1、胶管及胶管总成只能用于输送所设计的物料，否则会减少使用寿命或失效。

1. The rubber tube and hose assembly can only be used to transport the materials designed, otherwise the service life or failure will be reduced.

2、正确使用胶管的长度，胶管在高的压力下长度发生变化（-4%-+2%）以及机械运动引起的长度变化。

2. The correct use of the length of the hose, the length of the hose under high pressure (-4%-+2%) and the change of length caused by mechanical motion.

3、胶管及胶管总成不应在超过设计工作压力的压力（包括冲击压力）下使用。

3. The hose and hose assembly should not be used under pressure of design work pressure (including impact pressure).

4、胶管及胶管总成所输送的介质温度正常情况下，不应超过-40℃-+120℃，否则会减少使用寿命。

4, the medium temperature of the rubber tube and the hose assembly should not exceed -40 C -+120 C under normal temperature, otherwise the service life will be reduced.

5、胶管及胶管总成不应在小于胶管最小弯曲半径下使用，避免在靠近管接头处发生弯曲或折曲，否则会阻碍液压传递及输送物料或损坏胶管组合件。

5, rubber hose and hose assembly should not be used in less than the minimum bending radius of hose, avoid bending or bending occurs near the pipe joints, otherwise it will hinder the hydraulic transmission and material damage or conveying hose assembly.

6、胶管及胶管总成，不应在扭转状态下使用。

6, rubber tube and hose assembly, should not be used in the torsional state.

7、胶管及胶管总成应小心搬运，不应在锋利和粗糙的表面上拖拽，不应折曲和压扁。

7, rubber hose and hose assemblies should be carefully handled, should not be in sharp and rough surfaces should not drag, bending and flattening.
