Smart Start/Soft Start Operation
Smart Start
Sprayer will start under the following
conditions:
•
A new sprayer is plugged in and ON/OFF
switch is turned ON.
•
Gun is triggered and air control valve is
open far enough.
•
There is a small leak in the system and
the pressure drops below the pressure
switch setting. This may appear to be
random operation.
•
When a bleeder gun is used.
•
When the pressure is relieved by
triggering the gun while the sprayer is
OFF and then turned back ON.
•
Prime valve is opened.
•
There is a hose failure (leak) in the twin
line hose.
Soft Start
•
The easiest way to tell if the Soft Start
System is functional is to spray material.
•
The system is operating properly when a
small amount of material initially comes
out of the gun when triggered and the
volume of material slowly increases to
full spray.
NOTE: Motor runs when gun is triggered.
Sprayer is designed to stop pumping when
gun trigger is released.
