Maintenance and Service
Shutdown for a longer period of time
WARNING
Risk of burns.
Battery acid may cause dangerous burns on the skin and within the respiratory sys-
tem.
– When handling acid batteries, always wear approved personal protective equip-
ment (safety goggles, acid-proof gloves, apron) (See Page 37).
– Avoid skin contact with battery acid.
– Avoid inhaling acid vapours.
– When handling batteries, make sure that there is sufficient ventilation in the work-
place.
– In case of skin contact with battery acid, immediately flush the skin sections con-
cerned with lots of water. Then immediately consult a doctor.
– Uninstall the batteries. The batteries should be stored cool and dry, but protected
against frost. Before storing, check the acid level and, in case of need, fill up using
distilled water. Completely charge the batteries before storing them. Check the bat-
tery voltage once each month during storage and, in case of need, recharge the
batteries. Grease the battery terminals using a specific terminal grease.
DANGER
Warning against explosion hazard!
If acid batteries are improperly charged using unsuitable charging devices or too high
charging voltage, then this may lead to generation of oxyhydrogen gas. Oxyhydrogen
gas is very easily combustible and may explode.
– Always make sure of the correct charging voltage.
– Make sure that the batteries are only charged in well ventilated locations.
– Smoking, fire or open flame are strictly prohibited.
Batteries useful life
To preserve the starting ability of the batteries in case of a shutdown period of more
than 2 weeks, the following notes must be observed:
– Check the liquid level. If it is too low, then exclusively fill up with distilled water to
the maximum acid level mark.
– The self-discharge rate amounts to about 0.2% of the nominal capacity/day at
20°C.
– To avoid deep discharge, the acid density must be checked at regular intervals. If
the acid density is below 1.21 kg/l, then the batteries must be recharged. The rec-
ommended charging current is 1/10th of the capacity.
– Deep discharged batteries form lead sulphate. Regeneration by recharging is no
longer possible.
– In case of batteries forming sulphate, detectable by the silver-coloured plate coat-
ing and turbid battery acid, there are neither guarantee nor warranty claims. They
are also excluded from any accommodation scheme, because this damage is
caused by gross negligence during maintenance.
ADVICE
After a shutdown of up to 6 months, the machine must be put into operation for
at least 30 minutes.
•
Leave diesel engine running for at least 30 minutes!
•
Allow the machine drive to run for a few minutes.
•
It is also recommended to drive the machine at least 1 km on the road.
