Use and Care Manual

HD-9 Series Four-Post Lifts 66 P/N 5900123 — Rev. M1 — March 2020
Test the Lift
BendPak strongly recommends doing an Operational Test of your Lift with a standard Vehicle on the
Runways before starting normal service (a typical Vehicle is not required, but is recommended).
During the Operational Test, watch the Lift and its components and check for proper installation and
operation. If you run into an issue that does not go away, refer to Troubleshooting.
Note: Residual air in the Hydraulic Systems can cause the Lift to shake, move erratically, or squeak
when you start using it; this is normal. If it happens, do not worry; it will go away as the
Hydraulic System is self-bleeding. If it does not go away soon, try bleeding the Cylinder of air.
If it still does not go away, refer to Troubleshooting for additional information.
To test your Lift:
1. Before you start using your Lift, make sure to check for people, pets, or objects that might be in
the path of the Lift as you raise and lower it.
2. Drive the Vehicle onto the Runways; try to center the Vehicle’s Tires in the middle of each Runway.
Put the Vehicle into park, put on the parking brake, put it in gear if it is a manual transmission, and
chock the wheels.
3. Press and hold the Up button.
4. After the Runways pass three or four Safety Locks (you will hear them), release the Up button.
5. Press and hold the pushbutton on the Pushbutton Air Valve, then press and hold the Lowering
Handle.
The Runways back down onto the Safety Locks they just passed.
⚠ CAUTION Never leave the Lift without making sure that all four Safety Locks
have engaged on locking positions at the same height
. If one of the four
Safety Locks do not fully engage, the Runways will not be level and you could risk
damaging any Vehicles sitting on or underneath the Runways.
6. Press the Up button for a few seconds to disengage the Runways from the Safety Locks, then
release the Up button.
7. Press and hold the pushbutton on the Pushbutton Air Valve, then press and hold the Lowering
Handle.
8. When the Runways reach the ground, release the Lowering Handle.
9. Wait for one minute.
⚠ CAUTION Always take a break between cycles. The Power Unit’s motor is not constant duty;
it cannot be run continuously.
10. Repeat the process, this time raising the Runways to a higher Safety Lock.
11. If the Lift is working without shaking, moving erratically, or squeaking, there is no need to repeat
the procedure.
If the Lift is shaking, moving erratically, or squeaking (which is normal during the start-up period),
repeat the procedure a couple more times, with at least a one-minute break between cycles.
If you continue to have issues, refer to Troubleshooting for assistance.
