CHAPTER 4 Operations method and considerations

I . Considerations for safe driving

1. Please observe traffic regulations and drive safely. Please control the speed within safe speed range.

2. Before driving, read these instructions first, and then perform exercise at an open site, make sure you are fully mastering the driving and get familiar with the structure and performance of this vehicle.

3. Do not lend the vehicle to a person who is not familiar with or unable to drive the vehicle.

4. Take more care when driving in rain or snow, danger may occure due to wet ground. Then you should drive at a lower speed and take more care when turning. You must remember that you do have to brake earlier in rain or snow do to longer braking distance to prevent accidents!

5. Wear a helmet and fasten it correctly.

6. Wear suitable clothing: do not wear tights so that your whole body can move freely; you should wear clothing with sleeves unopened and low-heel shoes, as practical as possible.
   Note: in order to facilitate maintenance, repair and service, everyfatbike has a frame size and motor number, to help sales units to provide you with better service. Inscribed on the base plate of the fatbike you will find chassi number, machine number is ingraved on the motor shell cover.

7. Do not overload: the max is 180kg. The handling feeling of handlebar with load is different from that without load. When many articles are loaded, the handlebar will vibrate, resulting in danger. The stable load of the vehicle is one or two persons, it is very dangerous to load articles or person at the front of foot plate.

II . The correct method of use

1. The driving method

2. Keep natural posture, and free driving can be good.

3. Driving in sitting posture: please always keep your body at the center of the cushion to prevent load reduction of the front tire and danger caused by handlebar vibration.

4. Driving in standing posture: when speed up, you should turn the turning handles slowly, danger caused by instability due to sudden speeding-up should be avoided..

5. Drive the vehicle slowly on roads with surface damage or paved with gravels.

6. In rain or snow, wet ground will easily cause sideslip, so you should drive slowly with much attention. When water accumulated on roads becomes above the cell box located underneath the footplate, do not drive in it, so as to prevent electrical parts damage caused by short circuit. Meanwhile braking performance will decrease, which will cause accidents easily.

7. The way of parking

8. When parking , please pay attention to those vehicles and pedestrians around, park it to the right side of a flat road slowly, do not park it on a slope.

9. After parking it stable, turn the power supply lock rightwards to pull the key out and take it down, and then lock the scooter with a lock.

10. The power indicator method of use
    Turning on the power supply voltage indicator, you see 3 Led-lights, HIGH light, you have up to 75% of the rated capacity, HALF light charge is 25% of the rated capacity, LOW light flashing indicates that power is less than 10%, so when you find LOW lights flashing charge immediately.

11. The use of the power lock
    After the key of the power supply lock is turning by a shift in clockwise direction for connection, the motor can be started up. During driving, you do not remove the key and switch off power supply, nor can you turn the key in counter clockwise direction to close the power supply lock. Once you switch off the power supply, the motor will stop running, after parking, you should turn the power supply lock in counter clockwise direction to switch off the power supply, and then pull the key out.

12. Turning handle (speed)
    If the turning handle is turned towards the driver, the scooter will be speeded up, and if it is released to turn back the speed will be reduced, after reset, cut off the power supply of motor.

13. The use of the disc brake method and considerations:

14. The use of the disc brake

15. Brake clearance adjustment, turning the adjusting screw which is located between the braking handle and the handlebar tube using a 2mm Allen wrench, adjust the clearance between braking pads and the braking disc until your hands are comfortable.

16. Replace the braking pad when braking pads are worn out by more than 1mm or the adjusting screw of braking pads are adjusted to the end position or every 6 months. When replacing braking pads, press in one of the braking pads using a clean slotted screwdriver to vacate space for taking out the other braking pad. After replacement is complete, it is needed to return the adjusted screw of braking pads to a suitable position.

17. Run-in period: the run-in of disc brake surface needs a certain time, after complete run-in, braking force will increase significantly, the first week in which you use a new disc brake is the run-in period, do not brake with too great a force, otherwise unrecoverable damage will be caused to braking pads and braking body, the correct operation method is to brake slightly during driving, so that there is appropriate friction kept between braking pads and the disc brake.

18. Oil replacement: this disc brake adopts mineral oil, which should be replaced every (2-3) years in general when the baring handle feals weak, replace oil using an injector.

19. The matters needing attention

20. Do not use lubricating oils around the disc brake and braking pads, as well as the calliper, do not touch the surface of disc brake and braking pads with hands, otherwise braking performance will be reduced significantly.

21. Do not shower a new brake, this to prevent a small quantity of lubrication grease in the assembling clearance that can contaminate the braking pads.

22. Oil hydraulic disc brake has a strong braking force, you need to do much exercise at a safe place, so as to adapt to the difference from a common brake to avoid braking with too great a force, resulting in injury due to wheel lock up.

23. The use of the charger

24. Method of use

25. When charging, plug in the cell box first, then that of electric supply AC 220V, when charging is complete, take the counter procedures, that is , unplug the plug of electric supply AC220C, then that of cell box.

26. During normal charging , the indicator light of the charger shows red, when fully charged, it will show green.

27. When charging in ambient temperature that is too high, the red light will flash, which indicates that the charger is in the temperature protection state, please take the charger to a cool or well-ventilated place. When the inside temperature of the charger is lower than 60℃, normal charging occurs.

28. If there is no cell connected during usage and the chargers output has a pulse voltage less than 42V, when testing, place a 1 KΩ ohmic load between the positive and negative output terminal, then actual charging voltage of the charge can be obtained.

29. The matters needing attention

30. The charger can only be used indoor.

31. Charging in a closed space or under scorching sun or at a high temperature environment is strictly prohibited, do not put the charger on the seat or inside the rear compartment of the vehicle when charging.

32. Do not connect the charger to a AC power supply without charging for a long time.

33. During charging, if the indicator light is abnormal, there is abnormal smell or the house of the charger is to hot, please stop charging immediately, and repair or replace the charger.

34. Do not disassemble or replace the devices inside the charger by yourself.

35. Do not charge a battery that has been fully charged.

36. Do not use charger in an environment with flammable gas, otherwise fire explosion will be caused.

37. Do not place the charger near water source or wet it, otherwise fire or electric shock many occur.

38. In the event that inside parts are exposed due to charger damage caused by collision etc. Do not touch them with hands, otherwise you may be injured due to electric shock.

39. Use method and matters needing attention of the battery

40. Charging

41. Make sure to charge using the charger specifically equipped by our company, irregular or non-conforming chargers may reduce life of the cell or invalid the cell!

42. The cell that has been fully discharged (the vehicle stops running) can be charged with more than 95% of electricity within 5h, and can be fully charged within 8h.

43. During charging, neither the positive end nor the negative end is allowed to be in contact with metal.

44. When leaving factory, the cell’s electricity is about 80%, prior to driving the new vehicle, charge it for 3~10h.

45. If the vehicle is left for more than one month, cell’s electricity will reduce by about 5%. It is recommended to charge it before use.

46. Please charge the cell timely to ensure driving mileage.

47. During charging, the charger may become hot. As long as the temperature does not exceed 60℃, it is normal.

48.  When charging, please put the charger and the whole vehicle at a stable and dry place which is free of flammable and explosive goods and is out of reach from children.

49. You should charge the cell within 24h after it is fully discharged, and charging time should not be less than 3h.

50. Make sure that there is no short-circuit at the charging port.

51. The discharge (use)

52. Do not usea cell other than the one that is made for this model, otherwise warranty will not be provided.

53. Once short-circuit occurs, the cell management system will provide automatic protection, and the fuse piece connected in series with power lines will fuse, giving dual protection for you cell. At about 2 min after the short circuit is released and the fuse piece is replaced, the cell will work normally.

54. Damage or unreasonably configuration of the controller, motor, horn, lighting facility, etc. of electrical vehicle, all will cause the cell to discharge at high current. At this time, the cell will stop output for protection, but will recover within 10s, which will not have any effect on your driving.

55. Working temperature range of the cell: -10℃~55℃. Like other cells, its available energy will reduce with the rise of temperature, which is a normal phenomenon

56. Storage

57. If long-time storage (more than one month) is needed, it is recommended to charge the cell to 60%~80%of electricity. During storage, it is needed to charge the cell every 3 month, and charging is also needed before using.

58. The cell should be stored at a cool and dry environment.

59. During storage, prevent conductive objects to connect the positive pole with the negative one.

60. Do not use the cell near a fire source.

61. Do not disassemble the cell.

62. Do not refit the cell

63. Note

64. If the cell is found to deform or becomes hot, you should stop using and seek help from our company or repair department.

65. In case of fire, do not quench the fire directly using water. It is recommended to quench it using sand, foam, extinguisher or thick clothing soaked with water.

66. For the cell fault caused by delayed charging of fullydischarged cell, warranty will not be provided.

67. Do not discharge the cell haphazardly.
