OPERATION UNDER USUAL CONDITIONS - CONTINUED
RELIEVING HYDRAULIC SYSTEM PRESSURE
WARN I N G
· DO NOT disconnect or remove any hydraulic system line or fitting unless engine is shut down and hydraulic
system pressure has been relieved. Tighten all connections before applying pressure. Escaping hydraulic fluid
under pressure can penetrate the skin, causing injury or death to personnel.
· At operating temperature, hydraulic oil is hot. Allow hydraulic oil to cool before disconnecting any hydraulic
lines. Failure to follow this warning may result in injury to personnel.
· The accumulator is filled with dry nitrogen. DO NOT loosen or remove the valve or cap from the top of the
accumulator. Failure to follow this warning may result in injury to personnel.
· Never leave operator compartment without engaging parking brake. Failure to follow this warning may result
in injury or death to personnel.
Hydraulic oil can remain under pressure in hydraulic system even after engine has been shut down and hydraulic
pump has stopped.
It is important to relieve this pressure before disconnecting any hydraulic line or performing hydraulic system ser-
Relieving Hydraulic System Pressure.
Park machine on a level surface.
Lower work tool to the ground.
Engage parking brake.
If locked, press bottom of hydraulic lockout (IMPLEMENT DISABLE) switch to unlock hydraulic controls.
CAU T I ON
Stopping engine immediately after it has been operating under a load can result in overheating and
Shut down engine.
Depress brake pedals repeatedly. This will relieve pressure in brake hydraulic system.
Turn engine start switch to ON position without starting engine.
Move loader controls through all positions to relieve pressure in implement hydraulic system.
Turn steering wheel several times in both directions to relieve pressure in steering hydraulic system.
Turn engine start switch to OFF position.
