1.7 Danger of Tip-over
1) The total weight of the personnel,
equipment and materials on the platform
shall not exceed the maximum bearing
capacity of the platform.

Platform
2) Only when the machine is on solid, flat
ground can the boom be raised and
extended.
3) If the platform is overloaded, the buzzer will
alarm. Please reduce the platform load first.
4) When the platform is raised, the speed of
the machine shall not exceed 0.8km/h
(0.5mph).
5) The tilt sensor cannot be considered as a
level indicator. The buzzer on the rotary

LGMG North America Inc. Operation and safety Manual
5
table will only sound when the machine is
heavily tilted.
6) If the buzzer sounds when the platform is
lifted, be very careful, as the Machine not
level indicator lamp will come on and the
drive function will not be available in both
directions. First determine the state of the
boom on the slope, as shown below. Then
lower the boom as follows before moving
the machine to a solid, level ground. Do not
rotate the boom when lowering.
If the buzzer sounds when the platform goes
uphill
①Lower the boom
②Retract the boom
If the buzzer sounds when the platform goes
downhill
①Retract the boom
②Lower the boom
7) Do not raise the boom when the wind
speed may exceed 12.5m/s(28mph). If the
wind speed exceeds 12.5m/s(28mph) after
the boom is raised, lower the boom and do
not continue to operate the machine.
8) Do not operate the machine in strong wind
or gust. Do not increase the surface area of
the platform or load. Increasing the area
exposed to the wind will reduce the stability
of the machine.
9) When the platform is tripped, stuck, or other
nearby objects hinder its normal movement,
do not use the PCU to operate the machine.
If you intend to operate the machine by
using the GCU, you must operate it after all
personnel have left the platform.
10) Be very careful and reduce the speed when
the machine is driven on a surface with
crushed stone, unstable or slippery or near
a hole or on a steep slope in the stowed
state.
11) When the boom is raised, the machine
cannot be driven on uneven terrain,
unstable surfaces or other dangerous
conditions, or near these areas.
12) Do not push or pull any object outside the
platform. The maximum allowable manual
force of the machine is 400N.
13) The machine cannot be used as a crane.
14) Do not place, tie down or hang loads on
any part of the machine.
15) Do not push machine or other objects with
boom.
16) When the vehicle goes downhill, please
operate in the low speed range, and it is
forbidden to go downhill at high speed.
17) When the vehicle is driving on a slope, it is
forbidden to use the emergency stop

LGMG North America Inc. Operation and safety Manual
6
switch.
1.8 General Safety
1) The machine cannot be operated with the
hood open.
2) Do not allow boom to approach or touch
any objects.
3) All sensors such as those for long angle,
inclination, weighing, rope breaking
detection shall not be changed or disabled.
4) Boom or platforms must not be bound to
adjacent objects.
5) Do not modify this machine without the
prior written permission of the manufacturer.
Installing additional devices for placing
tools or materials on platform, pedals or
guardrails will increase the weight and
surface area of the platform.
6) Ladders or scaffolding shall not be placed
in the platform or against any part of the
machine.
7) Only tools and materials that are evenly
distributed and can be safely moved by
people on the platform can be transported.
8) Do not use machines on moving or shaky
surfaces or on vehicles.
9) Do not place hands and arms close to
areas with danger of cutting or smashing.
10) Do not change or damage any component
that may affect the safety and stability of
the machines.
11) Key part affecting the stability of the
machine shall not be replaced with part of
different Spec.
12) Ensure that all tires are in good condition
and the nuts are properly tightened. Do not
replace the original tire with a tire of
different Spec.
13) The ambient temperature for the use of the
machine shall be -20 ℃~ 40 ℃, and the
relative humidity should not be greater than
90% (at 20 ℃).
14) Ensure that this manual is kept in the file
box in the platform.
15) Total vibration value to which the hand/arm
system is subjected does not exceed 2.5
m/s². Highest root mean square value of
weighted acceleration to which the whole
body is subjected does not exceed 0.5 m/s².
1.9 Operating Hazards on
Slopes
Do not drive the machine on a slope that
exceeds the maximum uphill, downhill or side
slope rated value of the machine. Slope rating is
only applicable to machines in stowed state.
The maximum slope rating when the boom is
stowed is as follows
