Cautions for electric technicians using medical electrics
Forbidden operation
Warning:
● There are strong magnetic components in the vehicle
● If technician use medical electrics,e.g electronic pacemakers, which couldn’t be operated in the vehicle ,otherwise,the function of electrics may be effected by strong magnetic components.
Cautions for normal charge
Warning:
● If technician use the medical electrics like pacemakers, cardiovascular, in addition to the top, the machine only could be used after the function of machine checked and confirmed before normally operation.
● In the normal charging operation, Medical electrics may be affected by electromagnetic wave. When Technicians use the medical electrics like pacemakers, cardiovascular, in addition to the top etc, it is not allowed to enter into crew capsule (including luggage).
Cautions for communication equipment
● If technicians use the medical electrics like pacemakers, cardiovascular, in addition to the top etc, please keep enough distance with the communication equipment.
● Remote intelligent terminal of electromagnetic waves may affect the function of the medical electrics like pacemakers, cardiovascular, in addition to the top etc.
● If technicians use the medical electrics like pacemakers, cardiovascular, in addition to the top etc, remote intelligent terminal of electromagnetic waves may affect the function of the medical electrics. It is needed to let the manufacturer of the medial electrics confirm that the possible affection to medical electric equipment when using remote intelligent terminal .
Keypoint checking before maintenance
High pressure system can be run automatically, it is need to confirm that remote air conditioning and recharged regularly are not set before maintenance.
Cautions：
● If set remote air-conditioner or charged regularly, even though the switch is closed, high pressure system can be run automatically.
Cautions for "safety airbag"and"safety belt preloaded"of auxiliary constraint system
The combination use of "safety airbag"and"safety belt preloaded"of auxiliary constraint system and front seat belt could decrease the damage to driver and passengers when collision. The auxiliary constraint system include seat belt, airbag for driver, airbag for co-driver. The detailed information for auxiliary constraint system could refers to the sections of “airbag system” and “seat belt”
Warning:
To avoid unexpected accident, we need to obey the following:
● To avoid the auxiliary constraint system invalid, all the maintenance only could be operated by JAC authorized distributors because the risk of injury to people will be increased after invalid.
● Non-standard auxiliary constraint system of maintenance including non-standard disassembly and installation, may result in auxiliary constraint system accident triggered, causing personal injury accidents. About remove the airbag module method, please see "airbag system" section.
● In addition to the maintenance instructions in the manual operation, do not use electrical test equipment to test any circuit of auxiliary constraint system. Auxiliary constraint system of connectors and wiring harness use yellow or orange color.
Cautions when use electrical tools (pneumatic or electric)and hammer
● when electric switch in the "ON" block, near the airbag diagnostic sensors or other sensor, do not use power tools or hammer to operate sensor parts area. Severe vibration may activate the sensor, some airbags, causing serious damage.
● When using power tools or hammer, put the keys in the "LOCK" block, unplug the 12 v lead-acid battery cathode, waiting at least 1 minute, then for checking and maintenance.
Cautions for removing 12V battery
Turn the key to “on”,then to “lock” before remove 12v battery
Tip:
● Even if the key in the "LOCK" and the 12 v battery charging function may start automatically.
● After turn the key to "ON" --> "LOCK", 12 v battery automatic charging will not start.
Cautions for checking and maintenance suspension system
● It shall thoroughly check before repair or replacement parts.
● Check fastening parts torque after installation.
