Connecting and Bleeding Pressure Gauge

General




The tester should be connected into the control pressure line at the mixture control unit.

The control pressure now is transmitted from the mixture control unit, through the three-way selector valve, to the control pressure regulators for warm running compensation or throttle valve position respectively.

Thus, all pressure tests can be performed without reconnecting the lines.

For better clarity, connecting points and lever positions are referenced in the instructions given below according to numbers shown in the adjacent illustration.


Connecting and Bleeding Pressure Tester




1. Detach pressure lines for control pressure regulators for warm running compensation and throttle valve position.




2. Insert a gasket in the special tool connector and screw into the control pressure connection of the mixture control unit in place of the banjo bolt.




3. Connect pressure lines of control pressure regulators for warm running compensation and throttle valve position to second connector using original banjo bolt and gaskets.




4. Turn selector valve to position 2. Allow pressure gauge to hang down (hose stretched) and switch the ignition on. Turn lever of three-way selector valve to position 3 about 5 times at 10-seconds intervals.
