AiR FILTER - iNSPECTiON AND REPLACEMENT _Hot Risksuorffabcuersn.. Compressor heads are exposed when filter cover is removed. Allow compressor to cool prior to servicing. _Keep clean tahtealal itrimfiletesr. Do not operate the air compressor with the air filter removed. A dirty air filter will not allow the compressor to operate at full capacity. Keep the air filter clean at all times. 1. Remove air filter. 2. Remove the air filter cover. 3. Remove the air filter from filter cover. 6. See the "Adjust Belt Tension" before tightening motor mounting screws. ADJUSTING BELT TENSION 1. Slide motor into original position, line the motor up with the mark made earlier on saddle. 2. Tighten two outside motor mounting screws enough to hold the motor in place for checking pulley and flywheel alignment. 3. The belt should deflect 3/16" (4.8 mm) at midway between the pulley and the flywheel when a 5-10 pound weight is applied at the midway point. IMPORTANT: Do not operate the compressor with the air filter removed. 4. Place new air filter into filter cover. Refer to the Repair Parts for the correct part number. 5. Replace air filter cover and reassemble air filter to pump. BELT = REPLACEMENT (Refer to the Parts List for replacement belt part number.) 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 air compressor power is disconnected. 3. When proper belt tension is achieved, tighten all four motor mounting screws. See Parts list for torque specifications. NOTE: Once the engine pulley has been moved from its factory set location, the grooves of the flywheel and pulley must be aligned to within 1/16" (1.6 ram) to prevent excessive belt wear. Verify the alignment by performing the following Pulley and Flywheel 1. Turn air compressor off, lock out - Alignment. the power supply, and relieve all air pressure from the air tank. 2. Remove the belt guard. 3. Mark pump position on saddle. 4. Loosen the motor mounting screws and slide the motor toward the air compressor. 5. Remove the belt and replace with a new one. MOTOR PULLEY/FLYWHEEL ALIGNMENT NOTE: Once the motor pulley has been moved from its factory set location, the grooves of the flywheel and pulley must be aligned to within 1/16" (1.6 mm) to prevent excessive belt wear. The air compressor flywheel and motor Risk of moving pulley must be in-line (in the same "__" parts. Use caution plane) within 1/16" (1.6 mm) to assure when roiling belt onto flywheel, belt retention within flywheel belt fingers can get caught between the grooves. To check alignment, perform belt and flywheel. the following steps: 1000002023 18 ENG
