Alw ays empty the recovery tank ( Photo N - 4)
before filling the solution tank ( Photo N - 3).
To fill the tank:
- Pour into the tank the required quantity of the
chemical product, considering the percentage indi-
cated by the supplier, w ith reference to the full tank
capacity listed on the product sheet.
Use only those products suitable for the floor
and the dirt to be removed.
- Pour w ater in the filling opening placed in the
front of the machine ( Photo H - 2, Photo N - 2 ).
Leave 2 cm betw een the filling opening and the
liquid level. Do not fill beyond this point!
The machine w as designed to be used w ith
non-foaming and biodegradable detergents made

The dirty w ater must be drained in accordance w ith
national regulations.
The user is completely responsible for ensuring
compliance w ith such rules.
After the detergent solution is finished, alw ays
empty the recovery tank ( Photo N - 3) before fil-
ling it again.
In general, the recovery tank can be emptied w he-
never required, and even during intermediate pha-
ses of the w ork cycle.
The recovery tank volume is higher than the deter-
gent solution volume, therefore a potentially dan-
gerous situation for the suction motor should never
occur. In any case, a safety float ( Photo O - 1) w ill
stop the suction if the dirty liquid level is too high.
If w ater or foam starts leaking from under the
tanks for any reason, immediately turn off the suc-
tion motor and empty the recovery tank.
To drain the tank:
Drive the machine to a suitable location to drain
the dirty w ater and preferably near a toilet or a
sew er drain (comply w ith the national regulations
for w aste w ater disposal).
Turn off the machine and remove the key from the
panel.
Detach the drain hose from the holder ( Photo B
- 6, D - 6, F - 7 ) and, keeping it high, unscrew
the plug.
Low er the drain hose tow ard the selected drainage
point.
The emptying operation can be interrupted quickly
and w henever required j ust by raising the drain
hose.
Check how
much dirt is still in the tank and, if ne-
cessary, w ash it inside through the inspection hole
( Photo O - 3).
Fully tighten the drain hose w ith the screw
and hang it on the support behind the machine.
The drain hose plug must be airtight, otherw ise
the subsequent pressure loss w ill reduce drying
efficiency.
