5. Repeat steps 3 and 4 as needed to remove
any remaining air in the system.
6. With both pistons in the full down position,
activate "KIDNEY DOWN" to apply full system
pressure and close the bypass valve (tighten the
screw).
4. Leave the bypass valve open and activate
"KIDNEY DOWN". Hydraulic pressure keeps the
piston in chamber "C", the hydraulic fluid passes
through the bypass valve and fills cavity "B" push-
ing the piston into cavity "A". See figure 3-13.
b. Cylinder Adjustment
If either of the kidney lift cylinders reaches the end
of the down stroke before the other one, an adjust-
ment is needed. Use the following procedure to
adjust the system.
1. If the right side bottoms out before the left
side, open the bypass valve and activate "KIDNEY
DOWN" to align the cylinders.
2. If the left side bottoms out before the right
side, activate "KIDNEY UP" to raise the cylinders.
When the cylinders are at the full up position, open
the valve and activate "KIDNEY UP" to align the
cylinders. Close the valve before lowering the
cylinders.
3. When the adjustment is complete, make
sure the cylinders are completely down, activate
"KIDNEY DOWN" and tighten the screw to close
the valve.
