6.7 MACHINE SETUP
When a machine digit item is selected, press the UP or
DOWN arrow keys to adjust its value, for example:
GROUND ALARM:
2 = LIFT DOWN
The effect of the machine digit value is displayed along
with its value. The above display would be selected if the
machine was equipped with a ground alarm and you
wanted it to sound when lifting down. There are certain
settings allowed to install optional features or select the
machine model.
When selection the machine model to match the size of
the machine, the personality settings will all default to the
factory recommended setting.
NOTE: Refer to Table 6-6, Personality Ranges/Defaults, and
in this Service Manual for the recommended factory
settings.
NOTE: Password 33271 will give you access to level 1,
which will permit you to change all machine person-
ality settings.
There is a setting that JLG strongly recommends that you
do not change. This setting is so noted below:
ELEVATION CUTBACK
CHANGING THIS SETTING MAY ADVERSELY AFFECT THE PER-
FORMANCE OF YOUR MACHINE.
ITS IS A GOOD PRACTICE TO AVOID PRESSURE-WASHING ELEC-
TRICAL/ELECTRONIC COMPONENTS. SHOULD PRESSURE-
WASHING BE UTILIZED TO WASH AREAS CONTAINING ELECTRI-
CAL/ELECTRONIC COMPONENTS, JLG INDUSTRIES INC. RECOM-
MENDS A MAXIMUM PRESSURE OF 750 PSI (52 BAR) AT A
MINIMUM DISTANCE OF 12 INCHES (30.5CM) AWAY FROM
THESE COMPONENTS. IF ELECTRICAL/ELECTRONIC COMPO-
NENTS ARE SPRAYED, SPRAYING MUST NOT BE DIRECT AND BE
FOR BRIEF TIME PERIODS TO AVOID HEAVY SATURATION.
