Operation and adjustment
Open the drain cock under the tank first and then close it.
The compressor is controlled by a pressure switch when working normally. It stops automatic-
ally as the pressure increases to the maximum and restarts as the pressure decreases to the
minimum. The rated pressure has been adjusted during manufacturing. Do not change the
rated pressure carelessly. As soon as the motor is switched off, the compressed air in the dis-
charge pipe should be released through the outlet valve under the switch. This is necessary
for restarting the motor, otherwise the motor will be damaged. The rated pressure can be ad -
justed by turning the adjusting bolt of the switch
(fig.2).
The outlet pressure of the compressed air can be adjusted by the regulating valve
(fig.2).
Pull
the regulator valve knob up and turn it clockwise to increase the pressure.
When the compressor needs to be stopped when running, you only need to set the pressure
switch knob into the
off
position.

Caution
•
Put the cover off first and put on the air pipe and air filter before running the compressor
(fig.3).
•
Never unscrew any connecting part the tank being under pressure.
•
Never disassemble any electrical part before disconnecting the plug.
•
Never adjust the safety valve carelessly.
•
Never use the compressor when voltage is too low or too high.
•
Never use an electrical cable which is more than 5 m long with less than the cable cross sec-
tion shown in table 1.
•
Never disconnect the plug to stop the compressor, always switch the knob in the
off
position.
•
If the outlet valve does not work as soon as the motor has stopped, search for the cause im-
mediately to avoid any damage to the engine.
•
The lubricating oil must be clean, and the oil level should be kept on the red circle level.
•
Disconnect the plug to cut the power supply off and open the outlet valve afterwards.
