safety WARNING Risk of Electrical Shock. Never use an electric air compressor outdoors when it is raining or on a wet surface, as it may cause an electric shock. WARNING Risk of Injury. This unit starts automatically. ALWAYS shut off the main power disconnect, and bleed all pressure from the system before servicing the compressor, and when the compressor is not in use.
Page 9
safety WARNING Risk of Eye Injury. Always wear ANSI Z87.1 approved safety goggles when using an air compressor. Never point any nozzle or sprayer toward a person or any part of the body. Equipment can cause serious injury if the spray penetrates the skin.

safety CAUTION Drain the moisture from the tank on a daily basis. A clean, dry tank will help prevent corrosion. Pull the pressure relief valve ring daily to ensure that the valve is functioning properly, and to clear the valve of any possible obstructions.
overview Overview BASIC AIR COMPRESSOR COMPONENTS The basic components of the air compressor are the electric motor, pump, pressure switch and tank (see Fig. 1). The tank may be vertical or horizontal, varying in size and capacity. The electric motor (see A) powers the pump. The electric motor is equipped with an overload protector to help prevent possible motor burnout.

maintenance Maintenance WARNING • This unit starts automatically. ALWAYS shut off the main power disconnect, and bleed all pressure from the system before servicing the compressor, and when the compressor is not in use. Do not use the unit with the shrouds or belt guard removed. Serious injury could occur from contact with moving parts.

ALWAYS shut off the main power disconnect, and bleed all pressure from the system before servicing the compressor, and when the compressor is not in use.
maintenance FIG 8 PULLEY ALIGNMENT To check pulley alignment, remove the belt guard and place a straightedge (see A) against the pump flywheel (see B) (See Fig. 9). Measure and record the distance from the straightedge to the edge of the drive belt at point C. Then measure the distance from the straightedge to the edge of the drive belt again at points D and E.
maintenance CLEANING THE AIR FILTER A dirty air filter will reduce the compressor’s performance and life. To avoid any internal contamination of the pump, the filter should be cleaned frequently, and replaced on a regular basis. Felt filters should be cleaned in warm, soapy water, rinsed, and allowed to air dry before reinstalla- tion.

troubleshooting PROBLEM POSSIBLE CAUSE SOLUTION Overheating Poor ventilation Relocate compressor to an area with cool, dry, well circulated air, at least 12 in. from nearest wall. Dirty cooling surfaces Clean all cooling surfaces thoroughly. Restricted air passages Replace transfer tubes and/or unloader.
glossary of terms CFM: Cubic feet per minute; a unit of measure of air flow. PSI: Pounds per square inch; a unit of measure of air pressure. Kick-in pressure: Factory set low pressure point that starts the com- pressor to repressurize the tank to a higher pressure. Kick-out pressure: Factory set high pressure point that stops the com- pressor from increasing the pressure in the tank above a certain level.
