CORRECTIVE ACTION

1. Engine driven pump fails to raise pressure (Cont).

If the accumulator pressure

does not rise, make certain

that the hand pump relief

valve (3) is closed after

the pressure is released

and repeat the above purg-

ing procedure.

Step 2.

Check for low fluid level.

The fluid level in the

reservoir must be suf-

ficient to completely

cover the screen at the

bottom of the tank after

the accumulator is charged

and the engine-driven pump

is by-passing a full

stream of fluid to the

reservoir.
