Troubleshooting
This section describes how to troubleshoot your QuickJack.
Note: If your QuickJack is not functioning correctly, you
must take it out of service until it is fixed.
Important: All repair work
must be done by qualified personnel.
Issue Action to Take
Frames do not go up or
down.
Make sure none of the Hydraulic Hoses are pinched or leaking. Make
sure there is sufficient Hydraulic Fluid in the Fluid Reservoir. Make sure
the Power Unit is getting appropriate power. Bleed the cylinders.
Frames do not come down. Make sure there is weight on the Frames; if not, add some (the
QuickJack is designed to work with weight on the Frames). Check the
pressure in the Air Cylinders; inflate to 40 to 50 PSI, but do not exceed
50 PSI.
No pressure from pump. Prime the pump.
Frames are stuck at full
height with no weight.
Your QuickJack requires weight to come down from a fully-raised
position. Refer to
Frames at Full Height with No Load
for
assistance.
Frames do not rise from a
zero net rise position.
Your QuickJack requires a little bit of space to get going to raise a
load. It cannot raise a full load from a completely flat starting position.
Refer to
Vehicle with No Tires Fully Lowered
for assistance.
Hydraulic Fluid is dirty. Replace the dirty Hydraulic Fluid with clean, approved ATF fluids, such
as Dexron III, Dexron, VI, Mercon V, Mercon LV, or comparable.
Jack makes odd noises Lubricate hinge points using white lithium grease.
Frames are slowly lowering
without using the Pendant
Control.
Make sure the QuickJack is engaged on a locking position (if not,
Hydraulic Fluid leaks out slowly, lowering the Frames).
Only leave the
QuickJack on the ground or on one of its two locking positions
.
Air Cylinder is not holding
pressure.
Make sure the valve core inside the valve stem is tightly in place; that
is, it is not letting air escape. You can use a standard valve tool to
check. Do not overtighten the valve core.
Quick-Connect Fittings
becoming increasingly
difficult to connect.
Pressure is building up in the hydraulic system. To prevent this, hold
the
Down
button on the Pendant Control for several seconds
after
the Frames reach the ground, allowing as much Hydraulic Fluid as
possible to return to the Fluid Reservoir. If the pressure buildup is so
great you cannot connect the fittings, contact QuickJack support.
