From the control position the operator must be able to see the entire apparatus and the surrounding area. Within the area 

you must prevent access to unauthorized persons and objects that may constitute a source of danger. 

All  the  installation  operations  involving  connections  with  outside  main  supplies  (especially  electricity)  must  be  done  by 

professionally qualified people. 

Installation must be done by authorized personnel following the special instructions contained in the manual where necessary. 

In case of doubt, consult authorized service centre or the technical services office of Balance. 

 

Safety 

Any tampering or alteration of the apparatus which is not previously authorized by the manufacturer will release the latter from 

any liability for damages deriving from or referring to the above-mentioned actions. 

Removal or tampering with the safety devices constitutes violation of the safety regulations. 

The operator must also observe the following safety procedures: 

 

Check that dangerous conditions do not arise during the operation maneuvers. Stop the machine immediately in case of 

irregular functioning and contact the customer service office of the authorized retailer. 

 

Check that the working area around the machine is free of potentially dangerous objects and that there is no oil (or other 

sticky materials) on the flooring since this is a potential danger for the operator. 

 

The  operator  must  wear  suitable  work  clothing,  protective  goggles,  gloves  and  mask  to  prevent  harm  from  dust  or 

impurities  being  blown  out.  Dangling  objects  such  as  bracelets  should  not  be  worn,  long  hair  should  be  protected  in  a 

suitable manner, shoes should be suitable for the type of operation to be performed. 

 

Technical service, repairs and replacement of parts   

All repair and extraordinary maintenance operations should be carried out by authorized and professionally qualified personne l. 

Disconnect the machine from the mains supplies (electricity, compressed air, etc.) before any maintenance operation. 

Use original spare parts supplied by the manufacturer. 

Consult the technical services office of Balance for any doubt regarding the suitability and conformity to safety regulations of the 

accessories and spare parts to be used on the machine. 

 

Storing   

Should the machine have to placed in storage for a long period, disconnect the main supplies, empty the tanks containing the 

operating  liquids  and  make  sure  that  those  parts  which  could  be  damaged  by  the  deposit  of  dust  are  adequately  protected. 

Grease  those  parts  which  could  be  damaged  due  to  drying  out  and,  when  the  machine  is  used  again,  replace  the  gaskets 

indicated in the spare parts section. 

 

Scrapping   

If the machine is not to be used again, it should be made inoperative. 

Those parts which could cause danger should be rendered harmless. 

Consult disposal classification lists for the disposal category of the product. 

Scrap as iron scrap and send to the appropriate refuse collection centre. 

If it is considered special waste, dismantle and divide into similar parts before disposing in accordance with the regulations in 

force.
