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 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 high pressure gas, combustible gases (e.g. Oxygen, acetylene, etc.)
since there is the danger of an explosion. For this reason, do notuse anything
other than compressed air.
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 THE 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 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
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 on the tool.
21. ALWAYS ASSUME THAT THE TOOL CONTAINS FASTENERS.
22. DO NOT USE ON SCAFFOLDING 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.
•NEVER use oxygen or other bottled gases, as an explosion may occur.
•Use suitable air compressors used to supply compressed air to this tool.
•Moisture or oil in the air compressor may accelerate wear and corrosion in the
tools.
•Drain daily.
Connections
1. Fittings
Install a female coupling to the hose. The female coupling will connect to the quick release
that fits the tool.
2. Filter-Regulator-Lubricator
•NEVER connect the tool to pressure which potentially exceeds 120psi.
•Filter-regulator-lubricator units supply an optimum condition for the tool and extend
the tool life. These units should always be used.
Filter
•The filter removes moisture and dirt from compressed air.
•Keep the filter clean by maintaining regularly.
•Drain daily.
Regulator
•The regulator controls the operating pressure for safe operation of the tool.
•Inspect the regulator before operation to be sure it operates properly.

Tool Connection and Operation
Lubricator
•The lubricator supplies an oil mist to the tool.
•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 pneumatic oil will need to be added
to the tool 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)
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. Pneumatic 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 coupling so that all
pressure is removed from the nailer when the coupling 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.
