Raising and Lowering Vehicles
Keep the following in mind when operating your Lift:
• Be safe. Make sure to check for people, pets, and objects that might be in the path of the Lift as you
raise or lower it. If there is something in the way, stop the Lift and move it out of the way. Watch the Lift
carefully as it raises and lowers.
⚠ DANGER Pay careful attention when you are raising or lowering your Lift. If a person or pet
becomes stuck under the Lift, they could be injured or, in rare cases, killed.
• The Power Disconnect Switch exists for a reason. We hope you never have to use it, but
if something unexpected occurs, use the Power Disconnect Switch to immediately stop the
Lift from moving.
• Retrieve what you need from the Vehicle before lifting it. It is frustrating to raise a
Vehicle and then realize you left something inside. Never raise your Lift with people in the
Vehicle.
• Make sure the Vehicle is balanced. If there is extra weight on one end or the other, remove
it or balance it before raising the Vehicle.
• Center the Vehicle’s wheels on the Runway. Centered wheels keep the Vehicle balanced.
