Safety Precaution
Precautions of electric technician who use Medical Electronic Equipment
Warning:
● Strong magnetic components have been assembled on this vehicle.
● Technicians shouldn't operate electronic pacemaker or other medical electronic devices in this vehicle, or the functions of medical devices may be affected by strong magnetic components.
Precautions for normal charging
Warning:
●
If a technician uses a medical electric device
such as an implantable cardiac pacemaker or a
heart pacemaker/defibrillator, the effects of the devices must be checked
before starting the charge operation.
●
If a technician using a medical electric device
such as implantable cardiac
pacemaker or an implantable heart pacemaker defibrillator .he must not enter
the vehicle compartment (including luggage room) during normal charge
operation.
Communication equipment operation precautions
● If the technician uses medical electronic devices such as cardiac pacemaker, cardioverter or defibrillator and other medical electronic equipment, please keep enough distance with the communication devices.
● The electromagnetic wave of the remote intelligent terminal may affect the function of the medical device such as cardiac pacemaker, cardioverter, defibrillator and other medical electronic devices.
● If the technician uses the medical device such as cardiac pacemaker, multiplexer, defibrillator and other medical electronic equipment, the electromagnetic wave of the remote intelligent terminal may affect the function of the device. The possible effect of the remote intelligent terminal on the medical electronic devices must be checked by the manufactures of the medical electronic devices .
Inspection of key points before the maintenance
The high-voltage system may automatically operate. Please confirm the remote air conditioning and fixed-time charging haven’t been set before the maintenance.
Attention:
If remote air-conditioning or fixed-time charging is set, the high voltage system will run automatically even the switch is off.
Precautions of auxiliary restraint system "airbag" and "seat belt pretension"
The
Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”,
used along
with a front seat belt, helps to reduce the risk or severity of injury to the
driver and front passenger for certain types of collision. This system includes
seat belt switch inputs and dual front air bags. Information necessary to
service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of
this Service Manual.
Warning:
Always observe the following items for preventing accidental activation:
● To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized JAC dealer.
●
Improper maintenance, including incorrect
removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral
Cable and Air Bag Module, see “SRS AIR BAG”.
● Do not use any electrical test devices to test any circuit of the auxiliary restraint system unless these tests are in the instructions described in the service manual. The wire harness and connectors of the auxiliary restraint system should adopt to yellow or orange color.
Precautions when using power tools(pneumatic or electric) and hammer
●
When working near the Air Bag Diagnosis Sensor Unit or other Air
Bag System sensors with the power switch ON, never use air or electric power
tools or strike near the sensor(s) with a hammer. Heavy vibration could
activate the sensor(s) and deploy the air bag(s), possibly causing serious
injury.
● When using power tools or a hammer, turn the key in the "LOCK" position, unplug the cathode of 12V lead-acid battery and wait at least 1 minute for maintenance.
Precautions of removing the 12V battery
When removing the 12V battery, turn the power switch to “ON”, and then to “OFF”.
Note:
● The automatic 12V battery charge function may start even when the power switch is in “LOCK”state.
● The automatic 12V battery charge control does not start within approximately one hour when the power switch is turned ON/OFF.
● Before the repairing which no need the power: rotate the key to LOCK gear and disconnect the 12V battery negative.
● After disconnect the 12V battery negative, the memory of radio and other control devices will be cleared.
● Replace new oil seal, gasket,gasket ring,O-type ring,lock washer,cotter pins,self-locking nuts and other parts.
● Place the removed parts in order and according to the positions as they are assembled .
● If necessary, use approved binders, sealants or equivalent products.
● For safe and efficient repair work, you should use hand tools, power tools (disassembly only) and special tools.
● Before repairing the vehicle:
Cover the fender, interior and carpet with a suitable cover. Be careful do not scratch the paintwork with keys, buttons or something like this.
The below upgraded anticorrosion method has been realised in factory, same method is advised when repair or replace vehicle body.
Anticorrosion Painting layer steel
A new kind of anticorrosion Painting layer steel uses
zinc-coated thin steel plate instead of traditional coated plate, improving the
capability of remedy and anticorrosion ability. Zinc-coated steel is kind of
Zn-Fe alloy made from electroplate and heating, providing good and long-term
anticorrosion ability and uses cationic electricity sedimentary paint.
Phosphate coating disposal and cationic electricity
sedimentary paint
Chromating and cationic electricity sedimentary paint provide good
anticorrosion protection and applicable for all vehicle body.
Note: minimum damage to paint is a must during welding
undercoat
Undercoat of floor and cabin is to be against corrosion/vibration/noise and stones bumping, so repair is to use the plate after same process, using inner paiting layer is a part of undercoat of anticorrosion/ sound insulation/ anti vibration/ impact.
Precautions:
● Do not paint the undercoat everywhere unless it is regulated area;
● Do not paint around the exhaust pipe, influencing heat dissipation effect;
● Do not paint at rotating part;
● Paint green wax after painting the undercoat;
● After painting the vehicle body sealant, paint the undercoat.
Stone splash protection
To prevent the damage from stone, lower floor(mud guard/ door, etc.) will be painted with a layer of undercoat. When replacing or repairing these panels, same materials should be used as anti stone crash. This material should be with functions including anticorrosion/ strong durable/ impact resistance/ long warranty, etc.

Below diagram shows, sealant is commonly used at smooth place without cutting or gaps in the factory sealing area. But sealant can’t be used too much, and touch is not allowed to sealant by other no-need-sealing area.
