Hydraulic oil leakage is a significant symptom of serious underlying issues, like weak digging force and slow-moving/working.
If you find there is little oil stain/oil ring on the cylinder or the accumulation of dust or impurities on the cylinder rod, that means you are facing the problem of a leaking oil cylinder or a bad seal.
Some people will overlook this issue because they don’t think that there is severe damage, and the excavator is working fine at that moment. However, by leaving this problem with a little oil leakage, you’re pulling dirt and dust right back up into the cylinder itself. This will result in the contamination of the whole hydraulic oil system, which will lead to more expensive maintenance/repair costs.
Thereby, repairing the excavator before more components get damaged.
