Emptying the tank

tank directly without passing the adhesive through the pump system.
In order to do this the following indications must be followed:
1 Maintain the tank at the operating temperature.
2 Remove the side shroud cap.
3 Lower the emptying chute located next to the tank and put an
appropriate container in place.
4 Unscrew the plug and allow the adhesive to flow freely into the
container.
