Changing the Hydraulic Oil

It is recommended to change the hydraulic oil after 750 operation hours or after one year depending on what occurs first.

  1. Remove the oil cap from the top of the oil filling tube.

  2. Loosen the plug at the bottom of the tank by using the allen key.

  3. Put back the plug after draining the oil.

If the oil has a dark color, any traces of foam or particles, change both the oil and the filter immediately. Otherwise, the pump could be damaged.

Pay attention to the characteristics of the oil. In case of doubt, contact local Atlas Copco sales representative to avoid using the wrong oil.
