UNSAFE JOBSITE HAZARDS
• If the machine can be used
outdoors, never operate it in
strong or gusty wind. Do not lift
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 raised,
lower the platform and stop
operating the machine.
• Do not use any device that may
increase the wind load on the
machine.
• Do not drive or lift the machine on
slopes, steps or vaulted surfaces
UNSAFE JOBSITE HAZARDS
that exceed the maximum
gradeability of the machine.
• Do not lift the machine and drive
the machine sideways on slopes
greater than 5°.
Before or during the operation of machine, check the
jobsite for possible hazards, and pay attention to
environmental restrictions, including flammable and
explosive gases/dust. If the machine is to be used in
any special workplace or by any special 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 climbing angle of
the machine: 45 %/24° (4WD) & 30 %/17° (2WD).
Gradeability refers to 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 will be decreased.
GRADEABILITY:
Uphill:
45 %/24° (4WD)
30 %/17° (2WD)
