CHECK THE BUBBLE LEVEL TO CONFIRM UNIT IS LEVEL (BUBBLE
IS IN THE 1° GREEN (CENTER) AREA) AND THAT THE TRACKS ARE
OFF THE GROUND BEFORE OPERATING THE BOOM FUNCTIONS. IF
THE BUBBLE IN THE LEVEL IS NOT IN THE GREEN AREA, AFTER
USING THE AUTO-LEVEL FUNCTION, SHUT DOWN THE MACHINE
AND HAVE THE MACHINE REPAIRED BY A QUALIFIED SERVICE
TECHNICIAN.
Each outrigger has an orange light installed. All lights will be
on steady if the outriggers are positioned properly. No lights
will be on if the outriggers are not set properly.
IF ONE OF THE ORANGE LIGHTS LOCATED ON EACH OUTRIGGER
SHOULD REMAIN ON WHEN THAT OUTRIGGER IS LIFTED FROM
THE GROUND, STOP THE MACHINE IMMEDIATELY AND CALL A
QUALIFIED JLG SERVICE TECHNICIAN AS THIS INDICATES A PROB-
LEM WITH THE CORRESPONDING OUTRIGGER MICRO SWITCH.
IF THE SLOPE EXCEEDS 10°, THE MACHINE IS NOT CAPABLE OF
PROPERLY SETTING THE OUTRIGGERS AND LEVELING ITSELF.
OPERATION OF THE BOOM AND PLATFORM FUNCTIONS WILL NOT
BE ALLOWED IN THIS CONDITION. THE MACHINE IS CONSIDERED
STABILIZED WHEN LEVELED TO LESS THAN 1° AND THE TRACKS
ARE LIFTED AT LEAST 2 IN. (5 CM) FROM THE GROUND.
STABILIZING THE MACHINE WITH AN INCLINATION DEGREE
HIGHER THAN THE ONE ALLOWED COULD CAUSE INSTABILITY OF
THE MACHINE
If the platform ladder is higher than 16 in. (40 cm) off the
ground when the ladder is lowered, when setting the machine
on outriggers from the ground position, lower the outriggers
until the ladder is less than 16 in. (40 cm) off the ground. Then
enter the platform to properly set the machine up on outrig-
gers.
