TM 9-2320-364-34-1

High pressure hydraulics [oil under 3675 psi (25,339 kPa) pressure] operate this equipment. Refer to

vehicle operator and maintenance manuals for hydraulic oil pressure. Never disconnect any hydraulic

line or fitting without first dropping pressure to zero. Failure to comply may result in injury to

personnel.

Fuel and oil are slippery and can cause falls. To avoid injury, wipe up spilled fuel or oil with rags.

PRESSURE TEST

(1) Refer to Para 17-5 and check main

hydraulic pump output pressure.

(a) If 3,675 +75, - 50 psi (25,339

+517, - 345 kPa) are not present

on flowmeter pressure gage when

flow drops to 0 gpm ( 0 lpm),

adjust or replace hydraulic

pump control (Para 17-5).

(b) If 3,675 +75, - 50 psi (25,339

+517, - 345 kPa) are present,

hydraulic pump control is OK.

(2) Check main hydraulic reservoir oil

level and add oil as necessary

(TM-9-2320-364-20).
