5. On the charge valve assembly, locate the T-handle
of the gas chuck (Figure 39). Rotate it
counterclockwise (outward) completely before
attaching the swivel nut to the accumulator gas
valve stem.
6. On the charge valve assembly, close the bleed
valve (Figure 40), and disconnect the hose from the
gas valve stem. This step closes the charge valve
stem to prevent the gas pressure from escaping out
of the hose and ensures that the initial pressure
reading is accurate.
