GENERAL DESCRIPTION 

The 

Lavina®21-X 

machine is intended for grinding, polishing, and buffing concrete, marble, granite, limestone, and 

terrazzo surfaces with diamond tools.

 

The 

Lavina®21-X is a three-disc machine, which can be used dry as well as wet. 

For best results, use only tools manufactured or recommended by Superabrasive  and its distributors. Additionally, the 
machine could be used for grinding wood floor surfaces. 
 

 The 

Lavina®21-X  machine is manufactured and fitted for the above-mentioned applications only! 

Every other use may possess risks to the persons involved. 
 

MACHINE CHARACTERISTICS 

The 

Lavina®21-X is made of two main component sections: 

 

LAVINA 21 MAIN DESIGN 

 

The two main component sections

, the carriage (1)

 

and main head (2). 

 

The handle on the frame

 is adjustable in height and allows the operator  

            to work in a correct and safe posture. 

 

The controls

 are positioned on top of the frame. 

 

The  electrical  box 

(fig.1.2)  contains  the  electric  switching  devices.  The 

motor feeding cable and the main feeding cable are plugged in the socket 
located on the bottom of the frame. 

 

The water tank

 is on the opposite side of the frame, so that the weight of 

the  water  has  no  influence  on  the  operation  of  the  machine.  The  frame 
weight, on the other hand, is fully absorbed by the driving wheels. 

 

The motor

, mounted on the base plate,  is driving the three heads with a 

belt system. The 

planetary head

 is driven by a second belt. 

 

 The  self-leveling  Guard

  is  designed  to  have  contact  with  the  surface. 

Anytime, no matter the height of the tool used. 

 

 
 
 
ENVIRONMENTAL CONDITIONS 

The 

temperature range for operating the LAVINA® X machine outdoors is between 

41°F and 86°F or 5°C and 30°C. Never use the LAVINA® X machine 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.
