Cleaning Machines KF75B, Manual

water to prevent foam from being created inside.

•  Do not leave the water hose unattended and insert

it completely into the tank: the hose might move and

get sensitive parts of the machine wet.

•  Close the tank cover.

To drain:

•  Open the valve located at the bottom of the machine

in the back and wait until the tank has been completely

emptied.

•  Fully tighten the drain valve.

7.5 DRAINING THE RECOVERY TANK

The dirty water must be drained in accordance with

national regulations.

The  user  is  completely  responsible  for  ensuring

compliance with such rules.

After the detergent solution is finished, always empty

the recovery tank before filling it again.

In general, the recovery tank can be emptied whenever

required, and even during intermediate phases of the

work cycle.

 Always empty the recovery tank before lifting it to

avoid  health  problems  for  operators  and  to  avoid

damaging the machine.

The recovery tank volume is higher than the detergent

solution volume, therefore a potentially dangerous

situation for the suction motor should never occur. In

any case, a safety float turns off the suction motor if

the dirty liquid level is too high.

 If water or foam starts leaking from under the tanks

for any reason, immediately turn off the suction motor

and empty the recovery tank.

To drain the tank:

Drive the machine to a suitable location to drain the

dirty water and preferably near a toilet or a sewer drain

(comply with the national regulations for waste water

disposal).

Turn off the machine and remove the key from the

panel.

Detach the drain hose from the hook and, keeping it

high, unscrew the plug.

Lower the drain hose toward the selected drainage

point.

The emptying operation can be interrupted quickly and

whenever required just by raising the drain hose.

Check the quantity of residual dirt in the tank and, if

necessary, clean the interior through the inspection

hole, lifting the cover.

Fully tighten the drain hose with the screw plug and

hang it on the support behind the machine.

 The top cover of the tank and the drain hose plug

must be airtight, otherwise the subsequent pressure

loss will reduce drying efficiency.

7.6 SEAT ADJUSTMENT

Check that the seat is in a stable position and firmly

secured.

7.7 DRIVING THE MACHINE

Select the running direction using the Forward/Reverse

lever.

Insert and turn the ignition key.

Using the right foot lightly press the accelerator pedal

and drive the machine to its destination.

Turn off the machine and remove the keys from the

control panel.

The  running  direction  can  be  changed  using  the

forward/reverse  lever,  even  while  pressing  on  the

accelerator pedal.

7.8 WORK METHOD

7.8.1 PREPARATION AND WARNINGS

Remove any loose solid residue from the surface to be

treated (using suitable tools, such as vacuum cleaners,

sweepers, etc.). It this is not done, the solid dirt might

prevent the squeegee from operating correctly, reducing

drying efficiency.

This machine can driven only by trained personnel.

7.8.2 OPERATING CONTROLS

•  Ignition key, to turn the machine on and off.

•    Direction  lever,  to  select  forward  or  reverse

movements.

•  Speed regulator, to select the maximum advancement

speed when the pedal is fully depressed.

•  Brush switch, to turn on the brush rotation motor.

•  Suction switch, to turn on the suction motor.

•  Emergency switch, to cut off/restart all programmed

work operations.

•  Right advancement pedal, to start moving the machine.

•  Solution flow adjustment lever, to regulate the quantity

 of detergent solution to be applied on the floor.

•    Battery  charge  control,  the  sequence  of  lights

progressively turns off until the battery is discharged.

When the red light turns on, turn off the brush motor,

close the solution supply, finish drying the small residual

moisture and go to the battery charging area to charge

the battery. If these operations are not carried out, the

machine will automatically deactivate the brush motor

and it will only be possible to move the machine. In this

situation if the machine is not stopped right away, all

functions will be cut off automatically, and the machine

will have to be moved by hand.

•     The batteries may be irreparably damaged if the

residual charge level drops too low (see the battery

operating manual). Do not force the battery discharge

beyond the safety limits, turning the key off and on or

in any other manner.

•    When an abnormal situation occurs, such as when

the machine doesn’t have enough power and the safety

devices  don’t  trip,  stop  immediately:  follow  the

instructions in the troubleshooting section and contact

a specialised worker to check the discharge control

devices.

7.8.3 DIRECT SCRUBBING OR FOR SLIGHTLY DIRTY

SURFACES

Scrubbing and drying in a single pass.

Prepare the machine as previously described.

Select the forward direction using the direction lever.

Insert and turn the key.

Activate the suction motor, the brush motor and the

detergent solution supply.

Lower the brushes and the squeegee.

Use the detergent adjustment lever to regulate the

solution outlet flow (depending on advancement speed).

Lightly press the advancement pedal and check that

all systems are working.

Fully depress the accelerator to increase the work

speed.

Adjust the maximum advancement speed and the

detergent solution flow as required.

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. § During these

operations, the rear of the machine moves slightly

outward: reduce the speed to avoid brusque direction

changes and impacts against walls or other objects.

Use the brake to stop the machine.

To avoid damage to the surfaces being treated, the

brush motor will stop automatically about 2 seconds

after the advancement pedal has been completely

released.

Never  use  the  machine  without  the  detergent

solution: the floor might be damaged.

7.8.4 INDIRECT SCRUBBING OR FOR VERY DIRTY

SURFACES

Scrubbing and drying in various passes.

Prepare the machine as previously described.

First set of operations:

Select the forward direction using the direction lever.

Insert and turn the key.

Activate the brush motor and the detergent solution

supply.

Lower the brushes.

Use the detergent adjustment lever to regulate the

solution outlet flow (depending on advancement speed).

Lightly press the advancement pedal and check that

the brushes and solution feed system are working.

Fully depress the accelerator to increase the work

speed.

Adjust the maximum advancement speed and the

detergent solution flow as required.

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.    During  these

operations, the rear of the machine moves slightly

outward: reduce the speed to avoid brusque direction

changes and impacts against walls or other objects.

Allow the detergent solution to work on the dirt according

to what is indicated in the information relative to the

detergent used.

Use the brake to stop the machine.

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 seconds

after the advancement pedal has been completely

released.

When moving in reverse, the squeegee will lift and

suction will be deactivated automatically. After changing

direction (forward direction), the squeegee and the

suction  will  automatically  return  to  their  previous

condition.

Never  use  the  machine  without  the  detergent

solution: the floor might be damaged

7.8.5 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 wiring.

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 instructions, 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 washing 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.

Detach the pocket and access the interior to pull out

the complete suction hose.

Now  you  can  wash  the  hose  and  remove  any

obstructions.

Firmly insert the suction hose inside the rear pocket,

in the special tank opening.

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.

Make sure that the compartment cover is tightly closed

after cleaning: the machine may not dry efficiently if the

cover is not properly closed.

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 constantly in this manner
