Cleaning the diverter valve
! INFORMATION: This procedure should take place in an area suitable for servicing operations, as the floor will become dirty and wet.
! WARNING: Wear overalls, non-slip shoes, gloves and all other items of PPE appropriate for the work environment.
• Remove the dirty water tank and the detergent tank and set them on the floor, referring to the section “Emptying the
water/detergent tank” and “Emptying the dirty water tank”.
• Detach the front squeegee suction hose from the diverter valve.
• Detach the rear squeegee suction hose from the diverter valve.
• Release the retaining lever (fig. 35, ref. 1) and remove the cover of the diverter valve.
• Clean the chamber of the valve (fig. 36, ref. 1), removing any encrustations, and rinse with clean water; wipe the seals of
thecover with a soft cloth.
Cleaning the squeegee
! WARNING: Do not clean seals with ethyl alcohol.
The operator must always use personal protection devices.
• Remove the dirty water tank and the detergent tank and set them on the floor, referring to the section “Emptying the
water/detergent tank” and “Emptying the dirty water tank”.
• Pull the handle up perpendicular to the machine.
• Tilt the machine backwards and rest the handle on the floor.
• Clean the blades of both squeegees with a moist cloth (fig. 37, ref. 1).
• Clean the suction inlet port of both squeegees (fig. 37, ref. 2).
Squeegee adjustment
The squeegee is factory-adjusted to give an optimum drying action on different types of floor surface, but in the event that results
do not meet expectations, there are further adjustments that can be made. To ensure a faultless drying action, the lip of the
squeegee blade should deflect 45° along its entire length, relative to the floor surface; the height of the squeegee can be adjusted
by raising or lowering the wheels (fig. 38, ref. 1).
Replacing the squeegee blades
The squeegee blades collect the film of water and detergent from the floor and prepare the way for perfect drying. With time, the
constant wiping action causes the edge of the blade in contact with the floor to become rounded and cracked, with the result that
drying is less thorough and the blade must be replaced. Proceed as follows:
• Remove the dirty water tank and the detergent tank and set them on the floor, referring to the section “Emptying the
water/detergent tank” and “Emptying the dirty water tank”.
• Pull the handle up perpendicular to the machine.
• Tilt the machine backwards and rest the handle on the floor.
