Routine inspection

Inspections should be detail-oriented and all problems found must be handled in time.

1. Inspection must be made to the rubber hose after each operation, to make sure no structural damage occurs.

2. Hydraulic test is recommended, if the rubber hose is subject to large pressure in the operation or the extremal surface of rubber hose is in long-time contact with media delivered.

3.Please release the rubber hose from pressure when it is not in use, which may extend its service life.

4. Regular inspections should be made for wear, hardening, softening, color change, aging and other abnormal conditions.

5.Please cease operation and have the rubber hose replaced if any of the following condition occurs: Local extension or expansion is found at the connector area; or theinnerandouterlayers are detached from each other; or crack is found on the external surface or there is water invasion at the wire layer, or any other significant change.

Maintenance

The oil tank should be refilled with hydraulic oil after the machine is started, to make the oil level at the upper limit of observation window and to make sure normal circulation along the hydraulic oil pipeline.

1.Comprehensive analysis.Testing instruments should be used to measure main performance indicators and to take continuous monitoring over oil quality.

2.Regular replacement of hydraulic oil.Hydraulic oil should be replaced on regular basis according to run hours of the hydraulic system.

3.Experience based determination.Visual inspection and comprehensive analysis is made by sampling and comparing the hydraulic oil with new oil. Visual inspection is made to hose for damages or wear and replacementif severe corrosion is found.
