1.8 Safety of Work Area
1) The platform can only be raised on a solid
and flat level ground.
2) The speed shall not exceed 0.5km/h
/0.31mph when the platform is raised.
3) The inclination alarm cannot be regarded
as level indicator. When the machine is
seriously inclined, the inclination alarm of
the chassis and platform will ring.
4) If inclination alarm rings, lower the platform
and move the machine to a solid level
ground. If the inclination alarm rings when
the platform is raised, the platform shall be
lowered very carefully.
5）In case the machine is used outdoor, do not
lift the platform when the wind speed is
above 12.5m/s /28mph if the wind speed
exceeds the limit after lifting the platform,
please immediately lower the platform
and stop the machine operation.
6）Do not operate the machine in strong winds
or gusts. The surface area of the platform
or load cannot be increased. Increase of
the area exposed to the wind will reduce
the stability of the machine.

7）In the raising state of the platform, the
machine cannot run on uneven terrain and
unstable surface, or in other dangerous
situations, or near these areas.
8）In the stow state, the machine must run very
carefully and reduce its speed when it
runs on uneven terrain, unstable or
smooth surface with stones, or the place
near the tunnel, or the steep slope.
9）Do not use the platform control unit (PCU) to
release the platform when the platform is
tripped, stuck, or its normal operation is
obstructed by other nearby matters. Before
using the ground control unit (GCU) to
release the platform, all staff must leave the
platform.
10）Don't push or pull anything outside the
platform.
11) Don't use the machine as a crane.
12) Don't place, fasten and fix or suspend loads
on any component of the machine.
13) Don't place ladders or scaffolds within the
platform or against any component of the
machine.

guardrail.
18) Don't change or damage any component
that may affect the safety and stability of
the machine.
19) Don't replace key parts that affect machine
stability with parts of different weights or
specifications.
20) Don't amend or modify the mobile elevated
work platform. Install additional equipment
for placing tools or other materials on
platforms, pedals or guardrails, which will
increase platform weight and surface area
or load.
21) Don't push machines or other objects on
the platform.
22) Only transport tools and materials that are
evenly distributed and can be safely moved
by people on the platform.
23) Don't use machines on moving surfaces
and vehicles.
