two stud bolts (1) placed on the upper part of the
squeegee, inside the slots on the support. Block
the squeegee by rotating the lever (2) clockwise.
Insert the squeegee hose (3) into its coupling, respecting its position as indicated in the figure.
ADJUSTMENT OF THE SQUEEGEE HEIGHT
The squeegee must be adjusted in height depending on the rubber we ar. In o rder to guarantee a perfect drying during the operation, the
lower blade of the rear squeegee rubber (4) must
work slightly bent backwards (operator side) in
uniformed way in all its length.
Acting clockwise upon the two registers (5) it is
possible to increase the bending of the rubber.
Acting counterclockwise it is possible to decrease the rubber bending.
A label placed near the two registers (5) indicates
rotation sense to increase or reduce the height.
Note: The wheels of the squeegee support must
be adjusted through the registers (5) at th e same
height so that the squeegee works parallel to the
floor.
ADJUSTMENT OF THE SQUEEGEE INCLINATION
In case of need, to increase the rubber bending
in the central part, it is necessary to tilt the
squeegee body rotating counterclockwise the
register (6). To increase the rubber bending on
the squeegee extremities, rota te the register
clockwise.
SPLASH GUARD ASSEMBLY
The two splash guards have to be assembled
onto the brushes base group. Insert the metal
strips inside the suitable slots present on the
rubber. Place the round hol e at the flat extremity
of the strip onto the screw placed in the front
part of the brushes base group. Secure the strips
through the nut blocking it.
Hook the spring in the rear part of the brushes
base group to the slot place d at the extremity of
the metal strip still free. Please act as above for
both the splash guard rubbers, paying attention
to reduce to the minimum the gap between the
two rubbers in the front part o f the brushes base
group.
With brushes assembled, the splash guard must
slightly touch the floor.
MANUAL ASSEMBLY OF THE BRUSHES

RECOMMENDED BRUSHES
Brushes must be chosen depending on type of floor and dirt to be removed.
The employed material and the bristles diameter are the ele ments that distinguish different types of brushes.
MATERIAL CHARACTERISTICS
PPL (Polypropylene) Good wear resistance. Maintains characteristics with hot water up to 60°C. It is not hygroscopic.
NYLON
Excellent wear resistance, even with hot water over 60°C. It is hygrosco pic. It looses its physical characteristics over the
time.
TYNEX Nylon bristles with grains of abrasive material. Use with caution in order not to mark the floor or ruin the polishing.
BRISTLES THICKNESS
Thicker bristles are more rigid and must be used on smooth floor o r floor with small joints.
On irregular floors with deep joints or relieves, it is recommended to use softer bristles which penetrate more easily and
deeper. Please be aware that when brushes bristles ar e worn out an d therefore too small, they become rigid and unable
to penetrate and clean deeper. This ma y also happen with thicker bristl es creating brush vibration.
PAD HOLDER
Pad holder is recommended to clean smooth surfaces. It has ancho r points which permit the blocking of the abrasive pad
during work.
