Precautions When Coupling; Hydraulic Circuit - KUHN GMD16 Operator's Manual

4.2.8 Precautions when coupling

Before attaching the machine, make sure that it
cannot accidentally start moving (chock the wheels)
and that the parking stand is in the right position.
The machine must only be attached to the hitch
points provided for this purpose.
Never stand between the tractor and the machine
when operating the three point linkage.
Do not stand between the machine and the tractor
or on the machine without having first applied the
tractor parking brake and placed the gearbox in the
neutral position.

4.2.9 Hydraulic circuit

Caution! The hydraulic circuit is under high
pressure. Maximum pressure at work: 200 bar
(2901 psi).
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. Damaged or worn hoses must
immediately be replaced. When replacing the
hydraulic hoses,
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.
