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 2500 psi (17,237 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 oil under pressure can

penetrate the skin, causing serious injury or death.

At operating, temperature hydraulic oil is hot. Allow hydraulic oil to cool before disconnect-

ing any hydraulics. Failure to do so could result in injury.

CAUTION

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

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