Cause
Problem
•
The equipment does not start
•
The equipment does not suck the
product
•
The equipment suck 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.
Leakage from the seal-tightening
screw
•
The atomization is imperfect
• Lack of voltage;
• Considerable drops in mains voltage;
• ON-OFF switch disconnected;
• Setting valve faulty pressure;
• Breakdown of motor electric control
box;
