Jungheinrich DFG 320 Operating Instructions Manual page 81

Work on the electric system: Only suitably trained personnel may operate on the
truck's electrical system. Before working on the electrical system, take all
precautionary measures to avoid electric shocks.
Welding: To avoid damaging electric or electronic components, remove these from
the truck before performing welding operations.
Settings: When repairing or replacing hydraulic, electric or electronic components or
assemblies, always note the truck-specific settings.
Tyres: The quality of tyres affects the stability and performance of the truck. When
replacing tyres fitted at the factory, only use the manufacturer's original spare parts.
Otherwise the data sheet specifications of the truck cannot be guaranteed. When
changing wheels and tyres, ensure that the truck does not slew (e.g. when replacing
wheels always left and right simultaneously).
Lift chains: Lift chains wear rapidly if not lubricated. The intervals stated in the
service checklist apply to normal duty use. More demanding conditions (dust,
temperature) require more regular lubrication. The prescribed chain spray must be
used in accordance with the instructions. Applying grease externally will not provide
sufficient lubrication.
Hydraulic hoses: The hoses must be replaced every six years. When replacing
hydraulic components, also replace the hoses in the hydraulic system.
Starter battery disposal: Batteries may only be disposed of in accordance with
national environmental protection regulations or disposal laws. Do not dispose of
used batteries with general waste. The manufacturer's specifications for the disposal
must be heeded. End users, both private and commercial, are legally obliged to return
used truck starter batteries to the battery manufacturer through the trade, i.e.
wherever batteries are sold, or through authorized disposal agents. If in doubt,
contact the Jungheinrich service department.
