SAFETY INSTRUCTIONS
DANGER!
1) Be sure to put goggles on before operation
Since a fastener red wrongly through careless handling can spring
out or you are always exposed to danger that can be caused by dust
and extraneous substances dispersed by exhausted air, you must
always wear goggles for operation. Goggles should meet requirements of
ANSI Z89.1-1997 and be able to protect both the front and the sides. An
employer has responsibility for having workers and all the other persons
wear protective equipment in a workshop.
2) Put on hearing protective equipment in certain working environment.
In working environment exposed to loudness which may result in
hearing loss, an employer (management) must provide hearing
protection equipment to a user and others in the workshop and a worker

USER MANUAL 3
must wear it if necessary.
3) Never use any power source but compressed air.
As this tool is designed and manufactured to operate using air
pressure that is generated by an air compressor authorized by a safety
certication authority, you cannot use any kind of gas combustible
gases such as oxygen and acetylene except this. Otherwise, it may
not only cause mechanical trouble but also malfunction or explosion,
resulting in iniction of fatal injury on a user or those around him or her.
4) Use it within the optimum range of air pressure.
This tool is designed to operate within a range of pressure between
58 psi and 100 psi (or between 4 bar and 7 bar). Connect this tool to a
pressure controllable device so that you can work under xed pressure.
When operating this tool, never use it under pressure of 120psi (8bar)
and over. this tool can not connected to pressure higher than 120 psi (or
8 bar) , or wil damaged the parts.
5) Don’t use it near inammables (combustibles).
Never operate this tool near inammables (such as thinner and
gasoline). Combustible gas from such materials can be sucked into
a compressor and compressed together with air, possibly resulting in
explosion.
6) Be careful not to aim or re it toward yourself or any other person in
any case.
You should be careful not to aim it toward yourself or any other person
in any case whether the tool is loaded with fasteners or not. Then, even
if malfunction or undesired ring occurs, you can minimize damage
caused by the red fasteners. Otherwise, it may result in serious injury.
7) Never touch the trigger except when this tool operates for work.
Never touch the trigger except when air is connected to this tool,
which operates for work. It is especially very dangerous to change the
position or move around during operation with your nger xed
on the trigger, and you may not do any similar action. Otherwise
possible carelessness may result in iniction of serious injury on a
user or those around him or her.

WARNING!
8) Connect a proper connector to this tool correctly.
The connector for this tool should never have pressure kept when air
supply is cut off. If an improper part is applied, then the tool can oper-
ate due to pressure left within it even after the airline is disconnected
possibly resulting in injury.
9) Disconnect the air line and empty the fasteners out of the container in
case that the tool is not used.
Be sure to cut off air supply and empty the fastener container when the
work is completed or when you move to another workshop, maintain,
disassemble, or repair this tool, or clear jam. Make sure that the airline
is disconnected in loading the container with fasteners again.
CAUTION:
10) Make sure that each fastener is locked tightly.
The tool can be damaged if you use it with each fastener loosened, or
screws or bolts assembled wrongly. Make sure that all screws and bolts
are assembled correctly and tightly before using the tool.
11) Never let a worker remove or manipulate a safety device, or
recompose the tool at his or her discretion.
If you remove a safety device, or manipulate or recompose the tool at
will, it can cause a drop in performance and breakdown of the tool and
result in injury due to mechanical trouble and malfunction.
12) Be sure to disconnect the air line and empty fasteners out of the
container if the tool is not used.
You must disconnect the air line and empty the fastener container when
the work is completed or suspended, when you go out of a workshop,
when you move or transfer the tool, or on other occasions.
13) Stick the muzzle correctly to the target plane for drive a fastener.
If correct drive a fastener is not implemented on the target plane, the
red fastener can spring out, possibly resulting in injury.
14) You are prohibited from using the tool for other purposes than drive
a fastener and from throwing or dropping it.

USER MANUAL 5
The resultant shock can cause damage to main parts or malfunction,
possibly resulting in injury.
15) Never drive a fastener on hard or thin objects, an edge of the target
surface or a fastener crown already driven.
Otherwise, the fastener fails to be driven in but springs out, thus
inicting an injury on a worker or those around him or her.
16) Conduct operations in an upright and safe position all the time.
Long-time work in an unstable and wrong position may put excessive
stress on the body, possibly resulting in an injury.
17) When the temperature falls below zero, it is important to note that
you should keep the tool warm in a safe and convenient way.
If you fail to do this, make the tool get warm according to the following
procedure.
1) Control air pressure in the range of 40psi to 70psi.
2) Remove all the fasteners loaded in the tool.
3) Connect the airline to the tool and try mock drive a fastener.
- Keep pressure low enough to operate the tool in a proper way.
- Operate it slowly to let the actuator get warm.
- Piston operation helps bumper and O-ring maintain the original
elasticity.
APPLICATIONS

INSTRUCTIONS FOR OPERATION
.BE SURE TO READ THE SAFETY INSTRUCTION BEFORE USING
THIS TOOL
.PREPARATIONS
1) Be sure to put on personal protective equipment for example
goggles, earplugs, safety cap before using this tool.
2) Be sure to use an air compressor authorized by the safety certi-
cation authority as a pressure source for operating this tool within the
optimum range of pressure (58~100psi).
3) Make sure that this tool has no trouble about the safety device, the
trigger, fasteners such as bolts, and so on.
4) Inject three or four drops of oil used exclusively for a tool into the air
plug before using this tool. (Do this regularly once a day if possible.)
5) Check the airline and the air connector for damage and don’t use
longer airline than necessary (over 17ft).
PRELIMINARY CHECKUP
1) To give a checkup to the tool, adjust the operating pressure to 58 psi
(4 bar) before air connection.
2) Keep pressure low as far as it may cause no trouble in operation
within the optimum range of pressure according to hardness of the
working plane and length of fasteners.
LOADING NAILS
WARNING!
Turn the muzzle downward and never pull the trigger in loading or
unloading nails.
1) Pull the magazine backward with the click lever pressed.

.CLEARING A JAM
If jam occurs during the nailing process,
clear it according to the following
procedure.
1) Disconnect the air line from the tool.
2) Unload nails left in the magazine.
3) Open the guide cover B.
4) Use a long nose to remove a nail
caught in.
CAUTION:
- After clearing jam, make sure that the product has no trouble before
using it.
- If jam or other factors damage main parts, it can prevent normal
operation.
- If any trouble occurs, stop using the tool and ask a nearby A/S center
or a distributor for A/S.
INSPECTING THE MAGAZINE
1) Disconnect the air line from the tool.
2) Inspect if the inside of the magazine is cleared or damaged. (Dust or
alien substances such as pieces of wood in the operation body of the
pusher within the magazine can prevent smooth operation.)

USER MANUAL 9
STORING
1) When not in use for an extended period, apply a thin coat of the
lubricant to the steel parts to avoid rust.
2) Do not store the tool in a cold weather environment. Keep the tool in
a warm area.
3) When not in use, the tool should be stored in a warm and dry place.
4) Keep out of reach of children.
5) All quality tools will eventually require servicing or replacement of
parts because of wear from the normal use.
