manual abstract
Do not use any oil that will corrode the rubber O-ring seals such as detergent oils or oils that are used as solvents. With these points in mind, you can operate your nail gun under the best conditions for increased dependability and low overall cost of operation. IMPORTANT: When you first pick up an air activated nail gun you must always assume that it is loaded. Inspect for any nails and load the gun magazine before connecting the gun to the air supply. Do not connect the air supply until you are in position and are ready to operate the gun. A. LOADING FASTENERS To load the gun: 1. Disconnect the air hose if already connected. 2. Pull back on the pusher (Part #428) until it is secured by the latch (Part #430) at the rear of the magazine. 4. Slip the fasteners into the slot in the top of the magazine, one clip at a time. The fasteners are positioned into the slot with points facing down and heads facing up. Ensure that the fasteners are parallel with the gun nose as they enterthe magazine. The magazine will hold three clips. 5. Release the latch (Part #430) so the pusher (Part #428) presses against the fasteners. 6. Connect the air hose to the male quick-connect nipple on the back of the handle. Pull back on the female hose connector sleeve, press the fitting onto the nail gun fitting and release the sleeve. The female fitting will lock onto the male gun fitting. 7. Listen for any air leaks. If no leaks are detected, you are ready to test fire the gun. Figure 2 shows placement of fasteners into the magazine. -5- Prior to operating this nail gun, ensure that all safety procedures are read and understood. This tool is very simple to use which speeds production. However, ease of use and routine production work may invite accidents. Please practice safe work habits at all times and always wear ANSI approved safety equipment. B. TEST FIRING Whenever changing fastener size or composition of material being fastened, the gun should be tested to ensure that the air pressure is set correctly and the gun is working properly. To test fire the gun, wear safety glasses and follow the steps below: 1. Select a sample work piece similar In composition to the type of material you will be fastening. 3. Hold gun perpendicular (90°) to your work and firmly press the safety nose down. 4. Pull trigger. 5. Inspect your results. If nail is set too far into the work piece, reduce the regulated air pressure either at the compressor or at the in-line regulator if equipped. If the nail is not set or protrudes above the work surface, increase the air pressure. However, do not exceed the maximum air pressure recommended for the gun or the hose. C. ROUTINE USE To operate the nail gun during routine use, always wear safety glasses and: 1. Line up gun nose with the area on the work piece you intend to fasten. 2. Hold gun straight and perpendicular to the work surface. 3. Firmly press safety nose against the work piece so that the gun nose rests on the work piece. 4. Pull trigger. This gun can also be continuously fired by holding down on the trigger and firmly pressing the safety nose against the work piece each time you wish to shoot a fastener. However, since this gun will recoil, if only slightly, there is the chance that the gun will misfire if you do not firmly press down each time you wish to shoot a fastener. Do not carry the gun around with the trigger depressed. Caution: Be aware that if the gun nose is positioned too near the edge of the work piece or is not held straight, there is a chance that the fastener will split the work piece or the fastener may be deflected. Also, be aware that compressed air is exhausted out of the top, front of the gun. Do not hold the gun in such a way that exhausted air is blown into your face or someone else’s face. Also, note that exhausted air will cause any nearby dust to become airborne. Use a respirator if necessary. -e- Figure 3 shows holding nail gun for different applications. Sometimes a jam will occur if the gun is misfired or the driver is worn or damaged. If a jam should occur, disconnect the gun from the air supply and follow the directions listed in the maintenance section under special maintenance. VI. MAINTENANCE This nail gun is relatively simple to maintain. However, we have divided this section into: routine maintenance, special maintenance, and problem solving. WARNING: All inspections and/or any maintenance is to be performed with the air supply disconnected from the tool. A. ROUTINE INSPECTION AND MAINTENANCE Inspect and maintain the following items daily: 1. Check the air gun for any loose bolts or air leaks. Loose bolts should be re-tightened. Make sure that all lock washers are in place. Air leaks are an indication that internal seals are worn and should be replaced. 2. Make sure safety nose and trigger are functioning properly and in working order. Repair as necessary. Do not use this gun with a broken or modified safety nose. 3. The a...
