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, 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.

4.2.10 PTO shaft
Use only PTO shafts supplied with the machine or
recommended by the machine manufacturer.
The protective shield of the tractor PTO stub, the
PTO shaft guards and the protective shield of the
machine input shaft must always be in place and in
good condition.
Make sure that the PTO shaft guards are secured
with the safety chains provided. Check that the PTO
shaft guard can turn freely a full rotation
independent of the shaft.
Any worn or damaged guards must be replaced
immediately. A worn guard or an unprotected PTO
shaft can cause a serious or even a lethal accident.
Do not wear loose clothing that could be caught in
the rotating PTO shaft.
Before attaching or removing a PTO shaft, or before
doing any work on the machine, disengage the PTO
drive, turn off the engine, remove ignition key and
wait for all moving parts to come to a complete stop.
If the primary PTO shaft is equipped with a torque
limiter or a free wheel, these must be fitted on the
machine side.
Ensure that the PTO shaft is always correctly fitted
and locked into place.
Before connecting the PTO shaft, ensure that the
PTO speed (rotational frequency) and direction of
rotation are in line with the machine manufacturer's
recommendations.
Before engaging the PTO drive, make sure that
there are no people or animals near the machine.
Never engage the PTO drive when the tractor
engine is stopped.
