240 Volt Single Pump Air Compressors
Check that the electricity supply is turned off.
Check that the compressor’s pressure switch is turned to the OFF position marked “0”.
Connect an air hose to the compressor’s discharge outlet coupling by pulling back the locking collar
on the socket, inserting a compatible Nitto-style male plug (fitted to one end of the air hose) into the
socket, and then releasing the locking collar. Check that the connection is secure by ensuring that the
locking collar is fully engaged and also by trying to pull the air hose away from the coupling.
Plug in the compressor’s electrical supply lead.
Switch on the electricity supply.
Turn the compressor’s pressure switch to the ON / AUTO position marked “I”. The compressor will
now start automatically whenever the air receiver pressure drops to or below the pre-set cut-in
pressure of approximately 650 kPa (94 psi) or 950 kPa (138 psi) depending on the model. It will also
stop automatically whenever the air receiver pressure reaches the pre-set cut-out pressure of
approximately 870 kPa (126 psi) or 1,200 kPa (174 psi), respectively, depending on the model.
To adjust the output air pressure from a compressor fitted with a filter-regulator, lift the black knob
on top of the filter-regulator to unlock it and then turn it to the desired setting by referring to its
pressure gauge. Then push the knob back down to lock it.
When compressor operation is no longer required, always turn the pressure switch to the OFF
position marked “0” before switching off the electricity supply or unplugging the supply lead. Always
use the pressure switch to turn the compressor on and off otherwise the electric motor may be
damaged.

240 Volt Dual Pump Air Compressors
Check that both electricity supplies are turned off.
Check that the compressor’s pressure switches are both turned to the OFF position marked “0”.
Connect an air hose or flexible pipe to the compressor’s discharge outlet valve using a compatible
