Modifications And Spare Parts; Troubleshooting - ARVEN CUTTER Serie Manual De Instrucciones

In any case, all repair and maintenance jobs must be carried out only after having disconnected
the pump from the power mains, once made sure that it cannot suddenly begin working.During
dismantling it is necessary to pay great attention to sharp parts which may cause injury.The cut-

of water. Sand and other abrasive materials cause precocious wear and tear, as well as loss of
performances.
