The cylinder and pressurized cylinder maintenance and maintenance guidelines:

A, when replace hydraulic oil?
1 and when the oil tube marking the hydraulic oil into the milky white or black, please replace hydraulic oil.

Second, when gas?
1 and when pressurized cylinder in origin, and oil pipe display non-standard actual oil than oil lines within the scope of the hydraulic oil, please.

Third, how to cheer?
1 and pressurized cylinder to origin.
2, shut off the power.
3, unplug pressurized cylinder, and atmospheric carbon monoxide B trachea.
4 and the oil cylinder on top, clean mouth bulkhead spin on hole threads, funnel, and cheer re-fuelling valve to oil lines range.
5, will add seal tapes, blocking the loads on hole.
6 and inserted B intake trachea.

Fourth, how to replace hydraulic oil?
1 and pressurized cylinder to origin.
2, shut off the power.
3, unplug pressurized cylinder, and atmospheric carbon monoxide B trachea.
4 and prepare the plastic, plastic tube placement storage at the bottom.
5 oil cylinder, dumping bottom mouth bulkhead unscrew.
6, let oil free flow and clean.
7 and clean oil, clean oil hole threads, will add seal tapes, blocking the loads oil hole.
8 and unscrew re-fuelling valve cone top oil, clean gas hole threads loads, funnel, re-fuelling valve refueling
Add to the oil lines range.
9 and inserted B intake trachea.

Five, replace hydraulic oil type?
1, 68 # anti-wear hydraulic oil
2, 46 # anti-wear hydraulic oil

Six, but why the many oil?
According to the order of reason, please side:
1 and 3 combination of oil mist, drops of oil, the big opening regulator to the minimum.
2 and when pressurized cylinder to position, and oil origin marking tube showing the actual oil above or below the oil lines range.
3 and pressurized cylinder surface damage caused by hydraulic packings, somewhere overflows.
4 and pressurized cylinder seals, causing damage from electromagnetic valve ejective hydraulic oil.
5 and pressurized cylinder cylinder, causing damage from electromagnetic valve ejective hydraulic oil.
6 and the hydraulic oil emulsion or severe wear.
Note: if the liquid is ivory is water, it from the filter or pipeline. Please pay attention to distinguish!
