1 General 1-7 Warnings and Notices 1.2.2 Precautions for maintenance operation safety Precautions for maintenance operation safety: - When repairing high voltage parts of vehicle, a full-time supervisor must be allocated. And the supervisor and maintenance personnel must have the national accredited Special Operation Certificate (Electrician) and Primary electrician certificate (including) or above (professional qualification certificate). - The supervisor will supervise the whole process of maintenance.
-Supervise whether the composition of maintenance personnel, use of tools, wear of protective equipment, safety protection of spare parts, and maintenance safety warning sign meet the requirements. - Check whether the high voltage load equipment (such as the IPU) has high voltage. - Responsible for the inspection of the safety maintenance operation procedures in the maintenance process. The supervisor should direct the operation according to the safety maintenance operation procedures, be informed after the maintenance personnel finishes an operation, and mark on the job instruction sheet (JIS).
- Untrained personnel are prohibited to carry out high voltage parts maintenance, and all personnel are prohibited to carry out dangerous operations with fluke mentality to avoid safety accidents. - Do not reuse the dropped high voltage battery. Excessive collision may lead to damage and breakage of parts inside the high voltage battery, or even short circuit of the high voltage battery and other extreme situations. - Prevent the high voltage battery from being soaked, which may lead to internal short circuit, loss of circuit protection function and abnormal chemical reaction of the high voltage battery.
- Do not bump or hit the high voltage battery during assembly to avoid deformation of the housing and its internal structure, which may lead to loss of protection function of the internal circuit of the high voltage battery. - Welding on the housing is prohibited. The applied voltage to the high voltage battery may cause the loss of protection function of its internal circuit. - This manual does not necessarily include all items required for vehicle repair and maintenance. It is intended for use by personnel with professional skills and qualifications.
Repair or maintenance performed by technicians who have no professional skills or qualifications and rely only on this manual or fail to use appropriate equipment or tools, will cause injury to themselves or the surrounding personnel and damage to customer's vehicle. To avoid damage to vehicle as a result of dangerous operations, please observe the following rules: - The contents of this manual must be read thoroughly. - The methods provided in this manual are quite effective for vehicle maintenance and repair. When performing repairs following the procedures prescribed in this manual, always use the SST.
In the event of using non-designated special tools and repair methods, you must ensure the safety of the technician before start and make sure no personal injuries or damages to customer's vehicle will be caused. - If parts need to be replaced, replace parts with the same part number and do not use inferior parts. - In order to effectively avoid possible personal injury during repair or maintenance, as well as vehicle damage caused by improper operation or potential hazards that may make the vehicle unsafe, you must earnestly observe the “Warning” and “Notice” in this manual. In addition, the contents of “Warning” and "Notice" in this manual are not exaggerated.
Violation of these instructions may lead to dangerous consequences. - The vehicle is equipped with a power system that operates at high voltage. All related operations of the high voltage system (e.g. maintenance, repair of the electrical system) can only be performed by professionals trained in high voltage electrical knowledge. - For vehicles with air suspension, any vehicle lifting operation (for inspection, repair, maintenance, etc.) needs to switch the vehicle active suspension mode to maintenance mode, otherwise it may damage the air suspension. Important precautions for filling brake fluid in brake system CAUTION:
- When filling brake fluid in the brake master cylinder reservoir, only brake fluid in clean and sealed containers should be used. The fluid meets the DOT4 requirements. Failure to use the recommended brake fluid will result in system contamination that can damage rubber seals or rubber gaskets inside hydraulic brake system components. VOYAH FREE
