Operation Manual for Jinjiang Shenggong Machinery Electric Tricycle

I. Product Usage and Operation Methods

1. Pre-Driving Inspection

1) Check tire pressure and condition

• Check if the tire pressure is normal and if there are cracks or cuts on the tires.① Excessive inflation (referring to pressure higher than 5 bar) will cause severe 颠簸 during driving, and may lead to tire blowouts or bulges in summer.② Insufficient inflation will reduce driving speed, increase power consumption, and shorten the driving range.③ Tires with cracks or cuts are prone to blowouts.

2) Check the flexibility and effectiveness of operating systems such as braking and steering; check if the power-off device can cut off power before braking. Brake adjustment methods:

① Loosen the M8 nut on the rear brake lever. With the handbrake released, pull the rear brake lever forward by hand. Then adjust the rear M8 nut until the front M8 nut of the lever joint is 5-8mm away from the joint. Release the hand and tighten the M8 nut.② If the adjustment thread of the rear brake lever is insufficient, adjust the M10 nut on the front brake lever to adjust the brake.

Attachment: Brake Inspection

1. Release the handbrake. When pushing the empty vehicle by hand, the tires should roll flexibly without obstruction.

2. Pull the handbrake; it should be able to lock the wheels. When pushing the vehicle with force, the wheels should not rotate.

3. When stepping on the brake pedal, both rear wheels should lock simultaneously (the brake pedal should be 3-5cm away from the platform).

4. If the above requirements are not met, adjust the brake to meet them, or contact after-sales service for maintenance assistance.

Note: When the brake pads are worn down to half their original thickness, replace them to ensure driving safety. If the brake fails, immediately turn off the forward/reverse combination switch to stop the vehicle, and then have it inspected and repaired at a relevant workshop before driving again.

3) After using the new vehicle for one week, conduct a systematic inspection and reinforce all fasteners as a whole. In particular, adjust the brake system twice as a whole to ensure safe driving.

4) Check if the battery power is sufficient and if the circuit and all electrical components work reliably. Insufficient charging not only affects the driving range but also shortens the battery life.

5) Check if the drive chain tension is appropriate. Chain adjustment methods:

① First, loosen the M10 fixing nut of the motor base. Then adjust the motor pull rod to tension the chain. After tensioning, first tighten the M12 nut on the motor pull rod, and then tighten the motor base fixing nut.② If the chain is misaligned, first loosen the M10 fixing nut of the motor base. Then adjust the motor to keep the chain in the same plane on the front and rear sprockets, and then tighten the motor nut.

2. Usage and Operation Methods

1) Vehicle Start-Up

Turn on the power switch, set the forward/reverse switch to the forward gear, turn on the turn signal, and set the speed switch to the low gear (the vehicle must start at a low speed). Step on the brake pedal, release the handbrake, confirm there are no obstacles ahead, and release the brake pedal. The vehicle will start moving at a low speed. (If using stepless speed change for start-up, twist the stepless speed change handle inward.)

2) Normal Vehicle Driving

Turn off the turn signal, gently step on the brake pedal to cut off the power of the power-off switch (observe the AV meter returning to "0"). Turn the speed switch to the high gear or stepless speed change gear, confirm there are no obstacles ahead, and release the brake pedal. The vehicle will start moving at high speed or the stepless speed change will start working. (Note: The selection of high gear depends on road conditions and traffic safety. When driving normally or with a heavy load, use high gear or stepless speed change gear as much as possible. Do not drive in low gear for a long time to avoid burning out resistors and other components.)

3) Vehicle Turning

Reduce the speed in advance, turn on the turn signal for the direction of the turn, and turn when it is safe (when it does not hinder the oncoming vehicles and the visibility is poor, drive as slowly as possible and increase the turning radius).

4) Vehicle Parking

Turn on the right turn signal, observe the rear situation through the rearview mirror, confirm safety, and pull the vehicle over to the parking position. Step on the brake pedal to stop the vehicle, then pull the handbrake lever to a secure position, turn off the key power switch, and set the forward/reverse switch and speed switch to the neutral position. If the driver needs to leave the vehicle, be sure to pull out the key and confirm the vehicle is safe before leaving.

5) Vehicle Reversing

Step on the brake pedal to stop the vehicle, set the driving switch to reverse gear and low gear or adjust the gear, release the brake pedal to start reversing, and a reverse voice prompt will sound simultaneously.
