any
circumstances.
4. Be careful of ignition and explosions.
Since sparks may fly during stapling, it is dangerous
to use this tool near lacquer, paint, benzine, thinner,
gasoline, gas, adhesives and similar inflammable
substances as they may ignite or explode. Under no
circumstances should this tool therefore be used in
the vicinity of such inflammable material.
5. Always wear eye protection (protective goggles).
When operating the power tool, always wear eye
protection, and ensure that surrounding people wear
eye protection too.
The possibility of fragments of the staples that were
not properly hit entering the eye is a threat to sight.
Eye protection can be bought at any hardware store.
Always wear eye protection while operating this
tool. Use either eye protection or a wide vision mask
over prescription glasses.
Employers should always enforce the use of eye
protection equipment.
6. Protect your ears and head.
When engaged in stapling work please wear ear
mufflers and head protection. Also, depending on
condition, ensure that surrounding people also wear
ear mufflers and head protection.
7. Pay attention to those working close to you.
It would be very dangerous if staples that were not
properly driven in should hit other people. Therefore,
always pay attention to the safety of the people
around you when using this tool. Always make sure
that nobody’s body, hands or feet are close to the
staple outlet.
8. Never point the staple outlet towards people.
Always assume the tool contains fasteners.
If the staple outlet is pointed towards people, serious
accidents may be caused if you mistakenly discharge
the tool. When connecting and disconnecting the
hose, during staple loading or similar operations, be
sure the staple outlet is not pointed towards anyone
(including yourself). Even when no staples are loaded
at all, it is dangerous to discharge the tool while
pointing it at someone, so never attempt to do so. No
horseplay. Respect the tool as a working implement.

9. Before using the power tool, check the push lever.
Before using the power tool make sure to check that
the push lever and valve operate properly. Without
staples loaded into the power tool, connect the hose
and check the following. If the sound of operation
occurs this indicates a fault, so in such a case do not
use the power tool until it has been inspected and
repaired.
䡬 If merely pulling the trigger causes operating
sound of drive bit movement occur, the power
tool is faulty.
䡬 If merely pushing the push lever against the
material to be stapled causes the sound of drive
bit movement to occur, the power tool is faulty.
Furthermore, with regard to the push lever, please
note that it must never be modified or removed.
10. Use specified staples only.
Never use staples other than those specified and
described in these instructions.
11. Be careful when connecting the hose.
When connecting the hose and loading staples in
order not to fire the tool by mistake, make sure of the
followings.
䡬 Do not touch the trigger.
䡬 Do not allow the firing head to contact with any
surface.
䡬 Keep the firing head down.
Strictly observe the above instructions, and always
make sure that no part of the body, hands or
legs is ever in front of the staple outlet.
12. Do not carelessly place your finger on the trigger.
Do not place your finger on the trigger except when
actually stapling. If you carry this tool or hand it to
someone while having your finger on the trigger,
you may inadvertently discharge a staple and thus
cause an accident.
13. Press the staple outlet firmly against the material to
be stapled.
When driving in staples, press the staple outlet
firmly against the material to be stapled. If the outlet
is not applied properly, the staples may rebound.
14. Keep hands and feet away from the firing head
when using.
It is very dangerous for a staple to hit the hands or
feet by mistake.
15. Beware of the tool’s kickback
Do not approach the top of the tool with your head,
etc. during operation. This is dangerous because the
tool may recoil violently if the staple currently being
driven in comes into contact with a previous staple
or a knot in the wood.
16. Take care when stapling thin boards or the corners
of wood.
When stapling thin boards, the staples may pass
right through, as may also be the case when stapling
the corners of wood due to deviation of the staples.
In such cases, always make sure that there is no one
(and nobody’s hands or feet; etc.) behind the thin
board or next to the wood you are going to staple.
17. Simultaneous stapling on both sides of the same
wall is dangerous
Under no circumstances should stapling be
performed on both sides of a wall at the same time.
This would be very dangerous since the staples
might pass through the wall and thus cause injuries.
18. Do not disconnect the hose with your finger on the
trigger.
If you disconnect the hose with your finger on the
trigger, the next time the hose is connected, there
is a danger that the power tool will fire a staple
spontaneously, or operate incorrectly.
19. Disconnect the hose and take out any staples left in
the magazine after use.
Disconnect tool from air before doing tool
maintenance, cleaning a jammed fastener, leaving
work area, moving tool to another location, or after
use. It is very dangerous for a staple to be fired by
mistake.
20. When removing a staple which has become stuck,
make sure to first of all disconnect the hose and
release compressed air.
When removing a staple which has become stuck in
the staple outlet, first of all make sure to disconnect
the hose and release compressed air inside the
power tool.
Accidental firing of the staple could be very
dangerous.
21. A female plug (air socket) should not be used in the
body.
If a female plug is installed in the body, the
compressed air sometimes can not be drawn when
the hose is disconnected so avoid this.
The tool and air supply hose must have a hose
coupling such that all pressure is removed from the
tool when the coupling joint is disconnected.

BEFORE USE
1. Check the air pressure
CAUTION:
The air pressure must be constantly maintained at 4.9
– 8.3 bar (70 – 120 psi.).
Adjust the air pressure between 4.9 to 8.3 bar (70 ~ 120
psi.) according to the diameters and length of staples
and hardness of the wood being stapled. Pay special
attention to the output pressure, capacity, and piping
on the air compressor, so that air pressure does not
exceed the specified limit. Note that excessive pressure
may affect overall performance, service life, and safety.
2. Lubrication
(1) Prior to operating this stapler, be sure to provide an air
set between the air compressor and this device.
Lubrication through the air set offers smooth operation,
extended service life, and anticorrosion.
Adjust the oiler so that a single drop of oil is supplied
at intervals of 5 to 10 stapling cycles.
(2) It is recommended using the recommended oil (SHELL
TONNA). Other applicable oils are listed. Never mix
two or more types of different oils.
3. Load staples
(1) Shift the staple feeder to the rear and engage it with
the groove of the staple guide.
(2) Insert series of staples from the top and feed manually
to the front. Load separated staples so that they are
packed within the magazine cover (Fig. 1)
(3) After loading staples, shift the staple feeder to the rear
to disengage it from the groove and move the staple
feeder so that it secures the staples.

HOW TO USE THE STAPLER
CAUTIONS:
䡬 Never use the head or body of this device as a
hammer.
䡬 Take precautions to ensure the safety of persons in
the vicinity during operation.
1. Stapling procedures
(1) Method of intermittently driving staples (single shot)
The single-contact change lever is in the single shot
position (See Fig. 3)
This stapler includes a single shot structure to allow
firing of a single staple by pushing down the push
lever and pulling the trigger (see Fig. 2).
CAUTION:
䡬 [Method of intermittently driving staples (single shot)]
explained here is not [Sequential fire]. When Singlecontact Change Lever is at the Single shot position, if
the push lever is pushed up in a state where the trigger
is pulled, only one piece of staple in the staple outlet
is fired: Be careful!
In the event it is used by Sequential fire, use the
Sequential Trip Mechanism Kit of OPTIONAL
ACCESSORY.
䡬 If you do not pull the trigger quickly and crisply while
in the single shot mode, the stapler will bounce and
shoot several staples instead of just one. To avoid this,
be sure to pull the trigger quickly and crisply.

CAUTION:
Exercise care when stapling corners of lumber. When
continuous stapling corners of lumber, a staple may
go astray or break through the corner.
NOTES:
䡬 Precautions on no-load operation
Sometimes stapling will continue after driving in all
staples previously contained in the magazine.
This is termed “no-load operation”. Such operation
may deteriorate the bumper, magazine, and staple
feeder.
To avoid no-load operation, occasionally confirm the
amount of remaining staples. On the other hand, all
staples should be removed after using this stapler.
䡬 After completing operation, put into the body about
2cc oil through the hose joint to protect the tool from
rust.
䡬 Under low temperature conditions, the machine
sometimes does not operate correctly. Always operate
the machine at the appropriate ambient temperature.
2. Adjusting the staple-driving depth
CAUTIONS:
When making adjustments, be sure remove your
finger from the trigger. When making adjustments, be
sure that the staple outlet is not facing downward and
that body parts or other persons are not in the path of
the staple outlet.
䡬 Adjusting the adjuster (Fig. 6)
Carry out test driving. If the staples are too deep,
turn the adjuster to the shallow side (
mark).
If the staple depth is too shallow, turn the adjuster
to the deep side (
mark) (see Fig. 6, 7).
Depth is changed 1 mm with each rotation of the
adjuster.
Fig. 6
Fig. 7
NOTES:
䡬 When adjusting the adjuster, it does not rotate more
than 3 mm from the deepest point where a staple goes
down. Do not rotate the adjuster by force beyond that
point.
䡬 The staple-driving depth can also be adjusted by
changing the air pressure used. Carry this out together
with movement of the adjuster. Using a high air
pressure that does not match the staple-driving
resistance will shorten the life of this stapler.
3. Changing the exhaust direction.
The direction of the exhaust vent can be changed
within 360° by turning the top cover. (Fig. 8).

䡬 At the time of assembly, make sure that the push lever
is properly inserted into the blade guide’s guiding
section. (Fig. 11)
Fig. 11
䡬 After assembly, check and make certain that the push
lever can move up and down smoothly.
NOTE:
䡬 If the driver blade’s tip is worn out, staples tend to get
jammed. Request repair service if the staples get
jammed frequently.
2. Check on mounting screws for each part
At regular intervals check every part for loose
mounting screws and whether or not there are any
air leaks. Retighten any loose screws. Operating the
equipment with loose screws untightened will incur
a hazard.
3. Inspecting the push lever
Check if the push lever can slide smoothly. (Fig. 16)
Clean up the sliding area of the push lever and use the
provided oil for lubrication from time to time.
Lubrication enables smooth sliding and
simultaneously serves to prevent the formation of
rust.
Fig. 12
4. Inspecting the magazine
䡬 Clean up the magazine from time to time.
Remove the dust, wood chips, etc., accumulated in it.
䡬 Lubricate the staple feeder’s spring sometimes.
Pull the staple feeder backward, and lubricate the
spring from the back in a state where the staple feeder
is hooked onto the magazine’s groove. (Fig. 13)

coat of the lubricant to the steel parts to avoid rust.
䡬 Do not store the Stapler in a cold weather environment.
Keep the Stapler in a warm area.
䡬 When not in use, the Stapler should be stored in a
warm and dry place.
Keep out of reach of children.
COMPRESSOR
CAUTION:
When the maximum, operating pressure of the air
compressor exceeds 8.3 bar (120 psi.), be sure to
provide a reducing valve between the air compressor
and stapler. Then, adjust the air pressure within the
operating range of 4.9 – 8.3 bar (70 – 120 psi.). If the air
set is installed, lubrication is also possible, thus
providing additional convenience.
OILER-FILTER-REDUCING VALVE (Air Set)
