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.

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.

Most air supply equipment will produce pressures NOTE: Air compressors used

that exceed the SP50’s maximum operating pressure, to supply compressed air to

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.

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.



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.

TROUBLE SHOOTING

Shuttle Punches Through Board:

Pressure too high; staple leg too short.

Staple Leg Buckles And Flattens Against Work Surface:

Staple Leg too long, shuttle not down against work due to worn shuttle piston o-ring.

Driver Punches Through Board:

Worn driver piston bumper.

Staple Ejects From Nose Before Shuttle Contacts Work Surface:

Worn upper driver piston o-ring; excessive air pressure.

Staple Ejects From Rear Opening In Shuttle:

Worn driver piston o-ring.

Air Leakage Through Exhaust Port:

Worn upper driver piston o-ring; worn upper shuttle piston o-ring; worn valve stem seat.

Air Leakage Through Nose Piece:

Worn lower driver piston o-ring; worn shuttle piston o-ring.

Staples Tumbling In Staple Channel:

Feed springs overstressed; feed springs broken; pusher binding on magazine core; dirt

inside magazine; excessive air pressure.

CLEANING JAMS:

Do not attempt to clear jammed staples by firing the tool to clear jam:

1. Disconnect Air supply.

2. Pull back top guide assembly and staples.

3. Pull down shuttle.

4. Remove jammed staple either from opening at the rear of shuttle or form drive

track behind the magazine assembly.

To clear jam caused by tumbled staple or if jam can not be cleared as outlined

above:

1. Be sure air supply is disconnected and top guide is pulled back.

2. Remove staples.

3. Snap magazine spring off magazine back.

4. Lift rear of magazine up and pull magazine back.

5. Remove jammed staple.

6. Slide magazine forward, aligning locating pins with holes in guide.

7. Push rear of magazine; do so with pin in magazine, block engages hole in

frame.

8. Wedge magazine spring back onto magazine block.

*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.
