While holding the brushes (or the guide disks) with
the hands under the plate, turn them in the rotation
direction while lowering to release them from the
guide plate.
7.9 FILLING AND DRAINING THE DETER-
GENT SOLUTION TANK
☞
The temperature of the water or the detergent
should never exceed 50°C.
☞
Always empty the detergent solution tank before
filling it up.
To fill the solution tank:
- Remove the plug on the machine (Foto A-9) .
- Leave some space between the mouth of the plug
and the liquid level.
- Add the required quantity of the chemical product,
considering the percentage indicated by the supplier,
with 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.
•
The machine was designed to be used with
non-foaming and biodegradable detergents made
specifically for scrubber-driers. The use of other
chemical products (such as sodium hypochlorite,
oxidisers, solvents or hydrocarbons) may damage
or destroy the machine.
- Follow the safety regulations specified in the rela-
tive section and indicated on the detergent container.
- Contact the machine manufacturer to obtain a com-
plete list of available and suitable detergents.
•
Always add the detergent after filling the tank with
water to prevent foam from being created inside.
- Do not leave the water hose unattended and insert
it completely into the tank: the hose might move and
get sensitive parts of the machine wet.
- Close the tank cover.
To drain the solution water tank:
- Unscrew the plug placed in the machine lower area
(Foto C-23) and wait for the complete tank emptying.
- After the emptying operation, screw and fully
tighten the drain plug.
7.10 DRAINING THE RECOVERY TANK
The dirty water must be drained in accordance with
national regulations.
The user is completely responsible for ensuring com-
pliance with such rules.
After the detergent solution is finished, always empty
the recovery tank before filling it again.
In general, the recovery tank can be emptied when-
ever required, and even during intermediate phases
of the work cycle.
•
Always empty the recovery tank before lifting it
to avoid health problems for operators and to avoid
damaging the machine.
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 (Foto F-43) turns off
the suction motor if the dirty liquid level is too high.
•
If water or foam starts leaking from under the
tanks for any reason, immediately turn off the suction
motor and empty the recovery tank.
To drain the tank:
Drive the machine to a suitable location to drain the
dirty water and preferably near a toilet or a sewer
drain (comply with the national regulations for waste
water disposal).
Turn off the machine.
Detach the drain hose from the holder (Foto A-7)(Foto
A-8) and, keeping it high, unscrew the plug.
Lower the drain hose toward the selected drainage
point.
The emptying operation can be interrupted quickly
and whenever required just by raising the drain hose.
Check how much dirt is still in the tank and, if neces-
sary, wash it inside through the inspection hole.
Fully tighten the drain hose with the screw plug and
hang it on the support behind the machine. The drain
hose plug must be airtight, otherwise the subsequent
pressure loss will reduce drying efficiency.
7.11 ADJUSTING THE SOLUTION WATER
FLOW
Set the solution flow control lever (Foto C-22) in an
intermediate position between the closed and fully
opened position, according to the kind of cleaning
to be performed.
Solution water valve closed
Solution water valve partially opened
Solution water valve fully opened
7.12 DRIVING THE MACHINE
Model AC 230V
- Connect the power cable of the machine (Foto B-16)
to the power mains using a patch cord.
- Switch ON the main ON-OFF switch (Foto E-32) .
