Instructions and Maintenance
De-aerating
Fig. 5
•
Air bubbles may penetrate in the vehicle lifting jack
hydraulic system and impair its functioning (heavy run,
jerky lifting/start up)
•
Close the bleeding valve (Fig. 1/Pos. 8) completely.
•
Using a pump, lift the jack up completely.
•
Open the bleeding valve (Fig. 1/Pos. 8) and push the
