⚫Stay away from the machine if it contacts a
live electric wire. Do not touch or operate the
machine from the ground or the platform
before cutting off the power supply.
⚫Do not operate the machine in inclement
weather.
⚫Do not use the machine as a ground for
welding. This could damage electrical
components on the machine.
⚫Do not touch the battery charger when
charging the batteries.
△
!Tip Over Hazard
The personnel, equipment, and material
on the platform shall not exceed the
maximum bearing capacity of the
platform and the extending platform.
Refer to Chapter 10 –Specifications for
model capacities.
1) The platform can only be elevated on flat,
solid ground.
2) The maximum elevated drive speed for
models AS1932E/AS2646E/AS3246E is
0.5mph (0.8 kph).
The maximum elevated drive speed for
model SS1230E is 0.31mph (0.50 kph).
3) Do not use the tilt alarm as a level indicator.
The tilt alarm only sounds when the machine
is severely tilted.
4) If the tilt alarm sounds: lower the platform and
move the platform to flat, solid ground. If the
tilt alarm sounds when elevating the platform,
lower the platform immediately.
5) If the machine is used outdoors, do not
elevate the platform when wind speed is
above 28mph (12.5 m/s). If wind speed
exceeds the limit after elevating the platform,
immediately lower the platform and stop all
machine operation.
6) The ambient temperature range for use of
this machine is -4℉to104℉(-20℃to 40℃)
7) The relative humidity for use of this machine
shall be no greater than 90% (at 68℉
[20℃]).
8) The allowable voltage fluctuation of the
machine is ±10%.
9) Do not increase the surface area of platform
or load. Increasing the exposure area in wind
will reduce the stability of machine.

LGMG North America Inc. Operation and Safety Manual
4
10) When the platform is caught, stuck or blocked
by a nearby item and is unable to normally
move, do not try to release the platform using
the platform controller. All personnel must be
removed from the platform before releasing
the platform using the ground controller.
11) Be cautious and lower drive speed when the
machine is fully lowered and driving on an
uneven road, a gravel road, an unstable or
smooth surface, near a hole, or on a slope.
12) Do not drive the machine on any uneven or
unstable roads or in any other dangerous
conditions, when the platform is elevated.
13) Do not use the platform to push any item or
object.
14) Do not use the machine as a crane.
15) Do not place, anchor, or suspend any load
from any part of the machine.
16) Do not push the machine or other items using
the platform.
17) Do not operate the machine when the
chassis tray is pulled out.
18) Do not lean the platform against any nearby
structure or wall.
20) Do not modify or limit the use of the limit
switch.
21) Do not bind or tie the platform to a nearby
structure or wall.
22) Do not place the load outside the platform
guard rail.
23) Do not modify or change the aerial work
platform without the written consent of the
manufacturer. Installing an additional device used
for carrying tools or other materials on the
platform, pedal, or guard rail will increase
platform weight, platform surface area, and load.
24) Do not modify or damage any safety or
stability related parts of the machine.
25) Do not replace any key stability-related parts
with those with different weights or specifications.
26) It is forbidden to use a battery weighing less
than the original battery. The battery installed on
the chassis is used and counterweight and is vital
for the stability of machine. Every battery has a
different weight (as detailed in the following
table).

27) Do not place the steps, ladders, or
scaffolding in the platform or lean them against
any part of the machine.
28) Tools and materials, evenly distributed and
able to be safely moved by the operator in the
platform, can be carried in the platform only.
29) Do not use the machine on a movable
surface or vehicle.
30) Keep all tires in good condition and
appropriately tighten the lug nuts.
△
!Crushing Hazards
⚫Do not place arms, hands, or fingers
in any position where there is a
hazard of potential crushing by the
machine’s scissors.
⚫When the machine is being driven
from the ground using the controller,
use good judgment and carefully
plan the travel path. Keep a safe
distance between the operator,
machine and any fixed objects, walls,
or buildings.
△
!Hazards When Operating on a
Slope
⚫Do not drive the machine on a slope
that exceeds the slope and side
slope rating of the machine. The
rated value of slope is applicable to
a stowed machine. Refer to Chapter
10 –Specifications.
△
!Falling Hazards
⚫All workers in the platform must use
approved safety harnesses and
attach the lanyard to the provided
anchor points in the platform. Each
anchor point is limited to one
lanyard.
⚫Do not climb on or sit on the guard
rail of the platform. Firmly stand on
the platform floor at all times.
⚫Do not climb down the platform
scissors when the machine is
elevated.
⚫Keep the platform floor free from
debris.

LGMG North America Inc. Operation and Safety Manual

obstacles within the machine’s sight
line and in any blind spots when
starting or running the machine.
⚫Pay attention to the position of the
extending platform when moving the
machine.
⚫Check the workstation to avoid any
overhead barriers or other possible
hazards in the work site.
⚫Pay attention to any crushing
hazards when holding the guard rail
of the platform.
⚫The operator must follow the
manufacturer’s service rules for
personal protection equipment, the
service rules for the workstation,
and the laws and regulations made
by the local government.
⚫Observe and follow the traveling
arrow and the turning direction
arrows on the platform controller
and the platform’s label and
nameplate.
⚫Do not operate the machine on the
line of any crane or movable
overhead machine, unless the crane
controller is locked and/or the
potential bump prevention measure
is taken.
⚫Dangerous driving or careless
operation when running the machine
are strictly prohibited.
⚫The platform can be lowered only
when there are no personnel or
barriers below the platform.
⚫Limit travel speed according to
ground conditions, traffic, road
grade, personnel position, or any
other possible bump factors.
