Setup In Minutes!
QuickJack is very easy to set up, even if you've never purchased a car lift or worked with hydraulics before. Most components come pre-installed. All you have to do is wrap some thread seal tape, wrench on some fittings and pressurize the secondary air cylinder. The entire lift assembly is delivered in three boxes: two boxes for the frames and one for the power unit. The third box also contains the hoses, lifting blocks and fittings. All you need to supply are the tools and ATF for the power unit.
Lay out the contents of your three boxes
Lay out the frames, parts assembly, power unit and hoses on a clear surface, so you don’t misplace or lose any parts during setup.
Prepare and tighten fittings
The frame assembly, hoses and power unit have some fittings that may need thread seal tape. A quick wrenching will secure and tighten the fittings.
Pressurize air cylinders
One air cylinder on each frame needs to be pressurized. They will rarely need to be pressurized again. A hand/foot pump or air compressor will accomplish the job in no time.How QuickJack air cylinders work
Set up power unit and fill with hydraulic fluid
Ensure the power unit fittings are secure, then funnel in 2.5 quarts of hydraulic oil or ATF fluid (not included).
Final checklist before lift
A few final tasks remain: drain the extra packing oil, ensure the frames are lifting correctly and a final safety inspection.Go to Operation
How do the Air Cylinders Work?
Each QuickJack frame contains a hydraulic cylinder and an air cylinder. To understand how the QuickJack air cylinders operate, it is first important to understand how the power unit works in conjunction with the frames. Note: QuickJack does not require the use of an air compressor to operate. The air cylinders can be easily charged with any portable hand pump, bike pump or foot pump that has a Schrader valve hose attachment.
How QuickJack lifts
Two independent hydraulic cylinders do all the heavy lifting. When you press Up on the pendant control, 2.5 quarts of ATF travel from the power unit's reservoir to the cylinder. A flow divider ensures pressure is equally distributed to both frames for a nice, even lift. As hydraulic fluid pressure is built, QuickJack is able to lift vehicles up to 3,500, 5,000 or 7,000 pounds, depending on which model you purchase.
How QuickJack lowers
Each hydraulic ram uses the weight of a vehicle to help the frame descend smoothly. After your vehicle's wheels touch the ground, there's no longer significant pressure on the cylinder to help it close. This is where the integrated air cylinder comes in.
During the final stages of the frame's descent, the air cylinder releases air pressure up to 50 psi against the hydraulic ram. This continues until the hydraulic cylinder is fully closed. Once you decide to extend the cylinder and raise the frames, air is forced back into the air cylinder tank. Because the air is kept inside the air & hydraulic cylinder structures, there's no need to recharge the air cylinder after the initial charge. You might only need to refill it once or twice over the course of many years of ownership, depending on how many times you use QuickJack throughout the year.
