Dismantling

 PERFORMANCE ORDER

1. Unscrew clamps 82.
2. Unscrew bolts 71.
3. Uncover cases of valves 72 the case of valves 74.
4. Remove a sealing plate 73. All 12 balls are located in the case of the valves, four 75 of which - plastic, other 8 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. The valve of switching В2 can be removed and established, when the cover of the case of valves is removed.


Assembly

 PERFORMANCE ORDER

Assembly is carried out as it should be, the return to dismantling. Insert directing finger 59 into the case of valves (shooter).
