materials on the platform shall not
exceed the maximum load
capacity.
• Only raise or extend the boom
when the machine is on solid,
level ground.
• Select only the low speed when
driving the machine on a slope.
• Do not use the tilt alarm as a level
indicator. The tilt alarm on the
platform will sound only if the
machine is heavily tilted.
• If the tilt alarm sounds when the
machine drives up a slope, please
lower the boom per the following
procedure and move the machine
onto firm level ground. Be sure
not to rotate the boom when
lowering.
1. Lower the main boom;
2. Lower the articulated boom;
3. Retract the telescopic boom.
• If the tilt alarm sounds when the
machine drives down a slope,

the platform when the wind speed
exceeds 12.5 m/s (28 mph). If the
wind speed exceeds 12.5 m/s (28
mph) after the platform is lifted,
retract the platform and do not
continue to operate the machine.
• Do not use any devices that may
increase the wind load on the
machine.
• Do not drive or lift the machine on
slopes, steps or vaulted surfaces
that exceed the maximum
gradeability of the machine.
UNSAFE JOBSITE HAZARDS
• Do not lift the machine and drive
the machine sideways on slopes
greater than 5°.
Before or during machine operation, check the jobsite
for possible hazards and pay attention to the
environment restrictions, including flammable and
explosive gases/dust. If the machine is to be used in
any special workplace or work method other than those
specified by Hunan Sinoboom Intelligent Equipment
Co., Ltd., the manufacturer’s approval and guidance
should be obtained first.

NOTICE
Maximum gradeability is applicable for machines with
platform retracted. The maximum gradeability: 40%/
21°.
Gradeability means the maximum allowable tilt angle
of the machine when it is on solid ground and the
platform is only carrying one person. As the weight of
the machine’s platform increases, the machine’s
climbing capacity wil be reduced.

UNSAFE OPERATION
HAZARDS
At a minimum, operators must operate and maintain the
machine as stated in the Operation Manual and the
Maintenance Manual in addition to following more
stringent industry regulations and workplace rules.
Do not use the machine in the following situations:
•Unrelated personnel/equipment is present in the
working envelope of the machine.
•Use as a crane (except the custom-made ones with
such function).
•Use on the truck, trailer, tracked vehicle, ship,
scaffold and the like without written consent by the
manufacturer or a qualified professional.
•Improper securing of the machine to another object
by just sitting it against, fastening or binding.
•Stunt or imprudent use of the machine.
•Overloaded or over-moment situation.
•Other prohibited situations as specified in the
Operation Manual.
UNSAFE OPERATION HAZARDS
• Do not push any object outside
the platform. The maximum
lateral force allowed is 400N (90
lbf).
• Tow the machine only from the
tie-down/lifting points on the
chassis.
• Never use the boom or platform
to stabilize or support any
objects outside of the machine.
• Do not modify any component
that may affect the machine
safety and stability.
• Do not replace key parts that
affect machine stability with
parts of different weights or
specifications.
• Do not change or modify
moving aerial platforms without
the manufacturer’s written
permission.
• On the platform, do not attach
an additional device for placing
tools or other materials to the
guardrail. This will increase the
platform weight, surface area
and load.
• Do not put ladders or
scaffolding on the platform or
against any part of this
machine.
• Do not use additional devices
to increase the working height
of the machine.
• Do not use the machine on any
mobile or movable surface or
vehicle. Ensure all tires are in
good condition, the slotted nuts
tightened and the cotter pins
complete.
• Do not use a battery that
weighs less than the original
one (25kg [55 lb]), and do not
remove or modify the
counterweight or other parts
inside the battery box. The
battery not only provides
power, but also serves as a
counterweight. The battery is
vital to maintaining the stability
of the machine.
