MANUFACTURER 

Superabrasive was founded in 1987, as a manufacturer of high quality diamond tools for the stone and concrete industry. Today, 
Superabrasive  is  one  of  the  world’s  leading  companies  in  the  production  of  diamond  tools  and  floor  grinding  machinery.  At 
Superabrasive, we strive to deliver the very best solutions to our customers, and enable them to work more efficiently.  

GENERAL DESCRIPTION 

The  Lavina®  B21-E  machine  is  intended  for  burnishing,  polishing  and  buffing  concrete,  marble,  granite,  limestone  and  terrazzo 
surfaces with diamond tools. 
The Lavina® B21-E is a one-disc machine. 
For best results, use only tools manufactured or recommended by Superabrasive and its distributors.  

The Lavina®B21-E machine is manufactured and fitted for the above-mentioned applications only! Every 

other use may possess risks to the persons involved. 

MACHINE CHARACTERISTICS 

Lavina®B21-E (Fig. 1.1) is a machine for polishing smooth surfaces. For greater efficiency the tool is working at high 
revolutions and full contact with the treated surface.  The moving speed of the operator also influences the polishing 
result. The operator should avoid any obstacle (high or low places) that can contact the tool on the treated surface. 

 

MAIN DESIGN 

The halogen spotlight

 (Fig.1.2) enables the 

operator to work in darker areas.  

Existing lighting 

system does not replace adequate overhead 
lighting.  

The frame

 The handle on the frame is 

adjustable in height and allows the operator 

to work in a correct and safe posture. 

The electrical box 

(fig.1.3) contains the electric switching devices and the inverter

.

 The motor feeding cable is on the bottom 

part of the unit. The 

main feeding cable

 is connected with a plug and socket on top

 

 

The motor

 is mounted on the base plate. The motor is driving the grinding head with a belt system. 

ENVIRONMENTAL CONDITIONS 

The  temperature  range  for  operating  the  Lavina®B21  outdoors  is  between  41°F  and  86°F  or  5°C  and  30°C.  Never  use  the 
Lavina®B21-E during rain or snow when working outdoors. When working indoors, always operate the machine in well-ventilated 
areas. 

ELECTRICAL CONNECTION 

The voltage (Volt) and power (Ampere) are displayed on a label on the electrical control box to avoid any incorrect connection. 
Refer  to  these  before  connecting  the  power.  To  avoid  electrical  shocks,  make  sure  the  ground  power  supply  is  functioning 
properly. 

 

Work with the machine only in 5 (five) wire system of power supply.
