INTRODUCTION
Thank you for choosing and using the machinery of
Hunan Sinoboom Intelligent Equipment Co., Ltd. Al-
ways read, understand and become familiar with the
operation requirements of the machine and its associ-
ated safety procedures before operating, maintaining
and repairing the machine. Operating the machine with-
out becoming familiar with its specific operation require-
ments and safety procedures poses serious risks.
Operators who follow safety rules and operate the ma-
chine carefully and effectively will prevent personal in-
jury, property loss and accidents.
Use this machine only to transport tools to work loca-
tions and for performing tasks on the work platform. Op-
erators must be competent and must obtain training to
carefully use the machine and follow safety procedures.
Only trained and authorized personnel may operate the
machine.
This manual guides the operator and authorized per-
sonnel in maintaining the machine. The operator is re-
sponsible for reading, understanding and implementing
the maintenance and safety procedures in this manual
and for following the manufacturer’s instructions before
beginning any work. Read, understand and follow all
safety rules and operating instructions. The operator
must also consider the machine’s uses and limitations
and the conditions at the jobsite before using this ma-
chine. Strictly following all safety requirements in this
manual is critical.
Consider this manual a part of the machine, along with
Operation Manual and Parts Manual, and always keep
the manuals with the machine. The owner or adminis-
trator of the machine shall offer all manuals and other
necessary information provided by the machine manu-
facturer regarding the daily inspection and maintenance
to each of the renters. If the machine is sold, the owner
or administrator must pass along the manuals and other
necessary information to the purchaser. The owner or
administrator of the machine shall also provide the
manufacturer’s maintenance information to the person
responsible for maintaining the machine.
If you have any questions, contact Hunan Sinoboom In-
telligent Equipment Co., Ltd..
