4.2 GENERAL
This section provides the necessary information needed
to operate the machine. Included in this section are the
procedures for starting, stopping, traveling, steering, park-
ing, platform loading and transporting the machine. It is
important that the user read and understand the proper
procedures before operating the machine.
4.3 MOTOR OPERATION
Power Selector Switch
The power selector switch functions to direct battery
power to the desired control station. With the switch in the
ground position, battery power is supplied to the emer-
gency stop switch at the ground control station. When the
switch is in the platform position, battery power is sup-
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.
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 from
the ground controls, the power selector switch must be
held in the ground position while the function is being
operated. When operating the platform controls, the lift
switch must be used in conjunction with the enable
switch, to drive the lever must be depressed in conjunc-
tion with the joystick travel.
IF A MOTOR MALFUNCTION NECESSITATES UNSCHEDULED
SHUTDOWN, DETERMINE AND CORRECT CAUSE BEFORE
RESUMING ANY OPERATION.
ALWAYS POSITION POWER SELECTOR AND EMERGENCY STOP
SWITCHES TO THE ‘OFF’ POSITION WHEN MACHINE IS NOT IN
USE.
4.4 RAISING AND LOWERING (LIFTING)
DO NOT RAISE PLATFORM EXCEPT ON A HARD, LEVEL SUR-
FACE FREE OF OBSTRUCTIONS AND HOLES.
NOTE: The lift switch will not operate if the red trigger switch
on the joystick is depressed.
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 desired elevation is
achieved. If operating from the platform controls,
press and hold the enable switch, move the lift
switch forward (up) and hold until desired elevation
is reached. The lift switch works in conjunction with
the enable switch.
Lowering
ENSURE SCISSOR ARM AREA IS FREE OF PERSONNEL PRIOR
TO LOWERING PLATFORM.
If operating from the ground controls, position the lift
switch to down and hold until desired elevation is
achieved or until platform is fully lowered. If operating
from the platform controls, press the enable switch and
push the lift switch backward (down) and hold until
desired elevation is reached or until platform is fully low-
ered. The lift switch works in conjunction with the enable
switch.
DO NOT ‘LIFT DOWN’ WITHOUT COMPLETELY RETRACTING THE
PLATFORM EXTENSION.
