Operation; Hose Connections - Northern Industrial Tools 123010 Owner's Manual

· The compressor will cut off on overload and/or excess temperature rise. Turn off the
switch and start it again when the compressor reaches right temperature.
· Choose the suitable pressure switch according to the different usage. When the
setup pressure is lower than the standard pressure, the machine will shut down
automatically, and it will reduce the life of the machine.

OPERATION

· This compressor is fitted with a 1/4" NPT screw thread connection for high-pressure air
hose as a standard feature.
· Connect the appropriate pressure hose.
· Connect the right tools.
· Plug into the main power supply.
· The manometer shows the working pressure. You can use the pressure adjustment to set a
suitable working pressure.
· Ensure that the working area is well ventilated.
THE DIFFERENCE BETWEEN MAXIMUM AND WORKING PRESSURE
A compressor's maximum pressure is the highest pressure it can build up. When a
connected tool (such as airbrush, spray gun) is opened, it is precisely with this pressure that
compressed air initially shoots out through the tool nozzle. In contrast, the working pressure
is the constant pressure the compressor can maintain during airbrushing. The level of this
working pressure depends, on one hand, on the compressor's power (combination of CFM
and maximum pressure) and, on the other hand, the nozzle diameter of the tool to which it is
connected; the larger the nozzle diameter, the greater the amount of air which can escape
and the lower the compressor's working pressure.

HOSE CONNECTIONS

The connections between compressor and hose connector are not always airtight. 100% air
tightness is, however, only absolutely essential in the case of automatic models. It is highly
recommended to use Teflon tape to prevent leakage.
