a. Removal.

WARNING

Hydraulic oil in system can be under pressures over 3000 psi (20685 kPa) with engine OFF.

ALWAYS relieve pressure in hydraulic lines 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 line pressure. Relieve

pressure in hydraulic oil tank by loosening filler cap very slowly. Failure to follow these

precautions could result in serious injury to personnel.

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

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

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

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