During installation, the PUR hot melt glue machine should not be placed in well-ventilated conditions or environments with fast-moving air. Rapid airflow can cause the adhesive sprayed by the hot melt glue nozzle assembly to cool rapidly, leading to stringing and affecting the adhesive quality.

The PUR hot melt glue machine should not be operated when the ambient temperature is below -20 degree or above 80 degree .

Ensure there is no fast-moving air in the environment where the PUR hot melt glue machine is used. Exposing the PUR adhesive barrel and glue pressure plate to fast-moving air will affect the hot melt glue flow of the PUR hot melt glue machine due to rapid cooling, resulting in energy waste.
