Hydraulic Connections
•
Do not connect hydraulic lines to the tractor
before both hydraulic systems (machine and
tractor) are depressurized.
•
The hydraulic system is under high pressure.
Check all lines, hoses and screwed
connections regularly for leaks and any
visible external damage!
•
Only use appropriate aids when checking for
leaks. Repair any damage immediately! Oil
sprays can cause injuries and fire!
•
In the case of injury, contact a doctor
immediately!
The control units on the tractor
must be secured or locked
when not in use or when the
machine is in transport
position, in order to prevent
accidents caused by
unintended hydraulic
movements or movements
caused by persons other than
the operator (children,
passengers).
Pressure Accumulator
Depending on the equipment of the machine, the
hydraulic system may have a pressure
accumulator installed.
Do not open or work (welding, drilling) on the
pressure accumulator. Even after being emptied,
the accumulator is still preloaded by gas
pressure.
Always depressurize the pressure accumulator
before starting work on the hydraulic system.
The pressure gauge should not indicate any
pressure.
The pressure gauge reading should drop to 0
psi. Only then may service be carried out on the
hydraulic system.
Service and Maintenance
• Ensure that regular tests and inspections are
always carried out to schedule, as specified in
the operating instructions.
• Prior to performing maintenance and servicing
work, ensure that the machine is positioned on
firm, level ground and that it is properly
secured against rolling away.
• Depressurize the hydraulic system and lower
or support the implement.
• After cleaning, check all hydraulic lines for
leaks and loose connections.
• Check hoses for chafing and signs of other
damage. Remedy any faults immediately!
• Prior to working on the electrical system,
disconnect it from the electric power supply.
• Retighten screwed connections which had
been loosened during servicing and
maintenance work.
Do not wash new machines
with a steam-jet or high-
pressure cleaner. The paint
takes approximately 3 months
to cure and could thus be
damaged if this time has not
yet expired.
