Performing an Operational Test
We strongly recommend doing an Operational Test of your Lift with a typical Vehicle before starting
normal service.
Note: Residual air in the Hydraulic System can cause the Lift to shake, move erratically, or
squeak when you start using it; this is normal. If it does not go away after raising and
lowering the Lift two or three times, try bleeding air from the Hydraulic Cylinder. If it still
does not go away, refer to Troubleshooting for additional information.
To test your Lift:
1. Check the area around, above, and under the Lift for obstructions; move them if you find any.
2. Drive the Vehicle onto the Lift.
Put the Vehicle into park, put on the parking brake, put it in gear if it is a manual transmission, and
chock the rear Wheels.
3. Check all four Lifting Cables from the Top Cap down to the Slack Safety Sheave.
Verify that each Lifting Cable is straight between those two points. If any two are angled (not quite
straight), then the Top Caps may have been installed incorrectly.
4. Press and hold the Up button.
5. After the Runways pass one or two Safety Locks (you will hear them), release the Up button.
6. Pull down
and hold down
the Safety Lock Release Handle (next to the Crosstube), then press
and hold
the Lowering Handle (on the Power Unit).
7. When the Runways are fully lowered, release both handles.
8. Wait for one minute.
⚠ CAUTION Always take a break between cycles. The Power Unit’s motor is
not
constant duty.
If you run it continuously, you will damage it, which is
not
covered by the Warranty.
9. Repeat the process, this time raising the Runways higher.
10. 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 a one-minute break between cycles.
If you continue to have issues, refer to Troubleshooting for assistance.
