SAFETY — Continued WARNING

8. STORE STAPLER PROPERLY. When not in use, the Stapler should be stored in a dry place. Keep out of reach of children. Lock the storage area. 9. KEEP WORK AREA CLEAN. Cluttered areas invite injuries. Clear all work areas of un-necessary Staplers, debris, furniture, etc. 10. NEVER USE IN PRESENCE OF FLAMMABLE LIQUIDS OR GASES. The Stapler produces sparks during operation. Never use the Stapler in sites containing lacquer, paint, benzine, thin-ner, gasoline, gases, adhesive agents, and other materials which are combustible or explosive. 11. KEEP VISITORS AWAY. Do not let visitors handle the Stapler. All visitors should be kept away from work area. 12. DRESS PROPERLY. Do not wear loose clothing or jewelry as they can be caught in moving parts. Rubber gloves and nonskid foot-wear are recommended when working indoors. Wear pro-tective hair covering to contain long hair. 13. NEVER USE NON RELIEVING COUPLER ON STAPLER. If a non relieving coupler is used on the Stapler, the Stapler can remain charged with air after disconnecting and thus will be able to drive a Staple even after disconnecting. The Stapler and air hose must have a hose coupling such that all pressure is removed from the Stapler when the coupling joint is disconnected. 14. CHECK PUSH LEVER BEFORE USE. Make sure the push lever operates properly. (The push lever may be called "safety".) Never use the Stapler unless the push lever is operating properly., otherwise the Stapler could drive a fastener unexpectedly,. Do not tamper with or remove the push lever, otherwise the push lever be-comes inoperable. 15. KEEP ALL SCREWS AND COVERS TIGHTLY IN PLACE. Keep all screws and covers tightly mounted. Check their condition periodically. Never use the Stapler if parts are missing or damaged.

16. DO NOT LOAD FASTENERS WITH TRIGGER PULLED OR PUSH LEVER DEPRESSED. When loading fasteners into the Stapler or when connect-ing the air hose, 1) do not pull the trigger; 2) do not depress the push lever; and 3) keep the Stapler pointed downward. 17.KEEP FACE, HANDS AND FEET AWAY FROM DIS-CHARGE AREA DURING USE. Never place your face, hands or feet closer than 8 inches (200 mm) from discharge area. A serious injury can result if the Staples are deflected by the work piece, or are driven away from the point of entry. 18. PLACE STAPLER PROPERLY ON WORKPIECE. Do not drive fasteners on top of other fasteners or with the Stapler at too steep of an angle; the Staples can rico-chet and hurt someone. 19. BE CAREFUL OF DOUBLE FIRE DUE TO RECOIL. If the push lever is unintentionally allowed to recontact the work piece following recoil, an unwanted fastener may be driven. In order to avoid an unlikely double fire, 1) Do not push the Stapler on the work piece with strong

force; 2) Take the Stapler completely away from the work piece

using recoil, and keep the push lever away from the work piece until the next desirable shot; and

3) Pull the trigger and release it QUICKLY when performing intermittent operation.

20. DO NOT DRIVE STAPLES INTO THIN BOARDS OR NEAR CORNERS AND EDGES OF WORK PIECE. The Staples can be driven through or away from the work piece and hit someone. 21. NEVER DRIVE STAPLES FROM BOTH SIDES OF A WALL AT THE SAME TIME. The Staples can be driven into and through the wall and hit a person on the opposite side. 22. CHECK FOR LIVE WIRES. Avoid the risk of severe electrical shock by checking for live electrical wires that may be hidden by walls, floors or ceil-ings. Turn off the breaker switch to ensure there are no live wires. 23. NEVER CARRY STAPLER BY HOSE.

SAFETY — Continued WARNING

24. DO NOT OVERREACH. Keep proper footing and balance at all times. 25. NEVER USE STAPLER WHICH IS DEFECTIVE OR OPER-ATING ABNORMALLY. If the Stapler appears to be operating unusually, making strange noises, or otherwise appears defective, stop using it immediately and arrange for repairs by a PNI authorized service center. 26. DO NOT DISCONNECT AIR HOSE FROM STAPLER WITH FINGER ON TRIGGER. The Stapler can operate when re-connected to an air sup-ply. 27. DISCONNECT AIR HOSE FROM STAPLER WHEN: 1) Doing maintenance and inspection; 2) Loading fasteners; 3) Clearing a jam; 4) It is not in use; 5) Leaving work area; 6) Moving it to another location; 7) Handing it to another person; and 8) Adjusting the knobs. Never attempt to clear a jam or repair the Stapler unless you have disconnected air hose from the Stapler and re-moved all remaining Staples from the Stapler. The Stapler should never be left unattended since people who are not familiar with the Stapler might handle it and injure them-selves. 28. STAY ALERT. Watch what you are doing. Use common sense. Do not operate the Stapler when you are tired. The Stapler should never be used by you if you are under the influence of al-cohol, drugs or medication that makes you drowsy.

29. HANDLE STAPLER CORRECTLY. Operate the Stapler according to the Manual. Never allow the Stapler to be operated by children, individuals unfamil-iar with its operation or unauthorized personnel. 30. NEVER USE STAPLER FOR APPLICATIONS OTHER THAN THOSE SPECIFIED IN THIS MANUAL. 31. HANDLE STAPLER CAREFULLY. Because of high air pressure in the Stapler, cracks in the surface are dangerous. To avoid this, do not drop the Sta-pler or strike the Stapler against hard surfaces; and do not scratch or engrave signs on the Stapler. Handle the Stapler carefully. 32. MAINTAIN STAPLER WITH CARE. Keep the Stapler clean and lubricated for better and safer performance. 33. USE ONLY PARTS, ACCESSORIES OR STAPLES SUPPLIED OR RECOMMENDED BY PNI.

3) Air hose

• Air hoses should have a minimum of 150 psi (10.4 bar 10.6 kgf/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.

4) Hose Coupling

• This tool uses a free-flow connector plug, 1/4 NPT. The inside diameter should be .200" (5mm) or larger. The fitting must be capable of discharging tool air pressure when disconnected from the air supply.

5) Air Consumption

• The model 461A requires 3.1 cfm of free air to operate at the rate of 100 fasteners per minute, at 80 psi. 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 fasteners per minute, you need 50% of the tool’s cfm which is required to operate the tool at 100 fasteners per minute.

6) Operating Pressure

• 70 to 120 psi. Select the operating pressure within this range for best Staple performance. DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.

LUBRICATION Frequent, but not excessive, lubrication is required for best performance. Oil added through the air line connection will lubricate the internal parts. Use Air Tool Lubricant, Mobil Velocite #10, or equivalent. Do not use detergent oil or additives as these lubricants will cause accelerated wear to the seals and piston cushion in the Tool, resulting in poor Tool performance and frequent Tool maintenance. If no airline 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 are necessary. Too much oil will only collect inside the Tool and will be noticeable in the exhaust cycle.

COLD WEATHER CARE 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 WINTER FORMULA Air Tool lubricant (NEW-MATIC Winter Formula or equivalent) or permanent anti-freeze (ethylene glycol) as a cold weather lubricant. CAUTION: Do not store Staplers in a cold weather environment to prevent frost or ice formation on the Staplers operating valves and mechanisms that could cause Stapler failure. NOTE: Some commercial air line drying liquids are harmful to O-rings and seals – do not use these low temperature air dryers without checking compatibility.

• Do not operate the Stapler at high pressure without Staples

CAUTION

WARNING • Never connect Stapler to pressure which

potentially exceeds 200 psi (13.7 bar 14 kgf/cm2). • Never use non relieving coupler on Stapler.

2) Filter-Regulator-Lubricator

• A pressure regulator with an operating pressure of 0-125 psi (0-8.6 bar 0-8.8 kgf/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 as tool may fracture or burst, possibly causing injury.

• Filter-Regulator-Lubricator units supply an optimum condition for the Stapler and extend the Stapler life.

These units should always be used: Filter—The filter removes moisture and dirt mixed in compressed air. Drain daily unless fitted with an automatic drain. Keep the filter clean by regular maintenance. Regulator—The regulator controls the operating pressure for safe operation of the Stapler. Inspect the regulator before operation to be sure it operates properly. Lubricator—The lubricator supplies an oil mist to the Stapler. Inspect the lubricator before operation to be sure the supply of lubricant is adequate. Use PNI pneumatic tool lubricant.

TESTING THE STAPLER

DANGER

• Operators and others in work area MUST wear safety glasses with side shields which conforms to ANSI Z87.1

WARNING • Never use Stapler unless push lever is working

Manufacturer recommends before each use, check all Screws and Nuts to make sure they are tight and have not "jarred loose" from vibration and use. (Shoe, Shoe Base and Pad, Magazine, Magazine Retainer Bracket, Handle, etc.). Manufacturer recommends before each use, check the Driver Blade tip for deformation & breakage to prevent improper driving of Staples and/or to prevent damage to the Stapler and Flooring. Before actually beginning the stapling work, test the Sta-pler by using the check list below. Conduct the tests in the following order. If abnormal operation occurs, stop using the Stapler and contact a PNI authorized service center immediately.

1) Adjust the air pressure to 70psi (4.8 bar, 4.9 kgf/cm2)

Connect the air hose. Do not load any staples in the Stapler. The Stapler must not leak air.

2) Pull the safety trigger.

The Tool must not operate.

3) Remove the finger from the trigger and contact the push lever.

The Tool must not operate.

4) First, pull the safety trigger. Next, contact the push

The Stapler must not operate.

5) First, contact the push lever. Next, pull the trigger.

The Stapler must operate.

ADJUSTING AIR PRESSURE

WARNING DO NOT EXCEED 120 psi. (6.9 bar 8.4 kgf/cm2)

Adjust the air pressure at recommended operating pres-sure 70 – 120 psi (4.9 – 6.9 bar 5 – 8.4 kgf/cm2) according to the hardness of work piece. The correct air pressure is the lowest pressure which will do the job. Using the Stapler at a higher than required air pressure unnecessarily over stresses the Stapler.

STAPLER OPERATION

DANGER

• Operators and others in work area MUST wear safety glasses with side shields which conforms to ANSI Z87.1 specifications.

Read section titled "SAFETY" (pages 4-7)

WARNING

• Keep fingers AWAY from trigger when not driving Staples to avoid accidental operation.

• Never place your face, hands or feet closer than 8 inches (200 mm) from discharge area when using. The Stapler may bounce from the recoil of driving a Staple and an unwanted second Staple may be driven possibly causing injury.

• Check operation of the safety mechanism frequently. Do not use the Stapler if the safety is not working correctly as acci-dental driving of a Staple may result. Do not interfere with the proper operation of the safety mechanism.

• Never clamp or tape the trigger or contact trip in an actuated position.

• Do not drive Staples on top of other Staples or with Stapler at too steep of an angle; Staples can ricochet and hurt some-one.

• Do not drive Staples into thin boards or near corners and edges of work piece. Staples can be driven through or away from work piece and hit someone.

• Do not overdrive Staples. NWFA (National Wood Flooring Association) states that one reason for split tongues is over-driving.

• Never use Stapler which is defective or operating abnor-mally.

• Do not use Stapler as a hammer. • Disconnect air hose from Stapler when: 1) It is not in use; 2) Leaving work area; 3) Moving it to another location; and 4) Handing it to another person. • Wear safety glasses and safety shoes for protection against

foreign objects. • Use only Staples from PNI. • Air supply hoses should have a minimum working pressure

rating of 150 psi or 150 percent of the maximum pressure produced in the power source, whichever is higher.

• Check all hoses before connecting to ensure that they are free from dirt, grit, or particles that could alter the performance of the Stapler.

• An airline Filter and In-Line Air Regulator adjustable to 125 psi max are required.

• NEVER use a defective Stapler. Replace worn or damaged parts immediately. Be sure that the Safety Trigger and operating mechanisms operate correctly and that all screws and seals are securely tightened at all times.

• NEVER point Stapler at yourself or others in work area.

METHODS OF OPERATION The Stapler is equipped with the push lever and does not operate unless the push lever is depressed (upward posi-tion).

SEQUENTIAL TRIP SAFETY OPERATION The model 461A Flooring Stapler operates on a sequential trip system. The sequential trip system requires the opera-tor to hold the Tool against the work before pulling the trigger. This makes accurate fastener placement easier. The sequential trip allows exact fastener location without the possibility of driving a second fastener on recoil. SEQUENTIAL TRIP OPERATION: 1) Press the contact trip against the work surface, without touching the trigger. THE TOOL MUST NOT CYCLE. 2) Hold the Tool off the work surface and pull the trigger. THE TOOL MUST NOT CYCLE. Release the trigger. The trigger must return to the trigger stop on the frame 3) Pull the trigger and press the contact trip against the work surface. THE TOOL MUST NOT CYCLE. 4) With finger off the trigger, press the contact trip against the work surface. Pull the trigger. THE TOOL MUST CYCLE.

WARNING

• Keep your finger off the trigger except during sta-pling operation, because serious injury could result if the push lever accidentally contacts you or others in the work area.

• Keep hands and body away from the discharge area. The Stapler may bounce from recoil of driving a fas-tener and unwanted subsequent fastener may be driven, possibly causing injury.

• Some types of loaded Staples can spark out of the muzzle during a driving operation.

13

FASTENER POSITIONING ADJUSTMENT The fastener position can be adjusted to accommodate 1/4" - 5/8" thicknesses of flooring by way of the adjustment knobs located on the positioning shoe. The shoe adjustment feature provides close control of the fastener positioning to reduce occurrence of split tongues or dimples in the flooring surface. First set the air pressure for consistent drive in the specific work as described on page 11, then use the shoe adjustment knobs to set the desired position of drive. The fastener should be positioned so that it enters the vertical face of the flooring at the point where the tongue meets the vertical face.

TO ADJUST THE TOOL TO THE FLOORING: 1. Loosen both Knobs until the Foot moves freely. 2. Position the foot and to engage the Nose with the Tongue of Flooring and retighten knobs as shown above. 3. Adjust the Front Guide “Elevator Shoe” to the subfloor by turning the adjustment AXLE to raise or lower the “elevator Shoe” so the tool is balanced. Note: periodically check the Knobs to ensure that they are tight during use. **Important: Test the tool on a scrap piece of flooring to ensure proper staple placement and compatibility.

ADJUSTING THE STAPLING DEPTH Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of undersized 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, jamming, 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.

Floor Staple

• Air pressure too low. • Staple crown above tongue. • Increase air pressure.

• Air pressure too high • Staple crown below tongue. • Lower air pressure.

• Correct air pressure • Staple just below surface
