Hydraulic Pump does Not Start

  • Check that the hydraulic pump is properly connected to the main supply.

  • Check that the hydraulic fluid level is correct.

  • Check that the power of the generator (if used) is sufficient.

  • Check that the cross section of the cable is suitable for its length.

  • If the motor does not run, remove the protective cover from the following switches to check that the switches are on:

    • Isolater switch on LHS.

    • Circuit breaker on RHS.

If the hydraulic pump still does not start, contact local Atlas Copco sales representative.

Pay attention if the working conditions are below 10˚C, or if the cable length is very long.
