OPERATION
Adjustment Of The Base Pressure
Through the wing nut (1) it is possible to adjust the base pressure on the cleaned
surface.
By turning the wing nut clockwise the pressure increases, rotating the wing nut
counterclockwise, the pressure decreases.
This device allows a more efficient cleaning action on very difficult and dirty
surfaces.
In order not to overload the base motor, it is recommended to reduce the base
pressure when going from smooth floors to rough ones (ex. concrete).
Overflow Device
In order to avoid serious damages to the suction motor, the machine is equipped
with a float that intervenes when the recovery tank is full, closing off the suction
hose and stopping the suction.
When this happens, it is necessary to empty the recovery tank.
1. Remove the drain hose placed in the front part of the machine.
2. Take off the exhaust plug by pulling the lever and empty the recovery tank into
appropriate containers, according to the standard norms.
