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.
