chemical outlet
 Check the Washing function (brushdeck movement, water supply and brush rotation)
 Check the Drying function (movement of the squeegee, operation of the suction motor and the sealing of
the recovery tank)
 Check the Traction (Forward, Backward and Braking)
 Proceed with on-site adjustments (brushdeck and Squeegee adjustment)
 Check the functioning of the Optional if present:
–Rear camera
–Anti-collision sensors
–Front lights
–Service lights
–Wand Kit
–Gun Kit
 Once the demo has been completed, immediately perform the daily maintenance (see the Use and Main-
tenance manual).
1.10.2 Demo Tips:
Squeegee
You need to have a complete squeegee with a length different from the original (wider or narrower) if available.
You need to have an alternative squeegee rubber kits in PARA and Polyurethane with different hardness (see
section ?? at page ??).
Brushes
You need to have alternative brushes in PPL of different thickness (see section ?? at page ??).
You need to have a pad holder and various PAD at different hardness (see section ?? at page ??).
Chemical
You Always need to have the detergent available.
You need to have the Anti-foaming liquid (in case the customer uses his chemical).
