Cautions

Preventive measures for electrical technicians using medical electrics

Forbidden operation

Warning:

●     There is strong magnetic components on this 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 .

Key points checking before maintenanc

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

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 steering system maintenance

●     When tightening the fixing bolt, vehicle shall be unloading and on the road, then check wheel alignment.

●     Cautions for removing steering assembly

1     Please clean completely outside of steering assembly before disassembly.

2     Please dismantle in a clean working space to avoid the internal components from dust or other foreign body contamination.

3     Please put the parts on the parts rack in order after dismantling.

4     Clean components with nylon fabric or paper cloth .  ordinary cloth will have residual chip cloth affecting parts operation.

5     Forbidden to reuse the components which couldn’t be used again.

6     Please grease the designated parts before assembly.

●     When quick play steering wheel,  could hear the noise around steering wheel, which is the voice of the steering control system to work normally. If in the process of slowly turning the steering wheel, appear harsh noise, which is the abnormal phenomena. If necessary, please repair.

●     Forbid to continuous steering in the same place.

●     when disassembling parts of steering system (steering column 、 EPS controller, steering shaft, steering gear), must let the steering angle of steering system be zero, otherwise, the vehicle will appear badly turn back and active partial problem.

Check

Check middle position of steering wheel

1     Confirm  the correct installation position of the steering assembly, steering column assembly and the steering wheel.

2     After wheel alignment, execute the middle inspection.Please see “the front suspension - wheel position ".

3     Parking vehicles, wheels go straight on, and make sure the steering wheel in the middle position.

4     If the steering wheel is not in the middle, please loosen the tie rod rod fine-tuning lock nut and turn right or left.

Check steering force of steering wheel

1     Vehicles parked in a horizontal dry ground, the wheels straight forward and pull the parking handle.

2     Confirm the pressure of the tire value should be within the scope of the standard value. Please see the "wheel - wheel assembly"

3     Place the vehicle on “READY” status.

4     Rotate steering wheel for 360 ° from the middle position, check the steering wheel steering force, and whether steering force has obvious fluctuation.

Steering force of steering wheel:<25N  allowed fluctuation:<5N

L: 187.5mm


Caution:

If the steering wheel steering force is more than specified value, please check or adjust the following items:

●     Whether steering rod ball head is damaged.

●     Preloading of steering assembly gear and rotational torque of steering rod ball head , Please see the " steering system-steering assembly”

Check steering angle of front wheel

1     Check front wheel hub and detect steering angle of front wheel.

2     Place the front wheel on the steering angle measuring device (front wheel positioning steering wheel ), The vehicle is in the "READY" status, turn the steering wheel left and right to the limit position,measure the largest wheel inner and outer steering angle.

Steering angle of inner wheel(angle A):35.1°±1.5°

Steering angle of outer wheel(angle B):30.6°±1.5°

3     If the measured value is not in the standard range, please check the following item.

 

Steering gear stroke

Gear stroke standard value:67±0.5mm

If gear stroke surpass standard value, please replace steering assembly.

Caution:

Inner and outer wheel steering angle couldn’t be adjusted. If steering angle is different with the specified value, please check the steering gear assembly, steering column assembly and front suspension parts for wear or damage. If yes, please replace.


Learning process for steering angle of steering system to be zero

1     Put vehicles in the four-wheel positioning device to ensure qualified parameter adjustment of vehicle four-wheel positioning .

2     Adjust wheels to be straight forward and assure the steering wheel is in the middle( angle with the horizontal within0.5°) 

3     Let the diagnostic instrument connect with OBD interface, the key is in the "ON" state, choose EPS calibration data in the diagnostic instrument , set the vehicle steering angle as zero, calibrate the middle position of steering wheel as zero position of  steering system of EPS controller.

4     After set the steering angle as zero, please test drive and confirm, when turning back at low speed  (≥10 km/h), the steering wheel can back near the middle. At the same time to ensure that the car travels in a straight line, there is no active partial problem, otherwise it is needed to check vehicle steering system again.
