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)
• On/Off switch disconnected;
• Lack of gasoline;
• 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;
• Product output valve closed;
• 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.
•
Ensure the On/Off switch is on the
“on” position and turn clockwise the
pressure control knob;
•
Add gasoline;
•
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
);
•
Open the product output valve;
•
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.
Check the packing nut is tight in order to avoid
wastes but not excessively to prevent the piston
from seizing and the gaskets from wearing.
