AL-KO AL-KO IQ7 Bleeding the Hydraulic System, IQ7 Bleeding the Hydraulic System Operating instructions

  • Hello! I have carefully read the provided document regarding the AL-KO iQ7 Pressure Bleed Gun. This manual provides comprehensive instructions for bleeding your hydraulic brake system. It outlines the necessary steps, from filling the reservoir to operating the bleed gun and ensuring proper brake function. I'm familiar with the key features and warnings, and I'm ready to answer any questions you might have.
  • How do I fill the reservoir with brake fluid?
    How do I ensure there is no pressure in the system before removing the pressure bleed gun?
    What should I do if air has entered the hydraulic system?

3. Screwthelidinplacetosecurethesocket.
4. DonotpushonwithexcessiveforceordamagemaybecausedtothereservoirortheOringonthepressurebleedgunsocket.
5. Placetheotherendofthebleedguntubeintoabottleorcontaineroffresh,newbrakeuid(seediagram2).
6. Openthebleedscrew(startwiththefurthermostcalliper)atleastonefullturn.Placeaclearexiblehoseoverthebleedscrew
andimmersetheotherendintoacontainerpartiallylledwithbrakeuid.
7. Squeezethepressurebleedgunrepeatedly(seediagram3-butnottoofastorcavitationsmayoccur)ensuringthatthebulk

8. Continuesqueezingthepressurebleedgununtilthebrakeuidintheexiblehoseattachedtothebleedscrewisfreeofair
bubbles and tighten the bleed screw.
9. Repeattheprocesswiththenextfurthermostcalliperawayfromtheactuator.
10. Bleedtheothersideofthetrailerstartingwiththeclosestcallipertotheactuatorrstasabove.
11. Connectthetrailertothetowvehicleandturnonignitiontoactivateactuator.Allowthecompressortofullychargethe
actuator(approx90seconds).Oncethecompressorhasstoppedapplythebrakes,andholdonfora5secondperiodand
release.Repeatthis4times.
12. Checkthebrakeuidlevelinthereservoir.Itshouldnotexceedthetopofthesightglassmaximumlevel.
13. Replacetheuidreservoircap.
IMPORTANT
Before removing the pressure bleed gun from the reservoir, make sure that there is no pressure in the system (pressure bleed
gun has fully returned to the rest position) or brake uid spillage will occur causing paint damage.
