C-150-200D                                                       V16 

Page 11 

(Continued) 

Symptom 

Cause and Rectification 

Noisiness 

The  pump  sucks  air.  One  or  more  valve  springs  are  broken  or 
down.  Extraneous  matter  in  the  valves.  Crankcase  or  motor 
bearings worn out.

 

 
Inspect the low-pressure supply. Replace springs. Clean the valves. 
Replace the bearings. 
 

Water in the oil 

The  O-ring  casing  is  worn  out.  High  moisture  in  the  air 
(condensing  inside  the  crankcase)  The  seals  are  completely  worn 
out. 

 
Check or replace the O-ring. 
Renewal of the crankcase oil more often. 
Replace the seals. 

 

When using chemical injector 

 

The High Pressure 
Cleaner does not 
suck chemicals 

The  chemical  container  is  empty.  The  High  Pressure  Cleaner  has 
not been set to low-pressure (on the double barrel lance cock). The 
low-pressure  nozzle  is  clogged,  or  partly  clogged.  The  non-return 
valve of the chemical injector is stuck. 

 
Ensure  the  chemical  container  contains  sufficient  fluid  for  proper 
suction. 
Set the spray-lance to low pressure by turning the cock on the lance 
counterclockwise. 
Clean or replace the low-pressure nozzle. 
Clean,  correct  or  replace  the  non-return  valve  of  the  chemical 
injector. 

 

 

For any further inconveniences, not mentioned in this user guide or any damages 
of the machine, we strongly suggest you to make contact with your dealer for the 
repair or possible replacement of any original spare-parts.
