© 200424 3-3 Inspection and adjustment HYDRAULIC LIFTING GEAR ΧΦ65/75/85 series 8 9 5. Turn the adjusting bolt (1) using an Allen key. During the adjusting process the trailing axle should not be activated. - Screwing the bolt in will increase the pressure. - Unscrewing the bolt will decrease the pressure. Turn the adjusting bolt (1) using small steps of not more than 20 . Measure the pressure after each step. Note: As the pressure increases very rapidly, a large turn of the adjusting bolt can result in excessive system pressure causing damage. 6. Lift the trailing axle and take the pressure reading. Release the control switch on the dashboard immediately once the maximum pressure is achieved. If the pressure exceeds 200 bar, the control switch on the dashboard should be released immediately. 7. If the measured value is still incorrect: connect the pressure-switch connector and lower the trailing axle. 8. Turn the adjusting bolt (1) once again. 9. Remove the pressure switch connector. 10. Wait for approx. 2.5 minutes and take a new reading. If necessary, repeat points 7 to 10 until the pressure setting is correct. 11. Tighten lock nut (2). Make sure that the adjusting bolt (1) does not turn too. 12. Connect the connector of the pressure switch, lower the trailing axle and check the pressure again. 13. Remove the T-piece and pressure gauge. 14. Check the oil level in the reservoir and top up if necessary. 1 2 3 A8 00 279 1 2 3 A8 00 279 |
