Adjust the Sequencing Cables
Maintaining proper adjustment of the sequencing
cables is essential for safe machine operation. An
unsafe working condition exists if the sequencing
cables are improperly adjusted. A frequent check
of the sequencing cables allows the inspector to
identify changes in the operating condition that
might indicate damage.
1 Fully lower the platform.
2 Check the tension on each sequencing cable by
grasping the cable halfway down the column
and pulling the cable from one side then to the
other. Measure the total distance between the
two points (this is the maximum deflection).

3.8 to 6.4 cm
3 Hold the end of the cable from turning and
adjust the tension nut to obtain correct tension
(deflection). Turn the adjustment nut clockwise
to increase the tension or counterclockwise to
decrease the tension.
Component damage hazard. Do
not exceed the recommended
tension.
4 Re-check the tension on each sequencing cable.
5 Repeat adjustment for each cable as required.
6 Raise and lower the platform through three
complete cycles and re-check the deflection.

Test the Power To Platform
Operation
AC power to the platform is intended to be an
extension cord to the platform for using hand tools.
1 Connect an appropriate extension cord to the
AC power supply cord at the base of the
machine.
2 In the platform, plug a power drill (or similar
tool) into the AC outlet.
Result: The tool should operate normally.
Note: GFCI outlet may require that the outlet be
reset with the reset button.
