 PERFORMANCE ORDER

1. Turn off clamps (82).
2. Turn off bolts (71).
3. Uncover valvate assembly (72) valvate assembly (74).
4. Remove a sealing plate (73). All 12 balls are located in the case of valves, four 75 of which - plastic, other eight (76) - steel.
5. Turn off covers of the case of valves. Plugs and pistons of adjusting valves (72.2), (72.8) and (74.18) should not be mixed.
6. The valve of switching B2 can be removed and installed when the case of valves is uncovered.
