Technical Information
General description
This machine is a scrubber dryer for washing and drying at, horizontal, smooth or moderately rough, even and obstacle free
oors in civil and industrial premises.
The scrubber dryer spreads a solution of water and detergent in the correct concentration on the oor and then scrubs it to
remove the dirt. By carefully choosing the detergent and brushes (or abrasive disks) from the wide range of accessories available,
the machine can be adapted to a wide range of combinations of types of oor and dirt.
A suction system incorporated in the machine dries the oor after washing by means of the low pressure generated in the dirty
water tank by the suction motor. The squeegee connected to the tank collects the dirty water.
Key
The main parts of the machine are as follows:
• The tank (Fig.1-ref.1), contains and carries the mixture of clean water and cleaning product and collects the dirty water
picked up from the oor after washing.
• Control panel (Fig. 1-ref. 2).
• Head assembly (Fig. 1-ref. 3): the main element comprises the brushes/rollers which distribute the detergent solution
onto the oor and remove the dirt.
• Squeegee assembly (Fig. 1-ref. 4): wipes and dries the oor by collecting the water.
Hazard areas
• Control panel: risk of injury from short circuits.
• Tank assembly: when using certain detergents, danger of irritation for eyes, skin, mucous membranes and respiratory
tract and of asphyxia. Danger represented by the dirt collected from the environment (germs and chemical substances).

• Activate the drive lever, start working.
• If necessary, adjust the ow of detergent delivered to the brush; the outlet
ow must be metered in relation to the required travel speed; the slower
the machine travels, the less detergent must be delivered.
• Persist when washing particularly dirty points to give the detergent time
to perform its chemical action detaching
and suspending the dirt and the brushes time to exert an eective
mechanical action.
Drying:
• Select the Suction operating program, lower the squeegee.
• Activate the drive lever, start working.
• Pass over the same area washed previously. The result is equivalent to in-
depth washing and subsequent ordinary maintenance will take less time.
