Flushing - general
Changing a component
!
Caution
Always flush the complete oil circuit after
you have replaced a component.
Solid particles in the circuit will very quickly
cause damage to machine components.
Fig. 1
Effect of contamination
Coarse particles (> 15 µm)
Sudden failure of components.
Fine particle contamination (5 – 15 µm)
Wear of components, internal leaks, inaccurate
controlling behaviour, blockage of valves.
Extra fine particle contamination (< 2 – 5
µm)
Silting of oil, accelerated aging of oil, corrosion.
Water in oil
Increased wear, accelerated aging of oil.
Chips (abrasion) in the oil
l
Open and clean all components in the oil
circuit, replace if necessary.
l
Clean all high pressure hoses in the oil cir-
cuit, replace if necessary.
l
If abrasion is found in the travel circuit you
should also flush the vibration circuit.
