What to do if QuickJack Jacks frames do not go up or down?
If the QuickJack Jacks frames do not go up or down, check the following: Ensure the power unit is receiving adequate power, and if not, inspect the circuit breaker. Verify that none of the hydraulic hoses are pinched or leaking. Confirm there is sufficient hydraulic fluid in the fluid reservoir. Finally, bleed the cylinders.
What to do if QuickJack Jacks frames do not come down?
If the QuickJack Jacks frames do not come down, ensure there is a vehicle on the frames, as the QuickJack is designed to work with weight. Also, check the pressure in the air cylinders, and inflate them to between 40 and 50 psi, without exceeding 50 psi.
How to troubleshoot QuickJack 3500SLX frames that won't go up or down?
If your QuickJack Jacks frames aren't moving, start by checking if the Power Unit is getting power; if not, check the circuit breaker. Ensure none of the Hydraulic Hoses are pinched or leaking. Make sure there's enough Hydraulic Fluid in the Fluid Reservoir. Finally, bleed the cylinders.
Why are my QuickJack 3500SLX frames lowering without using the pendant control?
If your QuickJack Jacks frames are lowering on their own, it means the QuickJack is not engaged on a locking position. When it's not properly locked, the frames will slowly descend.
What to do if QuickJack 3500SLX frames won't lower with a vehicle?
If your QuickJack Jacks frames won't lower to the ground with a vehicle on them: * Check the pressure in the Auxiliary Pneumatic Spring and inflate it to between 40 and 50 psi, but do not exceed 50 psi. * Verify power is being supplied to the QuickJack. * Verify the down Solenoid Valve is functioning.

If the Hydraulic Fluid in your QuickJack Jacks is dirty, replace it with clean fluid.
Why are my QuickJack 3500SLX frames stuck at full height with no weight?
QuickJack Jacks frames need weight to come down from a fully raised position. Refer to Frames at Full Height with No Load.
What to do if the air cylinder in QuickJack Jacks is not holding pressure?
If the air cylinder in your QuickJack Jacks is not holding pressure, check the valve core inside the valve stem. Make sure it is tightly in place and not allowing air to escape. Use a standard valve tool to check, but do not overtighten the valve core.
Why are my Quick-Connect Fittings on my QuickJack Jacks becoming increasingly difficult to connect?
The difficulty in connecting Quick-Connect Fittings on your QuickJack Jacks is due to pressure building up in the hydraulic system. To release this pressure, hold the 'Down' button on the Pendant Control for about 5 seconds after the frames reach the ground. This allows as much hydraulic fluid as possible to return to the fluid reservoir.
