Perform the Function Check as follows:
1. From the Ground Control Panel with no load in the plat-
form:
a. Ensure that the key selector switch and the platform lift
switch operates properly.
b. Ensure that all machine functions are disabled when
the Emergency Stop Button is depressed.
c. With platform raised a few feet (1m), ensure that the
manual descent control (located at the right rear of the
machine), lowers the platform properly.
2. From the Platform Control Console:
a. Ensure that the control console is firmly secured in the
proper location.
b. Ensure that all guards protecting switches are in place.
c. Operate all functions, drive/lift mode select switch, and
horn button.
d. Operate all platform joystick functions to ensure proper
operation of drive, lift, steer, and enable trigger switch
operation.
e. With the platform elevated on a smooth, firm, level sur-
face with no overhead obstructions, drive the machine
to check if the high drive cutout speed-limit is engaged
at the height indicated in Table 2-2. Ensure drive speed
is reduced from a top speed to a slower speed. Limit
switch locations shown in Figure 2-2. on page 3-9.

operation. The light/alarm should be activated, and lift
up disabled when tilted at or beyond the values in
Table 2-3.
NOTE: When the tilt indicator warning is activated the following func-
tions are affected; drive and lift up functions are disabled, plat-
form must be fully lowered (stowed) to drive out of tilt condition.
