Unsafe operation hazard
After the connector is repositioned, the
manual release valve must be closed in
time, otherwise it may lead to serious
personal injury or death.
Connector tilted forward
Figure 6-9 Connector tilted forward
Tipping hazard
If the connector tilts forward and the
platform is raised, retract and lower the
main boom until the platform reaches
the ground. Do not use the machine
until the connector is restored to its
normal state.
The connector may be tilted forward in a few cases,
and repositioning forward-tilting connector is
complicated, which is not described in this manual. In
case of forward tilt, contact Sinoboom or a service
technician approved by Sinoboom immediately to
reposition the machine.
