handle (B) clockwise,
closing drain valve.
NOTE
After equilibrator accumulator has
been balanced and adjusted pressure
gage (A) should hold above 1500 psi. If
pressure gage (A) drops below 1500
psi, add hydraulic fluid to hydraulic
reservoir (pages 3-262). Notify organi-
zational maintenance you had to add
