please see the included "Lombardini"
instruction manual.
• 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)
• The petrol manifold is closed;
• Engine is out of gas;
• Cold engine;
• Spark plug cable is disconnected or
damaged;
• 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 drain valve is open;
• The gaskets of the pumping group are
worn;

• 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;
