SAFETY INFORMATION
WARNING:
BEFORE USING THE TOOL, READ CAREFULLY AND UNDERSTAND THE
FOLLOWING SAFETY INSTRUCTIONS.FAILURE TO FOLLOW WARNING
COULD RESULT IN DEATH OR SERIOUS INJURY.
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
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 high pressure gas, combustible gases (e.g. Oxygen, acetylene, etc.) since
there is the danger of an explosion. For this reason, absolutely so not use anything
other than an air compressor to operate the tool.
tool. The employer and/or user must ensure that proper eye protection is worn. 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.
4. OPERATE WITHIN THE PROPER AIR PRESSURE RANGE.
The tool is designed to operate within an air pressure range of 70 psi
to100 psi (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 psi. (8.3 bar).
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 FITTING.
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 line of air 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.
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 YOUR INTEND TO DRIVER 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 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 not loading the fasteners or similar operations.
11. USE SPECIFIED FASTENERS.
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
When changing one driving location to another involves the use of
Ladder alike constructions, e.g. roof laths,
Closing boxes or crates,
Fitting transportation safety systems e.g. on vehicles and wagons.
AND THIN MATERIAL
The work piece is likely to split and the fastener could fly 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 removes all fitting. For this reason, always move the
fasteners away which 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 lose your foot place. Secure
the hose at a point close to the area you are going to driver 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 WORKING
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.
