ROUTINE MAINTENANCE

Electrical Component Maintenance Instructions
Lithium-ion batteries should be stored in a cool, dry, and ventilated environment, away from sources of fire and heat. The optimal storage temperature for batteries is 10-25°C, with the best humidity being 60±25%. Batteries should be stored at room temperature and charged to 20% to 40% of their capacity.

To prevent battery over-discharge, it is recommended to charge and discharge the battery once every 3 months according to the standard charging and discharging method, and then charge it to 20%~40% of its capacity according to the standard charging method.

Brake Maintenance Instructions
Mechanical Brake Maintenance Instructions
For vehicles with short usage time, Just fine-tune the adjusting nut on the brake to adjust the braking effect to the appropriate state;
For vehicles with longer usage time, check the wear condition of the brake pads. If the brake pads are slightly worn, use an M5 Allen wrench to loosen the disc brake cable fixing nut, shorten the disc brake travel, tighten the fixing nut with the M5 Allen wrench, and then adjust the braking effect to an appropriate state;
For vehicles with longer usage time and severe wear of the brake pads, it is necessary to replace the brake pads to continue riding. To replace the front and rear disc brake pads, first remove the caliper fixing screw, use pliers to remove the clip, remove the pin, directly remove the two brake pads along with the spring, take out the two brake pads and the spring clip, then start installing new brake pads, attach the same model brake pads to the spring, pinch the two brake pads together into the caliper, and follow the steps in reverse order to reinstall.

Hydraulic Brake Maintenance Instructions
When maintaining the brake, use a special tool to unscrew the disc brake lever oil filling port screw, and then inject oil into the oil pipe with a syringe to adjust the braking effect to an appropriate state;
If the braking performance is still not ideal after oil injection, it is necessary to replace the disc brake pads to continue riding. Use an M5 Allen wrench to disassemble the front and rear disc brakes, remove the brake pads, then install the same model brake pads into the disc brake, reinstall the front and rear disc brakes with an M5 Allen wrench, adjust the disc brake to avoid friction with the disc brake rotor, and then normal riding is possible.
NOTE: Professional personnel should perform these operations.

Transmission Maintenance Instructions
When maintaining the transmission, the chain should be cleaned promptly after riding the whole vehicle and lubricated regularly with chain oil.

Suspension System Maintenance Instructions
When maintaining the suspension system, pay attention to whether there is mud and water inside the rear shock absorber and on the travel tube of the front fork, as mud and water can cause the rear and front shock absorbers to stick during use.
Clean and maintain regularly according to personal usage frequency to avoid a decrease in riding comfort.
NOTE: Professional personnel should perform these operations.

Tire Maintenance Instructions
Measure whether the tire pressure meets the tire label pressure; if not, adjust the pressure by inflating or deflating. After supplementing the pressure, ensure to put on the valve cap.
Depending on the frequency of use, if the tire tread is severely worn, the tire needs to be replaced to continue riding.

Whole Vehicle Appearance Maintenance Instructions
After using the vehicle, first use a duster to remove surface dust, then wash with a water gun at low pressure, but was top to bottom and avoid important electrical parts such as the battery compartment, motor shaft, and controller, then dry the whole vehicle with a dry cloth and store in a dry, ventilated place.

Do not use pressure wash systems as this may damage both mechanical and electrical parts of the vehicle. Damage caused by the use of pressure washing systems will not be accepted under warranty.

Common Fault Troubleshooting Instructions

Throttle Troubleshooting
If the battery is normal and the display screen lights up, then there is no fault with the display; if the display does not light up, there may be a fault with the display or controller.

Motor Troubleshooting
If there is not fault with the battery, display, or controller, and the motor operates normally when the throttle is turned, then motor is normal; if the motor does not turn, then is a fault with the motor.

Controller Troubleshooting
If there is not fault with the battery and the display, and the motor operates normally when the throttle is turned, then controller is normal; if the motor does not turn there may be a fault with the motor or controller.
NOTE: If any of the above faults occur, please contact the dealer for repair promptly.

Cleaning the vehicle
Regular and proper cleaning of your vehicle will extend its life of service
Preparation

• Wait until the motor cools down.
• Close all covers and electrical connections to prevent from water.

Do not use gasoline, rust remover, brake disc cleaner, etc. to clean plastic parts and painted parts, as this will cause them to deteriorate and be damaged.
Clean the vehicle as soon as possible after it has been driven in an environment containing salt.

It is best to clean the vehicle only with water and mild detergents or special cleaners provided by the professional dealers. Acidic cleaners are prohibited from cleaning the vehicle. If such acidic cleaner are used accidentally, please clean the area immediately to avoid damage to the vehicle. Then, use a dry towel or sponge to dry the vehicle.
Please always follow the care and cleaning instructions provided by the manufacturer.

Do not use high-pressure water guns or steam cleaners to clean the vehicle. This may cause water to enter bearings or electrical components, such as connections, switches or lighting, and may cause damage to brake pads, seals, paint or other parts.

Salt is of extreme corrosion
Therefore, these cleaning instructions shall be abided by: wait for the motor to be cooled, as well as use water and a mild detergent. Clean all metals and then treat parts with rust inhibiting spray, including inscriptions and nickel plated parts
Clean the dirt with warm water, a mild detergent and a soft, clean sponge. Then rinse thoroughly with clean water. Use a small brush to clean hard-to-reach areas.

After cleaning
In order to avoid rusting, we recommend the use of a suitable care product.

Make sure that no cleaning agents and lubricants are left on the brake discs, which may cause the brake system to fail while the vehicle is in motion and cause safety accidents. If the brake system is contaminated with such substances, please remove them before use.

Store the vehicle for a long time (two weeks and more)
Clean the vehicle.

• Charge the battery to 20%~40% of its capacity according to the standard charging method and check the condition every 3 months at the latest. Follow the instructions in chapter "Routine maintenance".
• Check or adjust the tire pressure and lift the vehicle off the ground so that all wheels are not in contact with the ground. If this is not possible, rotate the tires every month to avoid damage caused by partial stress on the tires over time.

Always keep the battery charged. Storing a depleted battery will cause permanent damage to the battery

If you are not familiar with the battery, please contact a specialist dealer.

To avoid over-discharge of the battery, it is recommended to charge and discharge the battery once every 3 months according to the standard charging and discharging method, and then charge the battery to 20%~40% of its capacity according to the standard charging method.

Store the vehicle in a well-ventilated area. High humidity air can cause rust and corrosion.

Short-term storage of the vehicle (within two weeks)
Store the vehicle in a cool, dry place, protected by a tarpaulin if necessary.
