GENERAL SAFETY INSTRUCTIONS
 Read and understand all these instructions before attempting to operate your product. Save
these instructions for future reference.
 Before using your air stapler: Place a maximum of one drop of air tool oil in the air inlet daily
before use. Over-oiling will cause air leakage. Check and drain any moisture which may be in
the air tank of your compressor. Failure to drain this moisture may damage the interior of the
stapler and cause unit to jam and/or cause air leakage. Before use, please read the instruction
manual completely for safety and maintenance questions.
 Never allow the use of oxygen or combustible gas as a power source for the tool. Use
filtered, lubricated, and regulated compressed air only.
 Never use gasoline or other flammable liquids to clean the tool. Vapors in the tool may ignite
by a spark and cause the tool to explode.
 Do not exceed maximum permissible operating pressure of the tool (120 PSI).
 Disconnect the tool from air supply before clearing jams, servicing, adjusting, and during
non-operation.
 Do not place your hand or any part of your body in the fastener discharge area of the tool
when connecting or disconnecting the air supply.
 Do not keep the trigger pulled on a safety yoke mechanism when carrying or holding the tool.

AIR SUPPLY AND CONNECTIONS
 The compressed air power source shall be pressure-regulated. The regulated
pressure must not exceed the maximum air pressure marked on the tool. If a
regulator fails, the pressure delivered to the tool must not exceed 1.5 times the
maximum air pressure, or 180 PSI, whichever is greater.
 Pressure regulators shall be used to limit the air pressure supplied to the tool.
Regulators shall be set at an operating pressure which is lower than or equal to the
tool manufacturer’s specified maximum air pressure.
 Air supply hoses shall have a minimum working pressure rating equal to or greater
than the pressure from the power source if a regulator fails, or 120 PSI, whichever is
greater.
 Tools shall be fitted with a fitting or hose coupling on or near the tool in such a manner
that all compressed air in the tool is discharged at the time the fitting or hose coupling
is disconnected.
 Many air tool users find it convenient to use an
oilier to help provide oil circulation throughout
the tool and to increase the efficiency and useful
life of the tool. Check oil level in the oilier daily.
 Many air tool users find it convenient to use a
filter to remove liquids and impurities which can
rust or wear internal parts of the tool. A filter can
also increase the efficiency and usefulness
of the tool. The filter must be checked on a daily
basis, and if necessary, drained.
 For better performance, install a 3/8” quick
connector (1/4” NPT threads) with an inside
diameter of .315” on your tool and a 3/8” quick
coupler on the air hose.
The following illustration shows the correct mode of connection to the air supply
system which will increase the efficiency and useful life of the tool.

FEATURES AND OPERATION
FEATURES
 Large capacity magazine with a quick action latch makes loading easy.
 The safety lock on the nosepiece must be placed firmly onto the work surface to prevent
accidental firings.
 A tapered nosepiece allows greater visibility for precise fastener placement.
 A safety switch (Fig. A) that prevents accidental operation of the tool. The switch is located
inside the trigger. To lock the trigger, pull the cover of trigger towards the rear of the unit. To
unlock tool, release (push forward) the cover of trigger. A key lock or tie strip can be place
into the slot for safety storage of unit.
FASTENER DEPTH ADJUSTMENT
The contact trip (Fig. B) may be adjusted up or down to vary the depth of the fastener in the
workpiece. To adjust, rotate the depth adjustment until the desired setting is achieved.
The tool is designed to operate between 70-120 PSI. Lower pressure (below 70 PSI) will
reduce performance of the tool while higher air pressure (over 120 PSI) raises the performance
of the tool beyond its rated capacity and could cause serious damage to the tool and the user.
Most applications will only require the minimum air pressure. However, larger fasteners and
harder woods may require air pressure in the upper range.
TESTING THE CYCLE OF THE TOOL
NOTE: THE AIR SUPPLY SHOULD BE CLEAN AND DRY. FOR BEST RESULTS, DRAIN
THE MOISTURE FROM YOUR COMPRESSOR DAILY. CHECK AND REPLACE ANY
DAMAGED OR WORN COMPONENTS ON THE TOOL. THE SAFETY WARNING LABELS
ON THE TOOL MUST ALSO BE REPLACED IF THEY ARE NOT LEGIBLE. IN CASE THE
AIR TOOL IS UNABLE TO DRIVE THE STAPLE INTO THE WORKPIECE COMPLETELY,
PLEASE ADJUST THE PRESSURE OF THE AIR COMPRESSOR TO AN APPPROPRIATE
PRESSURE.
 Depress the contact safety trip mechanism
against the workpiece without pulling the trigger.
The tool must not cycle. Never use the tool if a
cycle occurs.
 Hold the tool clear of the workpiece. The contact
safety trip mechanism should return to its original
down position. Pull the trigger. The tool must not
cycle. Do not use the tool if a cycle occurs.
 Then depress the contact safety mechanism
against the workpiece and pull the trigger, the tool
must then cycle.
