FOAM OVER-FORMATION
1.
Check if the low-foam detergent is used, if necessary add little anti-foam liquid to the recovery tank.
2.
Please remember that more foam is generated when the floor is clean, in this case use a more diluted detergent.
CHOICE AND USE OF BRUSHES
POLYPROPYLENE BRUSH
（
PPL
）
It is used on all floor types and offers good resistance to wear and to hot water (not over 60
℃
). PPL is not hygroscopic, and
then preserves its character even when working on wet floors.
NYLON BRUSH
It is used on all floor types and offers excellent resistance to wear and to hot water (not over 60
℃
). NYLON is hygroscopic
and tends, over a period of time, to loose its character when working on wet floors.
ABRASIVE BRUSH
This brush bristles are impregnated with highly aggressive abrasives. The brush is used to clean very dirty floors. We
recommend using only the minimum pressure to prevent damages to the floor.
BRISTLES THICKNESS
Thicker bristles are stiffer and should be used on smooth floors with narrow joints between tiles. We recommend using soft
bristles when floors are uneven or have deep joints or raised edges.
PAD HOLDER
Pad holder is recommended for cleaning polished surface, there are two types of pad holders:
1.
Traditional pad holders with set of anchor stubs that retain and drive abrasive disk during operation.
2.
CENTER LOCK Pad holders which, in addition to anchor stubs, also have a plastic snap-in centre lock system. This
permits perfect centering of the abrasive disk and ensures it is kept anchored without detaching. This type of pad holder
is best for machines with several brushes.
