OPERATION
RAISING A LOAD
WARNING! Do not place any part of your body under the load without jack
stands in place. The floor jack is not designed to maintain heavy loads for
long periods of time
1. Place the jack on a hard level surface capable of handling the load.
2. Twist the handle to the right to close the release valve.
3. Pump to raise the ram. Stop just before the ram contacts the load’s lift
point. Inspect the ram’s position and adjust if necessary.
4. Pump slowly until the ram is supporting the load. Continue to pump as
normal to lift the load to the desired height.
5. Position supports like jack stands if the load will remain off the
ground for an extended period. Consult the support device’s manual
for proper placement.
LOWERING A LOAD
WARNING! Dynamic shock loads are created by quick opening and closing of
the release valve when lowering the load. The resulting overload may cause
the hydraulic system to failure, which could result in severe personal injury
and/or property damage.
WARNING! Before lowering the load or vehicle, ensure that there are no
obstructions underneath and that all people are standing clear.
1. Open the valve by gradually twisting to the left.
2. The load will begin to lower.
3. Twist right to slow and left to increase the rate of descent.
4. Remove the jack once the load is on the ground or a support mechanism
like jack stands.
5. The ram should fully retract. If it does not, push down on it until it
is seated.
