  • Page 45: Adjustment

    If the deviation exceeds 3%, the display will show error code 16 See Error messages on page 72. If the same error code persists after further readings, replace one of the potentiometers. Differences in the elevation between the two posts can arise through temperature differences, elastic compression and slight internal leakage in the system.

    When working, the temporary mains power connection can be disconnected, and the cable channels fastened using spacer bushings, screws and rings. Cylinder bleeding The cylinders are fitted with an SW10 nipple for bleeding air at the top. While raising, turn the nipples once round to loosen them and wait until there is a constant flow of oil without air bubbles.

  • Page 54: Inspection And Maintenance

    Inspection and maintenance Aim of maintenance Maintenance can be divided into two categories: • Preventive maintenance. • Corrective maintenance. Preventive maintenance is necessary to keep the machine in a good condition or returning it to that condition. Corrective maintenance is done after malfunctions have occurred.

  • Page 55: Pay Attention To Safety

    9.2.1 Pay attention to safety When carrying out inspection and maintenance, always set the Freedomlift to the lowest position and switch off the mains power supply switch (position 0). Secure the switch using a padlock. If the Freedomlift is in a higher position, always lower it into the safety lock. Always pay attention to safety.

  • Page 56: Waste Disposal

    9.2.3 Waste disposal Remove and dispose in a correct manner lubricating agents, used chemical products and other such matter. On this subject, the local environmental recommendations should be respected. See also Disposal on page 16. 9.2.4 Forms and administration It is recommended to keep a record for each periodic maintenance procedure performed on your equipment.

  • Page 58: Replacing Hydraulic Oil

    Do not attempt to apply oil or grease to any component not mentioned in a maintenance procedure or schedule. Contact your supplier/dealer if you discover an irregularity with the lubrication of any part. Replacing hydraulic oil Replace the hydraulic oil in the tank approximately once every 2 years. Set the Freedomlift to the lowest position and drain off the oil.

  • Page 59: Cleaning

    The different types of oils should not be mixed. After draining the oil from the lift and refilling the system with new oil, a low mix percentage is allowed. Do not attempt to apply oil or grease to any component not mentioned in a maintenance procedure or schedule.

    Services It is not necessary to remove the vehicle from the vehicle lift to resolve most malfunctions. However, it is strongly recommended that you do remove the vehicle if the vehicle lift is in the lowest position. Set the vehicle lift to its lowest position in the event of malfunctions or repairs. If the malfunction makes this impossible, then ensure that all pawls are engaged in the safety locks (lower without unlocking).
