(9)
Stop engine; relieve hydraulic pressure.
CONDITION/INDICATION
Is leakage greater than 1/2 GPM (1.89 LPM)?
DECISION
YES - Reconnect hoses and Replace leaking actuator (TM 5-2320-262-20).
NO - Go to Step (35).
STEP
35.
Perform a pressure test on all No. 1 or No. 4 actuator accumulators.
WARNING
High-pressure nitrogen gas is used in this equipment. Keep hands and face away
from valves and hose ends. Failure to comply may result in severe injury or death
to personnel.
Do not breathe nitrogen gas. Failure to comply may result in severe injury or death
to personnel.
