Function

The scrubbing vacuum cleaner is used for the wet cleaning of level floors.

The device can be easily adjusted to the respective cleaning task by adjusting the water volume and the detergent volume.
The detergent dosing unit can be adjusted via the addition in the tank.
The device is equipped with a fresh water and a waste water tank (50 liters each). These allow an effective cleaning with a long usage life.
A working distance of 500 mm will improve the efficiency when you are using the appliance for a long period. Propulsion is accomplished by manual-ly pushing the appliance and is supported by the rotation of the brushes. The brush drive is powered by two batteries. Batteries can be selected depending on the configuration (refer to Chapter “recommended batteries”)

Note:
The appliance can be equipped with various accessories depending on the cleaning task.
Please request our catalogue or visit us on the Internet at www.kaercher.com.

Proper use

Use this appliance only as directed in these operating instructions.

The appliance may only be used for the cleaning of hard surfaces that are not sensitive to moisture and polishing operations.
The appliance is not suited for the cleaning of frozen grounds (e.g. in cold stores).
The appliance may only be equipped with original accessories and spare parts.
The appliance is not suited for the use in potentially explosive environments. The machine should not be used to suck in inflammable gases, undiluted acids or solvents.
This includes petrol, thinning agents or hot oil that can form an explosive mixture when it comes in contact with sucked air. Do not use acetone, undiluted acids and solvents as they are aggressive towards the materials from which the appliance is made.

Before Startup

Unloading

Unscrew the screws from the middle board of the pallet.
Push down the device holding the push handle and pull out the middle board.
Remove the chocks in front of and next to the wheels.
Push down the device holding the push handle and push it forwards up to the edge of the pallet.
Lift the device off the pallet and set it on the floor.

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 permissible 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. Ob-serve the mains voltage and fuse protection 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 batteries
Remove waste water tank (see Chapter “Maintenance and care/Maintenance tasks/Removing the waste water tank”). This prevents the accumulation of hazardous gases underneath the tank during the charging process.

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

Battery plug, appliance side
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:
Battery type| Charger
---|---
6.654-141.0| 6.654-333.0
6.654-093.0| 6.654-329.0
6.654-290.0| 6.654-332.0

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 dis-charged 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 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 accident.
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:

Application	Detergent
Routine cleaning of all water resistant floors	RM 746

RM 780

Routine cleaning of glossy surfaces (e.g. granite)| RM 755 es
Routine cleaning and basic cleaning of industrial floors| RM 69 ASF
Routine cleaning and basic cleaning of fine stoneware tiles| RM 753
Routine cleaning of tiles in sanitary areas| RM 751
Cleaning and disinfection in sanitary areas| RM 732
Removal of coating from all alkali-resistant floors (e.g. PVC)| RM 752
Removal of coating from linoleum floors| RM 754

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 col-lection device.
Crush or bend the dosing equipment.
Open the lid of the dosing equipment.
