1. Trigger Switch - This switch is located on the front of
the joystick controller. The trigger switch acts as an
enable and must be depressed before operating the
drive, steer and lift functions. When released, the func-
tion being operated will stop.
2. Joystick Controller - The control handle controls
three functions: drive, lift, and steer.
Drive - The drive function must be selected using the
drive/lift selector switch (items 5 and 6 on the Platform
Control/Indicator panel - Figure 3-8.), prior to moving
the control handle. After selecting the drive function,
engage the trigger switch lever, then move the control
handle forward to drive the machine forward or move
the control handle backwards to drive the machine
backward.
Lift - After selecting the lift function using the drive/
lift selector switch (item 4 and 5 on the Platform Con-
trol/Indicator panel - Figure 3-8.), engage the trigger
switch lever, moving the control handle backward to
raise the platform and moving the control handle for-
ward will lower the platform.
The speed on all selected functions is proportionally
controlled by the distance of travel of the hand con-
troller from the center position.
Steer - The thumb-operated steer switch on top of the
control handle activates the steer wheels in the direc-
tion activated (right or left).
3. Steer Switch - The steer switch is a thumb operated
switch located at the top of the control handle.
Depressing the switch to the right will steer the
wheels to the right. Depressing the switch to the left
will steer the wheels to the left.
4. Emergency Stop Switch - A two-position, red, mush-
room-shaped emergency stop switch functions to
provide power to the platform control station and also
to turn off power to the platform function controls in
the event of an emergency. With the Power selector
switch positioned to platform, power is turned on by
pulling the switch out (on), and is turned off by push-
ing the switch in (off ).
