WARNING

Do NOT remove hydraulic tank filler cap or disconnect or remove any hydraulic system line or fitting

unless hydraulic system pressure has been relieved. Hydraulic system pressure can be over 3,000 psi

(20684 kPa), even with engine and pump OFF. To relieve pressure, lower all hydraulic attachments to

the ground and shut down engine. Move control levers through all operating positions, then SLOWLY

loosen hydraulic tank filler cap. After maintenance, tighten all connections before applying pressure.

Escaping hydraulic fluid under pressure can penetrate the skin, causing injury or death.

At operating temperature hydraulic oil is hot. Allow hydraulic oil to cool before disconnecting any

hydraulics. Failure to do so could result in injury.

When working underneath the boom, always support the boom using blocks, jackstands or other rigid

and stable supports. Combined weight of boom and MLRS attachment is approximately 6,300 lb (2858

kg). Failure to adequately support the boom could result in severe injury or death.

CAUTION

Wipe are clean around all hydraulic connections to be opened during removal and disassembly. Cap oil lines

and plug holes after removing lines. Contamination of the hydraulic system could result in premature failure.

NOTE

If more than one hydraulic line is to be removed, identify lines to ensure proper installation. Use container to

catch any hydraulic oil that may drain from system.
