manual abstract
This air nailer or stapler must be regularly oiled and operated with treated or clean air. It is a precision tool with close internal tolerances designed for repetitious use. Wet and/or dirty air lowers performance and prematurely destroys internal parts. To ensure that the best quality air enters your nailer: 1. Use an in-line system to automatically oil, filter, and dry compressed air. Grizzly offers an in-line regulator/filter/water-separator/lubricator (G2304). Please refer to our catalog for price and ordering information. 2. Keep your air filter clean. Replace periodically. 3. Drain compressor’s air tank(s) frequently; more often in high humidity. This prevents corrosion in the tanks, as well as damage to your nailer or stapler. 4. Keep air hoses as clean as possible internally. Inspect nipples and couplers for any dirt and moisture. Blow out prior to connecting the nailer. -8- G1847 / G1852 / G 1861 / G3811 Air Nailers/Staplers SECTION 4: MAINTENANCE General Maintenance requirements are minimal for these nailers. The two most common problems with any nailer are jamming and damaged drivers. In both cases, the nailer will need to be partially disassembled to make the repairs. The third most common problem is worn out O- rings. Consult the Grizzly service staff for special instructions if needed. Grizzly has replacement parts and special O-ring rebuilding kits available for these tools. WARNING: All inspections and/or any maintenance is to be performed with the air supply disconnected from the tool. Inspect and maintain the following items daily: 1. Check the air nailer for any loose bolts or air leaks. Loose bolts should be retightened. Make sure that all lock washers are in place. Air leaks are an indication that internal seals are worn or nicked and should be replaced. 2. Make sure the safety nose and trigger are functioning properly. Repair as necessary. Do not use the nailer with a broken or modified safety nose. 3. Inspect the automatic lubricating system if applicable and fill as required. Inspect the in- line air and water filters if applicable and change or clean as necessary. 4. Inspect the compressor regulator and/or in- line regulator to ensure that they are set correctly. Adjust accordingly. Cleaning & Oiling CLEANING: Keep the nailer nose as clean as possible. Dirt and debris have a tendency to work their way into the nailer from the nose. Wipe off any dirt that collects on the outside of the nailer before connecting it to the air supply. OILING: Keep the nailer oiled. Use special pneumatic tool oil to keep internal parts well lubricated. This tool oil is available through the Grizzly Catalog (G2820). If your air supply is not pre-lubricated, you must add 2 drops of oil directly into the air nozzle at the rear of the nailer each time the magazine is loaded. NEVER USE any oil that will corrode the rubber O-ring seals such as motor oil, detergent oils, or oils that are used as solvents. Avoid over- oiling. IMPORTANT: When you first pick up an air activated nailer, ALWAYS ASSUME THAT IT IS LOADED. Open the magazine and inspect for any nails or staples before connecting it to the air hose. Do not connect the air supply until you are in position and ready to operate the nailer. DO NOT load or service any pneumatic nailer or stapler without first disconnecting it from its air source. Failure to do so could result in a misfire and possible injury. Ensure that the safety mechanism is working properly each time you use this tool. Under no circumstances should the safety be modified or disabled. Serious injury could occur. G1847 / G1852 / G 1861 / G3811 Air Nailers/Staplers -9 Jamming To repair a jam: 1. Remove any fasteners remaining in the gun. 2. Partially unscrew the cap screws that hold the nosepiece cover in place. Slide the nosepiece cover down and pull it off. Figure 5. (G1861: Remove the safety tip before removing the nosepiece cover.) Jammed Brad Nosepiece Cover Cap Screw Nosepiece 4. Remove any fasteners lodged in the nailer nose. 5. Re-attach the nosepiece cover. Make sure it lines up properly. G1861: Attach the safety tip. 6. Load fasteners and connect the nailer to the air supply. 7. Make sure the safety tip is functioning correctly and that it slides freely. Test fire into a sample piece. If jamming persists, make sure you are using fasteners within the size range of this nailer. If jamming is due to worn or broken parts, repair or replace them before placing the nailer back into service. Aligning Nosepiece The nosepiece may become misaligned if the nailer has been dropped or otherwise mishandled. Misfiring and/or jamming will result if the nosepiece is misaligned – but correcting the problem is simple. To align the nosepiece: 1. Remove the nosepiece cover. 2. Remove fasteners and visually inspect to see if the nail slot in the nosepiece is aligned with the nail slot in the magazine. If it is hard to tell, put a nail in and see if it slides through both slots easily. 3. If the nosepie...
