1. IMPORTANT WARNINGS:
1.1. IMPORTANT! This appliance is not suitable for removing dusts
hazardous to health.
1.2. IMPORTANT! This appliance is not suitable for washing carpet or
textile floors or wood floors not treated with non-absorbent resin.
1.3. This appliance is not approved for use on public roads or highways.
1.4. This appliance may only be used by personnel fully trained in its
correct and appropriate use.
1.5. In order to prevent unauthorised use of the machine always remove
the key from the key switch before leaving the appliance
unattended.
1.6. Lower the brushes before leaving the machine unattended to prevent
accidental movement.
1.7. When using the machine the operator should take care not to
endanger any third persons, particularly children.
1.8. The appliance may not be used on slopes of greater than 2%.
1.9. We expressly draw your attention to the fact that original parts and
accessories not supplied directly by Gansow have not been tested
or authorised by Gansow.
The installation and/or use of such items may therefore adversely
affect the efficiency and characteristics of your floor cleaning
machine, jeopardising its active and passive safety.
The manufacturer declines all liability for damage occurring as a
result of the use of non-original parts or accessories.
1.10. Before any cleaning or servicing work is carried out on the machine,
the following precautions must be taken:

6 ENGLISH
-unplug the plug from the charger from the charger
socket; -remove the key from the control panel.
ATTENTION !
Before changing the main fuse, disconnect the battery cables from
the respective terminals (danger of short circuit).
1.11. Under no circumstances may the charger leads (connecting the
charger to the machine) supplied be modified.
1.12. All electrical functions of the machine are interrupted immediately as
soon as the plug is plugged into the charger socket.
1.13. This appliance may be used with the brushes provided by the
producer only.
ATTENTION !
The safety of the appliance will be jeopardised by the use of other
brushes.
1.14. *IMPORTANT - battery gas is highly explosive; -
avoid sparks or open flames close to the batteries!
To avoid the build-up of gas inside the machine, the tank and tank
lid must remain in the raised position throughout charging. The
caps of all battery cells must also be unscrewed and/or removed
(not necessary in the case of gel batteries).
1.15. *IMPORTANT - battery acid is corrosive!
When topping up with distilled water make sure the level of liquid is
the same in all the battery cells. Dry cells shorten battery life and
may cause irreparable damage to the entire battery (not relevant to
gel batteries).

ENGLISH 7
1.16. IMPORTANT! Rooms where batteries are being charged should
always be well ventilated.
* Not relevant to maintenance free gel
batteries
2. INSTRUCTIONS BEFORE OPERATING:
2.1. Before operating a battery-powered machine, please read all the
following instructions and the instructions for use of the charger (if
purchased).
2.2. Note that the batteries deliver maximum power only after eight to ten
charging cycles. During this period, the machine should not
therefore be used for excessively heavy cleaning.
2.3. To provide your battery with even greater protection, the machine is
equipped with a charge indicator and hour counter.
By means of variously coloured LEDs (seven yellow and one red),
this provides a constant indication of the charge and automatically
shuts the brush motors down when the charge drops below the
safety level.
The LEDs indicate the following stages:
YELLOW ON: batteries within the charge limit
YELLOW FLASHING 15 seconds of running time remain before the brush
motors shut down.
RED ON: the battery is flat and the brushes are blocked. You should
immediately go to the charging area to avoid damaging the batteries.

8 ENGLISH
The transition of one LED to another with a delay of just 15 seconds
ensures a prompt response in the event of flat batteries to avoid
discharging them further and therefore irreparably reducing their working
life.
2.4. IMPORTANT! The machine must not under any circumstances be
started up with the front and top lids raised.
3. PRACTICAL GUIDE FOR THE OPERATOR:
3.1. *IMPORTANT - Seal the battery cells by screwing on the caps.
* Not relevant to maintenance free gel
batteries
3.2. After turning the charger off, unplug the connection lead from the
charger from the battery socket to power the machine.
3.3. Lift the top lid and use a hose or bucket to fill the clean water tank (on
the left) with cold water up to a maximum of 3 cm from the top of
the tank (the water should preferably be cold and in any case never
hotter than 60°C).
IMPORTANT!
Use low foam detergent as excessive foam could
jeopardise the efficiency and function of the machine.
Close the top lid, lifting slightly on the hinge side to make sure it fits
perfectly to the tank.
IMPORTANT! If the lid does not fit perfectly, there would be no
vacuum at the squeegee and therefore no flow-back of liquid to the
collection tank (on the right). If necessary, repeat the operation
correctly.
Avoid resting heavy objects on the lid as this could warp it and
prevent it from fitting perfectly to the tank.

ENGLISH 9
3.4. Make sure the cap of the dirty water tank (on the right) drain hose is
correctly in place. Perfect closure of the cap is essential to obtain a
vacuum in the collection tank and therefore maximum suction
power.
3.5. Turn the key switch clockwise to start the machine.
3.6. Light pressure and a slight sideways movement of the pedal release
the brushes which are lowered in contact with the ground.
3.7. To activate brush rotation, press the corresponding button on the left
side of the control panel.
MACHINES WITH DIAPHRAGM: Pressing this button opens the
water solenoid valve and turns the water pump on.
Turn the knob on the control panel clockwise to adjust the
quantity of water to the brushes (from 0 to 7 litres).
MACHINES WITHOUT DIAPHRAGM: Pressing this button opens the
water solenoid valve.
To adjust the quantity of water to the brush in accordance with
the dirt to be removed (more dirt=more solution), use the red
lever at the bottom on the operator's right. When the lever is
horizontal, the cock is fully open, when vertical it is completely
closed.
3.8. Lower the squeegee to the ground, using the control lever in front of
the operator under the handle.
3.9. Turn on suction to convey the dirty water to the collection tank, using
the button marked with a fan on the right of the control panel.

10 ENGLISH
4. INSTRUCTIONS:
4.1. SERIES "B" MODELS WITHOUT DRIVE:
The appliance is equipped with a patented drive system - as the
brush rotates in contact with the ground, it draws the whole
machine along at the correct working speed.
By pushing slightly, the drive speed can be increased as required.
Holding it back slows it down.
SERIES "BF" MODELS WITH DRIVE:
Push the drive lever gradually forwards to advance the machine at
the required speed. The maximum possible speed is 5.5 km/h.
On curves, adjust speed by moving the drive lever backwards.
When the lever is released completely, the drive motor stops
automatically.
ATTENTION!
The drive unit is fitted with a crush prevention device consisting of a
square red button at the centre of the handle which changes the
direction of movement if touched while the appliance is in reverse.
This prevents the operator being crushed in the event of incorrect
manoeuvres.
4.2. Clean in parallel strips overlapping by 3 to 4 cm.
Rollers on the ends of the squeegee act as bumpers and also
enable you to clean at a tangent to the edges. The extreme
manoeuvrability of the squeegee which can be swung freely and
widely to both sides enables you to clean around any obstacle. The
squeegee then returns to the central position when the obstacle or
curve has been passed. When consigning the machine or during a
demonstration, our service technician can advise you on the best
way of cleaning your own particular floor surface.

ENGLISH 11
4.3. By means of a vacuum created inside the collection tank, the used
water and the dirt are completely absorbed and conveyed to the
dirty water tank.
To prevent dirty water or foam damaging the vacuum motor, the
collection tank is protected by two sensors (electrodes) which shut
the machine down when the tank is full (they also detect the level of
any foam present).
4.4. After finishing the work or when the solution in the tank is used up
(indicated with a red flashing light on the switch board), stop brush
rotation by pressing the corresponding button. This also stops the
flow of water. Raise the head using the pedal.
4.5. To collect the remaining dirt, continue for a further 3-4 metres with
suction activated and the squeegee lowered, than turn both
functions off by pressing the suction button and raising the
squeegee lever. This empties all water left in the circuit into the
collection tank.
IMPORTANT!
After you have finished cleaning, you are recommended to raise the
tank lid and turn the suction motor on again for a few minutes. The
dry air sucked in will evaporate any remaining moisture, extending
the working life of the motor.
4.6. Empty the collection tank into a container or drain using the black drain
hose and proceeding as follows:
-detach the hose from the control panel;
-keeping the hose raised above the level of the tank at all times,
remove the cap;
-lower the hose gradually towards the container.
4.7. IMPORTANT! After each cleaning session, you are recommended to
drain the dirty water and rinse the tank to avoid unpleasant smells
or the formation of harmful germs. To make this operation faster,

12 ENGLISH
simpler and more effective, the appliance is fitted with an
exclusive system:
-the tank tilts backwards, after raising the lid, lift the tank until it rests
on the chassis (empty before tilting);
-after removing the cap, lower the drain hose to allow the water to run
off rapidly;
-wash the collection tank with running water;
-leave the tank tilted until the next time you use the machine.
The appliance has been designed to facilitate thorough
maintenance. A little attention improves the efficiency of your
appliance and extends the already long working life.

ENGLISH 13
4.8. When parking the machine, you are recommended to lower
the brush head to anchor it to the ground.
4.9. The machine has a rapid brush replacement system:
1- turn the key to the off position (anticlockwise as far as it will go),
2- use the pedal to lift the brush head,
3- hold the brush with both hands and turn it sharply in the normal
direction of rotation. In the case of heads with two motors, the
direction of rotation is always towards the centre of the head.
Hold the bayonet coupling firmly in position and release the
brush.
4- remove the brush and position the replacement in the centre of
the housing, precisely under the bayonet coupling,
5- use the pedal to raise the brush head,
6- switch the appliance on and activate brush rotation for a few
moments, then turn off again,
7- finally, raise the brush head and make sure the brush is correctly
fitted. If necessary, repeat operations 1 to 6.
4.10. The key switch should be turned off before recharging the
batteries.
4.11. In order to avoid any build-up of gas inside the machine,
the tank (previously emptied) covering the batteries must
be raised and remain in that position throughout charging.
Similarly, the caps of all battery cells must also be
unscrewed and/or removed (not necessary in the case of
maintenance-free gel batteries).
PRECAUTIONS
Battery gas is highly explosive. Avoid sparks and open flames near
the batteries.
When topping up with distilled water make sure the level of liquid is the

14 ENGLISH
same in all the battery cells. Dry cells shorten battery life and may cause
irreparable damage to the entire battery (not relevant to maintenance-free
gel batteries).
ATTENTION!
If the battery is damaged, the acid is highly corrosive!
4.12. IMPORTANT! Rooms where batteries are being charged
should always be well ventilated.
Before using battery-powered models, read carefully the
instructions on use and maintenance of the machine, batteries and
charger; procedures and precautions to be observed while charging
batteries and connecting the charger and inspection and
maintenance of batteries and maintenance schedules.

ENGLISH 15
5. TROUBLESHOOTING:
5.1. No water is delivered, check that:
-the brush is moving,
-if necessary, activate the brush by using the button on the left of the
control panel,
-there is water in the tank and the level is above the filter (the red LED
on the switch board is flashing),
-if necessary, top up and add detergent,
-the clean water filter is not clogged,
-if necessary, remove and clean with air from the outside inwards,
-the water solenoid valve is operating correctly,
-if necessary, remove and clean,
-the water cock is open (lever horizontal = fully open, lever vertical =
fully closed),
-the knob on the control panel (diaphragm machines only) is not on
zero.
5.2. The water flow does not stop:
-close the water cock, then remove the solenoid valve and thoroughly
clean the inside, including the closure spring housing, -open the cock
again and check it works,
-replace the valve if necessary.
5.3. The suction motor does not start:
-reset by using the key switch to turn the appliance off then on again,
-clean the collection tank around the sensor electrodes and the
electrodes themselves.
ATTENTION!
Do not move the electrodes from their original position. Make sure
they are not already out of position. By modifying the distance
between them, or between the electrodes and the side of the tank, the
power cut-off mechanism may be activated by mistake. Contact the

16 ENGLISH
Gansow Distributor Technical Assistance Service if necessary.
-check the main fuse.
-check the charge of the batteries and if necessary, charge.
5.4. Water is not sucked up, although the motor is operating;
-make sure the cap is correctly in place on the drain hose.
-make sure the suction hose between the squeegee and the dirty water
tank is not blocked. If necessary unblock and fix the hose well to both
connecting pieces.
-make sure the top lid is correctly in place on the tank, raise and lower
as described in point 3.3,
-check the batteries are not flat.
5.5. The squeegee leaves wet marks or stripes:
-clean the blades of the squeegee and remove any trapped grit or
paper,
-check the wear of the squeegee blades and if necessary, turn or
replace,
-PARABOLIC SQUEEGEE: make sure that when moving forwards with
suction on, the squeegee is perfectly horizontal. If necessary, adjust
the central nuts.
-carry out the checks described in point 5.4.
IMPORTANT!
When dealing with large amounts of fluff, this may accumulate under
the rear squeegee blade causing leakage and therefore preventing
perfect drying. If this occurs, the squeegee should be raised while at
the same time moving the machine backwards to pick up the dirt left
on the ground, proceeding in a diagonal direction.
5.6. The squeegee sticks to the floor due to strong suction:
-check the state of the front blade and in particular the inlet slits. If
obstructed or worn, clean or enlarge them slightly, or cut one to three
additional slits until the squeegee functions correctly,

ENGLISH 17
-turn round or replace excessively worn squeegee blades. They can be
reversed to extend the working life,
-STRAIGHT SQUEEGEE: adjust pressure on the ground using the
screw on the mobile support, tightening lightens the pressure,
unscrewing increases pressure.
-PARABOLIC SQUEEGEE: adjust pressure on the ground by
tightening the adjustment nuts above the levelling wheels on the back
of the squeegee.
5.7. The brush motor shuts down:
-the automatic battery protection device has tripped. Stop working and
recharge the batteries immediately.
5.8. The dirty water does not drain out through the hose:
-make sure the tank is not blocked near the drain outlet.
-remove any blockages in the drain hose itself.
5.9. The machine leaves a smeary mark:
-no water flow,
-no solution in the tank (fill the tank), or solution tank filter dirty (clean
filter),
-check the brush feed pipe which could be blocked, -open the
water cock if closed.
-carry out the additional checks described in point 5.1.
5.10. The machine does not move forward or moves forward too
slowly (BF SERIES MODELS WITH DRIVE ONLY)
-check and remove any oxidation on the battery terminals, then tighten,
-the squeegee is stuck to the ground by excessive suction. See point
5.6.
-the batteries are flat, stop work and recharge.

18 ENGLISH
6. SERVICE AND MAINTENANCE:
6.1. Before any servicing or maintenance work is carried out on the
machine and before any parts are replaced:
-drain both tanks completely,
-unplug the plug from the charger from the charger socket,
-turn off the key switch.
6.2. The electrodes in the dirty water tank should always be kept
clean and in their original position. By modifying the distance
between them, or between the electrodes and the tank, the
power cut-off mechanism may not activate correctly.
6.3. Clean the dirty water tank thoroughly and regularly to prevent
the formation of unpleasant odours and bacteria. Tilt the tank to
facilitate cleaning.
6.4. The tank lid should always be left open between cleaning
sessions to enable the internal surface to dry out. Never place
heavy objects on the top lid as this could warp it.
6.5. After each cleaning session, clean the outside of the machine to
remove any chemical residues which could accelerate wear and
affect the appearance of the materials.
6.6. The filter in the clean water tank should be cleaned regularly
twice a week.
6.7. Check the state of the squeegee blades regularly and if
necessary turn them over or replace them. See also sections
5.5.
and 5.6.

ENGLISH 19
6.8. Perform battery maintenance regularly to maintain their
efficiency and extend their working life. They are expensive and
should be kept in good condition.
6.9. The outlet slits on the suction motor should be checked and
cleaned regularly, especially where there is a considerable
amount of fluff in the atmosphere.
6.10. A general control by authorised Gansow personnel is
recommended at least once every six months.
7. OPTIONAL ACCESSORIES:
7.1. Depending on the type of floor and dirt, you may want to use
brushes other than those supplied as standard.
The following are available from your Gansow Distributor:
- Black soft and PES brushes for delicate floors (gyms, sealed wood,
etc);
- in polycarbonate of various hardnesses for a more energetic and deep
treatment.
7.2. As an alternative to the brushes, you can use a pad, available
in three versions with different colours:
- black = abrasive
- red/green/purple = medium hard
- brown/yellow/white = soft.
The brush does not need to be removed to use the pad, which can be
fitted directly to the brush itself. Alternatively, a special pad holder can
be provided.
