bench.

height.
5. With the help of an assistant place jack back onto the floor and tilt on its
front wheels. Rotate the release handle to the lowering position.
6. Ensure the lift arm returns to the fully lowered position.
7. Place jack on the floor and recheck the oil level, Refill to 6mm below the fill port if required before replacing
the filler bung as per step 1.
8. If the issue persists, please repeat steps 2 to 6.
At this point both the Pump and Lift Ram should be free of air and the Jack ready for operation. If the pump still
feels spongy or load is slow to raise, seek the services of a qualified Hydraulic repairer.
The TradeQuip range of Garage Jacks use ISO46 Grade Hydraulic Oil for the correct operation and compatibility with the seals
used in their construction.
