a. Removal.

WARNING

Hydraulic oil in system can be under pressures over 3000 psi with engine OFF. ALWAYS relieve

pressure in hydraulic hoses before attempting to remove any component in hydraulic system. With

engine OFF, starter switch in RUN position, and attachment on ground, move control levers

through all operating positions several times to relieve hydraulic pressure. Relieve pressure in

hydraulic oil tank by loosening filler cap very slowly. Failure to follow these precautions could

result in serious injury or death to personnel.

At operating temperatures, hydraulic oil is hot and under pressure. Hot oil can cause injury to

personnel. Allow hydraulic oil to cool before disconnecting any hydraulic hoses.

CAUTION

Wipe area clean around all hydraulic connections to be opened during removal and disassembly. Cap

oil hoses and plug holes. Contamination of hydraulic system could result in equipment failure.

NOTE

If more than one hydraulic hose is to be removed, tag and mark hoses to ensure proper installation.

Use suitable container to catch any hydraulic oil that may drain from system.
