ORDINARY AND SPECIAL MAINTENANCE  

 
 

Periodically and at least once every year, clean the coaxial electric contacts of connection between 
the pivot of the generator and the supporting bush by qualified personnel. 
 
It  is  essential  to  carefully  remove  any  possible  formation  of  brass  powder  due  to  the  use  of  the 
equipment.  
 
Every  year,  or  when  it  is  necessary,  verify  the  lubrication  of  the  moving  components  and  of  the 
joints by qualified personnel. 

 

If  the  movement  of  setting  should  be  too  much  hard,  do  not  insist  to  avoid  any  problem  of 
damaging.  
 
Any  servicing  should  be  carried  out  by  qualified  personnel  authorized  by  ARDET  Dental  & 
Medical Devices s.r.l.  
 
Every twelve months check:  

 

a)

 

That the nameplates are complete and legible 

b)

 

That the ABS coverings are upright  

c)

 

That the x-ray control board is upright.  

d)

 

The integrity of the coiled cord of the x-ray remote control (if installed) 

e)

 

The setting of the balancing spring 

f)

 

Check the insulation of the feeding cable 

 

Every year check the parameters of operation (high tension, exposure time, tube current).  
 

 

CLEANING AND DISINFECTION  

 

 
Products like polish or car-wax, normally available on the market, are suitable for a normal cleaning 
of finished surfaces. 
 
Any oil residue can be wiped off by using alcohol and passed again with a light layer of  polish or 
car-wax.  
 
Do not insist on passing alcohol on nameplates and plastic parts.  

 

For  any  disinfection  (The  rubber  protection  of  the  collimator,  which  is  in  contact  with  the  skin, 
etc.),  use  a  cold  system  of  disinfection  normally  used  in  surgery  such  as  a  solution  of  quaternary 
ammonium  /  glutamate  aldehyde  with  a  maximum  concentration  of 

2%, 

or  any  other  cooling 

disinfection systems registered by the Ministry of Health. . 

CAUTION!
