! CAUTION: The effects of strong
winds or gusts on the movement of the
platform, the swinging and slackening
of the wires shall be taken into
account.
1) If the machine comes into contact with a
live wire, get away from the machine
immediately.
2) Personnel are prohibited from touching or
operating the machine before cutting off the
power to the wires.

3) If the platform is overloaded, the buzzer will
alarm. Please reduce the platform load first.
4) When the platform is lifted, the driving
speed should not exceed 0.8 km/h
(0.5mph).
5) The tilt angle sensor cannot be used as a
level indicator. The buzzer on the turntable
will only sound when the machine is heavily
tilted.
6) Please be very careful if the buzzer sounds
when the platform is lifted. The machine's
non-level indicator will light up and the drive
function will not work in either direction.
First determine the status of the upper
boom on the slope, as shown below. Then
follow the steps below to descend the boom
before moving the machine to a solid and
level ground. Do not rotate the boom when
descending.
If the buzzer sounds when the platform goes up
the slope
①Lower the boom
②Retract the boom
If the buzzer sounds when the platform goes
down the slope
①Retract the boom
②Lower the boom
7) Do not lift the boom when the wind speed
may exceed 12.5 m/s (28mph). If the wind
speed exceeds 12.5 m/s (28mph) after the
boom is lifted, lower the boom and do not
continue to operate the machine.
8) Do not operate the machine in strong winds
or gusts. 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) Do not use the upper control box to operate
the machine when the platform is trapped,
jammed, or other objects nearby are
blocking its normal movement. If you plan
to operate the machine with the lower
control box, all personnel must leave the
platform before you do so.
10) In the retracted state, please be very
careful and reduce the speed when the
machine is running on gravels, unstable or
smooth surfaces and near the entrance of
the cave or steep slopes.
11) When the boom is lifted, the machine
cannot run on uneven terrain, unstable
surfaces, or other dangerous conditions, or
run near these areas.

slope.
1.8 General Safety
1) Do not operate the machine with the hood
open.
2) Do not allow the boom to approach or touch
anything.
3) Do not change or use all sensors such as
length transducer, tilt angle sensor, the
weighing sensor and rope-breaking
detection devices.
4) Do not bundle the boom or platform to
adjacent objects.
5) This machine shall not be modified without
the prior written permission of the
manufacturer. Additional devices installed
on platforms, pedals or guardrails for
placing tools or materials will increase the
weight and surface area of the platform.
6) Do not place ladders or scaffolds 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 the machine on moving surfaces
or vehicles.
9) Do not place your hands and arms near the
area where there is a risk of cutting or
crushing.
10) Do not alter or damage any parts that may
affect the safety and stability of the
machine.
11) Do not replace parts that affect machine
stability with parts of different specifications.
12) Ensure that all tires are in good condition
and the nuts are properly tightened, and do
not replace the original tires with tires of
different specifications.
13) The ambient temperature of the machine is
-20 °C ~ 40 °C.
14) Ensure that this manual is kept in a file box
in the platform.
1.9 Danger of Operating the
Machine on Slopes
Do not drive the machine on slopes exceeding
the machine's maximum uphill, downhill or side
slope ratings. The slope rating applies only to
machines that are in the retracted state.
