General Safety Instructions
Specic Cautions and Warnings are included to warn you of potential danger of machine damage or bodily
harm.
Warning!
• This machine is to be used only by correctly trained and authorized persons.
• Avoid sudden stops while on ramps or inclines when the tanks are full. Avoid abrupt sharp
turns. Use low speed down hills. Clean only while ascending (driving up) the ramp.
• Keep sparks, flame and smoking materials away from batteries. Explosive gases are vented
during normal operation.
• Charging the batteries produces highly-explosive hydrogen gas. Charge batteries only in
well-ventilated areas, away from open flame. Do not smoke while charging the batteries.
• Remove all jewelry when working near electrical components.

General Information 12Service Manual – SC6500™
• Turn the key switch off (O) and disconnect the batteries before servicing electrical
components.
• Never work under a machine without safety blocks or stands to support the machine.
• Do not dispense flammable cleaning agents, operate the machine on or near these agents, or
operate in areas where flammable liquids exist.
• Only use the brushes provided with the machine or those specified in the instruction manual.
The use of other brushes may impair safety.
Caution!
• This machine is not approved for use on public paths or roads.
• This machine is not suitable for picking up hazardous dust.
• Do not use scarifier discs and grinding stones. Advance will not be held responsible for any
damage to floor surfaces caused by scarifiers or grinding stones. (This can also damage the
brush drive system.)
• When operating this machine, ensure that third parties, particularly children, are not
endangered.
• Before performing any service function, carefully read all instructions pertaining to that
function.
• Do not leave the machine unattended without first turning the key switch off (O), removing
the key and applying the parking brake.
• Turn the key switch off (O) and remove the key before changing the brushes, and before
opening any access panels.
• Take precautions to prevent hair, jewelry or loose clothing from becoming caught in moving
parts.
