OPERATION
The Melt Bolt should be fully retracted during operation start up. When the plastic
reaches a melted state, the melt bolt can be immersed. Turn the adjusting screw
clockwise to extend the tip, turn the screw counter-clockwise to retract the tip. The
graduated markings are spaced at 1/8” intervals allowing for easy repeat sensor
placement. Retract the melt bolt completely before allowing the melt stream to
cool. Forcing the screw may result in damage to the sensor.
