Install batteries

Install the batteries (see "Care and Mainte- nance/Install and connect batteries").

Using batteries made by other manufacturers

We recommend using our batteries as de- scribed in chapter "Care and Maintenance/ Recommended batteries".

Charging battery

Note: The device is equipped with a safety mech- anism to prevent total discharge, i.e. when the permissible minimum capacity is reached, the brush motor and the turbine are switched off.

→ Drive the machine directly to the charg- ing station; avoid any steep gradients in the process.

DANGER

Danger of injury due to electric shock. Ob- serve the mains voltage and fuse protec- tion on the type plate of the device.

Charging process

Average charging time is approx. 10 -15 hours.

The appliance must not be used during the charging process.

DANGER

Danger of explosion

Prior to charging low-maintenance bat- teries

Remove waste water tank (see Chapter "Maintenance and care/Maintenance tasks/Removing the waste water tank").

This prevents the accumulation of hazard- ous gases underneath the tank during the charging process.

ATTENTION: Risk of damage. Do not clean the device with water while the tank is removed.

1. Battery plug, appliance side
2. Battery plug, battery side

→ Detach the battery plug on the unit side.

ATTENTION

Risk of damage!

• Do not connect the charger with the battery plug on the unit side.
• Only use a charger that is suitable for the installed battery type:

Note: Please read the operating instructions of the charger manufacturer, especially the chapters on safety instructions!

→ Connect the battery plug on the battery side with the charger.

→ Plug the mains plug of the charger into a power outlet.

→ Execute the charging process according to the information in the operating instructions of the charger.

→ Connect the battery plug on the device side with the battery plug on the battery side.

Low maintenance batteries (wet batteries)

WARNING

Danger of causticization!

• Adding water to the battery in its discharged state can cause the acid to leak.
• Use safety glasses while handling bat- tery 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 wing nuts.

→ Insert the suction hose.

Operation

DANGER

Risk of injury!

In dangerous situations, release the safety switch/drive lever.

Filling in detergents

Fresh water

→ Open the lock of the fresh water reservoir.

→ Fill fresh water (maximum 60 °C) until the lower edge of the filling nozzle.

→ Close the lock of the fresh water reservoir.

Detergent

WARNING

Risk of damage. Only use the recommended detergents. With other detergents, the operator bears the increased risk regarding the operational safety and danger of acci- dent.

Only use detergents that are free from sol- vents, hydrochloric acid and hydrofluoric acid.

Follow the safety instructions for using detergents.

Note: Do not use highly foaming detergents.

Recommended detergents:

→ Add the detergent to the fresh water reservoir.

Note: If the fresh water tank is empty, the cleaning head continues working without liquid supply.

Setting the water quantity

→ Adjust the water quantity using the regulating button according to the dirt on the floor covering.

Note: Carry out initial cleaning attempts with low water volume. Increase water volume step- by-step until the desired cleaning result is achieved.

Setting the Vacuum Bar

Oblique position

To improve the vacuuming result on tiled floors the vacuum bar can be turned to an oblique position of up to 5°.

→ Loosen the wing nuts.

→ Turn the vacuum bar.

→ Tighten the wing screws.

Inclination

If the vacuum result is unsatisfactory the inclination of the straight vacuum bar can be modified.

→ Adjust the rotary handle to incline the suction bar.

Height

The bend of the suction lips upon contact with the floor is influenced with the height adjustment.

→ Try adjusting the twist handles of the height adjustment until the best vacuuming result is achieved.

Cleaning

ATTENTION: Risk of damage to the floor covering. Do not operate the appliance on the spot.

→ Swivel the pedal for the transport chassis down.

→ Turn the program selection switch to the desired cleaning program.

Lower the vacuum bar

→ Pull the lever out and press it down; the vacuum bar is lowered.

Note:

• For cleaning tiled floors, adjust the straight suction bar in such a way that cleaning is not done at an angle of 90 degrees to the joints.
• The inclined position and the inclination of the suction bar can be adjusted to achieve better suction results (see "Adjusting the suction bar").
• If the waste water tank is full, the float closes the suction opening and the suction turbine runs at an increased speed. If this is the case, shut the vacuum off and drive to empty the waste water tank.

Shutting Down the Appliance

→ Release the safety switch.

→ Set the program selection switch to suction or vacuuming.

→ Briefly drive forward and suck of the remaining water.

→ Raise the vacuum bar.

→ Charge battery, if required.

Drain off dirt water

WARNING: Please observe the local provisions regarding the wastewater treatment.

→ Take the water discharge hose from the support and lower above a suited collection device.

→ Crush or bend the dosing equipment.

→ Open the lid of the dosing equipment.

→ Drain off the dirt water - regulate the water quantity by pressing or bending.

→ Rinse the waste water tank with clear water.

Drain off clean water

→ Unscrew the lock of the fresh water reservoir.
