Capacities
Raising platform 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 manufacturer’s 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 FOR NON
PROPORTIONAL CONTROL
The machine is equipped with control panels that use
symbols instead of words to indicate control functions.
Battery Charger
NOTE: If batteries are run down to under 6 volts, the sup-
plied battery charger will not pick up the charge.
The battery charger is located in the right side battery
door. The charger is a 20 Amp, SCR-style charger
equipped with a manual switch that allows the operator to
select 110-125 Volt input or 220-250 Volt input. A rocker
switch circuit breaker is included to reset the charger in
the event of a loss of power. LED’s on the front panel of
the charger indicate the status of charger operation
(Charge Complete, 80% Charge, Incomplete Charge,
Charger On, Abnormal Cycle).
Under normal operation the battery charger should work
as follows:
NOTE: Make sure the DC is connected and then plug the
charger into the AC outlet.
1. All 5 lights will flash 3 times.
2. Each light will flash once from top to bottom.
3. All 5 lights will flash 3 more times.
4. The charger 25% light will come on (Solid if in wet
mode, and flashing if in sealed mode).
5. 5 seconds later the charger on light will come on the
the charger will start recharging the battery.
a. If the battery is depleted, the 25% light will stay
on until the batteries reach their 80% level,
where the 80% light come on and the 25% light
will go out.
b. The following will occur if the batteries being
charged are full:
The charger will read 80% and remain there for
approximately 70 minutes during the DV/Dt sec-
tion of the charge, after which the charger will go
to 100% and shut off as described below.
6. If there is a problem wit the battery or if the charge
cycle is interrupted the charger could shut down
and the abnormal light will come on.
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-operated 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 emer-
gency 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 con-
trols.
NOTE: With the power selector switch in the off position, the
key can be removed in order to avoid unauthorized
use of the machine.
Low speed is the default speed for all functions when
the platform is fully lowered. 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 (pulled out) with
the power selector switch positioned to ground, fur-
nishes operating power to the ground control sta-
tion. In addition, the switch can be used to turn off
power to the function controls 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).
