a. Removal.

WARNING

Hydraulic oil in system can be under pressures over 3000 psi (20685 kPa) 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

Remove caps and plugs as hoses are installed. Wipe all sealing surfaces on hydraulic components and

hoses clean and dry. Apply light coating of clean hydraulic oil to all seals as installed.
