QuickJack™ Portable Car Jack 31 P/N 5900263 — Rev. B1 — September 2021
Bleeding the Hydraulic Cylinders
Bleeding the Hydraulic Cylinders removes air from the Hydraulic System.
If you have air in the Hydraulic System, you can experience shaking, jerking, one frame rising faster
than the other, and so on during raising and lowering. This does not damage the QuickJack or the
Hydraulic Cylinder, but it is not the normal smooth experience you should be getting.
To bleed the Hydraulic Cylinders, you are going to need:
• multiple
rags to wipe up fluid
• a
3/16 " hex key (also called an Allen® key) to loosen and tighten the Bleeder Screws
•
six of the Lift Blocks that came with the QuickJack: four Tall and two Medium
Do
not put a Vehicle on the QuickJack Frames when bleeding the Hydraulic Cylinders.
Important In general, you should
never raise your QuickJack Frames without weight. However,
for bleeding the Hydraulic Cylinders, we recommend
not adding weight to the
QuickJack Frames.
Do not raise beyond the First Locking Position without
weight!
To bleed the QuickJack’s Hydraulic Cylinders:
1. Lay the two QuickJack Frames next to each other on the ground.
⚠ CAUTION Keep hands clear of pinch points at all times; you could be injured.
2. Stack two of the Tall Lift Blocks on each other, and then put one of the Medium Lift Blocks on top
of them. Do this twice, so you have 2 sets of three stacked Lift Blocks.
3. Raise the Wheels end of the QuickJack Frames, one Frame at a time, and put one set of stacked
Lift Blocks under the Flat Plate that is under the Bleeder Screw.
⚠ CAUTION Do not put the stacked Lift Blocks under the Wheel end of the Frame. The Wheel
end of the Frame moves when the QuickJack is being raised or lowered, which
could lead to the stacked Lift Blocks falling over.
4. Gently rock each QuickJack Frame to make sure it is stable on the stacked Lift Blocks.
