On delivery of the machine
When the machine is delivered to the customer, an immediate check must
be performed to ensure all the material mentioned in the shipping
documents has been received, in addition to verifying that the machine
has not been damaged 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.
Introduction
MY 16 B 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
removed dirt 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 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.
Intended use
The 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) places.
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 in places with a potentially explosive atmosphere. In
addition, it is not suitable as a means of transport for people or objects.

5. 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 lifted (using the grips and suitable lifting devices) in order to remove it from the battery
compartment. DEAD BATTERIES ARE CLASSIFIED AS DANGEROUS WASTE AND MUST BE
DELIVERED TO THE AUTHORISED BODIES FOR CORRECT DISPOSAL.
6. INSERTING/CONNECTING THE BATTERIES
The machine is supplied with a built-in battery charger and an airtight gel battery. If you use batteries
other than those supplied with the machine, use only 12V 60Amp/h AGM or Gel batteries, and proceed
as follows:
1. The battery must be placed in the special compartment beneath the tank
2. Position the battery in the compartment, using the handle
3. Connect the clamps of the cable supplied as follows:
•red clamp on the positive pole (+) of the battery
•black clamp on the negative pole (-) of the battery
4. The battery must be secured with the appropriate safety strap.
5. Verify that the battery is correctly inserted and does not protrude from the compartment.
WARNING: you are advised to use airtight batteries only in order to avoid the
leakage of acids!
WARNING: you are advised to have the electric connections made by a
qualified, COMAC-trained technician
WARNING: you are advised to always wear protective gloves in order to avoid
the risk of serious injury to your hands.
WARNING: You are advised to only lift and move the batteries with lifting and
transportation means suitable for the specific weight and size

MACHINE PREPARATION
The solution tank has a maximum capacity of about 20 litres. Add the liquid detergent to the tank in the
concentration and manner indicated on the detergent manufacturer's label. The formation of excess
foam could damage the suction motor, so use only the minimum amount of detergent necessary.
WARNING: Always use detergents whose manufacturer's label indicates their
suitability for scrubbing machines. Do not use acid or alkaline products or
solvents without this indication.
In addition, you are advised to always use low foam detergents.
Do not use pure acids
Acid or alkaline detergents can be used with pH values between 4 and 10 and
that do not contain: oxidising agents, chlorine or bromine, formaldehyde,
mineral solvents.
WARNING: you are advised to always wear protective gloves in order to avoid
the risk of serious injury to your hands
17. DETERGENT SOLUTION ADJUSTMENT
Adjust the amount of solution through the tap lever on the front of the machine (1), pressing the main
switch of the machine the brush is activated and the machine starts moving. During the first few meters
check that the amount of solution is sufficient to wet the floor, but not excessive to exit the splash
guard. Bear in mind that the correct amount of solution is always depends on the nature of the floor, the
degree of dirt and the forward speed.
18. ASSEMBLING THE BRUSH
Proceed as follows to assemble the brush:
1. Raise the base by means of the appropriate pedal
2. Place the brush on the floor near the base body of the machine
3. With the base up, position the brush in line with the coupling on the machine.
4. Lower the base by means of the appropriate pedal
5. Press and instantly release main switch of the machine
WARNING! During this operation, ensure that there are no people or
objects near the brushes
WARNING: you are advised to always wear protective gloves in order to
avoid the risk of serious injury to your hands

2. OVERFLOW DEVICE
The machine is fitted with a ball filter which intervenes when the recovery tank is full, causing the suction
tube to close.
In this case, you must switch off the machine and empty the recovery tank.
WARNING: this operation must be carried out by wearing gloves in order to
protect against contact with dangerous solutions.
3. FORWARD MOVEMENTS
The traction of these machines is obtained by means of the brush which, working with the correct weight
distribution, is able to drag the machine forwards.
WARNING: when making even brief reverse movements, check the squeegee is
raised.
