4.8 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 Angle system is not active.
During normal operation of the machine, the platform will auto-
matically 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.
Platform Rotation
To rotate the platform to the left or right, use the Platform Rotate
control switch to select the direction and hold until desired posi-
tion is reached.
4.9 BOOM
DO NOT SWING OR RAISE BOOM ABOVE HORIZONTAL WHEN MACHINE IS OUT OF
LEVEL.
DO NOT DEPEND ON TILT ALARM AS A LEVEL INDICATOR FOR THE CHASSIS.
TO AVOID TIP OVER, LOWER PLATFORM TO GROUND LEVEL. THEN DRIVE MACHINE TO
A LEVEL SURFACE BEFORE RAISING BOOM.
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF ANY CONTROL LEVER OR
TOGGLE SWITCH CONTROLLING PLATFORM MOVEMENT DOES NOT RETURN TO THE
‘OFF’ OR NEUTRAL POSITION WHEN RELEASED.
IF THE PLATFORM DOES NOT STOP WHEN A CONTROL SWITCH OR LEVER IS RELEASED,
REMOVE FOOT FROM FOOTSWITCH OR USE EMERGENCY STOP SWITCH TO STOP THE
MACHINE.
