Minimum Flow Rate Loosen lock nut (1) and turn ad- justing screw (2).
Rotating adjusting screw (2) 1/4 a turn clockwise increases the minimum pump flow rate by 6.56 cm3/rev. (0.4 in3/rev). : 17 mm : 19.6 N⋅m (2 kgf⋅m, 14.4 lbf⋅ft) 1) Do not turn adjusting screw (2) more than two turns. 2) Securely tighten lock nut (1) after adjustment. 2. Maximum Flow Rate Loosen lock nut (3) and turn ad- justing screw (4). Rotating adjusting screw (4) 1/4 a turn clockwise decreases the maximum pump flow rate by 8.22 cm3/rev. (0.5 in3/rev). : 13 mm : 9.8 N⋅m (1 kgf⋅m, 7.2 lbf⋅ft) 1) Do not turn adjusting screw (4) more than two turns. 2) Do not increase the maximum flow rate. In other words, do not turn adjusting screw (4) counterclockwise.
3) Securely tighten lock nut (3) after adjustment.
