Hazard warnings

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 (12) on the
operating console (25) flashes red. The only remaining function is the
ability to drive the unit forwards or backwards. Drive the unit directly to
the charging bay, and avoid any ascending surfaces. In order to prolong
the life of the batteries, start the loading process immediately.
Charging the batteries:
Open unit cover, and detach the battery plug. Connect to the charging
cable, and switch charger on. The average charging time is 10 - 15
hours. The chargers recommended by us (match whichever batteries
are used!) are electronically controlled, and automatically switch off
when charging has been completed.
Never use battery chargers in the rain, in areas with high humidity, or
in damp rooms!
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!).
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 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.
