Adjusting The Squeegee; Cleaning The Disc Brushes And The Abrasive Discs - NSS CHAMP 2417 RB Manual De Uso

Adjusting the squeegee

The squeegee must be properly adjusted in order to ensure a perfect drying of the fl oor. The scrubber drier uses a
"BENT" squeegee as shown in the picture.
The feature of this type of squeegee is a good water drain to the suction hose, although it is sensitive to the parallel
inclination to the ground.
The perfect working angle to the ground is essential for a proper functioning of the squeegee. The squeegee rear
rubber (A) should work in the maximum vertical position as possible and on its edge, as shown in the picture, so that
fl uids are drained through the front side of the rubber.
This can be achieved by following the procedure below:
• Adjust the screw (B) by turning it clockwise (fastening) to increase the squeegee inclination or anticlockwise
(unfastening) to decrease it.
Depending on the diff erent fl oor types to dry and the rubber wear and tear, the height of the squeegee from the
ground should be adjusted by turning the nuts (C) as follows:
• Turn the nuts clockwise to increase the height of the squeegee from the ground and reduce its weight on the
fl oor.
• Turn the nuts anti-clockwise to decrease the height of the squeegee from the ground and increase its weight
on the fl oor.
The same nuts (C) can also be used to adjust the squeegee and make it work parallel to the fl oor.
For a longer rubber life, pressure should be the minimum required still achieving a proper drying.
Be careful that the drying stage is often negatively aff ected by a vacuum malfunctioning, and in this case:
• The vacuum pipes, the inlets, the fi lters and the squeegee should be perfectly cleaned.
• Check that the vacuum motor is working properly.
• Check that all inspection doors of the tank are properly closed.
Cleaning the disc brushes or the "abrasive
discs - upon request".

WARNING!
It is advisable to use protective gloves when
cleaning the disc brushes or the abrasive
discs since sharp debris may be attached to
it.
• Disassemble the disc brushes or the abrasive discs
if necessary (See procedure in the specifi c section).
• Wash and clean the disc brushes or the abrasive
discs (D) from dirt and debris.
• Fit the disc brushes or the abrasive discs back in
place if previously disassembled (See procedure in
the specifi c section).
• The disc brushes or the abrasive discs should be
replaced for excessive wear when, with the brush
lowered, the side pins (E) rest on the lower ends (F)
of the slots.
