Low Maintenance (Lead-Acid) Batteries
Charging Process
Using Batteries Made by
Other Manufacturers
Mount the batteries (see “Care and
Maintenance/Mounting and Connecting the
Batteries”). Optional battery*.
*Check with one of our resellers.
We recommend using our batteries
as described in chapter “Care and
Maintenance/Recommended Batteries.”
Warning:
The device is equipped with a total
discharge protection, that is, if the minimum
admissible capacity is reached, the brush
motor and the turbine are switched off.
Take the device directly to the charging
station, avoiding any unnecessary
steep gradients.
Average charging time is approx. 10 to 15
hours. The device must not be used during
the charging process.
DANGER
Danger of injury due to electric shock.
Observe the mains voltage and fuse
protection on the device type plate.
DANGER
Explosion risk
Before starting to charge low-
maintenance batteries, remove the
waste water tank (see the chapter “Care
and Maintenance/Maintenance Work/
Removing the Waste Water Tank”). This
prevents the accumulation of hazardous
gases underneath the tank during the
charging process.
WARNING
Damage risk. Do not clean the device with
water while the tank is removed.
ATTENTION
Risk of burns!
- Adding water to discharged
battery can cause the acid to leak.
- Use safety glasses while handling
battery acid and follow the current safety
instructions to avoid personal injury or
damage to clothes.
- Should the acid spray on to the skin or
clothes, rinse immediately with plenty of
running water.
WARNING
Damage risk!
- Use only distilled or desalinated water in
the batteries.
- Do not add any unknown additives (the
so-called performance improving agents)
or the warranty will be deemed void.
- Replace batteries with the same battery
type only.
