Rated pressure adjustment: The equipment is set as per the rated pressure of 1.0MPa before being
delivered. If the maximum pressure required for the user's air equipment is 1.0 MPa, the user can use it
directly after start-up, without resetting the working pressure of the pressure regulator by yourself; if the
maximum pressure required for some users’ air equipment is less than 1.0 MPa. For example, the
maximum pressure required for the user's air equipment is only 0.8MPa pressure. At this time, the user
needs to adjust the working pressure of the relevant proportional valve (i.e. pressure regulator). The
adjustment procedure is as follows:
Step I, turn the LOAD/UNLOAD switching valve to “- or UNLOAD” position. Start the equipment and
make it operate normally. Then, the LOAD/UNLOAD switching valve to “+ or LOAD” position.
Slowly turn down the air outlet valve of compressor with hand to increase the pressure to 0.8MPa;
Step II, loosen the locknut 2 on the proportional valve (i.e., pressure regulator). Rotate the regulating
screw 1 clockwise until the air is discharged from the air release hole 3 of proportional valve (i.e.,
pressure regulator);
Step III, re-lock the nut 2 on the proportional valve (i.e., pressure regulator).
