OPERATION
PRIMING THE PUMP
NOTE:
The pump is shipped
WITHOUT
oil. Before starting, pour
in oil provided in the pump through the oil nozzle. The
break-in oil should be changed after 8 hours of
operation. To reduce maintenance and repair problems,
use only premium compressor oil. SAE 10W-30 all
weather air compressor oil is recommended for
general use.
1. Check the oil level in the pump through the oil sight glass.
The pump oil level must be between A1 and A2. Do not
overfill or underfill. (See A)
2. Turn the pressure switch to the OFF position (See B)
3. Open the tank drain valve (See C). Turn counterclockwise.
4. Plug in the power cord
5. Turn the pressure switch to the ON position (See D). The
unit will start. Allow the unit to run for half an hour to break
in the internal parts. After half an hour, if the unit does not
operate properly, shut down immediately and contact
GreatNeck Service Center at 1-855-900-2653.
6. After half an hour, turn the pressure switch to the OFF
position.
7. Close the tank drain valve. Turn clockwise.
8. Turn the pressure switch to the ON position. The unit will
start and fill the tank to the cut-out pressure and stop.
NOTE:
The pressure switch will restart the motor automatically
as compressed air is used.
STARTUP
1. Before starting, check the oil sight glass to ensure that oil
level in the pump is at the required level.
2. Turn the pressure switch to the OFF position.
3. Close the tank drain valve.
4. Plug in the power cord.
5. Turn the pressure switch to the ON position.
6. Adjust the pressure regulator to the working pressure of
the tool.
When adjusting from a higher to a lower pressure, turn the
knob counterclockwise past the desired setting, then turn
clockwise to reach the desired pressure. DO NOT exceed
operating pressure of the tool or accessory being used.
SHUTDOWN
1. Turn the pressure switch to the OFF position.
2. Unplug the power cord.
3. Reduce pressure in the tank through the outlet hose. You
can also pull the relief valve ring and keep it open to relieve
