WARNING
WARNING
WARNING
WARNING
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.
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.
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.
MAINTAINING THE TOOL
WARNING When working on air tools note the warnings in this manual and use extra care when evaluating problem tools.
OPERATING PRESSURE
The operating pressure of the SP50 series plier is
36 to 55 p.s.i (3.9kg/cm²). Tool wear will be greatly
increased if excessive pressure is used.
WARNING
To prevent accidental firing, disconnection air supply:
炽before making
adjustments
炽when servicing the tool
炽when clearing jams
炽when tool is not in use
3
SETTING THE CORRECT PRESSURE
The air equipments will vary, depending on the
material to be stapled and the staple size. Do not
use more air pressure than is required to drive the
staple in the specific job. To determine best setting,
start at low pressure and increase pressure until drive
is satisfactory. Using excess pressure increases tool
wear on the plier and wastes compressed air.
QUICK DISCONNECT FITTINGS
Install a free –flow connector plug on the nailer.
Thread is 1/4” N.P.T.
Install a connector socket on the air hose. For
best performance, fitting should have minimum
inside dia. of .190”(4.8mm).
WARNING
Do not use oxygen or combustible gases as a power sources which can potentially exceed 200
P.S.I as tool may explode.
WARNING
NOTE:The air supply system must be capable of maintaining the required air pressure at the tool when it is operated at its highest cycle speed. Inadequate air supply will result in a loss of power and inconsistent driving after the first cycle when the tool is operated in high speed bursts.
Always attach a free-flow-connector plug to the plier. If a wrong fitting is used, the tool can remain charged with air after disconnecting, and thus will be able to cycle even after the air line is unplugged.
REGULATORS
Most air supply equipment will produce pressures
that exceed the SP50’s maximum operating pressure,
55 p.s.i (3.9kg/cm²). A pressure regulator is required
to control the operating pressure. The flow capacity
must be sufficient for the air usage at the installation.
HOSES
Air supply equipment should have a 85 p.s.i.
(6.0 kg/cm²) working pressure rating (or 150 percent
of the maximum pressure that could be produced in
the air system.)
NOTE: Air compressors used to supply compressed air to this plier should comply with the requirements of the
American National Standards
Institute Standard B19.3-1972,
Safety Standard for
Compressors for Process
Industries.
NOTE: Make sure air lines and fittings are clean before connecting.
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.

WARNING
Disconnect the air supply before making adjustments.
CAUTION: Do not attempt to operate this plier without material between the shuttle and clincher to avoid damaging the driver tip.
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.
5
Frequent but not excessive lubrication is required for best performance. Oil added through the air line connection will lubricate the internal parts. Use Mobil Velocite
#10 oil or an equivalent. Do not use detergent oil or oil additives because the seals and bumpers in the tool may be attacked by the oil.
If an air line lubricator is used, add oil during use by squirting oil into the air fitting on the tool once or twice a day. Only a few drops at a time are required. Too much oil will collect inside the tool and will be noticeable in the exhaust.
For cold weather operation, near and below freezing, the oil and water present in the air line may freeze and prevent operation. We recommend the use of permanent antifreeze (ethylene glycol) as a cold weather lubricant. Note that some commercial air line drying liquids attack o-rings and seals – do not use these low temperature air dryers without checking compatibility.
WARNING
When working on air tools, note the warnings in this manual, and use extra care when evaluating problem tools.
REPLACEMENT PARTS
Replacement parts are commended. Do not use modified parts or parts which will not give equivalent performance to the original equipment. When ordering replacement parts specify by part number.
WARNING
Eye protection should be worn by the person operating or testing the plier, and by others in the work area.
ASSEMBLY PROCEDURES FOR SEALS
When repairing a plier make sure the internal parts are clean and freshly lubricated.
Use Parker O-lube or equivalent on all “O” rings
Coat each “O” rings with O-lube before assembling. Use a small amount of oil on all moving surfaces and pivots. After reassembly, add a few drops of Velocite #10 oil or equivalent, through the air line fitting before testing.
WARNING
Disconnect the air supply supply before making adjustments,servicing the tool, clearing jams, or when tool is not in use.

*Special maintenance instructions:
These are threaded parts that have been assembled with a plastic thread locking compound. They should be replaced in a SPOTNAILS distributor. However, if they must be replaced in the field, they may be separated by heating parts to approximately 450°F when the compound become plastic. Clean parts thoroughly.
Degrease threads with Loctite solvent #75559, apply Locite grade 277, and assemble. Allow 1/2 – 1 hour for sealant to cure at room temperature.
NOTE: The work opening between the shuttle and the clincher can be varied for special applications. The opening should never be increased to more than
31/32 (24.6mm) maximum for Standard Pointed, and Mattress Blade Pliers; and
27/32 (21.4mm) maximum for “C” Blade Pliers. It may be reduced by removing the clincher spacer between the clincher and the frame. If the spacer is removed be sure to check the length of the clincher mounting screws. Be sure they do not hit the magazine when they are replaced. Cut the screws off as needed, or use shorter screws.
Be sure all screws and nuts are checked periodically to keep them tight.
Observe caution against stripping threads when tightening fasteners.
A periodic check should be made of the bumpers. A Worn bumper should be replaced before damage occurs to related parts. To check, disconnect the air supply remove cap and piston. Check bumpers for wear and replace if necessary.
