8.7.2 Impurities in oil

* Oil storage and transport containers will increase the dirt.
*Due to wear and tear of components crane operations generate metal and other particles that
come in the hydraulic system.
* When repairing the crane the dirt gets into the system.
* Upon component damage large quantities of impurities at the time may get into the cycle.
* Impurities in the hydraulic oil cause components to wear faster than normal, temporary failures,
such as blockages in the oil channels or jamming of the valve stems, and, at worst, component
damage.
