On consignment of the machine
When the machine is consigned to the customer, an immediate check must be
performed to ensure all the material mentioned in the shipping documents has
been received, and also to check the machine has not suffered damage during
transportation. If this is the case, the carrier must ascertain the extent of the
damage at once, informing our customer service office. It is only by prompt action
of this type that the missing material can be obtained, and compensation for
damage successfully claimed.
Introductory comment
This is a floor scrubber-dryer which, via the abrasive mechanical action of the two
rotating brushes and the chemical action of a water/detergent solution, can clean
any type of flooring. As it advances, it also collects the dirt removed and the
detergent solution not absorbed by the floor.
The machine must only be used for this purpose. Even the best machines will
only work well if used correctly and kept in good working order. We therefore
recommend you read this instruction booklet carefully, and consult it whenever
difficulties arise while using the machine. If necessary, remember that our
customer assistance service (organised in collaboration with our dealers) is
always available for advice or direct intervention.

MACHINE PREPARATION
TYPE OF BATTERY
To power the machine you can use:
•two lead traction batteries with tubular plates and free electrolyte;
•two airtight traction batteries with gas recombination gel technology.
Each battery consists of elements connected in series so as to provide the clamps with a voltage of
24V.
The maximum dimensions of each battery are:
-width: 195mm, length: 360mm, height: 250mm
The maximum weight of each of the two batteries is 20kg.
To obtain a voltage of 24V, they must be connected together in series by specialised personnel
trained at the Comac Technical Assistance Centre
FITTING THE BATTERIES INTO THE MACHINE
The batteries must be housed in the special compartment beneath the recovery tank. They should be
handled using lifting equipment that is suitable in terms of both weight and hook-up system.
They must also satisfy the requirements of Standard CEI 21-5.
To insert the batteries you must:
Open the recovery tank cover, bringing it forwards.
detach the squeegee tube (1) from the recovery tank.
unthread the suction cap (2) by rotating it anticlockwise.
detach the “recovery tank” drainage tube from its hook.
remove the recovery tank.
21
Position the batteries.
Connect the battery connector (2) to the machine connector (1).
Reassemble all the elements
WARNING! all installation and maintenance operations must be carried out by
specialized personnel.

MACHINE PREPARATION
RECHARGING THE BATTERIES
Check the battery charger is suitable for the batteries installed, in terms of both capacity and type
(lead/acid or GEL and equivalents).
ATTENTION: Never recharge GEL batteries with an unsuitable battery charger. Follow
the instructions given by the battery/battery charger manufacturer with the utmost
attention.
In order not to cause permanent damage to the batteries, it is essential to avoid their
complete discharge: arrange the recharge within a few minutes of the switching on of
the "discharged batteries" blinking light.
NOTES: Never leave the batteries completely flat, even if the machine is not being
used.
WARNING! For the daily recharging of the batteries, you must fully respect the
indications provided by the manufacturer or retailer. all installation and maintenance
operations must be carried out by specialized personnel. Danger of gas exhalation
and leakage of corrosive liquids. Danger of fire: Keep naked flames at a safe
distance.
BATTERY INDICATOR
The battery indicator is digital, with 4 fixed positions and a flashing one. The numbers that appear on
the display show the approximate charge level.
4= maximum charge, 3= 3/4 charge, 2= 2/4 charge, 1= 1/4 charge,
0= discharged batteries (flashing)
WARNING! A few seconds after the appearance of the flashing “0”, the brush motor
switches off automatically. With the remaining charge it is possible to complete the
drying process before starting the recharge.
ASSEMBLING THE SQUEEGEE
For packaging reasons, the squeegee is supplied disassembled from the machine, and must be
assembled as shown in the figure, inserting the clip into the small column of the squeegee.
Insert the squeegee tube in the special sleeve.

10
MACHINE PREPARATION
ADJUSTING THE SQUEEGEE HEIGHT
The height of the squeegee must be adjusted on the basis of the state of wear and tear of the rubber
blades. To do this, turn the wing nuts (1) anticlockwise to raise the squeegee, and clockwise to lower
it.
Remarks: the right and left wheels must be adjusted to the same level, so the squeegee can work
parallel to the floor.
1
ADJUSTING THE SQUEEGEE INCLINATION
During working operation, the rear rubber blade is slightly tilted backwards (by about 5mm) in a
uniform way for its whole length. If it is necessary to increase the bend of the rubber in the central
part, you must tilt the squeegee backwards, rotating the adjuster (1) anticlockwise. To increase the
bend of the rubber at the sides of the squeegee, rotate the adjuster clockwise. When fully adjusted, fix
the lock nut.
5mm
RECOVERY TANK
Open the cover and check the suction cap (2) is correctly blocked (insert the notches in their
housings, rotating the cap clockwise) and correctly connected to the tube leading to the suction
motor.
In addition, check the squeegee tube (1) is correctly inserted in its housing, and that the drainage tube
cap (in the rear part of the machine) is closed.
12
DETERGENT SOLUTION
Fill the solution tank with clean water at a temperature no greater than 50C and add liquid detergent
in the proper concentration, following the instructions of the manufacturer. The formation of excess
foam could damage the suction motor, so use only the minimum amount of detergent necessary.
Reassemble the cap.
WARNING! always use low-foam detergent. To avoid the production of foam, put a
minimum quantity of antifoam liquid in the recovery tank before starting to clean.
Do not use pure acids.

11
MACHINE PREPARATION
ASSEMBLING THE SPLASH GUARD
For packaging reasons, the splash guard is supplied disassembled from the machine, and must be
assembled as shown in the figure.
ASSEMBLING THE BRUSHES ABILA 42-52
Raise the base by means of the appropriate pedal.
With the base up, insert the brushes in the plate housing beneath the base, turning them until the
three pins enter the niches in the plate itself; turn until the pin is pushed towards the coupling
spring and is locked into place:
the figure shows the rotation direction to hook up the right-hand brush; for the left-hand one,
rotate in the opposite direction.
you are advised to invert the right and left-hand brushes every day. If the brushes are not new
however, and have deformed bristles, it is better to reassemble them in the same position (the right-
hand one on the right, and the left-hand one on the left), to prevent the different inclination of the
bristles producing an overload on the brush motor as well as excessive vibrations.

12
MACHINE PREPARATION
ASSEMBLING THE BRUSH ABILA 17-20
1. Raise the base by means of the appropriate pedal.
2. With the brush head up, position the brush in line with the coupling on the machine.

19
TROUBLESHOOTING
INSUFFICIENT WATER ON THE BRUSHES
Check that the tap (1) is turned on.
Check there is water in the solution tank.
1
THE MACHINE DOES NOT CLEAN WELL
Check the state of wear and tear of the brushes and, if necessary, replace them (the brushes must be
replaced when the bristles are about 15mm long).
To replace the brushes, see “DISASSEMBLING THE BRUSHES” and “ASSEMBLING THE BRUSHES”.
Use a different kind of brush to the one fitted as standard. For cleaning floors where the dirt is
particularly resistant, we recommend the use of special brushes supplied upon request and according
to needs (see “CHOOSING AND USING THE BRUSHES”).
THE SQUEEGEE DOES NOT DRY PERFECTLY
Verify that the squeegee rubbers are clean
Adjust the inclination of the squeegee (see "SQUEEGEE" under “MACHINE PREPARATION”)
Check the suction tube is correctly inserted in its housing on the recovery tank
Disassemble the entire suction unit and clean it
Replace the rubbers, if worn
Check the suction motor switch is turned on
Check wheel adjustment
EXCESSIVE FOAM PRODUCTION
Check that a low foam detergent has been used. If necessary, add a small quantity of anti-foam liquid
to the recovery tank.
Remember that, when the floor is not very dirty, more foam is generated. In this case the detergent
solution should be more diluted.

20
CHOOSING AND USING THE BRUSHES
POLYPROPYLENE BRUSH (PPL)
Used on all types of floors. Good resistance to wear and tear, and hot water (no greater than 60°C.). PPL is non-hygroscopic and therefore retains its
characteristics even when working in wet conditions.
NYLON BRUSH
Used on all types of floors. Excellent resistance to wear and tear, and hot water (even over 60°C). The nylon is hygroscopic and so tends to lose its
characteristics over time when working in wet conditions.
ABRASIVE BRUSH
The bristles of this type of brush are charged with highly aggressive abrasives. It is used to clean very dirty floors. To avoid floor damage, work only
with the pressure strictly necessary.
BRISTLE THICKNESS
Thicker bristles are more rigid and are therefore used on smooth floors or floors with small joints.
On uneven floors or those with deep joints, it is advisable to use softer bristles which can enter the gaps more easily.
Remember that when the bristles are worn and therefore too short, they will become rigid and are no longer able to penetrate and clean deep down.
In this case, like with over-large bristles, the brush tends to jump.
PAD HOLDER
The pad holder is recommended for cleaning shiny surfaces.
There are two types of pad holder:
1. The traditional pad holder is fitted with a series of anchor points that allow the abrasive floor pad to be held and dragged while working.
2. The CENTRE LOCK type pad-holder not only has anchor points, but also a snap-type central locking system in plastic that allows the abrasive
disc to be perfectly centred and held without any risk of it becoming detached. This type of holder is especially suitable for machines with
several brushes, where it is difficult to centre the abrasive discs.
