Instructions concerning specific components
Cables, lamps and fuses
Always observe the following instructions:
• Defective components of the electrical system must always be replaced by an
authorised expert. Lamps and fuses may be replaced by the customer.
• When carrying out maintenance work 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.
