THE PLATFORM. INCORRECT USE COULD CAUSE THE LOAD/OCCUPANTS TO SHIFT OR
FALL. FAILURE TO DO SO COULD RESULT IN DEATH OR SERIOUS INJURY.
NOTE: When the Boom Control Select Switch is in the Manual mode,
Platform leveling only functions during Main Lift operation.
When the Boom Control Select Switch is in the Automatic mode,
Platform Leveling is active during all functions except during
