• The utilization period of hydraulic hoses should not
exceed six years, including a possible storage time
of maximum two years. Even if properly stored and
under permissible stress, hoses and hose connec-
tions are subject 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.
• Never try to seal off leaking hydraulic hoses with
your hands or fingers. Fluids (hydraulic oil) es
-
caping under pressure can penetrate the skin and
enter into the body causing severe injury!
Immediately consult a physician if injured by hy-
draulic oil! Danger of infection.
• When checking for leaks use appropriate aids, be-
cause of the possible risk of severe infection.
• Power sockets and connectors (electric, pneumatic)
between Trac and machine should be colour-coded
in order to exclude operating errors.
• The control unit on the Trac 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 op-
erator (children, passengers).
2.7.7 Electric system
• Always disconnect the battery (negative pole) be-
fore starting work in the electric system!
•
Use only the specified fuses. The use of too strong
fuses will damage the electric system - fire hazard!
• Ensure correct connection of the battery - connect
the positive pole first and the negative pole after!
When disconnecting disconnect the negative pole
first and the positive pole after!
• Always cover the positive pole of the battery with
the cover intended for this purpose. Danger of ex-
plosion in case of short-circuit to ground!
• Danger of explosion! Avoid the creation of sparks
and naked flames in the vicinity of the battery!
• The machine can be equipped with electronic
components and parts, the function of which can
be affected by the transmission of electromagnetic
waves from other equipment. Such influences can
lead to the endangerment of persons, if the follow-
ing safety notes are not complied with.
o When subsequently installing electric equip-
ment and/or components to the machine, including
the connection to the vehicle electrics, the user
must check in his responsibility whether the instal-
lation causes interferences in the vehicle electrics
or with other components.
o Make sure that the subsequently installed elec-
tric and electronic components are in accordance
with the valid issue of the EMC-directive 2004/108/
EEC and are identified with the CE-sign.
2.7.8 Battery
• Maintenance work on the battery requires appropri-
ate knowledge and proper tools!
•
Keep open fire, burning matches and sparks away
from the battery;
Danger of explosion!
• Never check the charge level of the battery by
connecting both poles to a metal object. Use a
Voltmeter.
• Do not recharge a frozen battery;
Danger of explosion!
Heat the battery up to 16 °C
beforehand.
• Battery acid can cause severe injury by cauteriza-
tion of skin and eyes, you should therefore wear
appropriate protective clothing.
2.7.9 Cooling system
The heated up cooling system is under pressure –
Dan-
ger of burning!
- you should therefore only remove
the radiator cap with the engine shut down and cooled
down.
