4.2.9 Hydraulic circuit
Caution! The hydraulic circuit is under high
pressure. Maximum pressure at work: 200 bar.
Before connecting hoses to the tractor hydraulics,
ensure that tractor and machine circuits are not
under pressure. Before disconnecting a hose,
depressurize the hydraulic circuit.
To avoid making incorrect connections, mark
hydraulic couplers and corresponding hoses with
colors. WARNING! Functions could be reversed (for
example: lift/lower) and cause accidents.
Regularly make visual inspection to check if
hydraulic hoses are damaged or worn. In case of
normal wear, the hydraulic hoses must be replaced
every 5 years. The date of manufacture is indicated
on the hose. Damaged or worn hoses must
immediately be replaced. When replacing the
hydraulic hoses, only use hoses with the
specification recommended by the manufacturer of
the machine.
To locate a leak, use appropriate means. Protect
body and hands from liquid under pressure.
Any liquid under pressure (particularly oil from
hydraulics) can penetrate the skin and cause severe
injury. If injured, see a doctor immediately, there
could be danger of infection.
Before any adjustments, maintenance or repairs are
carried out, lower the machine to the ground,
depressurize the hydraulics, turn off the engine,
remove ignition key and wait until all moving parts
have come to a complete stop.
