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 danger of severe infections you
should always use appropriate aids when
looking for leaks.
¾
In order to rule out operating errors, the sock-
ets and plugs of function related hydraulic
connections between tractor and machine
must be marked with colours.
¾
In order to prevent accidents caused by un-
intended hydraulic movements, or hydraulic
movements triggered by external persons
(children, passenger), the control units on the
tractor must be secured and locked when not
in use or in transport position.
1.7.7 Electrical system
¾
Always disconnect the battery (negative pole)
before starting work in the electric system!
¾
Only use the specified fuses. The use of too
strong fuses destroys the electric system - fire
hazard!
¾
Ensure correct connection of the battery! Con-
nect the positive pole first and the negative
pole after. When disconnecting disconnect 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 open flames in the vicinity
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.
Please make sure that the subsequently
installed electric or electronic components
comply with the EMC-directive 89/336/EEC
in its valid version and are marked with the
CE-sign.
