DETERGENT SOLUTION
After filling the solution tank with clean water add the liquid detergent to the tank in the concentration and manner indicated on the detergent manufacturer's label.
To prevent the formation of an excessive amount of foam that could damage the vacuum motor, use the minimum percentage of detergent required.
CAUTION : Protective gloves should always be worn when handling detergents or acidic or alkaline solutions, to avoid serious injury to the hands.
ATTENTION : Always use detergents whose manufacturer's label indicates their suitability for scrubbing machines. Do not use acid or alkaline products or solvents without this indication.
N.B. : Always use low-foam detergent. To avoid the production of foam, put a minimum quantity of antifoam liquid in the recovery tank before starting to clean. Do not use pure acids.
For versions with automatic management system of chemical products, fill the solution tank with clean water and then proceed as follows:
1. Bring the machine to the area designated for refilling the solution tank.
2. Make sure the machine has been secured (see the section titled “ SECURING THE MACHINE ”).
3. Unhook the tank rotation latch (1) ( Fig. 1 ) and turn the recovery tank into the maintenance position ( Fig. 2 ).
4. Disconnect the male insert (2) from the female insert (3) present on the cap (4) for the detergent tank (5) ( Fig. 3 ).
NOTE : Before pulling on the male insert, push the lever on the female insert.
5. Gripping the handle (6) on the detergent canister (5), remove the canister from the compartment in the solution tank ( Fig. 4 ).
6. Remove the cap (4) from the detergent canister (5) Fig. 5 ).
7. Fill the canister with the desired detergent, as shown on the label supplied with the appliance.
CAUTION : Protective gloves should always be worn before handling detergents or acidic or alkaline solutions, to avoid serious injury to the hands.
N.B. : Always use low-foam detergent. To avoid the production of foam, put a minimum quantity of antifoam liquid in the recovery tank before starting to clean. Do not use pure acids.

CAUTION : These operations must be carried out using protective gloves to avoid any possible contact with the edges or tips of metal objects.
2. Unscrew the knobs (1) in the squeegee body pre-assembly ( Fig. 1 ).
3. Insert the right pin (2) on the squeegee body into the right slit (3) in the squeegee support ( Fig. 2 ), making sure that the washer and spring adhere to the top of the squeegee support.
4. Repeat the same operation for the left knob.
5. Tighten the knobs (1), ensuring that the washer and spring adhere to the top part of the squeegee support ( Fig. 3 ).
6. Insert the vacuum tube (4) in the sleeve (5) in the squeegee body ( Fig. 4 ).
N.B. : Although the squeegee comes pre-adjusted, it is nevertheless recommended to read the section titled “ ADJUSTING THE SQUEEGEE BODY'S RUBBER BLADES ”.
