Maintenance
Instructions concerning specific components
Cables, lamps 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 a new fuse.
• Only use fuses with the specified load capacity (amperage)
– see chapter Fuses behind the right-hand trim on page 6-4
