specting its position as indicated in the figure.
ADJUSTMENT OF THE SQUEEGEE HEIGHT
The squeegee must be adjusted in height depending
on the rubber wear. In order 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 pos-
sible 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 ro-
tation sense to increase or reduce the height.
Note: The wheels of the squeegee support must be
adjusted through the registers (5) at the same height
so that the squeegee works parallel to the floor.
ADJUSTMENT OF THE SQUEEGEE INCLINATION

2. Check the level of the liquid in the solution tank.
3. Check that solution filter (1) is clean.
4. The machine is equipped with solenoid valve,
therefore act upon the levers forward movement (7).
If the problem persists, please contact the authorized
technical assistance.
THE MACHINE DOES NOT CLEAN PROPERLY
1. The brushes do not have the suitable bristle di-
mension: use only original brushes. For advice, con-
tact the authorized technical assistance.
2. The brushes have got worn bristles. Check the
brushes wear condition and eventually replace them.
To replace the brushes, see instructions at paragraph
“BRUSHES DISASSEMBLY” and “BRUSHES ASSEMBLY”.
3. The solution detergent is insufficient: open more
the solution valve.
4. Check that the liquid detergent is in the recom-
mended percentage.
Contact the authorized technical assistance for ad-
vice.
THE SQUEEGEE DOES NOT DRY PERFECTLY
1. Check that the squeegee rubbers are clean.
2. Check the height and inclination of the squeegee
(see under “SQUEEGEE” in “BEFORE USE”).
3. Check that the suction hose is correctly inserted
in the proper seat on the recovery tank.
4. Clean the suction filter.
5. Replace the rubbers if worn out.
6. Check that the suction motor switch is on.
7. Check that the recovery tank is empty.
EXCESSIVE FOAM PRODUCTION
Check that low foam detergent has been used. Even-

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 elements 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 hygroscopic. It looses its physical characteristics over the time.
BRISTLES THICKNESS
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 brushes 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.
