Note
The lower controls override the upper controls. If the up-
per control emergency stop button is engaged the lower
controls can still be used to operate the aerial platform.
Push the emergency stop button inward when the
upper controls are not in use to protect against unin-
tentional operation.
Drive Joystick
The drive joystick (refer to Figure 6.4) is used to control
forward and reverse motion of the aerial platform. It is
also used to steer the machine. The steering and drive
functions may be operated simultaneously.
Note
The distance the joystick is moved is proportional to the
speed of the function.
To move the aerial platform forward, hold the joystick
forward as indicated by the directional arrows on the
chassis.
To move the aerial platform backward, hold the joystick
backward as indicated by the directional arrows on
the chassis.
To steer to the right, hold the joystick to the right as
indicated by the directional arrows on the chassis.
To steer to the left, hold the joystick to the left as indi-
cated by the directional arrows on the chassis.
