INTRODUCTION
The SP50 is a precision-built tool; designed for high speed, high volume stapling. These tools
will deliver efficient, dependable service when used correctly and with care. As with any fine
power tool, for best performance the manufacturer’s instructions must be followed. Please
study this manual before operating the tool and understand the safety warnings and cautions.
The instructions on installation, operation and maintenance should be read carefully, and the
manual kept for reference. NOTE: Additional safety measures may be required because of your
particular application of the tool. Contact your distributor with any questions concerning the
tool and its use.

SAFETY INSTRUCTIONS
WARNING EYE PROTETION which conforms to ANSI 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 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 American
National Standards Institute, ANSI Z87.1-1989 and provide both frontal and side
protection. NOTE: Non-side shielded spectacles and face shields alone do not
provide adequate protection.
WARNING 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 1986 is used.
AIR SUPPLY AND CONNECTIONS
WARNING Do not used oxygen, combustible gases, or bottle gases as a power source for
this tool as tool may explode, possibly causing injury.
WARNING Do not use supply sources which can potentially exceed 200 P.S.I.G as tool may
burst possibly causing injury.
WARNING The connector on the tool must not hold pressure when air supply is
disconnected. If a wrong fitting is used, the tool can remain charge with air after
disconnecting and thus will be able to drive a fastener even after the air line is
disconnected possibly causing injury.

3
WARNING Do not pull trigger or depress contact arm while connected to the air supply as
the tool may cycle, possibly causing injury.
WARNING 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.
LOADING TOOL
WARNING 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
WARNING 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.
WARNING 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
contacted someone or something, causing the tool to cycle.
WARNING 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.
WARNING 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.
WARNING 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.
MAINTAINING THE TOOL
WARNING When working on air tools note the warnings in this manual and use extra care
when evaluating problem tools.

REGULATORS
Most air supply equipment will produce pressures NOTE: Air compressors used
that exceed the SP50’s maximum operating pressure, to supply compressed air to
55 p.s.i (3.9kg/cm²). A pressure regulator is required this plier should comply with
to control the operating pressure. The flow capacity the requirements of the

AIR CONSUMPTION
The SP50 requires 1.75 cubic feet per minute of free air to operate at the rate of 100 staples
per minute, at 55 p.s.i.
Take the actual rate at which the plier will be run to determine the amount of air required.
For instance, if your staple usage averages 50 staples per minute, you need 50% of the
7.75c.f.m. which is required for running at 100 staples per minute.

LOADING THE SP50 SERIES STAPLING PLIER
WARNING EYE PROTECTION which conforms to ANSI 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 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 American
National Standards Institute, ANSI Z87.1-1989 and provide both frontal and side
protection.
NOTE: Non-side shielded spectacles and face shields alone do not provide
adequate protection.
WARNING TO PREVENT ACCIDENTAL INJURIES:
炽Never place a hand or any other part of the body in nail discharge area of tool
while the air supply is connected.
炽Never point the tool at anyone else.
炽Never engage in horseplay.
炽Never pull the trigger unless nose is directly towards the work.
炽Always handle the tool with care.

FILTERS
Dirt and water in the air supply is a major cause of wear in air tools. A filter will help to get
best performance from this plier. The filter must have adequate flow capacity for the specific
installation. The filter has to be kept clean to be effective in cleaning the air. Consult the
filter manufacturer’s instructions on proper maintenance. Clean and empty the filter as
needed. A dirty and clogged filter will also cause a pressure drop, which can reduce the
pliers performance.
