If the readings are not obtained, adjust the length of the sliding bolt (1/2 turn of the bolt- approx 2.25 mm C.Tr.) or
change the shim of the curve template (0.15 mm shim thickness = approx 1 mm C.Tr.).
Note: Shorter length of sliding bolt or lesser thickness of shim results in shorter C.Tr. and vice
versa

4 Full load delivery
Assemble the full load stop assembly with torque control. Screw-in the threaded bush of torque control. Run the
pump at 1400 rpm, move the control lever to maxmium position and adjust the hexagonal nuts of the full load
stop till the C.Tr. is 9.1 mm. At this position, the delivery should be 24.224.8 cm³/ 500 strokes. If not, readjust the
hexagonal nuts.

5 Maximum speed control
Control lever at 59 ± 4°, check the following readings:

RPM 1460-1470 1550-1585 1500-1630
C Tr 8.1 4.0 2.0

(If the C.Tr. at full load is other than 9.1 mm, take the difference from actual full load C. Tr.).
Note: With increasing/decreasing speeds. the control rack should move. continuously without jerking.
6 Cutting in speed

Fix control lever in the correct position. Control lever at maximum speed screw, adjust maximum speed screw till
the control rack moves back by 1 mm from the full load position at 1460 1470 rpm.
