Issue
Action to Take
Frames do not go up or
down.
Make sure the Power Unit is getting appropriate power; if not, check
the circuit breaker. Make sure none of the Hydraulic Hoses are
pinched or leaking. Make sure there is sufficient Hydraulic Fluid in the
Fluid Reservoir. Bleed the cylinders.
Frames do not come down.
Make sure there is a Vehicle on the Frames
; if not, add one
(the QuickJack is designed to work with weight). Check the pressure in
the Air Cylinders; inflate to 40 to 50 PSI, but do not exceed 50 PSI.
Frames are stuck at full
height with no weight.
QuickJack Frames require weight to come down from a fully raised
position. Refer to
Frames at Full Height with No Load
Frames do not rise from a
zero net rise position.
QuickJack Frames cannot raise a full load from a completely flat
position. Refer to
Vehicle with No Tires Fully Lowered
Hydraulic Fluid is dirty.
Replace the dirty Hydraulic Fluid with clean fluids.
Jack makes odd noises
Lubricate hinge points using white lithium grease.
Frames lower without using
the Pendant Control.
Make sure the QuickJack is engaged on a locking position (if it is not,
the Frames will slowly lower).
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 release it, hold
Down
on the Pendant Control for ~5 seconds
after
the Frames
reach the ground, allowing as much Hydraulic Fluid as possible to
return to the Fluid Reservoir.
Frames stop raising before
reaching the Top Locking
Position
There is not enough Hydraulic Fluid in the reservoir. Return the
QuickJack Frames to the ground, then add fluid to the reservoir to
.5 inch below the fill hole.
No pressure from pump.
Prime the pump.
