OPERATION CAPABILITIES
This scrubber-dryer is used to clean (scrubbing and drying) smooth and solid oors, in civil or industrial environment, under safe
operation conditions by a qualied operator.
The scrubber-dryer cannot be used for tted carpet and carpet cleaning.
CONVENTIONS
Forward, backward, front, rear, left or right are intended with reference to the operator’s position, that is to say in driving position
with the hands on the handlebar (2).
UNPACKING/DELIVERY
To unpack the machine, carefully follow the instructions on the packing.
When the machine is delivered, check that the packing and the machine were not damaged during transportation.
In case of visible damages, keep the packing and have it checked by the carrier that delivered it. Call the carrier immediately to ll
in a damage claim.
Please check that the following items have been supplied with the machine:
– Technical documents:
• Scrubber-dryer Instruction for use Manual
• Battery Charger Manual
• Scrubber-dryer Spare Parts List
– No. 2 lamellar fuses
SAFETY
The following symbols indicate potentially dangerous situations. Always read this information carefully and take all necessary
precautions to safeguard people and property.
The operator’s cooperation is essential in order to prevent injury. No accident prevention program is effective without the total
cooperation of the person responsible for the machine operation. Most of the accidents that may occur in a factory, while working
or moving around, are caused by failure to comply with the simplest rules for exercising prudence. A careful and prudent operator is
the best guarantee against accidents and is essential for successful completion of any prevention program.

This machine is not suitable for collecting dangerous powders.
–When using lead (WET) batteries, keep sparks, ames and smoking materials away from the batteries. During
the normal operation explosive gases are released.
–When using lead (WET) batteries, battery charging produces highly explosive hydrogen gas. During battery
charging, remove the recovery tank and perform this procedure in well-ventilated areas and away from naked
ames.
WARNING!
–Carefully read all the instructions before performing any maintenance/repair procedure.
–Before using the battery charger, ensure that frequency and voltage values, indicated on the machine serial
number plate, match the electrical mains voltage.
–Do not pull or carry the machine by the battery charger cable and never use the battery charger cable as
a handle. Do not close a door on the battery charger cable, or pull the battery charger cable around sharp
edges or corners. Do not run the machine on the battery charger cable.
–Keep the battery charger cable away from heated surfaces.
–Do not charge the batteries if the battery charger cable or the plug are damaged. If the machine is not

• ECO system: when the lever (36) is turned to ECO position (37), the machine works in a special condition of programmed
water “economy” usage; as the water ow is set and constant, the machine can work with a washing autonomy of ~ 90
minutes (0.4 liters/min average).
• Variable system: when the lever is turned to the left (variable ow) the ow rate can increase up to 1.6 liters/min (when the
tank is full), with an autonomy of ~ 40 minutes.
5. Press the brush/pad-holder switch (41) and the vacuum system switch (42).
6. Press the push-button (47) to enable the brush/pad-holder.
7. Start cleaning, by moving the machines with the handlebar (2).
NOTE
If the green LED (44) turns on, the machine is ready to be used. If the yellow or red LED (45 or 46) turns on, the batteries
must be charged (see the procedure in Maintenance chapter).
Stopping the machine
8. Stop the machine and the brush/pad-holder by releasing the push-button (47).
9. Turn off the brush/pad-holder and the vacuum system by pressing the switches (41) and (42).
10. Lift the squeegee (21) with the lever (7).
11. With the handlebar (2) slightly lower the machine until the rear wheel (6) comes into contact with the oor (parking position
(27)).

MACHINE OPERATION (SCRUBBING/DRYING)
1. Start the machine as shown in the previous paragraph.
2. While keeping both hands on the handlebar (2), press the push-button (47), then manoeuvre the machine and start scrubbing/
drying the oor.
3. If necessary, stop the machine and adjust the squeegee balancing handwheel (23).
4. If necessary, adjust the solution quantity by using the valve (36).
CAUTION!
To avoid any damage to the oor surface, turn off the brush/pad-holder when the machine stops in one place.
CAUTION!
Before lifting the brush/pad, turn it off by releasing the push-button (47).
NOTE
For correct scrubbing/drying of oors at the sides of the walls, Advance suggests to go near the walls with the right side
of the machine as shown in gure 4.

Figure 4
P100664
CAUTION!
In case of brush/pad-holder motor overload, due to foreign bodies which prevent them from turning, or to
excessively aggressive oors/brushes, the safety system stops the brush/pad-holder after about one minute of
continuous overload.
The overload is shown by the three LEDs (44, 45, 46) ashing simultaneously.
To start scrubbing again after a brush/pad-holder stop due to overload, stop the machine by turning the brush/
pad-holder switch and the vacuum system switch (41 and 42) to “0”. Turn on the machine by turning the brush/
pad-holder switch and the vacuum system switch (41 and 42) to “I”.
Battery discharge during operation
5. Until the green LED (44) stays on, the batteries allow the machine to work normally. When the green LED (44) turns off and the
yellow and red LED (45) and (46) turn on in sequence, it is necessary to charge the battery as the machine residual autonomy
is at the minimum level.
CAUTION!
Do not use the machine with discharged batteries, to avoid damaging the batteries and reducing the battery life.
Machine speed adjustment
6. The machine speed varies according to the type of oor to be cleaned and the choice of using the brush or the pad. If
necessary, stop the machine and turn the forward speed adjusting handwheel (25) as shown below:
• Turn it counter-clockwise to increase the forward speed;
• Turn it clockwise to decrease the forward speed.
Machine straight-forward drive
7. If it is difcult to keep the machine moving straight-forwardly because it deviates to the left or to the right, adjust the handwheel
(24) by turning it clockwise or counter-clockwise.

MACHINE TRANSPORT/PARKING
To transport/park the machine, proceed as follows.
1. Turn the brush/pad-holder switch and the vacuum system switch (41 and 42) to “0”.
2. Lift the squeegee with the lever (7).
3. Grab the handlebar (2) and slightly lower it until the brush lifts from the oor. While holding the machine in this position, drive
it to the appointed parking area. Then lower the machine until the rear wheel (6) comes into contact with the oor (parking
position (27)).
4. When nishing working, remove the brush/pad-holder (see the procedure in Maintenance chapter).
TANK EMPTYING
An automatic oat shut-off system (30) turns off the vacuum system when the recovery tank (16) is full.
The vacuum system deactivation is signalled by a sudden increase in the vacuum system motor noise frequency, and the oor is
not dried.
CAUTION!
If the vacuum system turns off accidentally (for example, when the oat is activated because of a sudden
machine movement), to resume the operation: turn off the vacuum system by pressing the switch (42), then
open the cover (17) and check that the oat inside the grid (30) has gone down to the water level. Then close the
cover (17) and turn on the vacuum system by pressing the switch (42).
When the recovery tank (16) is full, empty it according to the following procedure.
Recovery tank emptying
1. Turn the brush/pad-holder switch and the vacuum system switch (41 and 42) to “0”.
2. Lift the squeegee with the lever (7).
3. Drive the machine to the appointed disposal area.
4. Grasp the handlebar (2) and slightly lower it until the rear wheel (6) comes into contact with the oor.
5. Empty the recovery tank with the drain hose (11). Then, rinse the tank with clean water.
Solution tank emptying
6. Perform steps 1 to 4.
7. Empty the solution tank with the hose (12). Then, rinse the tank with clean water.
AFTER USING THE MACHINE
After working, before leaving the machine:
1. Turn the brush/pad-holder switch and the vacuum system switch (41 and 42) to “0”.
2. Remove the brush/pad-holder as shown in Maintenance chapter.
3. Empty the tanks (15 and 16) as shown in the previous paragraph.
4. Perform the daily maintenance procedures (see the Maintenance chapter).
5. Store the machine in a clean and dry place, with the brush/pad-holder and the squeegee lifted or removed.
