1. Avoid using pur hot melt glue machine around volatile and explosive raw materials or gases, and do not store flammable and explosive materials around the spraying equipment of PUR hot melt glue machine.

2.没有适当的保护装置，没有良好的绝缘体或保护面板，不要使用热熔胶机。

2. Do not use hot melt adhesive machine without proper protection device, good insulator or protection panel.

3.pur热熔胶机需要维修时，须经过培训人员的培训后才能拆卸维修。

3. When the pur hot melt adhesive machine needs to be repaired, it can be disassembled and repaired only after the training of professional training personnel.

4.当环境温度低于- 20℃或环境温度高于80℃时，pur热熔胶机不能运行。

4. When the ambient temperature is lower than - 20 ℃ or higher than 80 ℃, PUR hot melt adhesive machine can not run.

5.使用pur热熔胶机时，不能有快速流动的空气。当pur热熔胶机使用的pur胶筒和胶水压板暴露在循环快的空气中时，pur热熔胶机的热熔胶流量会因快速冷却而受到影响，能量会被浪费。

5. When using pur hot melt adhesive machine, there should be no fast flowing air. When the pur glue cylinder and glue pressing plate used in pur hot melt glue machine are exposed to the air with fast circulation, the hot melt glue flow of PUR hot melt glue machine will be affected due to rapid cooling, and the energy will be wasted.

6.使用pur热熔胶时，检查pur热熔胶桶是否变形，丢弃变形严重的pur热熔胶桶，以免损坏pur热熔胶机压板。

6. When using pur hot-melt adhesive, check whether the pur hot-melt adhesive barrel is deformed, and discard the severely deformed pur hot-melt adhesive barrel to avoid damaging the pressing plate of PUR hot-melt adhesive machine.

7.每当拆卸PUR热熔胶机的喉咙,喷胶枪,试图穿过清洁剂清洗拆卸和维修之前,不能清洗,须使用高温硅油在很短的时间内将面临设备喷嘴或软管接口密封,避免湿固化反应。

7. Whenever the throat and spray gun of PUR hot-melt adhesive machine are disassembled and cleaned with cleaning agent, it cannot be cleaned before disassembly and maintenance. High temperature silicone oil must be used to seal the nozzle or hose interface of the equipment in a short time to avoid wet curing reaction.
