8.10.6 Hydraulic Hoses Inspection
Note！
 If hydraulic pump, pipes and joints are damaged because of mechanical
effect, heat effect or other effect, that should be changed.
 Keep pipes, tubes and hoses a long enough distance away from hot
engine parts (exhaust system), and make sure there’s no friction.
Keep hydraulic hose stored in a dry place to avoid sunlight and ultraviolet rays.
Hydraulic tubes should be checked by after-sale engineer at least every year. Regularly check
hoses for leakage. During visual inspection, even if only found tiny damage, hoses should be
changed immediately.
Possible damage of hoses:
 Sliding joint in the hose.
 Outer layer damage, cut and abrasion (any exposure of enhancement layer)
 Hose harden, chap and burn.
 Crack, damage and serious corrosion on joints.
 Leakage of joints or hoses.
 Hoses twine, broken, flattening and twist.
 Hoses outer layer deformation and soft.
Other items for daily inspection:
Tighten, repair or change following as requirements.
 Oil leakage
 Clogging
 Pipe clamp, cover and protective objects.
 Over storage time and service life.
