• The equipment does not start
The equipment does not suck the
•

The equipment sucks but does
•

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)
