Pump Makes Noise.
Do NOT remove hydraulic tank filler cap or disconnect or remove any hydrau-
lic system line or fitting unless hydraulic system pressure has been relieved.
Hydraulic system pressure can be over 2,500 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 posi-
tions, 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 may cause injury.
Hydraulic oil is slippery and can cause falls. To avoid injury, wipe up spilled oil
