PLATFORM

Platform Level Adjustment

ONLY USE THE PLATFORM LEVELING OVERRIDE FUNCTION FOR SLIGHT LEVELING OF
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
telescope operation. Also, when in the Manual mode, the Con-
trolled Arc and Controlled Angle systems are not active.
During normal operation of the machine, the plat-
form will automatically maintain it's position. To
manually Level Up or Down - Position the Platform/
Level control switch Up or Down and hold until the
desired platform position is obtained.
