Safety Precaution

the electrical technicians who use medical electronic devicesprecautions

Prohibit Operation

Warning:

1       Strong magnetic components have been assembled on this vehicle

2       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:

3       If a technician uses a medical electric device such as an implantable cardiac pacemaker or an

implantable heart pacemaker defibrillator, the possible effects on the devices must be checked  before starting the charge operation.

4       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, 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 stage front air bag modules. 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.

1       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.

2       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”.

3       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 (AIR OR ELECTRIC) AND HAMMERS

         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:

1       The automatic 12V battery charge control may start even when the power switch is in OFF state.

1       The automatic 12V battery charge control does not start within approximately one hour when the power switch is turned ON/OFF.

 

Matters needing attention

1       Before the repairing which no need the power: rotate the key to LOCK gear and disconnect the 12V battery negative.

2       After disconnect the 12V battery negative, the memory of radio and other control devices will be cleared.

3       Replace new oil seal, gasket,gasket ring,O ring,lock washer,cotter pins,self-locking nuts and other parts.

4       Place the removed parts in order and according to the positions as they are assembled .

5       If necessary, use approved binders, sealants or equivalent products.

6       For safe and efficient repair work, you should use hand tools, power tools (disassembly only) and special tools.

7       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.
