 PERFORMANCE ORDER

1. Unscrew clamps (82).
2. Unscrew bolts (71).
3. Uncover klapanny assembly (72) klapanny assembly (74).
4. Remove a sealing plate (73). All 12 balls are located in the case of the valves, four 75 of which - plastic, other eight (76) - steel.
5. Unscrew 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 В2 can be removed and established, when the cover of the case of valves is removed.
