4.6 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: On CE market machines, the Platform Leveling Override function
will only operate when no other functions are being activated.
To Level Up or Down - Position the Platform/Level
control switch Up or Down and hold until the plat-
form is level.
Platform Rotation
To rotate the platform to the left or right, use the
Platform Rotate control switch to select the direc-
tion and hold until desired position is reached.
4.7 BOOM
A RED TILT WARNING LIGHT IS LOCATED ON THE CONTROL CONSOLE
WHICH LIGHTS WHEN THE CHASSIS IS ON AN EXCESSIVE SLOPE. DO
NOT SWING OR RAISE BOOM ABOVE HORIZONTAL WHEN LIGHT IS
LIT.
DO NOT DEPEND ON TILT ALARM AS A LEVEL INDICATOR FOR THE CHASSIS. TILT
ALARM INDICATES CHASSIS IS ON AN EXCESSIVE SLOPE (4 DEGREE OR GREATER ON CE
& AUSTRALIA SPEC MACHINES, 5 DEGREE OR GREATER ON ANSI, CSA, & JAPAN SPEC
MACHINES). CHASSIS MUST BE LEVEL BEFORE SWINGING, OR RAISING BOOM ABOVE
HORIZONTAL OR DRIVING WITH THE BOOM ELEVATED.
TO AVOID TIP OVER IF RED TILT WARNING LIGHT LIGHTS WHEN BOOM IS RAISED
ABOVE HORIZONTAL, LOWER PLATFORM TO GROUND LEVEL. THEN REPOSITION
MACHINE SO THAT CHASSIS IS LEVEL BEFORE RAISING BOOM.
TRAVELING WITH BOOM BELOW HORIZONTAL IS PERMITTED ON GRADES AND SIDE
SLOPES SPECIFIED IN THE OPERATING SPECIFICATIONS SECTION OF THIS MANUAL.
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINERY IF ANY CONTROL LEVER OR
TOGGLE SWITCH CONTROLLING PLATFORM MOVEMENT DOES NOT RETURN TO THE
‘OFF’ OR NEUTRAL POSITION WHEN RELEASED.
