GrandPrix Two-Post Lifts 54 P/N 5900209 — Rev. D3 — Feb. 2020
Perform an Operational Test
Before putting your Lift into normal operation, we recommend raising and lowering it several times with
a typical Vehicle on the Lift. This will help you get a feel for how to operate the controls and help get
any residual air out of the Hydraulic System (sometimes called “bleeding” the system).
⚠ DANGER Automotive Lifts are dangerous tools when used by inexperienced, impaired, or
distracted technicians. When you even hear the words “automotive lift,” your brain
should automatically register the fact that lifting a vehicle is a serious endeavor with
life-threatening risks if mandatory lifting precautions are ignored.
During the Operational Test, check for proper installation and operation. Do not raise any additional
Vehicles until a thorough Operational Test has been done with a typical Vehicle.
⚠ WARNING Never raise a Vehicle whose weight exceeds the rated capacity of the Lift. Do not
leave the controls until the Lift is engaged on its Safety Locks. Only trained
personnel should raise or lower the Lift.
To perform an Operational Test:
1. Follow the instructions in Raising the Lift and Lowering the Lift to safely raise and lower a
Vehicle on the Lift.
⚠ WARNING Be sure to follow the instructions carefully when it comes to contacting the
manufacturer’s recommended Lifting Points on the underside of the Vehicle. If you
do not, the Vehicle could become unstable and fall, which could damage the
Vehicle, damage the Lift, and injure or even kill anyone under the Vehicle.
2. Adjust the Lift Arms under the Vehicle so the Adapters are
directly under the Lifting Points for
the Vehicle you are raising.
If necessary, use the included Lift Pad extensions for extra height.
3. Raise the Lift until
just before the Lift Pads make contact with the Lifting Points.
If this is the very first use of the Lift, it will take a few seconds to start rising. The Hydraulic Fluid has
to fill the Hydraulic Lines before the Lift starts to rise.
4. Check the Arm Restraint Gears on all four Lift Arms to make sure they are engaged.
If they are not engaged, move the Lift Arms back and forth until they engage.
5. Raise the Lift until the tires of the Vehicle are a few inches off the ground.
6. Check to make sure all four Lift Pads are making solid contact with the Lifting Points.
If any of the Lift Pads are
not making solid contact with the Lifting Points, carefully lower the Lift
and start over again; the Lift Pads
must make solid contact with the Lifting Points.
7. Raise the Vehicle approximately three feet (one meter) off the ground, then lower it back down.
Watch and listen as the Lift raises and then lowers. The Lift may move erratically or make some
odd noises the first couple of times you use it; this is normal.
Tip Residual air in the Hydraulic System can cause the Lift to shake, move erratically, or
squeak; this is normal when you first start using the Lift. It will soon stop doing this,
as the Hydraulic System is self-bleeding.
