Tornado BDSO 20/21, Operation & Maintenance Manual

12

Carefully follow the instructions provided 

by the battery charger and the batteries 

manufacturers.

NOTE:

 Never leave the batteries completely 

discharged for long periods of time even if 

the machine is not used. In case of traditional 

batteries, please check the electrolyte level 

every 20 charging cycles and eventually fill 

them up with distilled water. Never leave the 

batteries discharged for more than two weeks.

If lead/acid batteries are installed there could 

be the risk of gas exhalations and emission of 

corrosive liquids.

Fire danger: do not approach with free flames.

The two splash guards must be assembled on 

the brush base cover.

1. Insert the metal supports inside the 

dedicated housings on the rubber. Place the 

round hole to the plain end of the support on 

the screw in front of the cover. Secure the

supports by tightening the nut.

2. Screw the screws on the rear part of the 

cover, on the free end of the metal supports

and the locks.

With the brush base lifted, manually rotate the 

brush until the central screw, where to fix the 

support and to lock the brush, can be seen. 

Secure the brush as shown in the picture. 

ASSEMBLING THE BRUSH

To assemble the brush it is necessary to have 

the brush base lifted from the floor. If it is not in 

such position, proceed as follows:

Without having an operator aboard, turn 

the key to switch on the display, then after  

3 seconds, automatically all the working 

assemblies will reset themselves and lift from 

the floor.

Turn off the machine using the key switch.

ASSEMBLING AND DISASSEMBLING THE 

SPLASH GUARDS

Use only brushes provided with the machine 

or the ones specified on the “BRUSHES and 

OPTIONAL” manual. Using other brushes could

compromise the good cleaning.

The operation has to be made for both the 

splash guards rubbers.

With the brush on, the splash guard rubber has 

to slightly touch the floor.

To disassemble the supports just repeat these 

operations in reverse order.
