OPERATION 

6.1.

Controls description 

The machine is equipped with the following controls and indicator lights: 

a)  Three LED lights indicate the battery charge level. They may be: 

•

GREEN LED light on: batteries are 100% charged 

•

GREEN & RED LED lights are flashing: batteries are almost flat 

•

RED LED light on: batteries are completely flat 

b)  Brush button (Fig. 1 – Ref. 3): enable brush operation. 

c)  Tap lever (Fig. 7 – Ref. 22): provides continuous control of the flow of water or detergent to the brushes. Pull up 

to increase the liquid outflow. 

d)  Drive lever (Fig. 7 – Ref. 21): moves the machine forwards and rotates the brushes. 

e)  Squeegee lever (Fig. 7 – Ref. 24): raises (when lifted) or lowers (when pushed down) the squeegee. 

f)  Brush pressure adjustment: turn the knob to adjust brush pressure on the surface being cleaned. 

g)  Head lowering/rising pedal (Fig. 7 – Ref. 26): press it to lower or raise the brush head. 

h)  Vacuum motor switch (Fig. 1 – Ref. 4) 

6.2.

Squeegee mounting and adjustment 

The squeegee (Fig. 7 - Ref. 27) is responsible for drying. The mounting of the squeegee can be proceeded as follow: 

a)  Lift the squeegee mount (Fig. 7 – Ref. 24) 
b)  Insert the suction hose sleeve (Fig. 7 – Ref. 28) fully into the squeegee. 
c)  Insert the two threaded pins into the slots on the support and fix the squeegee by tightening the two knobs (Fig. 7 

– Ref” 27). 

The squeegee blades can scrape the water and detergent from the floor and prepare the way for perfect drying. As 
time goes by, the constant rubbing makes the edge of blade in contact with the floor rounded and cracked, reducing 
its dry efficiency. 

As a result, the state of the squeegee should be checked frequently. For perfect drying, the squeegee must be 
adjusted in such a way that the edge of rear blade bends during operation by about 45

o

 with respect to the floor at 

every point. Adjust blade’s angle during operation by regulating the height of the two wheels positioned behind 
squeegee. 

6.3.

Moving the machine without operating it 

To move the machine without operation: 

a)  Lift the squeegee. 
b)  Push the head pedal down toward the right to lift the head. 
c)  Push or pull the machine with mechanical drive. 

6.4.

Brush mounting and adjustment 

Never work without brushes, rollers or drive disks perfectly installed. 

Fitting the brush: rest the brush on the floor in front of the machine and center it with the guard. Lower the head and 
repeatedly action the brush control lever until the brush automatically engages on the flange hub. If this manoeuvre is 
not successful, press on the handle again and repeat the centring and repeated action of the brush lever.  

Remove the brush: raise the machine head by pushing the head lift pedal down and then to the right and repeatedly 
action the brush lever. After a few pulses, the brush is released and falls to the ground.
