4.7 BOOM/PLATFORM OPERATION
THE BOOM WILL NOT OPERATE UNTIL THE OUTRIGGERS ARE PROPERLY
SET AND MACHINE IS LEVELED.
AT PLATFORM/REMOTE CONTROL STATION, TWIST THE EMERGENC Y
STOP BUTTON CLOCKWISE TO BE IN THE OUT POSITION, START ENGINE
AND ACTIVATE FOOTSWITCH FOR ALL PLATFORM/ REMOTE CONTROL
FUNCTIONS.
ALWAYS STOW (RAISE) THE LADDER AFTER ENTERING OR EXITING THE
PLATFORM TO PREVENT IT BEING DAMAGED WHEN OPERATING THE
MACHINE.
If the operator attempts to raise the JIB with more than the
allowed capacity in the platform a maximum weight
reminder icon appears in the middle of the platform/remote
LCD display and the function stops.
NOTE: At low temperatures start the motor and let it run for a
few minutes, so that the hydraulic oil circulates and
reaches at least 50°F (10°C) before operating the plat-
form.
Overload Alarm
If the platform is overloaded all the boom functions are
stopped, "Overload in Platform" error message appears on
the platform/remote display and the alarm sounds. To
restore the boom functions it is necessary to remove the
extra load.
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF ANY CONTROL
LEVER OR 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 YOUR FOOT FROM THE FOOT SWITCH AND/OR USE
EMERGENCY STOP SWITCH TO STOP THE MACHINE.
If the platform is lifted from the proper mounting position
during the use of the machine, an alarm will sound and all
the movements of the machine will stop. An error message
will appear on the LCD display of the platform/remote con-
trol.

form will automatically maintain its position.
