1. SAFETY INSTRUCTIONS
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.
The employer is responsible to enforce the use of eye protection equipment by the tool operator
and all other personnel in the work area.
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 70 to 100 p.s.i. (5 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 unattended, moving to a different work area, adjusting,
disassembling, or repairing the tool, and when clearing a jammed fastener.
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.

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 YOURSELF AND OTHER PERSONNEL
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 and unloading 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 ON THE WORK SURFACE 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 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.

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 IF ANY PORTION OF THE TOOL CONTROLS (e.g., TRIGGER, CONTACT
ARM) IS INOPERABLE, DISCONNECTED, ALTERED OR NOT WOKING PROPERLY
20. NEVER ACTUATE THE TOOL INTO FREE SPACE
This will avoid any hazard caused by free flying fasteners and excessive strain of the tool.
21. ALWAYS ASSUME THAT THE TOOL CONTAINS FASTENERS
22. RESPECT THE TOOL AS A WORKING IMPLEMENT
23. NO HORSEPLAY
24. NEVER LOAD THE TOOL WITH FASTENERS WHEN ANY ONE OF THE OPERATING CONTROLS
(e.g., TRIGGER, CONTACT ARM) IS ACTIVATED
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 the handle, never carry the tool by the air hose.
• The tool must be used only for the purpose it was designed.
• Never remove, tamper with the operating controls (e.g., TRIGGER, CONTACT ARM)
