A dirty air filter will not allow the compressor pump to operate at full capacity. Before you use the compressor pump, check the air filter to be sure it is clean and in place.
If it is dirty, replace it with a new filter. On some models,the filter may be removed by using a pair of needle nose pliers or a screwdriver. Pull or pry out the old filter and carefully clean the filter area. Push in the new air filter.
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" to prevent excessive belt wear.
The air compressor flywheel and motor pulley must be
1.Unplug air compressor from power source.
2.Remove belt guard
3.Place a straightedge against the outside of the flywheel and the motor drive pulley.
4.Measure the distance between the edge of the belt and the straightedge at points A1 and A2 in figure. The difference between measurements should be no more than 1/16".
5.If the difference is greater or less than 1/16" loosen the set screw holding the motor drive pulley to the shaft and adjust the pulley’s position on the shaft until the A1 and A2 measurements are within 1/16" of each other.
6.Tighten the motor drive pulley set screw to
7.Visually inspect the motor drive pulley to verify that it is perpendicular to the drive motor shaft. Points B1 and B2 of Figure should appear to be equal. If they are not, loosen the setscrew of the motor drive pulley and equalize B1 and B2, using care not to disturb the belt alignment performed in step 2.
8.Retighten the motor drive pulley setscrew to
9.Reinstall belt guard.
Air Compressor Pump Intake and Exhaust Valves
Once a year have a Trained Service Technician check the air compressor pump intake and exhaust valves.
Inspect Air Lines and Fittings for Leaks
1.Turn the air compressor on to inspect for air leaks.
2.Apply a soap solution to all air line fittings and connections/piping.
3.Correct any leaks found.
IMPORTANT: Even minor leaks can cause the air compressor to overwork, resulting in premature breakdown or inadequate performance.
