Purity and filtering of the hydraulic fluid
Fine contamination can significantly impair the function of the hydraulic component. Contamination can cause irreparable damage.
Examples of fine contamination include:
– Metal chips
– Rubber particles from hoses and seals
– Dirt due to assembly and maintenance
– Mechanical debris
– Chemical ageing of the hydraulic fluid
NOTE
New hydraulic fluid from the manufacturer does not necessarily have the required level of purity.
The hydraulic fluid must be filtered during filling.
Pay attention to the cleanliness level of the hydraulic fluid to maintain faultless operation.
(Also see cleanliness level in
