●T o adjust the pressure, loosen the lock nut and turn the handle slowly
clockwise for higher pressures or anti-clockwise for lower pressures.
After adjustments, do not forget to tighten the lock nut.
● If the internal volume of the vent line is too large, chattering is likely tooccur, so please use the pipes with 4mm inside diameter.
