HAZARDS
UNSAFE JOBSITE HAZARDS
• Do not operate the machine on
surfaces, edges or potholes that
cannot bear the weight of the
machine. Raise or extend the
platform only when the machine is
on firm, flat ground.
• Do not use the tilt alarm as a
horizontal indicator. The tilt alarm
on the platform will sound only
when the machine is heavily tilted.
• If the tilt alarm sounds while lifting
the platform, be very careful when
lowering the platform. Do not
change the level or limit switch.
• Drive speed should not exceed 1.1
km/h (0.68 mph) when the
platform rises.
• If the machine can be used
outdoors, never operate it during
strong winds or gusts. Do not lift
the platform when the wind speed
exceeds 12.5 m/s (28 mph). If the
wind speed increases to beyond
12.5 m/s (28 mph) after the
platform is lifted, retract the
UNSAFE JOBSITE HAZARDS
platform and stop operating the
machine.
• Never use any devices that may
increase the wind load on the
machine.
• Never travel on uneven terrain or
unstable surfaces or in other
dangerous conditions when
raising the platform.
• With the machine retracted, be
careful and slow down when the
machine is moving on uneven
terrain, crushed stone, unstable
or slippery surfaces, steep slopes
and near cave entrances.
• Do not drive or lift the machine on
slopes, steps or vaulted surfaces
that exceed the maximum
climbing capacity of the machine.
Before or during machine operation, check the jobsite
for potential hazards and pay attention to the
environmental limitations, including potentially
flammable and explosive gas/dust. If the machine is to
be used in any other applications or by any other
means other than those specified by Sinoboom, it
must be approved or guided by the manufacturer.
