¾
Pressure accumulator
Depending on the equipment of the machine,
the hydraulic system may have a pressure ac-
cumulator installed. Do not open or work (weld-
ing, drilling) on the pressure accumulator. Even
after being emptied, the tank is still preloaded
by gas pressure. Always depressurize the
pressure accumulator before starting work on
the hydraulic system. The pressure gauge (if
present) should not indicate any pressure. The
pressure in the pressure gauge must drop to 0
bar. Only then may work be carried out on the
hydraulic system.
¾
Have the hydraulic hoses inspected by an ex-
pert under occupational safety related aspects
at least once every year!
¾
Replace hydraulic hoses if damaged or exces-
sively aged! Use only genuine hydraulic hoses
from HORSCH LEEB AS!
¾
The utilization period of hydraulic hoses
should not exceed six years, including a pos-
sible storage time of maximum two years.
Even if properly stored and under permissible
stress, hoses and hose connections are sub-
ject to natural ageing, which limits their shelf
life and utilization period. Deviating from this,
the utilization period can also be determined
on the basis of empirical values, particularly
under due consideration of the endangering
potential. For hoses and hose lines made of
thermoplastics other guide values may be
decisive.
¾
Never try to seal off leaking hydraulic hoses
with your hands or fingers. Fluids (hydraulic
oil) escaping under pressure can penetrate
the skin and enter into the body causing se-
vere injury! If injured by hydraulic oil, consult
a doctor immediately!
Danger of infection!
¾
Due to the possible danger of severe infec-
tions, one must use appropriate auxiliary
means when looking for leakages!
¾
Power sockets and connectors (electric,
pneumatic) should be identified by colour to
rule out operating errors.
¾
In order to avoid accidents caused by unde-
sired hydraulic movements or hydraulic move-
ments triggered by other persons (children,
passenger), the control units on the tractor
must be secured and locked when not in use
or in transport position.
1.6.7 Electrical system
Always disconnect the battery (negative pole)
before starting work in the electric system!
¾
Use only the specified fuses! The use of too
strong fuses will destroy the electric system.
Fire hazard!
¾
Make sure that the battery is correctly con-
nected. Connect the plus pole first and the
minus pole after. When disconnecting discon-
nect the negative pole first and the positive
pole after!
¾
Always cover the positive battery pole with the
dedicated covering.
Danger of explosion
in
case of short-circuit to ground!
¾
Avoid sparking and naked flames in the vicin -
ity of the battery!
Danger of explosion!
¾
The machine can be equipped with electronic
components and parts, the function of which
can be affected by the transmission of electro -
magnetic waves from other equipment. Such
influences can lead to the endangerment of
persons, if the following safety notes are not
complied with.
In case of a subsequent installation of electric
appliances and/or components on the ma-
chine, with connection to the on-board power
supply, the user in his own responsibility must
check whether this installation will cause
interferences in the vehicle electronics or in
other components.
Make sure that the subsequently installed
electric and electronic components are
in accordance with the valid issue of the
EMC directive 2014/30/EC and are identified
with the CE-sign.
