Filling And Draining The Deter- Gent Solution Tank; Draining The Recovery Tank; Seat Adjustment - LAVOR Pro COMFORT S-R 66 Bedienungsanleitung

Working with excessively worn brushes or excessi-
vely thin abrasive disks may damage the machine
and the floor.
Regularly check the wear on these parts before
starting to work.
Disassembly or replacement:
Make sure that the brush plate is raised; otherwise
lift it by following the instructions provided in the
specific section.
Make sure that the ignition key on the control panel
is in position "0".
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.
7.4 FILLING AND DRAINING THE DETER-
GENT SOLUTION TANK
☞
( ) The temperature of the water or the de-
tergent should never exceed 50°C.
☞
( ) Always empty the detergent solution tank be-
fore filling it up.
To fill the solution tank:
• Remove the plug in the back of the machine.
• Leave 7 cm between the mouth of the plug and
the liquid level. Do not fill beyond this point!
• Add the required quantity of the chemical pro-
duct, considering the percentage indicated by the
supplier, with reference to the full tank capacity li-
sted 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 deter-
gents 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 re-
lative section and indicated on the detergent con-
tainer.
• Contact the machine manufacturer to obtain a
complete list of available and suitable detergents.
• •Always add the detergent after filling the tank
with water to prevent foam from being created in-
side.
• Do not leave the water hose unattended and in-
sert 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:
• Open the valve located at the bottom of the ma-
chine in the back ( Photo B - 5 ; Photo Q - 3 ) and
wait until the tank has been completely emptied.
• Close the drain valve.

7.5 DRAINING THE RECOVERY TANK

The dirty water must be drained in accordance with
national regulations.
The user is completely responsible for ensuring
compliance 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 whe-
never required, and even during intermediate pha-
ses 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 turns off the suc-
tion 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 suc-
tion 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 and remove the key from the
panel.
Detach the drain hose from the hook 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 the quantity of residual dirt in the tank and,
if necessary, clean the interior through the inspec-
tion hole, lifting the cover and the funnel at the top.
Carefully position the funnel inside the inspection
hole and close the top cover, tightening the lock
handles after each inspection/cleaning operation.
Fully tighten the drain hose with the screw plug and
hang it on the support behind the machine.
☞
( ) The top cover of the tank and the drain hose
plug must be airtight, otherwise the subsequent
pressure loss will reduce drying efficiency.

7.6 SEAT ADJUSTMENT

Before adjusting the seat, make sure that the ma-
chine is turned off and that the key has been re-
moved from the dashboard.
If necessary, the position of the driver's seat can be
changed.
To change the seat adjustment, release the locking
lever and move the seat to the required position.
Make sure that the locking lever is securely fixed at
the end of the adjustment.
Check that the seat is in a stable position and firmly
