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 EMER-
GENCY 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 EXIT-
ING THE PLATFORM TO PREVENT IT BEING DAMAGED WHEN OPER-
ATING 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 MOVE-
MENT 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 dur-
ing 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 control.

(Item 13, Figure 4-3.)
NOTE: During normal operation of the machine, the platform
will automatically maintain its position.
• To manually Level Up, turn the select switch clockwise
and hold until desired position is reached.
