Instructions
Flow adjustment
If mounting bolts are necessary, order suitable ones selected from the table below. If
mounting bolts from other companies are used, their strength must be 8.8 or up ISO
standards.
Slacken the lock nut and turn the flow adjustment screw clockwise caused the flow rate to decrease
After adjustment, be sure to tighten the lock nut.
