Adjusting the maximum speed stop screw

7 Idling speed control

Run the pump at 300 rpm and move the control lever till the control rack moves to 5.9-6.0 mm. The control lever
position should be 14+4o.
If the readings are not obtained, replace idling springs.

8 Torque control (torque control travel: 0.6±0.1 mm)
Run the pump at 600 rpm, keep the control lever at maximum speed screw and adjust the tension of torque control
spring by adjusting the threaded bush till the control rack travel is 9.69.8 mm. Check the following readings:

RPM 600 900 1500-1630
C Tr 9.6-9.8 9.2-9.4 9.1

If the readings are not obtained, replace torque control spring sleeve with different collar thickness (if the C. Tr. at
full load is other than 9.1 mm, take only the difference in C.Tr. from 600-1400 грm).
