(a) Screw
(B) Nut
Bolt c
(d) Speed lever
(e) Actuator shaft
1. Actuator adjustment procedure
(1)Position the speed lever (d) in the idle position.
(2)Set bolt (c) so that the clearance between the speed lever (d)'s pin and the actuator shaft (e) is approximately L1.
(3)Loosen the nut (b) and fully tighten the screw (a).
(4)Set the pump speed at N1 and read the rack position when negative pressure P1 is applied to the actuator.
(5)Gradually loosen screw (a) and fix the nut (b) when the pump speed is N2 and the rack position is R1.
(6)Apply negative pressure several times and confirm that the lever (d) returns to the idle position at negative pressure '0.'
(7)Confirm that rack position is R2 when negative pressure is P2.
----------
L1=2mm N1=500r/min P1=66.7kPa(500mmHg) N2=500r/min R1=9.1mm P2=66.7kPa(500mmHg) R2=9.1mm
