Batteries
Recommended battery sets BD 50/55
Low-maintenance batteries (wet batteries)
DANGER
Refilling discharged batteries with water
Danger of acid burns from escaping acid, destruction of
clothing
Wear safety goggles when handling the batteries.
Observe the applicable regulations.
Immediately rinse off any splashed acid from the skin or
clothing using copious amounts of water.
ATTENTION
Using water with additives
Defective batteries, loss of warranty eligibility
Top up the batteries using only distilled or desalinated
water (EN 50272-T3).
Do not use any foreign additives, so-called enhancing
agents, because this will invalidate the warranty.
1. Add distilled water one hour before the charging
process comes to an end. Observe the correct acid
level according to the battery label.
All cells must produce gas at the end of the charging
process.
Maintenance-free batteries (AGM and gel batteries)
ATTENTION
Risk of damage when opening AGM and gel batter-
ies!
AGM and gel batteries are maintenance-free and have
a closed battery housing. Refilling them with distilled
water or battery acid is not possible and is not neces-
sary. Opening or drilling the battery housing will damage
an AGM or gel battery. It must then be replaced.
Do not open the battery housing and do not drill any
holes.
Do not cover the pressure relief valve and do not
change it.
1. Only charge AGM and gel batteries using the spec-
ified chargers, see chapter: Charging the battery.

suit the degree of soiling of the floor covering.
Note
Perform initial cleaning tests with a low water volume.
Increase the water volume step by step until achieving
the desired cleaning result.
Note
The brush head continues operating without a liquid
supply if the fresh water tank is empty.
Adjusting the suction bar
Adjusting the inclination
The inclination must be adjusted so that the suction lips
of the suction bar make even contact with the floor over
the entire length of the suction bar.
1. Park the device on a surface without a slope.
2. Turn the key-operated switch to ON. Put down the
suction bar.
