Lift - After selecting the lift function, engage the trigger
switch lever, moving the control handle backward will raise
the platform and moving the control handle forward will lower
the platform. The speed on all selected functions is propor-
tionally controlled by the distance of travel of the hand con-
troller.
Steer - The thumb-operated steer switch on top of the hand
controller activates the steer wheels in the direction activated
(right or left).
3. Emergency Stop Switch - A two-position, red, mushroom-
shaped emergency stop switch functions to provide power

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 pushing the switch in (off).
4. Trigger Switch - This switch is located on the front of the
controller. The trigger switch acts as an enable and must be
depressed before operating the drive, steer and lift functions.
