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
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 equipmentby 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 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.
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.

5
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.

6
14. DO NOT DRIVE FASTENERS CLOSE TO THE EDGE AND CORNER OF THE WORK
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.
22. DO NOT USE ON SCAFFOLDINGS LADDERS.
The tool shall not be used for specific application for example:
When changing one driving location to another involves the use of
scaffoldings, stairs, ladders, or
Ladder alike constructions, e.g. roof laths,
Closing boxes or crates,
Fitting transportation safety systems e.g. on vehicles and wagons.

NAILER CONNECTION AND OPERATION
NOTE: The information contained in this manual is designed to assist you in the safe operation
of the nailer. Some illustrations in this Manual may show details or attachments that are
different from those on your nailer.
Air Supply, Connections and Operating Pressure
Read section titled SAFETY. Make sure of the following before operation: Air Supply
Power Source (Compressor)
Use only clean, dry, regulated compressed air as a power source for this nailer.
NEVER use oxygen or other bottled gases, as an explosion may occur.
Use suitable air compressors used to supply compressed air to this nailer
Moisture or oil in the air compressor may accelerate wear and corrosion in the
nailer.
Drain daily.
Connections
1. Fittings
Install a female coupler to the hose. The female coupler will connect to the quick release that
fits the tool.
2. Filter-Regulator-Lubricator
NEVER connect nailer to pressure which potentially exceeds 120psi.
Filter-regulator-lubricator units supply an optimum condition for the nailer and extend
the nailer life. These units should always be used.
Filter
The filter removes moisture and dirt mixed in compressed air.
Keep the filter clean by maintaining tool regularly.
Darin daily.
Regulator
The regulator controls the operating pressure for safe operation of the nailer.
Inspect the regulator before operation to be sure it operates properly.

9
Nailer Connection and Operation
Lubricator
The lubricator supplies and oil mist to the nailer.
Inspect the lubricator before operation to be sure the supply of lubricant is adequate.
If an inline lubricator is not used, a few drops of oil will need to be added to the nailer
inlet before each use.
3. Air Hose
Air hose must have a minimum working pressure rating of 180 psi.
Hose has a min. ID of 1/4"(ISO 7-1) and max. length of no more than 17'(5 meter).
The supply hose should contain a fitting that will provide "quick disconnecting" from the
male plug on the tool.
Operating Pressure
Recommended operating pressure range is 70 to 100 psi.
Maximum permissible operating pressure is 120 psi.
Select the operating pressure within this range for the best fastener performance. The
nail length and thickness and the hardness of the wood are factors in determining what
the pressure should be set at.
Do not exceed this recommended operating pressure.
NOTE: Dirt and water in the air supply are major causes of wear in the tool.
An air filter will help to get the best performance and minimum wear from the tool. Frequent,
but not excessive, lubrication is required for the best performance. Oil added through the air
line connection will lubricate the internal parts.
WARNING
NEVER connect nailer to pressure which potentially exceed
120psi.
DO NOT USE THE WRONG FITTING ON NAILER.
The nailer and air hose must have a hose coupler so that all
pressure is removed from the nailer when the coupler is
disconnected. The connector on the tool must not hold pressure
when the air supply is disconnected. If the wrong fitting is used,
the tool can remain charged with air after disconnecting and thus
will be able to drive a nail even after the air line is disconnected,
possibly causing injury.
DANGER
NEVER use oxygen or other bottled gases, as an
explosion may occur.
