STEP
37.
Charge actuator accumulator.
CAUTION
Ensure regulator valve is fully backed off to relieve tension in diaphragm. Failure to
comply may result in damage to equipment.
NOTE
Have suitable container ready to catch oil.
a.
Adjust regulator valve (Figure 49, Item 2) on nitrogen tank (Figure 49, Item 3) to 800-900 psi
(5,516-6,206 kPa).
b.
Open shutoff valve (Figure 49, Item 4). Read pressure measuring device (Figure 49, Item 5).
c.
When pressure reaches 800-900 psi (5,516-6,206 kPa), close shutoff valve (Figure 49, Item 4), nitrogen
tank valve (Figure 49, Item 1), and accumulator charge valve (Figure 49, Item 6).
d.
Wait 15 minutes and open accumulator charge valve (Figure 49, Item 6).
e.
Read pressure measuring device (Figure 49, Item 5) to determine if accumulator can retain charge.
