Maintenance
Instructions concerning specific components
Cables, bulbs and fuses
Always observe the following instructions:
• Malfunctioning components of the electrical system must always be replaced by a
Wacker Neuson service center. Lamps and fuses may be replaced by unqualified
persons
• When performing maintenance on the electrical system, pay particular attention to
ensuring good contact in leads and fuses
• Blown fuses indicate overloading or short circuits. The electrical system must therefore
be checked before installing the new fuse
• Only use fuses with the specified load capacity (amperage)
–see“Fuse box at the right under the control stand behind the side trim” on page 2-5
Always disconnect and remove the battery before performing welding work on the
machine, and short-circuit the terminal cables of the machine to avoid damage to
the electronic components.
Alternator
Observe the following instructions:
• Start the engine only if the battery is connected
• When connecting the battery, ensure that the poles (+/−) are not inverted
• Always disconnect the battery before performing welding work or connecting a quick
battery charger!
• Replace malfunctioning charge indicator lights immediately
–see“Alternator charge function indicator light (red)” on page 1-12
