TROUBLESHOOTING
•
The pump does not work
•
The operation of the pump is ac-
celerated and without pressure
•
The pump works but it does not
stop when the chamber is full (the
pumping unit slowly moves up
and/or down)
•
By pressing the gun trigger, the
pressure of the product highly
decreases
• feeding air is not sufficient.
• Product outlet line is clogged;
•
Product inlet line is clogged;
•
Pneumatic motor is blocked in the
position of cycle inversion;
•
Some components of the pneumatic
motor are damaged ;
• The product is lacking;
• The pump is sucking air;
•
The gaskets of the pumping rod are
worn;
•

outlet are too thin
• Check the air supply line. Increase
the diameter of the feeding air pipe;
• Open the recirculation nozzle and
check that the pump starts. unscrew
the high pressure filter and clean and/
or replace the filter sieve. Clean and/
or replace the gun filter;
•

Before performing any inspection or replacement of the pump components, make always
sure to close the compressed air supply and discharge the residual pressure in the circuit.
