When servicing a quality thermal bonding machine, take the following main safety precautions:
Before the maintenance and repair of the quality thermal bonding machine, the power supply on the PUR hot melt adhesive machine and the main power supply connected to the outside world must be cut off, and no live operation is allowed.

When carrying out disassembly, maintenance and repair work, it is best for maintenance personnel not to wear earrings, watches, necklaces, bracelets and other conductive accessories to prevent accidents.
Do not disassemble and check any parts on the quality thermal bonding machine, unless you know enough about the performance of the equipment.
Do not disassemble and repair the PUR hot melt adhesive machine alone unless there are other people assisting, and in the event of an accident, mechanical damage or personal injury, immediate help or first aid can be given.
Only qualified personnel should carry out maintenance work on the PUR hot melt adhesive machine.
Under any circumstances, do not touch any wire connectors that may be exposed to the outside world or other components with wire connections that are not loose.
Before removing or moving the protective device on the quality thermal bonding machine or replacing the components, the power supply must be cut off.
If possible, try to stand on the plastic blanket for maintenance work. Never perform maintenance work on the PUR melter on a flooded floor or in a very humid environment.
Safety gloves, goggles and long-sleeved work clothes must be worn when maintaining and repairing the quality thermal bonding machine to avoid burns on the body part by the high temperature liquid hot melt adhesive or the surface of the high temperature components.
When loosening or installing the pressure joint, it must be confirmed that the pressure of the pressure air supply for the moisture-responsive quality thermal bonding machine has been reduced to zero.
When cleaning the hot melt glue tank, avoid using fireworks or sharp hard tools to avoid scratching the Teflon non-adhesive coating of the heating plate of the PUR hot melt gluer.
If there is air pressure or the PUR hot melt adhesive machine leaks glue, do not continue to use the quality thermal bonding machine. First stop the PUR hot melt adhesive machine, cut off the power supply, and reduce the operating pressure to zero before overhauling.
