Performing an Operational Test
BendPak strongly recommends doing an Operational Test of your Lift with a typical Vehicle before
starting normal service (a typical Vehicle is not required, but is recommended).
⚠
DANGER
When you even hear the words “automotive lift,” your brain should automatically
remember that lifting a Vehicle is a serious endeavor with life-threatening risks.
Focus on what you are doing. Automotive Lifts are dangerous tools when used by
inexperienced or impaired operators.
Do not assume you are going to be
safe this time because nothing happened last time
.
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
information.
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 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.
Check the area around, above, and under the Lift for obstructions; move them if you find any.
2.
Drive the Vehicle onto the Lift. 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.
Both Runways start rising.
4.
After the Runways pass one or two Safety Locks (you will hear them as they pass), release the Up
button.
The Runways stop rising.
5.
Press
and hold
the Pushbutton on the Pushbutton Air Valve, then press
and hold
the Lowering
Handle.
The Runways start lowering.
6.
When the Runways get to the ground, release the Pushbutton and the Lowering Handle.
7.
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.
8.
Repeat the process, this time raising the Runways to a higher Safety Lock.
9.
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
