it cannot be used as a tractor, neither on ramps with slopes higher than 13%, nor to tran- sport people.

HANDLING OF PACKED MACHINE

The machine is supplied packed on pallet, closed in a box made of plywood or paper board. The weight and sizes are shown in the NORMAL CHARACTERISTICS. The bary- center position is indicated by a black arrow on the box. The forks of the lift truck or of the transpallet should be placed so that the black arrow indicated on the packing is about in the centre of the forks. The package should be handled with extreme caution, thus avoiding impacts or lifting it to remarkable heights without any reasons. It is forbidden to stack the packages one another.

fig. 1

UNPACKING THE MACHINE

The unpacking of the machine should be performed with caution and accuracy. First of all, cut the straps with proper cutting nippers, thus paying attention to the spring-back. Then, re- move the clips on the paper board base which bind the paper board to the pallet by using a screwdriver or a proper tool, and lift the paper board up. In case of package made of ply- wood, remove the clips on the sides and on the base of each panel as well. Now remove the other clips fastening the machine by cutting them in the same way of the external ones. At this point, the machine should be brought at ground level by means of a metallic or woo- den ramp.

HANDLING OF UNPACKED MACHINE

Check the unpacked machine and mount the batteries, if not yet installed. If the machine must be handled for a short transport after beeing used, detach the battery cables and re- move brushes and squeegee; for a longer transport, it is recommended to pack the machi- ne again in its original box. The machine can be thrust-moved for short distances.

USE OF THE MACHINE

CAUTION

SAFETY SYSTEM

WARNING: the machine is equipped with a safety system for “emergency stop”, constitued by a mushroom push-button (fig.). In emergency case, press down this button. Before lear- ning how to use the machine, the operator should be familiar with the use of this safety sy- stem, to automatically use it in case of emergency. Never reset the safety system before having solved the failure, if necessary with the help of a specialized technician.

fig. 5 fig. 6

BRAKE

The machine is provided with a parking and an emergency brake as well. The emergency brake is controlled by a pedal located on the left-hand side of the footboard (fig.). To enga- ge the emergency brake, press down the pedal and insert the block by means of the lever

(fig.) pressed downward. CAUTION: the brake should be checked and adjusted at least once every three months.

PREPARING THE MACHINE FOR OPERATION

Upon delivery of the machine, remove the packing without damaging it. It can be re-used for any possible long displacements of the machine. Check immediately the machine state, and in case of damages due to the transport, contact the trucking company to file a freight damage claim. Before starting the machine, read carefully the contents of this manual, in particular the safety standards.

INSTALLING THE BATTERIES

Install the batteries on the proper compartment. Inspect batteries carefully before installing, thus making sure that there are no cracks in the cases. Never add electrolyte if batteries have been in use for one week or longer. For positive connections of the batteries, the sur- faces which get in contact with them should be clean. Apply a film of grease of vaseline to terminal clamps or connections. During transit, the batteries may have lost some of their charge. If so, give a freshening charge before operating the machine.

INSTALLING THE BATTERY CHARGER

Install the battery charger in a ventilated and dry place, far from heat sources and corrosive environments. Make sure that the voltages are correct (see the data plate located on the battery charger). Protect the mains with a delayed switch or with a load fuse higher than the max. power consumption of the battery charger. Observe the polarity of the battery soc- ket (black cables are identified by symbols + and -).

CHOOSING THE DETERGENT SOLUTION

For a good cleaning of the floor, it is important to choose the proper detergent solution. If necessary, ask the supplier or a competent person for the proper solution. Keep in mind that a too strong chemical agent can compromise the long life of each machine. It is neces- sary to use a low-sudsing detergent solution, or an antifoaming additive, in order not to da- mage the vacuum motor. If it is impossible to get these products, use some vinegar to avoid foam, pouring 50cc of it in the recovery tank before scrubbing.

STARTING AND PREPARING THE MACHINE

If the scrubber is connected to the battery charger (having finished the charge operation), detach the battery charger plug from the socket (located on the machine) coming from the battery (fig.). Then, connect the plug of the machine to this latter (fig.). Close the battery co- ver again. The machine should be operated by turning the master key switch (fig.). Then, proceed with the water loading described under the paragraph (par.). Perform the scrub- bing once the work place has been reached.

SCRUBBING

The scrubbing operation is very delicate, as the operator’s experience must be used to deci- de upon the brush type, the requirement of a possible double scrubbing operation, the right cleanser choice and the right machine adjustments: if only one of these factors is inadequa- te, the scrubbing operation can give very poor results. If the floor is very dirty or difficult to be cleaned, a double scrubbing operation is recommended. In this first phase, the squee- gee must be lifted and the brushes must be in working position. Start the brushes and pass the machine over a surface of some tenth sq. mt. Let the detergent solution on the floor to dissolve the dirt, then pass the machine again. For this second machine passage, lower the brushes and bring the squeegee in contact with the floor. Look at the floor after this se- cond passage and decide if the scrubbing operation was enough or if an additional opera- tion is required. To perform the scrubbing procedure, turn the switch to pos. 2 (fig.) and keep it there till you hear the end-of-stroke croaking noise. The motor brushes will go auto- matically on and the brushes wil be in contact with the floor, with the right pressure too. Now operate tmmediately the lever to apply the detergent water, and adjust it accordingly. Put the run selector (fig.) in its forward position and press the pedal (fig.) so that the machi- ne moves forward and starts scrubbing. The water dosage must be adjusted to get the who- le suface completely wet after the brush passage, but without any excess, that could gene- rate splashes, stream or flows out of the squeegee. If no double scrubbing will be effected, lower the squeegee immediately after having put to forward the run selector. The squeegee is lowered through the switch set to pos. 1 (firm). The suction motors go automatically on during the squeegee lowering and go off when it is lifted back. At the end of the scrubbing and drying operation, close water through its lever (fig.), then set the switch (fig.) to pos. 1 till you hear the end-of-stroke noise, to lift the brushes. Finally, set the switch (fig.) to pos. 0 to lift the squeegee. Note that, during backwards motion, the squeegee is automatically lif- ted.

WATER FILLING AND DISCHARGE, TANK CLEANING

Before every scrubbing operation, open the door (fig.) and fill the solution tank with the right quantity of water and cleanser. The tank is made of polyethilene, resistant to all acid and basic solutions and to all dissolvents found on the market. At the end of the scrubbing operation, discharge the dirty water from the recovery tank by means of the hose (fig.). The recovery tank is made of polyethilene too. Accurately clean the recovery tank at least once per week.

SQUEEGEE ADJUSTMENT

The squeegee must be perfectly adjusted to get a perfect floor drying. ICM 38 is equipped with a V-shaped squeegee, as shown in (fig.). This type of squeegee performs very well in collecting water from the floor to the suction hose, but is particularly sensitive to the paralle- lism to the floor. Therefore, adjust first its angular position through the screws (fig.) so that its rubber blades get the same slanting on the floor along its entire width. If blades are more pressed at their ends than in their centers, unscrew the upper screws (fig.) and screw the lower ones (fig.), then tighten the lock nuts. If, on the contrary, blades are more pres- sed at their centers than in their ends, perform the opposite operation. After having rea- ched the right angular position, adjust the pressure. Turn the ring nut (fig.) and tighten it to increase pressure to the floor, or loosen to decrease it. The right pressure is got when the edge of the rear blade touches the floor with a slanting of approx. 60°-45° referring to the floor. If the pressure is too high, the rear blade will touch the floor with its side surface, and not with its edge. If the pressure is too low, the edge doesn’t work well and lets some water on the floor, particularly on an uneven floor. Of course the optimal adjustment is confirmed by very good results of the drying operation, and the operator’s experience will contribute to enhance such good results. Note that often drying is negatively affected by a wrong suc- tion operation. If the suction hose doesn’t work well, drying will continue to be bad, even with all adjustments attempts. In this case: a) accurately clean the suction hoses, their inlets and filters and the squeegee itself b) check the vacuum motors operation c) confirm that all inspection openings of the tank are closed.

BRUSHES REPLACEMENT

Before replacing the brushes, extract the key from the control dashboard, thus avoiding that any accidental ignition of some motors could cause damages. First of all remove the knobs (fig.) by unscrewing them, then extract the brush covering carter (fig.). Rotate each brush until its knob (fig.) can be reached, then extract it and remove the brush fallen on the ground. To insert the new brush, place the hexagon of the female joint (fig.) under the male joint located on the motor, then lift the brush vertically by rotating it until its automatic inser- tion has been reached. After placing the three brushes, insert the carter and screw the knobs again.

BATTERIES

CHECKING THE CHARGE STATE OF THE BATTERIES

As it is known that there is a direct relation between the specific gravity of the electrolyte and the charge state of the battery, the measure of the specific gravity of the electrolyte is assumed to be an efficient and correct control of the battery charge state. When the battery is charged and is under normal conditions, with the electrolyte located at the proper level, the electrolyte density will be about 1.260 (30°Bè) referred at 30°C. If density is between

1.26 (30° Bè) and 1.20 (24° Bè), the battery is partially discharged, but if density is lower than 1.14 (18° Bè), the battery is completely discharged.

DENSITY MEASUREMENT

The density measurement of the electrolyte is the most important check on a battery. This measure should be performed with extreme caution by means of a densimeter. The syringe densimeter should be introduced, thus extracting an amount of electrolyte enough to bring the float on the surface. The float top should neither get in touch with the rubber pear nor be stuck with capillarity to the glass walls. Should a density measure be performed after ha- ving added some distilled water, wait until the density has become homogeneous in all liq- uid contained in the element.

WATER TOPPING UP

Add some distilled water in each battery cell, after charging the batteries, to bring the liquid to a level of 6 mm over the plates. The operation will initially take place after each charge, then the subsequent toppings up can be executed less frequently, according to the expe- rience of the person responsible of it, but never let more than one week between one top- ping up and the next.

CHARGE LIMITS

Battery should not be recharged if density, at the end of a working day, has not gone under

1.24 (28° Bè). The most common abuse detected in the use of traction batteries is the over- charge. The overcharge, if continuously applied, can considerably shorten the battery life.

The max. recommended temperature is 45°C. If the electrolyte temperature increases by

10/12°C beyond the environment temperature, the overcharge can take place inde- pendently of the effective temperature reached.

ROOMS FOR BATTERY CHARGE

Gases generated during charge operation can be highly explosive; during charge operation, battery should be freely ventilated and the contacts to the terminals should be safe to avoid any possible sparks. The rooms in which the accumulator batteries are charged should be well-ventilated and the temperature should not be higher than 40/45°C. If windows do not provide a sufficient ventilation, install special discharge pipes that should not lead to the flues. When necessary, air exchange should be made in the fastest way by means of fans.

BATTERIES INACTIVE OR NOT IN CONTINUOUS OPERATION

During inactive periods, batteries are subject to a spontaneous discharge (auto-discharge).

The auto-discharge substracts every day from the battery a part of its charge and causes a sulphation of the plates, which increases in the long run, thus compromising the battery effi- ciency. If the battery is not continuosly used, perform a refresh charge at least once a month.

This procedure must be executed even if the measurements of the specific gravity supply high values.

If battery remains inactive for long periods of time, it should be stored in a dry and fresh pla- ce. Once a month, it should be charged with the current intensity indicated as “final”, until all elements denote a lively gas development and until all readings regarding the voltage and the specific gravity as well remain constant for 3-4 hours.

In any case, before re-operating a battery which is inactive for a long period of time, rechar- ge it and check for a correct level of the electrolyte.

DIAGNOSTIC MESSAGES OF MOSFET SPEED CONTROLLER

DIAGNOSTIC MESSAGES:

1 flashes

2 flashes a command is active at startup of equipment, usually this happens if a speed direction is already selected once the key is turned ON. In order to reset the diagnostic the command must be put to null position the battery is too low and the equipment is signalling the undervoltage status. The battery must be recharged the equipment doesn’ t operate correctly and the battery itself could be worn out or damaged

3 flashes this diagnostic message is not implemented

4 flashes the motor power circuit is not correctly closed. Check if there is a stray loss in the power cable to the motor or the speed controller. Check if the power fuse is interrupted

5 flashes equipment internal failure. Disconnect power to the speed controller

6 flashes potentiometer failure. Check if one or more wires to the potentiometer are disconnected or stray loosing

7 flashes

8 flashes reduced in order to manage the maximum temperature, the diagnostic is turned OFF when the temperature is below the over temperature diagnostic set point the speed controller has been tumed ON when the motor is already rotating. This happens usually when the machine is pushed or it is moving by inertia. The speed controller will ouput power only when the motor will be stoppe d

9 flashes softwere failure or incorrect operation. If this diagnostic is always present the speed t ll t b t t d b t i d t h i l l

SQUEEGEE BLADE REPLACEMENT

The squeegee blades should be replaced when the contact edge becomes worn; the per- fection of the edge is essential for a perfect drying. To replace the blades, the squeegee should be demounted from the machine. To do that, lift the squeegee support in UP posi- tion, then remove the suction pipe from the squeegee, partially unscrew the screws. At this point, remove the squeegee from the machine and place it on a desk. Now, remove the screws (fig.6) both on the front part and on the rear part of the squeegee, the steel straps

(fig.6), and the three worn rubber blades (fig.6) as well. Perform the inverse procedure and assemble the new blades, then adjust the squeegee.

VACUUM MOTOR MAINTENANCE

The vacuum motors must be checked and cleaned. The brushes should be checked all six months and replaced, if necessary. After removing the key from the dashboard, remove the motor cover located on the rear part of the machine. To release the motors, unhook the hooks and detach the plug. In this way, it is possible to extract the motors and release the sponge filter under the motors that can be extracted, cleaned and replaced. Check the suc- tion fan from the hole located in the front part of the vacuum motor. By a visual check, the fan should appear undamaged and well-cleaned. To check the brushes, first of all remove the plastic cap (fig.7), then unscrew the screws (fig.7) and remove the two plastic supports of the brushes. Once checked and replaced (if necessary), the brushes can be easily re- mounted, by reassemblying all elements until the initial situation has been reached.
