After flushing the system, follow this procedure to adjust the pressure
control valve on units with a gear pump. To determine which kind of

Operation
section of this manual.
1. If the pump is turned on, turn it off by pressing the PUMP key. The

NOTE:
This setting will work well for most applications. For some
applications, however, you may want to adjust the setting to increase
or decrease the pressure at which the valve opens to return adhesive
to the tank. Adjust the valve by turning it clockwise to increase
system pressure or counterclockwise to decrease system pressure.
