WARNING

Hydraulic oil in system can be under pressures over 3000 psi 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 MLRS

attachment on ground, move control levers through all operating positions several times to relieve live pressure. Relieve pressure

in hydraulic oil tank by loosening filler cap very slowly. Failure to follow these precautions could result in serious personal injury.

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

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 lines and plug holes after

removing lines. Contamination of hydraulic system could result in premature failure.
