2.3 OPERATION SAFETY

IMPORTANT SAFETY RULES
GTJZ0608E&0808E Operation Manual 7©April 2023
General
• This machine shall only be used
to transport tools to work loca-
tions and for performing tasks on
the work platform, and should not
be used for other purposes.
• Operators should use personal
fall protection equipment (PFPE)
while operating the machine. If
workplace or other rules require
the use of PFPE by persons on
the platform, the PFPE should be
inspected and used in accordance
with the PFPE manufacturer’s in-
structions and applicable govern-
ment requirements.
• The operator must devote their
full attention to their work during
the operation of the machine. The
use of mobile phones, wireless
communication devices, etc. may
distract the operator and affect
the safe operation of the machine,
so the operator should completely
stop the machine before using
such devices.
• Remove all rings, watches and
other accessories before operat-
ing the machine, do not wear
loose clothing, and do not let long
hair hang loosely.
• Individuals who have consumed
alcohol or taken medication, who
are overly fatigued or mentally
distressed, who suffer from health
conditions such as heart disease,
high blood pressure, epilepsy,
etc., individuals with a fear of
heights or who feel unwell are pro-
hibited from operating the
machine.
• Do not operate a damaged or mal-
functioning machine. In case of
any failure, stop the machine im-
mediately, label the machine ap-
propriately, and contact the
manufacturer or relevant
department.
• Never disassemble, modify or ret-
rofit the machine or its parts.
• Never disable any safety devices
of the machine.
• Never place objects on the plat-
form guardrails.
• Never push the control switch or
joystick forcefully through the
neutral position directly into the
opposite direction. Before push-
ing the switch to the next function
position, move it back to the neu-
tral position and stop, and then
move it with slow and uniform
force to perform the next function.
• Except in case of emergency, it is
forbidden to perform operations
from the ground if any person is
still on the platform.
• When there are two or more peo-
ple on the platform, all operation
of the machine must be con-
ducted by the operator.
• Always operate the machine in
well-ventilated conditions to avoid
carbon monoxide or nitrogen ox-
ide poisoning.
• Before leaving the machine, the
platform should be completely
lowered and all power should be
shut off.

© April 2023 8GTJZ0608E&0808E Operation Manual
IMPORTANT SAFETY RULES
Electrocution Hazard
• This machine is not insulated and
not equipped with electrocution
protection function.
• Do not use this machine during
thunderstorms or heavy rain.
Should you encounter thunder-
storms or heavy rain while operat-
ing the machine, immediately
lower the platform completely to a
safe and stable position, and dis-
connect all power sources so as
to avoid personal injury or ma-
chine damage.
• Comply with the national or re-
gional provisions covering mini-
mum safe distance from live
conductors. In absence of such
provisions, comply with Page 8,
Table 2-1 Minimum safe distance
to keep a minimum safe distance
from power lines, electrical equip-
ment or any live (bare or insu-
lated) components. The minimum
safe distance shall be determined
with machine movement, electric
wire swinging or drooping
considered.
• If rated insulating barriers appro-
priate to the voltage of electric
wire are installed, the minimum
safe distance can be shortened.
Such partitions may not be part of
the machine or fixed on the ma-
chine. The reduction in the mini-
mum safe distance due to
insulating partitions must comply
with the relevant national or local
regulations.
• Do not use the machine as a
ground wire during welding and
polishing operations.

restricted areas with live electrical equipment.
Tripping and Fall Hazards
• Before operating the machine, en-
sure that the platform guardrails
are properly installed and that the
platform gate is closed and prop-
erly secured.
• Operators on the platform must
wear the safety belt properly and
secure the safety belt to the speci-
fied anchorage point with the
hook. Each fixing point shall only
be used by one person.
• Only enter and exit the platform
through the platform gate, never
through the scissor, and extra
care should be taken. Before en-
tering and exiting the platform,
make sure the platform is fully
lowered. When entering and exit-
ing the platform, face the platform
and maintain three points of con-
tact with the machine, with both
hands and one foot or both feet
and one hand.
• Both feet must be securely placed
on the platform floor at all times. It
is forbidden to sit, stand or climb
on the platform guardrails.
• Never use ladders, boxes, steps,
boards, or similar items on the
platform to extend your reach.
• Do not allow oil, sludge or other
slippery substances to remain on
work shoes and platform floor.
• Keep the platform floor
unobstructed.

IMPORTANT SAFETY RULES
GTJZ0608E&0808E Operation Manual 9©April 2023
Tipping Hazard
• Before driving the machine onto
any ground, bridge, truck or other
surface, check if the loading ca-
pacity of the surface is sufficient
to support the machine (machine
weight + platform load). Do not
drive the machine on any surfaces
or edges that are not capable of
fully supporting the machine.
• Operators must familiarize them-
selves with the ground conditions
of the work area before commenc-
ing work.
• Do not operate the machine on
moving surfaces or vehicles.
• The total weight of personnel, de-
vices and materials on the plat-
form shall not exceed the
maximum carrying capacity of the
platform, and all loads shall be
kept within the specified range of
the platform.
• It is forbidden to drive the ma-
chine on slopes, steps or arched
surfaces that exceed the maxi-
mum allowable climbing angle of
the machine.
• Do not use the tilt alarm as a hori-
zontal indicator. The tilt alarm on
the platform will sound only when
the machine is heavily tilted.
• When the platform is raised, if the
tilt alarm sounds, lower the plat-
form carefully, and do not modify
the level switch or limit switch.
• When the platform is raised, do
not drive the machine on uneven
or soft surfaces, or slopes that ex-
ceed the maximum allowable
climbing angle of the machine, or
in other dangerous conditions.
• The platform can only be raised
or extended when the machine is
on solid, flat ground.
• When the machine is traveling on
uneven ground, or on other rough
ground with gravel, or near cave
openings, steep slopes, etc., be
careful and reduce the speed.
• Do not push or pull any objects
outside the platform.
• Never push or pull other equip-
ment or objects with the platform
or scissor arm.
• Do not place or attach any sus-
pended load on or to any part of
the machine.
• Do not place any load outside the
perimeter of the platform.
• Using the machine as a hoist or
crane is strictly prohibited.
• Never attach the machine or its
parts to any adjacent objects.
• Do not operate the machine while
the chassis box is opened.
• When one or more tires are off
the ground, first evacuate all per-
sonnel and then stabilize the ma-
chine with cranes, hoists,
forklifts, or other suitable
equipment.
• Without written authorization of
the manufacturer, it is forbidden
to modify, remove or install any
parts, including counterweights,
which may affect the safety and
stability of the machine.
• Do not replace critical parts that
affect the stability of the machine
with parts of different weight or
specifications. For example, bat-
teries not only provide power, but
also serve as a counterweight,
and are crucial for maintaining the
stability of the machine.
• If the machine can be used out-
doors, do not operate the machine
when the wind speed exceeds
12.5m/s (28mph) (including gust).
Please check the Beaufort wind
force scale in Page 10, Table 2-2 .
Factors that affect wind speed in-
clude: platform height, surround-
ing terrain, local weather. For
example, the wind speed at high
places may be much faster than
those on the ground.

© April 2023 10 GTJZ0608E&0808E Operation Manual
IMPORTANT SAFETY RULES
• Wind speeds might change at any
time. The upcoming weather con-
ditions, the time required to lower
the platform, and ways to monitor
current and potential wind condi-
tions must always be considered.
• When operating the machine out-
doors, do not carry items with a
large surface area on the platform,
do not cover the surface of the
platform or load, and never use
additional items to increase the
surface area of the platform or
load. Adding such additional
items will increase the exposure
of the machine to the wind. In-
creasing the windward area will
lead to reduced machine stability.
