Final Leveling
The following procedure describes how to fine tune how level your Lift is.
To do final leveling on the Lift:
1. Raise your Lift to the first Safety Lock position.
2. Use a transit level or other leveling mechanism to evaluate how level the Posts and Runways are.
3. If you need to adjust a Runway, use the Top Nut and Stop Nut on the Top Cap of each Post to
make adjustments to the Ladder in that Post (which impacts the levelness of the Runway and
when the Safety Locks engage).
4. Raise the Lift to full height, listening as the Safety Locks engage.
If the Safety Locks are engaging at the same time, no further adjustments are necessary.
If the Safety Locks are not engaging at the same time, check the leveling, make necessary
adjustments, and then raise the Lift again and listen as the Safety Locks engage.
5. When you are satisfied the Lift is level, firmly secure the Nuts at the top of each Post.
Installing Accessories
The accessories available for your Lift include:
Tire Chocks
Tire Chocks go behind the back Tires of a Vehicle to make sure it stays where you put it.
To use your Tire Chocks: wedge them in behind the rear Tires of a Vehicle when it is in the desired
location on the Lift, then remove them when you want to take the Vehicle off the Lift.
JP45 Bottle-Jack Tray
Holds one or two Bottle Jacks (not included), which let you get a Vehicle’s wheels up off the Runways.
Refer to the JP45 Quick Start Guide installation and usage instructions.
Rolling Jack
A Rolling Jack lets you raise the Wheels of the Vehicle on the Lift off the Runway. It takes a pair of
Rolling Jacks to get all four Wheels off the Runway.
Rolling Jacks are a separate purchase.
Brake jobs and suspension work, for example, are much easier to do to the Vehicle on the Lift if the
wheels are off the Runways.
The Rolling Jack comes with its own manual; refer to that manual for instructions.
