Always close the air compressed supply and unload the plant pressure before performing any check or replace-
ment of pump parts (see "correct procedure of decompression").
PROBLEMS AND SOLUTIONS
Solution
Cause
Problem
• The equipment does not start
• The equipment does not suck the
product
• The equipment sucks but does not
reach the pressure desired
• When pressing the trigger, the
pressure lowers considerably
• The pressure is normal but the
product is not atomized
• The atomization is imperfect
• When releasing the trigger of the
gun, the equipment does not stop
(the motor runs slowly and the
piston rod keeps on going up and
down)
• Lack of voltage;
• Considerable drops in mains voltage;
• On/Off switch disconnected;
• Breakdown of pressure transmitter;
• Breakdown of motor electric control box;
• The line of material coming out of the
pump is already under pressure;
• The product is solidified inside the
pump;
• Suction filter clogged;
• Suction ilter too fine;
• The equipment sucks air;
• Lack of product;
• The equipment sucks air;
• The recirculating-safety valve is open;
• The gaskets of the pumping group are
worn;
• Suction or delivery valve dirty;
• Nozzle too big or worn;
• The product is too dense;
• The filter of the gun-butt is too fine;
• The nozzle is partially clogged;
• The product is too dense;
• The filter of the gun-butt is too fine;
• The nozzle is worn;
• The gaskets of the pumping group are
worn;
• Suction or delivery valve dirty;
• Recirculating-safety valve defective;
• Check the correct connection to the
power supply;
• Check the extension cable;
• Ensure the On/Off switch is on the
“on” position and turn clockwise the
pressure control knob;
• Verify and replace it, if necessary;
• Verify and replace it, if necessary;
• Open the drain valve to release
pressure in the circuit;
• Open the drain valve to release
pressure in the circuit and stop the
machine. Disassemble the pumping
group and the pressure transmitter
and clean;
• Clean or replace it;
• Replace it with a larger-mesh filter
(with very dense products, remove
the filter);
• Check the suction pipe;
• Add the product;
• Check the suction pipe;
• Close the recirculating-safety valve;
• Replace the gaskets;
• Disassemble the pumping group;
• Replace it with a smaller one;
• Dilute the product, if possible;
• Replace it with a larger-mesh filter;
• Clean or replace it;
• Dilute the product, if possible;
• Replace it with a larger-mesh filter;
• Replace it;
• Replace the gaskets;
• Disassemble the pumping group and
clean;
• Verify and replace it, if necessary;
