Step 1: Bleed the hydraulic system: 

Pull up the pump lever and turn it clockwise to 
open the drain valve. 

When the lifting arm is fully lowered, pump seve-

Place the floor jack on a level and firm surface 
and place the front part of the floor jack at least 
500 mm higher than the end part of the floor jack
