TM 1-1730-231-13&P
WARNING
High hydraulic fluid pressures are developed during cart operation. The
connecting hoses must be free of defects and the hose disconnects
clean to avoid hose rupture or leaks.
2-5.
Preliminary Checks. Prior to operation, the following steps should be taken to ensure the cart will operate
properly and safely:
1.
Open cabinet door and control panel cover prior to beginning checks.
WARNING
Use volatile solvents only in a well ventilated area. Avoid prolonged
contact with skin.
2.
Inspect the connecting hoses and clean hose disconnects using dry cleaning solvent, P-D-680, if necessary.
CAUTION
Never operate the cart if hydraulic fluid level in reservoir is less than
LOW LEVEL sight glass. System damage could result. Replenish as
required.
3.
Observe reservoir sight glasses and add fluid, MIL-H-5606 or MIL-H-83282, until it is to the center of the OPNL
LEVEL sight glass.
4.
Inspect piping and fittings for obvious leaks.
SECTION IV. OPERATING PROCEDURES (AH-64)
