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

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

REMOVAL

WARNING

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.
