Resumen del manual
2. Increase frequency of oil changes if humidity or operating conditions are extreme. Every 160 Hours of Operation: 1. Check drive belt tension; adjust if necessary. (Refer to SERVICE INSTRUCTIONS in this manual.) 2. Inspect air lines and fittings for leaks; correct as necessary. 3. Check the alignment of the motor pulley to the flywheel. If necessary, align to within 1/32 inch on centerline. Each Year of Operation or if a Problem is Suspected: Check condition of air compressor pump intake and exhaust valves. Replace if damaged or worn out. SERVICE INSTRUCTIONS Air Filter - Inspection and Replacement Keep the air filter clean at all times. Do not operate the compressor with the air filter removed. A dirty air filter will not allow the compressor to operate at full capacity. Before you use the compressor, check the air filter to be sure it is clean. If it is dirty, replace it with a new filter. On some models, the filter may be removed by using a pair of needle nosed pliers or a screwdriver. Pull or pry out the old filter. Push in the new air filter. Other models require removal of the belt guard and/ or filter retainer. Oil - Checking and Changing Overfilling with oil will cause premature com pressor failure. Do not overfill. Check oil level in the crankcase daily. Remove the oil fill plug. The oil level should be even with the top of the fill hole and must not be allowed to be lower than 3/8" from the top (6 threads) at any time. It is recommended that the oil be changed after every 100 hours of operation. To drain the oil, remove the oil drain plug and collect the oil in a suitable container. Be sure to replace the plug securely before adding new oil. Use a compressor oil such as Castrol Heavy Duty 30 weight. Crankcase oil capacity is 16 fluid ounces (473.2 ml). Check Valve - Inspection and Replacement Remove and inspect the check valve at least once a year or more often if the compressor is heavily used. Moisture and other contaminants in the hot compressed air will cause an accumulation of a carbon-like residue on the working parts. If the valve has heavy carbon build-up, it should be replaced. Use the following procedure to inspect, clean or replace the check valve. 1. Unplug compressor. Release air pressure from the air tank. 2. Loosen the top and bottom tube nuts and remove the outlet tube. 3. Unscrew the check valve (turn counterclockwise) using socket wrench (7/8"). 4. Check that the valve disc moves freely and that the spring holds the disc in the upper, closed position. The check valve may be cleaned with a solvent. 5. Apply sealant to the check valve threads. Reinstall the check valve (turn clockwise). Do not overtighten. 6. Replace the outlet tube and tighten top and bottom tube nuts. Safety Valve - Inspection and Replacement IF THE SAFETY VALVE DOES NOT WORK PROPERLY, OVER-PRESSURIZATION MAY OCCUR CAUSING AIR TANK RUPTURE OR EXPLOSION. DAILY PULL THE RING ON THE SAFETY VALVE TO MAKE SURE THAT THE SAFETY VALVE OPERATES FREELY. IF THE VALVE IS STUCK OR DOES NOT OPERATE SMOOTHLY, IT MUST BE REPLACED WITH A VALVE HAVING THE SAME PRESSURE RATING. 9 Belt - Replacement SERIOUS INJURY OR DAMAGE MAY OCCUR IF PARTS OF THE BODY OR LOOSE ITEMS GET CAUGHT IN MOVING PARTS. NEVER OPERATE THE OUTFIT WITH THE BELT GUARD REMOVED. THE BELT GUARD SHOULD BE REMOVED ONLY WHEN THE COMPRESSOR IS UNPLUGGED. Belt Guard - Removal and Installation (Refer to Outfit Parts Listing, if required.) 1. Move the "ON/AUTO-OFF" lever to the "OFF" position. Unplug the compressor. Release all air tank pressure. 2. On one-piece belt guards, remove the two beltguard screws on the bottom front of the outfit. 3. On two-peice belt guards, remove the front of the belt guard by disengaging the snaps. Insert a flat bladed screwdriver at each snap location and pry the beltguard apart. Replace Belt 1. Unplug compressor. 2. Remove (one-piece) beltguard, or front of (two-piece) beltguard as described above. NOTE Loosen the wing nut at the hold down plate. The motor can be tilted to allow for easy removal or installation of the belt. 3. Remove belt and replace. NOTE The belt must be centered over the grooves on the flywheel and motor pulley. Adjust Belt Tension Adjust belt tension by tightening the wing nut until it makes contact with the washer, plus one additional turn. Pressure Switch - Replacement PRESSURE LOADS BEYOND DESIGN LIMITS MAY CAUSE TANK RUPTURE OR EXPLOSION. PRESSURE SWITCH OPERATION IS RELATED TO MOTOR HP, TANK RATING AND SAFETY VALVE SETTING. DO NOT ATTEMPT TO ADJUST, REMOVE OR DEFEAT THE PRESSURE SWITCH, OR CHANGE AND MODIFY ANY PRESSURE CONTROL RELATED DEVICE. IF REPLACEMENT IS NECESSARY, THE SAME RATED SWITCH MUST BE USED. CONTACT A DEVILBISS AIR POWER AUTHORIZED SERVICE CENTER FOR REPLACEMENT. Motor Overload Protector - Reset The motor has a manual thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. Turn t...
