WARNING
Danger of causticization!
– Adding water to the battery in its discharged state can cause the acid to leak.
– Use safety glasses while handling battery acid and follow the safety instructions to avoid personal 
injury or damage to clothes.
– Should the acid spray on to the skin or clothes, rinse immediately with lots of water.

ATTENTION
Risk of damage!
– Use only distilled or desalinated water (EN 50272-T3) for filling the battery.
– Do not add any substances (so-called performance improving agents), else warranty claims will not be 
entertained.
– Replace batteries with the same battery type only.

Installing the Vacuum Bar

• Insert the vacuum bar into the vacuum bar suspension in such a manner that the profiled sheet is 
positioned above the suspension.
• Tighten the nuts.

• Insert the suction hose.

Install batteries

Install the batteries (see "Care and Maintenance/Install and connect batteries").

Using batteries made by other manufacturers

We recommend using our batteries as described in chapter "Care and Maintenance/ Recommended 
batteries".

Charging battery

NOTE: The device is equipped with a safety mechanism to prevent total discharge, i.e. when the permis-
sible minimum capacity is reached, the brush motor and the turbine are switched off.

• Drive the machine directly to the charging station; avoid any steep gradients in the process.

DANGER
Danger of injury due to electric shock. Observe the mains voltage and fuse protection on the type plate of 
the device.

Charging process
