Loaded Platform Sequence
Park the machine on flat level surface. Machine power must be on. Ensure that the platform is
completely empty and there are no ‘extra’ items attached to the platform or guard rails that may
add weight to the platform beyond that of an empty platform.
Place weight in the center of the platform equal to rated platform capacity (500 LBS).
Turn the key switch to the Platform position. This will prevent the platform from lifting during the
next step.
Using the lower Lift Switch (located on the lower control panel) perform the following sequence
of up and down movement of the toggle switch. Do not operate the switch so slowly as to hold
the switch more than 2.5 seconds or the sequence will be terminated.
