1. Unscrew the throttle valve (Figure 11/11) from the head with a wrench by turning it counter-
clockwise.
2. Screw the new throttle valve (Figure 11/11) into the head and tighten it (tightening torque:
450 Ncm).
Note
The throttle valve (Figure 11/11) has a defined factory setting.
Therefore, no changes may be made to the throttle valve before it is
mounted on the head.
Should deviations or discrepancies nevertheless occur, the following must
be observed according to Figure 14:
1. Threaded part (Y) and adjusting screw (X) must be flush for assem-
bly.
2. Valve diaphragm (Z) must be completely screwed in and must not
be tightened.
3. Set the delivery rate according to chapter 14.2.
