SECTION 3 - USER RESPONSIBILITIES AND MACHINE CONTROL
3-2 – JLG Sizzor – 3120761
Capacities
Raising platform above horizontal with or without any load
in platform, is based on the following criteria:
1. Machine is positioned on a smooth, firm and level
surface.
2. Load is within manufacturers rated capacity.
3. All machine systems are functioning properly.
Stability
This machine, as originally manufactured by JLG and
operated within its rated capacity on a smooth, firm and
level supporting surface, provides a stable aerial platform
for all platform positions.
3.4 CONTROLS AND INDICATORS
The machine is equipped with control panels that use
symbols instead of words to indicate control functions.
Refer to Symbols figure for these symbols and their corre-
sponding functions.
JLG SMART™ System
The machine is controlled by the JLG SMART™ System, a
24 volt, multiplex motor controller which works in conjunc-
tion with a joystick and several switches to operate all
machine functions.
Special operating characteristics of the JLG SMART™
System are noted where applicable. Special attention
should be paid to these operating characteristics, as they
may be somewhat different from those on previous JLG
machines.
IMPORTANT
IT 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. REC-
OMMENDS A MAXIMUM PRESSURE OF 750 PSI (52 BAR) AT A
MINIMUM DISTANCE OF 12 INCHES (30.5 CM) AWAY FROM THESE
COMPONENTS. IF ELECTRICAL/ELECTRONIC COMPONENTS
ARE SPRAYED, SPRAYING MUST NOT BE DIRECT AND BE FOR
BRIEF TIME PERIODS TO AVOID HEAVY SATURATION.
Battery Charger
The battery charger is located at the rear of the machine,
behind the ladder. The charger, which plugs into a stan-
dard 110 volt receptacle, is a 24 volt DC charger with an
output of 25 Amps. A built in automatic timer shuts down
charger operation when the batteries are fully charged. A
rocker switch circuit breaker is included to reset the
charger in the event of a loss of power. LEDs on the front
panel of the charger indicate the status of charger opera-
tion (Charge Complete, 80% Charge, Incomplete Charge,
Charger On, Abnormal Cycle).
Ground Control Station
DO NOT OPERATE FROM GROUND CONTROL STATION WITH
PERSONNEL IN THE PLATFORM EXCEPT IN AN EMERGENCY.
PERFORM AS MANY PRE-OPERATIONAL CHECKS AND INSPEC-
TIONS FROM THE GROUND CONTROL STATION AS POSSIBLE.
REFER TO SECTION 2 FOR PRE-OPERATIONAL CHECKS AND
INSPECTIONS.
1. Power Selector Switch - A three position, key-oper-
ated Power Selector Switch supplies operating
power to the platform or ground controls, as
selected. When positioned to platform, the switch
provides power to the emergency stop switch at the
platform controls. When positioned to ground, the
switch provides power to the emergency stop switch
at the ground controls. With the Power Selector
Switch in the center off position, power is shut off to
both platform and ground controls.
NOTE: With the Power Selector Switch in the off position,
the key can be removed in order to incapacitate the
machine on the jobsite to avoid unauthorized use of
the machine.
With the Power Selector Switch positioned to
ground, ground functions will operate at low speed at
all times.
Low speed is the default speed for all functions.
When the platform is elevated, all functions operate
in creep speed only.
2. Emergency Stop Switch - A two-position, red,
mushroom-shaped Emergency Stop Switch, when
positioned to on with the Power Selector Switch
positioned to Ground, furnishes operating power to
the ground control station. In addition, the switch
can be used to turn off power to the function con-
trols in the event of an emergency. Power is turned
on by pulling the switch out (ON), and is turned off
by pushing the switch in (off). Turning the Emer-
gency Stop Switch off and then on again will reset
the Smart System if a system fault has occurred and
the machine has shut down.
3. Lift Switch - A three-position, momentary-contact
Lift control toggle switch provides raising and lower-
ing of the platform when positioned to up or down.
4. Circuit Breaker - A push button reset 15 Amp circuit
breaker, located at the ground control panel, returns
interrupted power to the machine functions when
depressed.
5. Hourmeter (If Equipped) - The machine may be
equipped with an hourmeter to indicate the number
