10.2.2 Checking and maintenance intervals
for the hydraulic hose assemblies (workshop job)
• prior to the initial operation
• after the first 10 hours of operation
• very 50 hours of operation (at least 1/2 a year)
Check the hydraulic hose assemblies, e.g.
• check all parts of the hydraulic system for leakages
• Retighten bolt connections to remedy leakages.
• Check hydraulic hoses for damage (kinks, cuts and abrasion)
• Check whether the hose casing is brittle
• Check hoses for deformation (bubbles, buckling, squeezing, separation of layers)
• Check the appropriate fitting of the hoses
• Check the hose for firm seating in the fitting
• Check connecting fitting for damage and deformation
• Check for corrosion between connecting chest and hose
• Do not exceed the permissible period of use
Replace the hydraulic hose assembly after a use of max. 6 years (including a
possible storing period of 2 years maximum).
Important!
Remedy any faults immediately when noted.
The maintenance of the checking intervals should be recorded by the operator.
Also during operation check hose casings of the hydraulic hose assemblies for
damage (kinks, cuts, abrasion).
Replace the hydraulic hose assembly after a use of max. 6 years (including a
possible storing period of 2 years maximum).
