TO UNDERSTAND AND FOLLOW THE SAFETY WARNINGS AND INSTRUCTIONS. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN DEATH OR SERIOUS INJURY. KEEP THESE
INSTRUCTIONS WITH THE TOOL FOR FUTURE REFERENCE.
SAFETY INSTRUCTIONS:
EYE PROTECTION which conforms to ANSI/CE specifications and provides protection against
flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and others
in the work area when connecting to air supply, loading, operating or servicing this tool. Eye
protection is required to guard against flying fasteners and debris, which could cause severe eye
injury.
The employer and/or user must ensure that proper eye protection is worn. Eye protection
equipment must conform to the requirements of the ANSI Z87.1 and 89/686/EEC and provide both
frontal and side protection. NOTE: Non-side shielded spectacles and face shields alone do not
provide adequate protection.
CAUTION: Additional Safety Protection will be required in some environments. For example, the
working area may include exposure to noise level which can lead to hearing damage. The
employer and user must ensure that any necessary hearing protection is provided and used by
the operator and others in the work area. Some environments will require the use of head
protection equipment. When required, the employer and user must ensure that head protection
conforming to ANSI Z89.1/ CE is used.
AIR SUPPLY AND CONNECTIONS
Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as tool
may explode possibly causing injury.
Do not use supply sources which can potentially exceed 200 PSI (14 kg/cm2). as tool may burst,
possibly causing injury.
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.
Do not pull trigger or depress contact arm while connected to the air supply as the tool may cycle,
possibly causing injury.
Always disconnect air supply: 1.) Before making adjustments; 2.) When servicing the tool; 3.)
When clearing a jam; 4.) When tool is not in use; 5.) When moving to a different work area, as
accidental actuation may occur, possibly causing injury.
NAIL LOADING
When loading tool: 1.) Never place a hand or any part of body in fastener discharge area of tool;
2.) Never point tool at anyone; 3.) Do not pull the trigger or depress the trip as accidental
actuation may occur, possibly causing injury.
OPERATION
Always handle the tool with care: 1.) Never engage in horseplay; 2.) Never pull the trigger unless
nose is directed toward the work; 3.) Keep others a safe distance from the tool while tool is in
operation as accidental actuation may occur, possibly causing injury.
The operator must not hold the trigger pulled on contact arm tools except during fastening
operation as serious injury could result if the trip accidentally contacts someone or something,
causing the tool to cycle.
Keep hands and body away from the discharge area of the tool. A contact arm tool may bounce
from the recoil of driving a fastener and an unwanted second fastener may be driven, possibly
causing injury.
Check operation of the contact-arm mechanism frequently. Do not use the tool if the arm is not
working correctly as accidental driving of a fastener may result. Do not interfere with the proper
operation of the contact-arm mechanism.
Do not drive fasteners on top of other fasteners or with the tool at an overly steep angle as this may
cause deflection of fasteners which could cause injury.
Do not drive fasteners close to the edge of the work piece as the wood may split, allowing the
fastener to be deflected possibly causing injury.
MAINTAINING THE TOOL
When working on air tools, note the warnings in this manual and use extra care when evaluating
problem tools.

TOOL AIR FITTING
This tool uses a 1/4-18 N.P.T or 1/4-19 P.T. male plug. The inside diameter should be .200” (5 mm) or larger. The
fitting must be capable of discharging tool air pressure when disconnected from the air supply.
TECHNICAL DATA
AIR CONSUMPTION
Tool air consumption: SN50-1.9 cfm (0.9 liter/sec), SN40-1.7 cfm (0.8 liter/sec) of free air to operate at the rate of
100 nails per minute, at 90 PSI (6.0 kg/cm2). Take the actual rate at which the tool will be run to determine the amount
of air required. For instance, if your fastener usage averages 50 nails per minute, you need 50% of the tool air
consumption in running at 100 nails per minute.
NOISE
A-weighted single-event sound power level LWA,1s: SN50-107.4, SN40-105 dBA
A-weighted single-event emission sound pressure level at work station LpA 1s,d: SN50 -106.9, SN40 -104.7 dBA
These values are determined and documented in accordance to EN12549.
VIBRATION
Vibration characteristic value: SN50-3.46, SN40-5.13 m/s
2
These values are determined and documented in accordance to ISO 8662-11.
This value is a tool-related characteristic value and does not represent the influence to the hand-arm-system when
using the tool. An influence to the hand-arm-system when using the tool will, for example, depend on the gripping
force, the contact pressure force, the working direction, the adjustment of mains supply and the workpiece support.
OPERATION
Refer to Operation Instructions and warnings on pages before proceeding to use this tool.
FOUR TYPES OF OPERATION FOR THIS TOOL SERIES.
CONTACT TRIP: IDENTIFIED BY BLACK TRIGGER

8
The common operating procedure on “Contact Trip” tools is for the operator to contact the work to actuate the trip
mechanism while keeping the trigger pulled, thus driving a fastener each time the work is contacted. This will allow
rapid fastener placement on many jobs, such as sheathing, decking and pallet assembly. All pneumatic tools are
subject to recoil when driving fasteners. The tool may bounce, releasing the trip, and if unintentionally allowed to
recontact the work surface with the trigger still actuated (finger still holding trigger pulled) an unwanted second fastener
will be driven.
SEQUENTIAL TRIP: IDENTIFIED BY NICKEL PLATED TRIGGER
The Sequential Trip requires the operator to hold the tool against the work before pulling the trigger. This makes accurate
fastener placement easier, for instance on framing, toe nailing and crating applications. The Sequential Trip allows
exact fastener location without the possibility of driving a second fastener on recoil, as described under “Contact Trip”.
The Sequential Trip Tool has a positive safety advantage because it will not accidentally drive a fastener if the tool is
contacted against the work – or anything else – while the operator is holding the trigger pulled.
TRIGGER OPERATED: IDENTIFIED BY BLACK TRIGGER
The Trigger Operated model is cycle by actuation of the trigger only. The model does not have a Contact Arm
and is intended for use only where a Contact Arm CANNOT be used to satisfy the requirements of the application.
The Trigger Operated tool will cycle each time the trigger is actuated.
REMOTE FIRE: IDENTIFIED BY CONTROL VALVE AIR INLET
(Standard for long magazines models with Remote Valve RCVA1)
AUTOMATIC FIRE: IDENTIFIED BY AUTO-VALVE CAP & BLACK TRIGGER
A tool with automatic firing valve will continuously drive fasteners automatically when the trigger and the trip
mechanism are pressed, said tool will stop firing when the trigger or trip mechanism is released. The rate at
which fasteners are driven in the automatic mode is adjustable. The speed adjustment needle valve is located
on the right side of the tool in the automatic valve cap area. Turning the screw in a clockwise direction increases
speed and in a counterclockwise direction decreases speed.
DIRECTIONAL EXHAUST DEFLECTOR
Loosen screw as shown. Adjust to desired exhaust direction and tighten screw.

AIR SUPPLY AND CONNECTIONS
DO NOT USE OXYGEN, COMBUSTIBLE GASES, OR BOTTLED GASES AS A
POWER SOURCE FOR THIS TOOL AS TOOL MAY EXPLODE, POSSIBLY CAUSING
INJURY.
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: Air hoses should have a minimum of 150 PSI. (10.6 kg/cm2) working pressure
rating or 150 percent of the maximum pressure that could be produced in the air system.
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 this
tool. NEVER USE OXYGEN, COMBUSTIBLE GASES, OR BOTTLED GASES AS A
POWER SOURCE FOR THIS TOOL AS TOOL MAY EXPLODE.
REGULATOR: A pressure regulator with an operating pressure of 0 – 125 PSI (0 -
8.79 kg/cm2) is required to control the operating pressure for safe operation of this tool.
Do not connect this tool to air pressure which can potentially exceed 200 PSI (14 kg/cm2)
as tool may fracture or burst, possibly causing injury.
OPERATING PRESSURE: Do not exceed recommended maximum operating pressure
as tool wear will be greatly increased. The air supply must be capable of maintaining
the operating pressure at the tool. Pressure drops in the air supply can reduce the tool’s
driving power. Refer to “TOOL SPECIFICATIONS” for setting the correct operating
pressure for the tool.
FILTER: Dirt and water in the air supply are major causes of wear in pneumatic tools.
A filter will help to get the best performance and minimum wear from the tool. The filter
must have adequate flow capacity for the specific installation. The filter has to be kept
clean to be effective in providing clean compressed air to the tool. Consult the
manufacturer’s instructions on proper maintenance of your filter. A dirty and/or clogged
filter will cause a pressure drop which will reduce the tool’s performance.
LUBRICATION
Frequent, but not excessive, lubrication is required for best performance. Air-tool
oil added through the air line connection will lubricate the internal parts. Do not use
detergent oil or additives as these lubricants will cause accelerated wear to the seals
and bumpers in the tool, resulting in poor tool performance and frequent tool
maintenance.
If no air line lubricator is used, add oil during use into the air fitting on the tool once or
twice a day. Only a few drops of oil at a time is necessary. Too much oil will only collect
inside the tool and will be noticeable in the exhaust cycle.
COLD WEATHER OPERATION
CAUTION:
NOTE:
For cold weather operation, near and below freezing, the moisture in the air line may
freeze and prevent tool operation. We recommend the use of permanent antifreeze
(ethylene glycol) as a cold weather lubricant.
Do not store tools in a cold-weather environment to prevent frost or ice
formation on the tools operating valves and mechanisms, which could cause
tool failure. Test tool without fasteners prior to operations to ensure no
malfunction on the tool due to ice formation.
Some commercial air line drying liquids are harmful to O-Rings and seals – do
not use these low temperature air dryers without checking compatibility.

10
FASTENER LOADING
EYE PROTECTION which conforms to ANSI/ CE specifications and provides
protection against flying particles both from the FRONT and SIDE should
ALWAYS be worn by the operator and others in the work area when
connecting to air supply, loading, operating or servicing this tool. Eye
protection is required to guard against flying fasteners and debris, which
could cause severe eye injury.
The employer and/or user must ensure that proper eye protection is worn.
Eye protection equipment must conform to the requirements of the ANSI
Z87.1 and 89/686/EEC, and provide both frontal and side protection. NOTE:

and cover to close. Approximately
1/2” (13 mm).
Release Pusher:
Pull and turn the knob in the
clockwise direction to release pusher.

11
“DEPTH OF DRIVE ADJUSTMENT”
The “DEPTH OF DRIVE ADJUSTMENT” feature provides close control of the fastener drive depth;
from flush with the work surface to shallow or deep countersink. First, set the air pressure for
consistent drive in the specific work as described above, then use the “DEPTH OF DRIVE
ADJUSTMENT” to give the desired depth of drive.
TO ALTER “DEPTH OF DRIVE ADJUSTMENT”:
1. With air pressure set, drive a few fasteners into a representative material sample to determine if
adjustment is necessary.
2. If adjustment is required, disconnect air supply.
3. Refer to label on the outside of door for direction to turn adjusting nut. (See illustration)
4. Remove cover mounting nuts, cover and adapter. Observe the orientation of the flats on the
adjusting nut. Rotate the adjusting nut to the left to increase fastener drive depth, or to the right to
decrease it. Reorient the flats to be same as before. Reinstall adapter, cover and mounting nuts.
5. Before reconnecting air supply, check that trip mechanism parts operate freely with no binding or
sticking.
6. Reconnect air supply.

12
OPERATION
There are four available systems on the pneumatic tool:
1. CONTACT TRIP OPERATION:
The CONTACT TRIP MODEL tool contains a contact trip that operates
in conjunction with the trigger to drive a fastener. There are two methods
of operation to drive fasteners with a contact trip tool.
a. SINGLE FASTENER PLACEMENT: To operate the tool in this manner, first
position the contact trip on the work surface, WITHOUT PULLING THE TRIGGER.
Depress the contact trip until the nose touches the work surface and then pull the
trigger to drive a fastener. Do not press the tool against the work with extra force.
Instead, allow the tool to recoil off the work surface to avoid a second unwanted
fastener. Remove your finger from the trigger after each operation
b. RAPID FASTENER OPERATION: To operate the tool in this manner, hold the
tool with the contact trip pointing towards but not touching the work surface. Pull
the trigger and then tap the contact trip against the work surface using a bouncing
motion. Each depression of the contact trip will cause a fastener to be driven.
The operator must not hold the trigger on contact trip tools except during
fastening operation, as serious injury could result if the trip accidentally
contacts someone or something, causing the tool to cycle.
Keep hands and body away from the discharge area of the tool. A contact trip
tool may bounce from the recoil of driving a fastener and an unwanted second
fastener may be driven, possibly causing injury.
2. SEQUENTIAL TRIP OPERATION:
The SEQUENTIAL TRIP MODEL contains a contact trip that operates in conjunction with the trigger to drive a
fastener. To operate a sequential trip tool, first position the contact trip on the work surface WITHOUT PULLING
THE TRIGGER. Depress the contact trip and then pull the trigger to drive a fastener. As long as the contact
trip is contacting the work and is held depressed, the tool will drive a fastener each time the trigger is depressed.
If the contact trip is allowed to leave the work surface, the sequence described above must be repeated to drive
another fastener.
3. TRIGGER OPERATED:
A TRIGGER OPERATED tool requires a single action to drive a fastener. Each time the trigger is pulled the tool
will drive a fastener. The trigger operated model is intended for use only when a contact trip or sequential trip
cannot be used to the requirements of the application.
4. REMOTE FIRE:
The Remote fire model is cycle by actuation of remote valve (RCVA1) for mounted machine.
5. AUTOMATIC FIRE:
A tool with automatic firing valve will continuously drive fasteners automatically when the trigger and the trip
mechanism are pressed, said tool will stop firing when the trigger or trip mechanism is released. The rate at which
fasteners are driven in the automatic mode is adjustable. The speed adjustment needle valve is located on the right
side of the tool in the automatic valve cap area. Turning the screw in a clockwise direction increases speed and in
a counterclockwise direction decreases speed.

SAFE OPERATION
l Use this pneumatic tool only for the purpose for which it was designed like pallet, crating, sheathing,
decking applications
l Never use this tool in a manner that could cause a fastener to be directed toward the user or others in
the work area.
l Do not use the tool as a hammer.
l Always carry the tool by the handle. Never carry the tool by the air hose.
l Do not carry this tool with the trigger depressed when not in use .
l Do not alter or modify this tool from the original design or function.
l Always be aware that misuse and improper handling of this tool can cause injury to yourself and
others.
l Never clamp or tape the trigger or contact trip in an actuated position.
l Never leave a tool unattended with the air hose attached.

MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care
evaluating problem tools. Disconnect air supply and empty the magazine when
inspecting or maintaining the tool.
REPLACEMENT PARTS:
Use only genuine parts from the manufacturer or distributor. Do not use modified parts or parts which will not give
equivalent performance to the original equipment.
Tighten all screws.
Keep contact arm moving smoothly.
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and lubricated. Use O-Ring lubricant on all O-Rings.
Coat each O-Ring with O-Ring lubricant before assembling. Use a small amount of oil on all moving surfaces and
pivots. After reassembly add a few drops of Air Tool Lubricant through the air line fitting before testing.
AIR PRESSURE AND VOLUME:
Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of
undersize fittings and hoses, or from the effects of dirt and water in the system. Restricted air flow will prevent the tool
from receiving an adequate volume of air, even though the pressure reading is high. The results will be slow
operation, misfeeds or reduced driving power. Before evaluating tool problems for these symptoms, trace the air
supply from the tool to the supply source for restrictive connectors, swivel fittings, low points containing water and
anything else that would prevent full volume flow of air to the tool.

DRIVER MAINTENANCE INSTRUCTIONS
Worn driver causing poor driving quality or loss of power:
Wear or a chip on the driver tip will affect the fastener drive, giving symptoms of bent and incompletely driven
fasteners, and damaged fastener heads.
When there is a need, please contact a qualified service technician for this replacement.
TROUBLESHOOTING / REPAIRS
The troubleshooting and / or repairs shall be carried out only by the authorized dealer / distributor or by other
pneumatic tool specialists.
QUICK JAM-RELEASING MAGAZINE
The stapler contains a “Quick Jam-Releasing Magazine” feature. The magazine is spring loaded to reduce
jamming. When a jam does occur, a quick release mechanism at the rear of the magazine allows the magazine
to move back, in order to clear the jam.
ALWAYS DISCONNECT AIR SUPPLY BEFORE CLEARING A JAMMED FASTENER.
If a jam does occur, locate the latch at the rear of magazine (FIG. 1). Pull down on the
latch to open (FIG. 2), and rotate it clockwise 1/4 turn (FIG. 3). Pull back on the latch
(FIG. 4). This will pull the magazine back to clear the jam. After removing the jammed fastener, push on the latch,
rotate it 1/4 turn counterclockwise and push up to close.
SPEED ADJUSTMENT VALVE
FOR MAXIMUM SPEED:
Rotate valve clockwise as far as possible.
TO REDUCE SPEED:
Rotate valve counterclockwise.
