⚫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 AS1930/AS1930EAS1932E/
AS2632E/AS2646E/ AS3246E/AS4046E/
AS4650E/AS1932/AS2632/ AS2646/
AS3246/AS4046/AS4650 is 0.5mph (0.8
kph). The maximum elevated drive speed
for models SS1230E/SS1432E/SS1932E is
0.31 mph (0.5 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) If the machine is used indoors, do not
elevate the platform when wind speed is
above 0mph (0m/s).
7) The ambient temperature range for use of
this machine is -4℉to104℉(-20℃to 40℃)
8) The relative humidity for use of this machine
shall be no greater than 90% (at 68℉
[20℃]).
9) The allowable voltage fluctuation of the
machine is ±10%.
10) Do not increase the surface area of platform
or load. Increasing the exposure area in wind

LGMG North America Inc. Operation and Safety Manual
5
will reduce the stability of machine.
11) 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.
12) 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.
13) Do not drive the machine on any uneven or
unstable roads or in any other dangerous
conditions, when the platform is elevated.
14) Do not use the platform to push any item or
object.
15) Do not use the machine as a crane.
16) Do not place, anchor, or suspend any load
from any part of the machine.
17) Do not push the machine or other items using
the platform.
18) Do not operate the machine when the chassis
tray is pulled out.
19) 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).
