results, the rear rubber of the
squeegee must be bent equally in
length. To adjust, it is necessary to
put the machine in operation and
therefore the vacuum motor has to be
switched on and the brushes have to
function together with the detergent
solution.
ATTENTION:
Every type of floor requires a
specific adjustment. For example,
concrete floors (where the friction
results will be high) need little
pressure, while smooth floors
(ceramics) need higher pressure.
If the cleaning operations are made
always on the same type of floor, the
adjustment can change only in
function of the rubber wear.
SPLASH GUARD ASSEMBLY
The two splash guards have to be
assembled onto the brushes base
group as indicated in the following
figures. Insert the metal strips inside
SQUEEGEE ASSEMBLY
1. Keep the squeegee support (1)
slightly lifted from the floor.
2. Insert the threaded parts of the two
bolts (4) sliding them inside the two
slots on the support placed on the
upper part of the squeegee (2).
3. Put the washers (3) into position,
there are two for each bolt, so that
they are assembled one under and
the other over each of the two slots
present on the support.
4. Secure the squeegee by rotating
the two levers (4) clockwise.
5. Insert the squeegee hose (5) into
its coupling, follow the picture for
positioning.
The lower part of the rubber is overly

RECOMMENDED BRUSHES
Brushes must be chosen depending on floor type and dirt to be removed.
The material and bristle diameter are the elements that distinguish different types of brushes.
MATERIAL CHARACTERISTICS
PPL (Polypropylene) Good wear resistance. Maintains characteristics with hot water up to 50°C. It is not hygroscopic.
NYLON Excellent wear resistance, even with hot water. It is hygroscopic.
TYNEX
BRISTLES
THICKNESS
PAD HOLDER
Nylon bristles with grains of abrasive material. Use with caution in order not to mark the floor or
ruin the polishing.
Thicker bristles are more rigid and must be used on smooth floor or 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 brush bristles are worn out and
therefore too small, they become rigid and unable to penetrate and clean deeper. This may also
happen with thicker bristles creating brush vibration.
It has anchor points which permit the blocking of the abrasive pad during work. The pad is
recommended to clean smooth floors.
