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 have been received and moreover to find out that the machine has not suffered damage during transportation. If damage has occurred, get the shipping agent to verify immediately the amount and nature of the damage suffered and at the same time inform our claim department. It is only by prompt action of this type that compensation for damage may be successfully claimed.

Introductory comment

This is a floor cleaning machine which, using the mechanic abrasive action of two rotary brushes and the chemical action of a solution water-detergent, is able to clean any type of floor, picking up during its advance movement, the removed dirt and the detergent solution which has not been absorbed from the floor. The machine must be used only for such purpose. We would impress upon you that any machine will function efficiently and operate successfully, only if used correctly and maintained in fully efficient working order. We therefore suggest you to read this instruction booklet carefully and re-read it whenever difficulties arise in the course of machine use. Our Service Department is at your disposal for all such advice and servicing as may prove necessary.

The coupling connector of the battery charger is delivered in the bag where this instruction booklet is found and must be assembled on the battery charger cables following the suitable instructions (see instruction booklet of the battery recharger).

6. RECHARGE OF THE BATTERIES

In order not to cause the risk of permanent damage to the batteries, one should at all costs avoid their complete discharge and effect recharging within a few minutes after that the signal lamp of discharged batteries begins to blink. NOTE: Never leave the batteries completely discharged, even if the machine is not being used. When recharging the batteries, keep the base support of the seat lifted. Every 20 recharging operations, check the level of the electrolyte and, if necessary, top up with distilled water.

WARNING! For the daily recharge of the batteries, it is necessary to follow strictly all the indications given from the constructor or from his dealer. Specialized staff must carry out all the installation and maintenance operations. Danger of gas

exhalations and emission of corrosive liquids. Fire danger: do not a

roach with free flames.

7. LEVEL INDICATOR FOR THE CHARGE OF THE BATTERIES

The batteries’ indicator is digital with 4 fixed positions and a blinking one. The numbers which appear on the display show the approximate charge level.

4 = maximum charge, 3 = charge 3/4, 2 = charge 2/4, 1 = charge 1/4, 0 = (blinking) discharged batteries

WARNING! Some seconds after that “0” blinks, the brushes

motor automatically switches off. Anyway, the machine can finish to dry before recharging the batteries.

MACHINE PREPARATION

8. SQUEEGEE

The squeegee, which is packed separately from the machine, should be assembled as shown in the figure, couple the stud bolts (1 - C85B) or the nuts (C100B) of the squeegee into their seats on the squeegee support and fix them with a key CH17. Fit the suction hose (2) into its coupling and fix it with the appropriate clamp.

During working operation, the rear rubber has to work slightly tilted backwards and this equally in its whole length for about 5 mm.

If it is necessary to increase the rubber bending in the central part, tilt the squeegee body backwards, loosen the adjuster nut (1) and rotate the knob (2) counterclockwise. If the rubber bending is to be noticeable at the sides of the squeegee, loosen the adjuster nut (1) and rotate the knob (2) clockwise. After regulations have been done fix the adjuster nut.

9. ADJUSTMENT HEIGHT SQUEEGEE SUPPORT

The squeegee has to be regulated in height depending on the wearing of the rubbers. To adjust this:

Loosen the ring nut (1)

With a key CH17 rotate the castor wheel through the nut (2) clockwise to lift the

squeegee and counterclockwise to lower it

Fix the ring nut (1)

NOTE: The right and left castor wheels have to be regulated equally.

MACHINE PREPARATION

10. BRUSHES ASSEMBLY

Connect the battery connector

Turn the key into position ON

With the manipulator lift the brushes base

Turn the key into position OFF and take it off from the instrument board

(to carry out the operations of brushes assembly with connected current can cause damage to the hands).

5. With the brushes base in lifted position, insert the brushes into the seat of the plate under the base until the three buttons fit into the holes of the plate. Turn the brush so that the buttons are pushed towards their retaining springs until the brush is clamped in place. The figure shows the direction of rotation for the coupling of the right brush. The left brush has to be rotated inversely.

WARNING! During this operation make sure that, there are not any objects or persons close to the brush.

6. It is recommended to invert daily the position of the right brush with the left one and vice versa. If the brushes are not new and they show deformed bristles, it is better to reassemble them in the same position (the right to the right side and the left to the left side), to avoid that the different inclination of the bristles causes an overload to the brushes motor and excessive vibrations.

MACHINE PREPARATION

11. SOLUTION WATER

Fill the solution tank with clean water at a temperature not more than 50

° C and add

liquid detergent in the proper concentration following the instructions of the manufacturer. Excess foam in the recovery tank could damage the suction motor, so use only the minimum amount of detergent necessary. Reassemble de cover.

WARNING! Always use low foam detergent. To avoid the production of foam, before starting to clean, put a minimum quantity of antifoam liquid into the recovery tank. Never use pure acid.

12. RECOVERY TANK

PERFORMANCE

13. Push forward the brushes manipulator (1) so to lower the base. During the descent, the signal lamps of the actuator and the brushes motor come on. The brushes base will be in its working position when the yellow signal lamp (2) comes off.

14. Press the accelerator pedal. The machine begins to move, the squeegee begins to lower itself and the suction motor comes on. During the first metres of operating, check that the brushes pressure is suitable (see further on under “BRUSHES PRESSURE”), that the quantity of the detergent solution is sufficient and that the squeegee dries perfectly. The machine will now start working efficiently until the detergent solution runs out.

Immediately disconnect the emergency lever (1) situated on the left side from the operator and apply the emergency brake (2), whenever the machine develops operating problems when it is working. These commands disconnect all the functions

on the machine. To start the machine again, once the problem has been solved, turn off the key (3), reconnect the connector (1), switch on the key (3) and lower the parking brake lever (2).

The machine will not start if the operator is not properly seated. When the solution tank is empty, the signal lamp on the instrument board comes on. When the recovery tank is full, the suction motor stops. To start it up again, even if the tank has been emptied, it is necessary to first turn off the main switch key and then on again.

PERFORMANCE

CHECK BRUSHES MOTOR

The brushes motor is electronically controlled. If it reaches pre-set overload limits, the red signal lamp (1) on the instrument board starts to blink. After a few seconds the motor stops and the signal lamp of the brushes switch goes off. To start up the motor again, turn the main switch key (2) off and on again. If the motor stops again, check the reason of the overload to prevent motor damage. Generally, it is enough to reduce the brushes pressure rotating the hand wheel (4) counterclockwise.

BRUSHES PRESSURE

It is possible to adjust the brushes pressure using the hand wheel (1) placed on the left side of the operator. To increase the pressure rotate clockwise. The pressure gauge (2) moves up as pressure increases. The pressure must be chosen based on the type of floor and the type of dirt. Excessive pressure causes higher brushes wear and a major energy consumption (for further information read on “CHOICE AND USE OF BRUSHES”)

TRACTION

Make sure that there is water in the solution tank (signal lamp “RESERVE” off)

4. Clean the solution filter

THE MACHINE DOES NOT CLEAN SATISFACTORILY

Check the condition of the brushes and replace them, if necessary (the brushes have

to be replaced when the bristles reach around 15 mm)

Check that the brushes pressure is sufficient, eventually increase it (see “BRUSHES

PRESSURE” under “PERFORMANCE”)

Use a different kind of brushes to the ones fitted as standard. For cleaning

operations on floors where the dirt proves to be particularly resistant, we recommend using special brushes which may be supplied optionally according to needs (see under “CHOICE AND USE OF BRUSHES”).

THE SQUEEGEE DOES NOT DRY PERFECTLY

Check that the squeegee is clean

Adjust the height of the squeegee support (see under “MACHINE PREPARATION”)

Clean the whole suction group (see under “WEEKLY MAINTENANCE”)

Replace the rubbers, if worn

TROUBLE SHOOTING GUIDE

THE SUCTION MOTOR DOES NOT FUNCTION

Check that the suction motor switch is on

Check whether the recovery tank is full and eventually empty it

3. Check the perfect condition of the float switch (see also “CLEANING OF THE RECOVERY TANK FILTER” under “DAILY MAINTENANCE”)

To reactivate the suction motor, after the intervention of the float switch, switch off

and then on again the main switch key

THE MACHINE DOES NOT START

The operator must be properly seated in the driving position

Check that the hand brake lever is completely released

Check that the general switch key is on

Check that the connector is connected to the batteries

EXCESSIVE FOAM PRODUCTION

Check that a low foam detergent has been used. If required, add a small quantity of antifoam liquid into the recovery tank. Remember that, when the floor is not very dirty, more foam is generated. In this case dilute more the detergent.

CHOICE AND USE OF BRUSHES

POLYPROPYLENE BRUSH (PPL)

It is used on all types of floors which are hot water resistant (not more than 60

°C). The Polypropylene brush is nonhygroscopic

and therefore conserves its characteristics even if working in the wet conditions.

NYLON BRUSH

It is used on all types of floors with excellent wear and hot water resistance (more than 60

°C). The nylon is hygroscopic and so,

over time, looses its characteristics working on the wet.

ABRASIVE BRUSH

The brush bristles are charged with very aggressive abrasives. It is used to clean very dirty floors. To avoid floor damages, work strictly only with the necessary pressure.

STEEL BRUSH

The bristles are made of steel wires; it is used to descale floors which are anyhow resistant to the abrasion, very uneven or with wide joints.

THICKNESS OF THE BRISTLES

The thicker the bristles are, the more rigid they will be. These ones are therefore used on smooth floors or with small joints. On uneven floors with deep joints it is recommended that, softer bristles, which enter more easily in depth, are used.

Please bear in mind that, when the bristles are worn out and get too short, they will get rigid and cannot penetrate anymore. As well as for thick bristles, the brush will begin to jump.

PAD HOLDER

The pad holder is recommended to clean glossy areas. There are two types of pad holders:

The traditional pad holder is equipped with anchor points which allow the abrasive pad to be held and dragged during the work

process.

The pad holder is of the CENTER LOCK type, apart from the anchor points, is equipped with a central blocking release system

made in plastic. This allows a perfect match with the abrasive pad and to hold it without the risk of falling down. This type of pad holder is recommended especially for machines with more brushes, where the centering of the pads is difficult.

For the power supply of the machine, use the following battery types:

• either lead batteries for traction use with tubular plates at free electrolyte;

• or sealed batteries for traction at recombination of gas with gel technology.

DO NOT USE OTHER TYPES OF BATTERIES.

Every battery is made of elements type DIN connected in series and assembled in two boxes each, each box supplies a power of 18V to the terminals. The maximum dimensions and the weight of each box are: C 85: width 500mm, length 350mm, height 505mm; weight 210kg C100: width 590mm, length 420mm, height 435mm; weight 250kg

They have to be moved by means of appropriate lifting and transport equipment suitable for their weight and dimensions. The batteries have to be hooked to the four holes present in the upper part of each box. They have to be inserted into the battery compartment with the battery terminals as shown in the drawing. They have to be connected in series, in order to obtain a voltage of 36V at the battery terminals. The electric connection process has to be carried out by specialised staff trained by a Comac service center.
