E. Gently tighten the clamping screw on the control arm pivot.
(Figure 2.5)
F. For systems with more than four isolators, use the same basic setup
just described: Two valves control the height of the two end corners
(A & A) while the third valve (B) controls the height of the opposite
end. See Figure 2.8.

2.3.2 Connecting Air Lines
A. Connect air lines to the isolators as shown in Figure 2.8. When
cutting tubing, be sure the ends are round and cut squarely. This is
best done with a single edge razor blade (scissors will deform the
tubing, causing leaks). The connections are detailed in Figures 2.9
and 2.10.
1. Use translucent tubing to connect the air supply to each of the
leveling valves. Use “Tee” connectors as required. Press the free
end of the tubing into the yellow collar of the valve’s “IN” connec-
tor. Be sure the connection is firm by tugging on the tube.
