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)
