Kruger KF 675BBC, Manual

The steering wheel is similar to a car steering 

wheel: it can be used to turn the machine around 

itself by steering all the way to one side. 

Allow the detergent solution to work on the dirt 

according to what is indicated in the information 

relative to the detergent used.

Second set of operations:

Follow the steps described in the previous section 

“Direct Scrubbing” (7.8.3).

To avoid damage to the surfaces being treated, the 

brush motor will stop automatically about 2 sec-

onds after the advancement pedal has been com-

pletely released.



  Remember to lift the squeegee before 

driving reverse to avoid damaging it.

☞

 Never use the machine without the detergent 

solution: the floor might be damaged

7.7.5 POST-SCRUBBING 

OPERATIONS

Cut off the supply of detergent.

Lift the brush unit and turn off the brush motor.

After having completely dried any traces of water 

on the surface, wait a few seconds and then lift the 

squeegee and turn off the suction motor.

Move to a suitable location to drain the tanks (as 

described in 7.4 and 7.5).

Empty and clean the tanks (see sections 7.4 and 7.5).

Turn off the machine using the key and remove it 

from the control panel.

If necessary, charge the battery (see the relative 

section).

8. MAINTENANCE INFORMATION



 Turn the key, remove it from the control panel 

and disconnect the battery from the machine wir-

ing.

☞

 All work on the electrical system as well as all 

maintenance and repair operations (especially 

those not explicitly described in this manual) 

should be carried out only by authorised service 

centres or by specialised technical personnel who 

are experts in the sector and in the pertinent safety 

regulations.

Performing regular maintenance on the machine, 

and carefully following the manufacturer’s instruc-

tions, is the best guarantee for obtaining the best 

performances and extended machine service life.

8.1 TANKS

Drain the two tanks as described in the relative 

sections.

Remove any solid dirt by filling and draining the 

tanks until all dirt has been eliminated: use a wash-

ing hose or similar tool to do this.



  Water hotter than 50°, a high-pressure 

cleaner or excessively powerful sprays may 

damage the tanks and the machine.

Leave the covers of the tanks open (only while the 

machine is not being used) so that they can dry 

and thus prevent the formation of foul odours.

8.2 SUCTION 

HOSE

Detach the suction hose from the squeegee.

Pull out the suction hose from its connection hole 

placed in the recovery tank.

Now you can wash the hose and remove any ob-

structions.

After the cleaning, firmly insert again the suction 

hose inside connection hole placed in the recovery 

tank.

Firmly insert the hose on the squeegee body.

8.3 SQUEEGEE 



 Do not handle the squeegee with bare hands: 

wear gloves and any safety clothing needed to 

carry out the operation.

Detach the squeegee from the machine and clean 

it under running water using a sponge or a brush.

Check the efficiency and the wear on the strips in 

contact with the floor. They are designed to scrape 

the film of detergent and water on the floor and 

to isolate that portion of the surface to enhance 

the vacuum of the suction motor: this ensures that 

the machine will dry very efficiently. Working con-

stantly in this manner tends to round or to dete-

riorate the sharp edge of the strip, thus reducing 

drying efficiently. This is why the squeegee strips 

must be replaced.

To replace the worn straps, follow the instructions 

in the relative section. Turn the straps around to 

wear down the other sharp corners or to install 

new ones.

8.4 ACCESSORIES

Remove and clean the brushes or the scraper disks.



 To avoid damaging the floor and the machine, 

carefully check if foreign matter, such as metallic 

parts, screws, chips, cords or similar items, has 

become jammed.

Check that the brushes are flat as they work on 

the surface (check for any irregular wear on the 

brushes or on the abrasive disks). If necessary, ad-

just the slant of the action on the floor.

Use only the accessories recommended by the 

manufacturer: other products may reduce operat-

ing safety.

8.5 

CLEANING SOLUTION FILTER

Make sure that the detergent solution tank is 

empty.

Check and clean the solution filter located in the 

lower front part of the machine. Clean with running 

water if necessary and check that the detergent 

solution is being delivered on the brushes.

Fully tighten the filter to prevent leaks during op-

eration.

8.6 MACHINE 

BODY

Use a sponge or a soft cloth to clean the exterior of 

the machine and, if necessary, a soft brush to elimi-
