Raising and Lowering Vehicles
This section includes instructions for raising and lowering a Vehicle.
To raise a Vehicle:
1. Make sure the Runways are on the ground. If they are not, move them down to the ground.
2. Drive a Vehicle onto the Runways.
Make sure all four wheels are
fully on the Runways, in the center of the Runways.
Put the Vehicle into park and put on the parking brake. Leave manual transmissions in gear.
3. Chock the Wheels.
4. Press and hold the Up Button on the Power Unit.
5. When the Runways get to the desired height, go up a little bit higher, then release the Up Button
and press and hold the Lowering Handle.
Do
not pull down and hold the Safety Lock Release Handle; this prevents the Lift from engaging
on its Safety Locks.
How do you know if one of the four Safety Locks has, for some reason, not engaged? If this
happens, the non-engaged corner of the Lift will continue to go down, while the others stay where
they are.
⚠ WARNING Only leave your Lift either engaged on Safety Locks or fully lowered.
6. With the Runways engaged on the Safety Locks, check around the Vehicle to make sure
everything looks good.
Do not go under the Lift until you are sure it is engaged on all four Safety Locks.
To lower a Vehicle:
1. Make sure there are no obstructions under the Runways you are about to lower.
If there are, move them out of the way
before lowering the Runways.
2. Press and hold the Up Button for two or three seconds.
Moving the Lift
up gets it off the Safety Locks, which is required for lowering the Lift.
3. Pull down and hold the Safety Lock Release Handle, then press and hold the Lowering Handle.
4. When the Runways are fully lowered, release both handles.
5. Remove the wheel chocks.
6. Drive the Vehicle off the Lift.
