PC2017 FEATURES REVIEW
AIR INTAKE FILTER: This filter is designed to clean air coming into the pump. To ensure the pump continually receives a clean, cool, dry air supply this filter must always be clean and ventilation opening free from obstructions. Replace filter when necessary.
AIR COMPRESSOR PUMP: To compress air, the pistons move up and down in the cylinders. On the downstroke, air is drawn in through the air intake valves while the exhaust valves remain closed. On the upstroke, air is compressed, the intake valves close and compressed air is forced out through the exhaust valves, into the discharge line, through the pilot valve and into the air tank.
PILOT VALVE: When the toggle is in the upright position, all air from the air compressor is vented 
through the discharge muffler. This gives an easy start feature.
For normal operation, the toggle is in the 90° position.
SAFETY RELIEF VALVE: This valve is designed to prevent system failures by relieving pressure from the system when the compressed air reaches a predetermined level. The valve is preset by the manufacturer and must not be modified in any way. To verify the valve is working properly, pull on the ring. Air pres- sure should escape. When the ring is released, it will reseat.
AIR TANK DRAIN VALVE: The drain valve is used to remove moisture from the air tank(s) after the air com- pressor is shut off. NEVER attempt to open the drain valve when more than 10 PSI of air pressure is in the air tank! To open the drain valve, turn the knob counter- clockwise.
AIR TANK PRESSURE GAUGE: The air tank pressure gauge indicates the reserve air pressure in the air tank (s).
PRESSURE REGULATOR: The air pressure coming from the air tank is controlled by the regulator knob. Turn the pres- sure regulation knob clockwise to increase discharge pres- sure, and counterclockwise to decrease discharge pres- sure.
O U T L E T P R E S S U R E GAUGE: The outlet pressure gauge indicates the air pres- sure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less or equal to the air tank pressure.
OIL SIGHT GLASS: The oil sight glass will register the amount of oil in the pump. Ensure the oil level in the air compressor pump is adequate. If low, add
