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.
Intended use
The floor scrubbing machine is designed exclusively for the professional
cleaning of surfaces and floors in industrial, commercial and public
environments. The machine is only suitable for use in closed - or at least
covered - locations.
The machine is not suitable for use in the rain, or under water jets. It is
FORBIDDEN to use the machine for picking up dangerous dusts or
inflammable liquids within places with a potentially explosive atmosphere.
In addition, it is not suitable as a means of transport for people or objects.
Introductory comment
The MTECH 70 D is a floor scrubbing machine which, by means of the
mechanical action of the rotating brush and the chemical action of a
water/detergent solution, can clean any type of flooring. As it advances, it
also collects any removed dirt as well as 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 suggest you read this instruction booklet carefully
and read it again 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.

During the working of the machine, pay attention to other people and especially to children.
Only use the brushes supplied with the machine, or those specified in the "CHOOSING
AND USING BRUSHES" paragraph of the instruction manual. The use of other brushes
could compromise safety levels.
WARNING:
The machine is not suitable for use by children and persons with reduced physical, mental
and sensory capabilities, or people who lack experience and knowledge.
The machine must not be used or stored outdoors, in damp conditions or directly exposed
to rain.
The storage temperature must be between -25°C and +55°C, and the machine should only
be stored in an enclosed area.

WARNING: If batteries with weights or dimensions differing from those advised above
are used, the machine performance could vary considerably.

17
MACHINE PREPARATION
10. BATTERY MAINTENANCE AND DISPOSAL
For maintenance and recharging, respect the instructions provided by the battery manufacturer.
Particular attention must be paid when choosing the battery charger, if not supplied, since there are
different kinds according to the type and capacity of the battery.
When the battery reaches the end of its working life, it must be disconnected by expert, trained personnel
then removed from the battery compartment with the aid of suitable lifting devices. DEAD BATTERIES
A
RE CLASSIFIED AS DANGEROUS WASTE AND MUST BE DELIVERED TO THE AUTHORISED
BODIES FOR CORRECT DISPOSAL.
11. HANDLING - INSERTING BATTERIES
The batteries must be housed in the special compartment beneath the recovery tank and should be handled using
lifting equipment that is suitable in terms of both weight and coupling system. They must also satisfy the requirements
of Standard CEI 21-5. The dimensions of the battery compartment are: 353 mm x 333 mm x H250mm.
WARNING: Ensure that you comply with the accident prevention regulations in force
in the country where you work or with DIN EN 50272-3 and DIN EN 50110-1, before
any handling of the batteries.
WARNING: To prevent an accidental short circuit use insulated tools to connect the
batteries, and do not place or drop metal objects on the battery. Remove rings,
watches and any clothing with metal parts that may come into contact with the battery
terminals.
To insert the batteries into the compartment proceed as follows:
1. Check that the recovery tank is empty; if not, empty it using the tube provided for this purpose (01)
positioned at the rear of the machine.
2. Check that the main switch (02) is in the "0" position; if not turn the key a quarter turn to the left (for B-
BT version only), and remove the key from the instrument panel. Check that the machine's main switch
at the back of the machine is in the “0” position; if not, turn to “0” (for BB version only).
3. Make sure the electric system connector (03) is disconnected from the battery connector; if not,
disconnect it.
4. Rest the brush head on the floor.
5. Rest the squeegee on the floor, by moving the lever designed for this purpose, positioned on the rear
of the machine.
6. Secure the machine by applying the parking brake, move the lever (04) on the right side of the
machine (only for BT versions).
7. Remove the recovery tank drainage tube (01) and lay on the ground.
8. Remove the vacuum motor tube (05) from the connector present on the recovery tank.
9. Remove the squeegee vacuum hose (06) from the hole in the recovery tank.

18
MACHINE PREPARATION
10.Remove the vacuum cover and attach to the support designed for this purpose, positioned at the rear
of the machine.
11.Remove the recovery tank from the machine, taking care with the drainage hose, and rest on a raised
surface in order to avoid accidental damage.
WARNING: The shape of the recovery tanks means that it can be rested on the
ground with the rear part in contact with the floor, in order to avoid accidental damage
to the drainage joint.
12.Using the correct tool, attach the battery locking blades (07) to the flat base of the batteries.
In the image to the side, the position of the blades for 12V 77Ah batteries is shown (battery size: 259
mm x 168 mm x H208mm each with a weight of 27 kg).
In the image to the side, the position of the blades for 12V 75Ah batteries is shown (battery size: 259
mm x 168 mm x H208mm each with a weight of 25 kg).
WARNING: Before installing the battery, clean the battery compartment with a damp
cloth. Check that the connectors on the cables supplied are functioning correctly.
WARNING: Check that the characteristics of the battery that you are looking to use
are appropriate for the type of work to be performed. Check the battery charge and
the condition of the contacts on the battery.
WARNING: You are advised to only lift and move the batteries with lifting and
transportation means suitable for the specific weight and size
WARNING: The lifting hooks must not damage the blocks, connectors or cables.
13.Place the batteries in the correct compartments, positioning the “+” and “-“ poles opposite each other,
taking care not to table the vacuum motor tube (05).
In the image to the side, the position of the battery blades is shown for 12V 77Ah batteries.
WARNING: Before inserting the batteries into the machine, remember to cover the
terminals with a little grease to protect them against external corrosion.
In the image to the side, the position of 12V 75Ah batteries is shown. Place the batteries into the correct
compartment, positioning the "+" and "-" poles opposite each other as shown in the diagram, taking care
not to damage the vacuum motor tube (05).
WARNING: Before inserting the batteries into the machine, remember to cover the
terminals with a little grease to protect them against external corrosion.

13. CONNECTING THE BATTERY CHARGER (VERSIONS WITHOUT BC)
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.
WARNING: Never leave the batteries completely discharged, even if the machine is
not being used. Check the battery charger is suitable for the batteries installed, in
terms of both capacity and type.
To connect the battery charger you must:

2. Check that the recovery tank is empty; if not, empty it using the tube provided for this purpose (01)
positioned at the rear of the machine.
3. Check that the main switch (02) is in the "0" position; if not turn the key a quarter turn to the left (for B-
BT version only), and remove the key from the instrument panel. Check that the machine's main switch
at the back of the machine is in the “0” position; if not, turn to “0” (for BB version only).
4. Make sure the electric system connector (03) is disconnected from the battery connector; if not,
disconnect it.
5. Rest the brush head on the floor.
6. Secure the machine by applying the parking brake, move the lever (04) on the right side of the
