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 (H) on the operating
console 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.
Battery charging:
Release locking mechanism, and raise the tank. Remove the cover to the
electrics compartment.
Detach the battery plug and connect it to the charging cable. Switch the
battery charger on. The average charging time is 10–15 hours. The
recommended battery chargers (match whichever battery is fitted) are
electronically controlled and conclude the charging process automatically.
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 EXPLOSI-
ON!).
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.
