Component Identification
1. Lifting Eyes: May also be used as tie down locations.
2. Pressure Gauge : Air filled gauge. Shows pressure in
receiver tank.
3. Ball Valve: On/Off control for pressurized air supply from
receiver tank (not the output pressure). A regulator and/or
quick connect fittings can attach to its ½” NPT outlet. A
regulator should be installed for pressure regulation
purposes.
4. Air Receiver / Storage Tank: 80 gallon ASME certified
tank.
5. Tank Drain Valve: Used to remove moisture from air after
compressor is shut off and air emptied from tank. Drain
moisture daily after each use.

tank exceeds preset pressure max. of 200 PSI. A check
valve is a pressure release port. Pull valve pin to relieve
pressure from receiver tank.

position, compressor shuts off automatically when
tank pressure reaches maximum preset pressure
(approximately 150 PSI). In OFF position, compressor
will not operate. Switch should be in OFF position
when connecting or disconnecting power cord from
electrical outlet. NEVER attempt to adjust this
pressure switch.
8. Discharge Tube: Carries compressed air from pump to
safety/check valve, and then to the storage tank. It
becomes very hot during use and can cause severe burns.
Never touch .
9. Unloader: Vents discharge air to atmosphere in start/stop
operation.
10. Magnetic Oil Drain Plug: Removal allows for drainage of
oil from pump. Attracts metal particles that could damage
pump.
