EXPLODED VIEW & EXPLANATION OF AIR COMPRESSOR FEATURES

AIR TANK DRAIN VALVE: The drain valve is used to remove moisture from the air tank(s) after the air compressor 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 counterclockwise.

OIL SIGHT GLASS: The Oil Sight Glass displays the oil level in the pump. The oil level should be at the center of the Oil Sight Glass. If low, add SAE 30W non-detergent oil.

OIL FILL PORT/VENT: Pour oil into the Oil Fill Port/Vent when required.

Technical line drawing of a mechanical clamp or bracket assembly (no text or symbols)

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 element 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 check valve and/or the pilot valve and into the air tank.

MOTOR/PRESSURE SWITCH: This switch is used to start or stop the air compressor. Moving the switch to the "Auto" (On) position will provide automatic power to the pressure switch which will allow the motor to start when the air tank pressure is below the factory set "cut-in" pressure. When in the Start/Stop Option, the pressure switch stops the motor when the air tank pressure reaches the factory set "cut-out" pressure. For safety purposes, this switch also has a pressure release valve located on the side of the switch designed to automatically release compressed air from the

air compressor pump head and its discharge line when the air compressor reaches "cut-out" pressure or is shut off. This allows the motor to restart freely. Moving the switch to the "Off" position will remove power from the pressure switch and stop the air compressor.

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 pressure should escape. When the ring is released, it will reset.

AIR TANK PRESSURE GAUGE: The air tank pressure gauge indicates the reserve air pressure in the air tank.

AFTER COOLER: (M Series Only) Removes up to 65% of the moisture from discharged compressor air, it also lowers the gas temperature within 20 degrees of ambient.

LOW OIL SHUT DOWN: (M Series Only) the low oil sensor shuts the unit down when the oil levels fall below an adequate level.

Technical line drawing of a mechanical assembly with no visible text or symbols

VIBRATION ISOLATOR PADS: Isolators protect the unit from vibration during use. They also make installation on unlevel surfaces easier.

PNEUMATIC DRAIN: (M Series Only) Drains liquid from tank automatically as the water level rises in the tank.
