SPARE PARTS AND MAINTENANCE
All necessary operating, maintenance and repair procedures must be performed by qualified personnel or by Advance Service
Centers.
Only original spare parts and accessories must be used.
Contact Advance for service or to order spare parts and accessories, specifying the machine model and serial number.
CHANGES AND IMPROVEMENTS
Advance constantly improves its products and reserves the right to make changes and improvements at its discretion without being
obliged to apply such benefits to the machines that were previously sold.
Any change and/or addition of accessory must be approved and performed by Advance.
OPERATION CAPABILITIES
This scrubber-dryer is used to clean (scrubbing and drying) smooth and solid floors, in civil or industrial environment, under safe
operation conditions by a qualified operator.
The scrubber-dryer cannot be used for moquette and carpet cleaning.
CONVENTIONS
Forward and backward, front and rear, left and right references are intended with the operator in driving position with the hands on
the handlebar (1).
UNPACKING/DELIVERY
To unpack the machine, carefully follow the instructions on the packing.
Upon delivery carefully check that the machine and its packing have not been 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 fill in a damage claim.
Check that the machine is equipped with the following features:
Technical documents:–

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.

When finishing working, it is advisable to remove the brush/pad in order not to drag it on the floor and leave wet marks (see3.
the procedure in the relevant paragraph).
TANK EMPTYING
An automatic float shut-off system (25) turns off the vacuum system when the recovery tank (23) is full.
The vacuum system shutdown, due to the recovery tank filling, is signalled by an increase in the vacuum system motor noise,
moreover the floor is not dried.
CAUTION!
If the vacuum system turns off accidentally (for example, when the float is activated because of a sudden
machine movement), to resume the operation: turn off the machine with the knob (32), check that the float inside
the grid (25) has gone down to the water level. Then turn on the vacuum system by pressing the knob (32).
When the recovery tank (23) is full, empty it according to the following procedure.
Recovery tank emptying
Switch off the machine by turning the knob (32) to “0”.1.
Drive the machine to the appointed disposal area.2.
Remove the transparent cover (24).3.
Grab the handle (A, Fig. 3) and lift the recovery tank (B).4.
Drain the recovery tank. Then, rinse the tank with clean water.5.
