1. SAFETY INSTRUCTIONS
WARNING:
TO AVOID SEVERE PERSONAL INJURY OR PROPERTY DAMAGE
BEFORE USING THE TOOL, READ CAREFULLY AND UNDERSTAND THE FOLLOWING
“SAFETY INSTRUCTIONS”. FAILURE TO FOLLOW WARNINGS COULD RESULT IN DEATH
OR SERIOUS INJURY.
PRECAUTIONS ON USING THE TOOL
1. WEAR SAFETY GLASSES OR GOGGLES
Danger to the eyes always exists due to the possibility of dust being blown up by the
exhausted air or of a fastener flying up due to the improper handling of the tool. For these
reasons, safety glasses or goggles shall always be worn when operating the tool.
The employer and/or user must ensure that proper eye protection is worn. Eye protection
equipment must conform to the requirements of the American National Standards Institute,
ANSI Z87.1 (Council Directive 89/686/EEC of 21 DEC. 1989) and provide both frontal and
side protection.
NOTE: Non-side shielded spectacles and face shields alone do not provide adequate
protection.
2. EAR PROTECTION MAY BE REQUIRED IN SOME ENVIRONMENTS
As the working condition may include exposure to high noise levels which can lead to
hearing damage, the employer and user should ensure that any necessary hearing
protection is provided and used by the operator and others in the work area.
3. DO NOT USE ANY POWER SOURCE EXCEPT AN AIR COMPRESSOR
The tool is designed to operate on compressed air. Do not operate the tool on any other
highpressure gas, combustible gases (e.g., oxygen, acetylene, etc.) since there is the
danger of an explosion. For this reason, absolutely do not use anything other than an air
compressor to operate the tool.
4. OPERATE WITHIN THE PROPER AIR PRESSURE RANGE
The tool is designed to operate within an air pressure range of 60 to 100 p.s.i. (4 to 7 bar.)
The pressure should be adjusted to the type of the work being fastened. The tool shall never
be operated when the operating pressure exceeds 120 p.s.i. (8 bar.)
Never connect the tool to air pressure which potentially exceeds 200 p.s.i. (14 bar) as the
tool can burst.
5. DO NOT OPERATE THE TOOL NEAR A FLAMMABLE SUBSTANCE
Never operate the tool near a flammable substance (e.g., thinner, gasoline, etc.). Volatile
fumes from these substances could be drawn into the compressor and compressed together
with the air and this could result in an explosion.
6. DO NOT USE A WRONG FITTINGS
The connector on the tool must not hold pressure when air supply is disconnected. If a
wrong fitting is used, the tool can remain charged with air after disconnecting and thus will
be able to drive a fastener even after the air line is disconnected, possibly causing injury.
7. DISCONNECT THE AIR SUPPLY AND EMPTY THE MAGAZINE WHEN THE TOOL IS
NOT IN USE
Always disconnect the air supply from the tool and empty the magazine when operation has
been completed or suspended, when moving to a different work area, adjusting,
disassembling, or repairing the tool, and when clearning a jammed fastener.

5
8. INSPECT SCREW TIGHTNESS
Loose or improperly installed screws or bolts cause accidents and tool damage when the
tool is put into operation. Inspect to confirm that all screws and bolts are tight and properly
installed prior to operating the tool.
9. DO NOT TOUCH THE TRIGGER UNLESS YOU INTEND TO DRIVE A FASTENER
Whenever the air supply is connected to the tool, never touch the trigger unless you intend
to drive a fastener into the work. It is dangerous to walk around carrying the tool with the
trigger pulled, and this and similar actions should be avoided.
10. NEVER POINT THE DISCHARGE OUTLET TOWARD PECPLE
If the discharge outlet is pointed toward people, serious accidents may be caused when
misfiring. Be sure the discharge outlet is not pointed toward people when connecting and
disconnecting the hose, loading the fasteners or similar operations.
11. USE SPECIFIED FASTENERS (SEE PAGE 7)
The use of fasteners other than specified fasteners will cause the tool malfunction. Be sure
to use only specified fasteners when operating the tool.
12. PLACE THE DISCHARGE OUTLET TO THE WORK PROPERLY
Failure to place the discharge outlet of the nose in a proper manner can result in a fastener
flying up and is extremely dangerous.
13. KEEP HANDS AND BODY AWAY FROM THE DISCHARGE OUTLET
When loading and using the tool, never place a hand or any part of body in fastener
discharge area of the tool. It is very dangerous to hit the hands or body by mistake.
14. DO NOT DRIVE FASTENERS CLOSE TO THE EDGE AND CORNER OF THE WORK
AND THIN MATE RIAL
The workpiece is likely to split and the fastener could fly free and hit someone.
15. DO NOT DRIVE FASTENERS ON THE TOP OF OTHER FASTENERS
Driving fasteners of the top of other fasteners may cause deflection fasteners which could
cause injury.
16. REMOVING THE FASTENERS AFTER COMPLETING OPERATION
If fasteners are left in the magazine after the completion of operation, there is the danger of
a serious accident occurring prior to the resumption of operation, should the tool be handled
carelessly, or when connecting the air fitting. For this reason, always remove all fasteners
remaining in the magazine after completion of the operation.
17. CHECK OPERATION OF THE CONTACT TRIP MECHANISM FREQUENTLY IN CASE OF
USING A CONTACT TRIP TYPE TOOL
Do not use the tool if the trip is not working correctly as accidental driving of a fastener may
result. Do not interfere with the proper operation of the contact trip mechanism.

6
18. WHEN USING THE TOOL OUTSIDE OR ELEVATED PLACE
When fastening roofs or similar slanted surface, start fastening at the lower part and
gradually work your way up. Fastening backward is dangerous as you may loose your foot
place.
Secure the hose at a point close to the area you are going to drive fasteners. Accidents may
be caused due to the hose being pulled inadvertently or getting caught.
19. NEVER USE THE TOOL WHICH IS DEFECTIVE OR PERFORMS ABNORMALLY
20. NEVER ACTUATE THE TOOL INTO FREE SPACE
This will avoid any hazard caused by free flying fasteners and excessive strain of the tool.
OBSERVE THE FOLLOWING GENERAL CAUTION IN ADDITION TO
THE OTHER WARNINGS CONTAINED IN THIS MANUAL
•Do not use the tool as a hammer.
•Always carry the tool by handle, never carry the tool by the air hose.
•The tool must be used only for the purpose it was designed.
•Never clamp the trigger in locked operation position.
•Keep the tool in a dry place out of reach of children when not in use.
•Do not use the tool without Safety Warning label.

3. AIR SUPPLY AND CONNECTIONS
Read section titled “SAFETY INSTRUCTIONS”.
DO NOT USE ANY POWER SOURCE EXCEPT AN AIR COMPRESSOR
The tool is designed to operate on compressed air. Do not operate the tool on any other
highpressure gas, combustible gases (e.g., oxygen, acetylene, etc.) since there is the
danger of an explosion. For this reason, absolutely do not use anything other than an air
compressor to operate the tool.
OPERATE WITHIN THE PROPER AIR PRESSURE RANGE
The tool is designed to operate within an air pressure range of 60 to 100 p.s.i. (4 to 7 bar.)
The pressure should be adjusted to the type of the work being fastened. The tool should
never be operated when the operating pressure exceeds 120 p.s.i. (8 bar.)
DO NOT OPERATE THE TOOL NEAR A FLAMMABLE SUBSTANCE
Never operate the tool near a flammable substance (e.g., thinner, gasoline, etc.). Volatile
fumes from these substances could be drawn into the compressor and compressed together
with the air and this could result in an explosion.
DO NOT USE A WRONG FITTINGS
The connector on the tool must not hold pressure when air supply is disconnected. If a
wrong fitting is used, the tool can remain charged with air after disconnecting and thus will
be able to drive a fastener even after the air line is disconnected, possibly causing injury.
DISCONNECT THE AIR CHUCK WHEN THE TOOL IS NOT IN USE
Always disconnect the air chuck from the tool when operation has been completed or
suspended, when moving to a different work area, adjusting, disassembling, or repairing the
tool, and when clearing a jammed fastener.
FITTINGS: Install a male plug on the tool which is free flowing and which
will release air pressure from the tool when disconnected from the supply
source.
HOSES: Hose has a min. ID of 1/4” (6 mm) and max. length of no more
than 17” (5 meters).
The supply hose should contain a fitting that will provide “quick
disconnecting” from the male plug on the tool.
SUPPLY SOURCE: Use only clean regulated compressed air as a power
source for the tool.
3-PIECE AIRSET (Air filter, Regulator, Oiler):
Refer to TOOL SPECIFICATIONS for setting the correct operating
pressure for the tool.
NOTE:
A filter will help to get the best performance and minimum wear from the tool because dirt
and water in the air supply are major causes of wear in the tool.
Frequent, but not excessive, lubrication is required for the best performance. Oil added thru
the air line connection will lubricate the internal parts.

5. MAINTAIN FOR PERFORMANCE
ΑDO NOT FIRE THE NAILER WHEN IT IS EMPTY
ΒUSE A 3-PIECE AIRSET
Failure to use a 3-piece airset allows the moisture and dirt inside compressor to pass into the tool
directly. This causes rust and wear, and results in a poor operating performance. The hose length
between airset and tool should be no longer than 5 m since a longer length results in a reduction
in air pressure.
ΧUSE RECOMMENDED OIL
The velocite or turbine oil should be used to lubricate the tool. Upon completion of operations,
place 2 or 3 drops of oil into the air plug inlet with the jet oiler. (Recommended Oil : ISO VG32)
∆INSPECT AND MAINTAIN DAILY OR BEFORE OPERATION
Disconnect air supply and empty the magazine when inspecting or maintaining the tool.
(1) Drain air line filter and compressor
(2) Keep lubricator filled in air 3-pieces set
(3) Clean filter element of air 3-pieces set
(4) Tighten all screws
(5) Keep contact arm moving smoothly
6. STORING
ΑWhen not in use for an extended period, apply a thin coat of the lubricant to the steel parts to
avoid rust.
ΒDo not store the tool in a cold weather environment. Keep the tool in a warm area.
ΧWhen not in use, the tool should be stored in a warm and dry place. Keep out of reach of
children.
∆All quality tools will eventually require servicing or replacement of parts because of wear from
the normal use.
