5. Once the engine has started, move the pressure relief knob to the
engine run position.

Do not attach air tools to open end of the hose until start-up is
completed and the unit checks out OK.

OPERATION AND ADJUSTMENT

1. The compressor is controlled by a pressure switch during normal
operation. It will automatically power down once it reaches maximum
pressure. The rated pressure has been set during the manufactruing
process. Do not change or adjust. As soon as the motor is switched
off, the compressed air in the discharge pipe should be released
through the release valve under the switch. This is the necessary
condition for restart, or the motor will be damaged. The rated pressure
can be adjusted by turning the adjusting bolt of the switch (Fig.3).
2. The output pressure of compressed air can be adjusted by the
regulating valve. Pull up the knob of regulating valve and turn it
clockwise or counterclockwise to increase or decrease the pressure
as shown in figure 3 (below).
3. To turn the compressor off, simply set the switch to the "OFF" position.
