plied to the emergency stop switch at the platform control
station. The Power Selector Switch should be in the off
position when recharging the batteries and/or parking the
machine overnight.
Emergency Stop Switch
This switch, when in the on (out) position, provides battery
power to the ground controls or platform controls, as
applicable. In addition, the switch can be used to turn off
power (push the switch in) to the function controls in the
event of an emergency. If the machine shuts down due to
a trouble fault, turning the Emergency Stop Switch off and
then on again will reset the JLG SMART™ system.
Motor Activation
With the power selector switch in the appropriate position
(platform or ground) and the applicable emergency stop
switch in the on position and a function switch or control-
ler is operated and held, the motor becomes activated
and operates the desired function. When operating the
platform controls, the applicable function switch must be
pressed before activating the controller to operate the
function.
IF A MOTOR MALFUNCTION NECESSITATES AN UNSCHEDULED
SHUTDOWN, DETERMINE AND CORRECT THE CAUSE BEFORE
RESUMING ANY OPERATION.
ALWAYS POSITION THE POWER SELECTOR AND EMERGENCY
STOP SWITCHES TO THE OFF POSITION WHEN THE MACHINE IS
NOT IN USE.
E3 SERIES SCISSOR LIFTS ARE EQUIPPED WITH A PQ CON-
TROLLER, WHICH FEATURES A TRIGGER SWITCH ON THE
FRONT OF THE JOYSTICK. THIS SWITCH MUST BE DEPRESSED
TO OPERATE THE JOYSTICK, SELECT DESIRED FUNCTION,
SQUEEZE THE TRIGGER, THEN POSITION THE JOYSTICK TO
FORWARD OR REVERSE, AS DESIRED.
4.4 RAISING AND LOWERING (LIFTING)
DO NOT RAISE THE PLATFORM EXCEPT ON A HARD, LEVEL
SURFACE FREE OF OBSTRUCTIONS AND HOLES.
Raising
1. If the machine is shut down, place the power selec-
tor switch to the desired position (platform or
ground).
2. Position the applicable emergency stop switch to
the on position.
3. If operating from the ground controls, position the lift
switch to up and hold until the desired elevation is
achieved. If operating from the platform controls,
press the lift switch and move the controller (joy-
stick) forward and hold until the desired elevation is
reached. The lift switch is part of the enable circuit,
which supplies power to the lift switch and the joy-
stick for 3 seconds after the lift switch is pressed. If
the joystick is not activated within 3 seconds after
the lift switch is pressed, power is removed from the
switch and the joystick and the switch must be
pressed again before activating the joystick. When
the joystick is returned to the center off position, the
operator has 3 seconds to re-activate the joystick or
select another function before power is removed by
the enable circuit. Do not try to operate the drive, lift,
and powered deck extension functions simulta-
neously. If the drive, lift, and powered deck exten-
sion functions are selected simultaneously, no
function will operate. If this occurs, pause, then
press only one of the function switches to activate
the function.
Lowering
ENSURE THE SCISSOR ARM AREA IS FREE OF PERSONNEL
PRIOR TO LOWERING THE PLATFORM.
If operating from the ground controls, position the lift
switch to down and hold until the desired elevation is
achieved or until the platform is fully lowered. If operating
from the platform controls, press the lift switch and move
the joystick backward and hold until the desired elevation
is reached or until the platform is fully lowered. The lift
switch is part of the enable circuit, which supplies power
to the lift switch and the joystick for 3 seconds after the lift
switch is pressed. If the joystick is not activated within 3
seconds after the lift switch is pressed, power is removed
from the switch and the joystick and the switch must be
pressed again before activating the joystick. When the joy-
stick is returned to the center off position, the operator has
3 seconds to re-activate the joystick or select another
function before power is removed by the enable circuit.
Do not try to operate the drive, lift, and powered deck
extension functions simultaneously. If the drive, lift, and
powered deck extension functions are selected simulta-
neously, no function will operate. If this occurs, pause,
then press only one of the function switches to activate
the function.
DO NOT LIFT DOWN WITHOUT COMPLETELY RETRACTING THE
PLATFORM EXTENSION.
