BATTERIES
The unit contains circuitry that provides protection
against over-discharging the batteries; i.e., when the
minimum permissible battery capacity has been
reached, the brush motors and the turbine are switched
off. In this case the battery charge indicator on the
operating console flashes red.
Push the scrubber to the charging station and recharge the
battery.
Never use battery chargers in the rain, in areas with
high humidity or in damp rooms!
Hazard warnings
Naked flames, activities that might generate sparks,
and smoking is strictly forbidden in the vicinity of
batteries or in a charging room (DANGER OF
EXPLOSION!).
Any cuts or abrasions should not be allowed to come
into contact with lead; always wash hands thoroughly
after working on batteries.
Never deposit tools or similar objects on top of batteries;
i.e., on terminals and cell connections (DANGER OF
SHORT CIRCUIT AND EXPLOSION!).
The following information applies to batteries
that are NOT maintenance-free:
Always add distilled water about one hour before the
charging process is due to end. Check that the acid
content is correct. The batteries are marked
correspondingly. Adding water to a discharged battery
can cause acid to escape.
Observe whether bubbles form in all the cells when
charging has been completed. Measure the acid density
of each cell every 4 weeks.
Batteries should only be charged with the unit cover
opened (DANGER OF EXPLOSION!).
Always use chemically pure battery acid (as per VDE
0510) with a density of 1.28 kg/L.
Use only distilled or desalinated water (VDE 0510) to
dilute the sulphuric acid.
Never use any additives (so-called enhancing agents)
otherwise the guarantee will be void. Take special
care when handling battery acid (danger of injury and/
or damage to clothing!), use protective goggles, and
observe relevant regulations! If any acid touches skin
or clothing, rinse immediately with plenty of water.
Please dispose of battery or rechargeable
battery in an environmentally friendly manner
Batteries and rechargeable batteries contain
substances which must not pollute the
environment. Please therefore dispose of
batteries via suitable collection systems.
Charge battery
BR/BD 530 BAT/ BR/BD 53/40 W
Open the reservoir catch – turn the socket-head screw with
the supplied key and tip up the reservoir.
Important: Before tipping up the reservoir please pull away
the suction hose on the suction bar (Danger of snapped
hose!).
Clamp the charging device to the batteries and switch on,
ensure correct polarity! On average, charging takes 10–
15 hours. The charging devices recommended by us
(suited to the batteries being used!) are electronically
regulated and terminate the charging process automatically.
