Examination
1 - vacuum modulating pressure regulator; 2 - modulating pressure adjustment screw; 3 - vacuum control socket; 4 - overload switch; 5 - modulating pressure control socket; 6 - pressure control socket in the centrifugal regulator; 7 - working pressure control socket; 8 - control pressure rod
1. Unscrew plug 5 and connect the oil pressure gauge.
2. Disconnect the hose from the vacuum regulator.
3. Place the selector lever in position "D" and read the pressure gauge at a speed of 50 km/h.
4. In case of deviation from the norm (see Design and technical characteristics) adjust the modulating pressure.

Adjustment
1. Remove the cap from the vacuum regulator.
2. Remove the stopper from the grooves.
3. Turn the adjusting screw with the stopper to set the normal value, and one turn of the adjusting screw changes the pressure by approximately 0.4 kg/cm².
4. After adjustment, insert the stopper into the grooves and put the cap on the vacuum regulator.
5. Check the modulating pressure value and, if necessary, bring it back to normal.
6. Connect the hose to the vacuum regulator.
