FAQ 

Q：What usually causes oil leakage of the hose assembly?
A：It is mostly caused by loose crimping, worn outer rubber, long-term fatigue aging or overpressure of hydraulic system. Stop the machine and replace it in time once leakage is found.

Q：What should be noticed during installation?
A：Do not twist the hose forcibly. Keep proper bending allowance, stay away from sharp edges and high-temperature exhaust pipe, and fix the pipeline to prevent abrasion caused by vibration.

Q：Can this hose assembly replace hoses of other part numbers?
A：Mixing use is not recommended. Hoses with different part numbers differ in length, fitting angle and pressure rating, which may lead to assembly interference and leakage.

Q：What inspection should be carried out after installing the new hose?
A：Check the tightness of fittings first. Operate boom and bucket repeatedly under no-load condition, check for leakage on fittings and hose body before heavy-load work.

Q：What is the normal service life of the hose?
A：It depends on working condition, oil temperature and pressure. Regular inspection is recommended every 1 to 2 years under heavy load. Replace immediately if cracks, bulge or hardening appears.

Q：How to store spare hoses properly?
A：Store in cool and dry warehouse, avoid sunlight and rain immersion. Do not squeeze or bend the hose for a long time, keep away from acid, alkali and oil pollution.
