maintenance  in  the  engine’s  operating  and  maintenance  instructions,  especially  as  regards 

controlling the engine oil, the air filter and the spark plug.

•  During use, the appliance should not be too noisy and large amounts of liquid or oil should 

not drip from underneath it.

In this event, a Skilled Technician should test the appliance.

6.2.1  Diaphragm rupture  
The rupture of one or more diaphragms can result in the mechanical parts of the pump being 

damaged by the liquids being pumped.

The following are symptoms of possible diaphragm rupture:

-  oil takes on a whitish appearance (symptom of water in the oil)

-  excessive consumption of oil

-  sudden lack of oil in the volumetric compensator (32).

•  To avoid the negative consequences of this malfunction, stop operation of the appliance 

immediately and contact a Skilled Technician without delay (within 24 hours) who will 

take the necessary action.

  If  it  is  not  possible  to  contact  a  Skilled  Technician  within  the  above  time  in  case  of
