User Manual for Electric Vehicles

Congratulations on purchasing a Koyten electric vehicle! To ensure your vehicle continues to operate safely and efficiently, regular maintenance is essential. This user manual provides guidelines on how to maintain your vehicle, including checking tire pressure, inspecting brakes, and ensuring the battery is in optimal condition. Follow the complete maintenance schedule outlined below to keep your vehicle in top condition.

1. Tire Maintenance

1.1 Checking Tire Pressure

• Importance: Proper tire pressure is crucial for safety, fuel efficiency, and tire longevity. Under-inflated tires can lead to poor handling and reduced battery efficiency, while over-inflated tires may cause a rough ride and uneven tire wear.
• Procedure:
  1. Locate the Valve Stem: Remove the valve cap from the tire’s valve stem.
  2. Use a Tire Pressure Gauge: Attach the gauge to the valve stem and read the pressure.
  3. Compare to Recommended PSI: Refer to the vehicle’s manual or the sticker located on the vehicle for the recommended PSI (pounds per square inch).
  4. Adjust as Necessary: If the pressure is too low, add air until it reaches the recommended PSI. If it’s too high, release air by pressing the valve until the correct pressure is reached.
• Frequency: Check tire pressure once a month and before long trips.

1.2 Inspecting Tire Tread

• Importance: Worn-out tire treads can reduce traction, especially in wet conditions, and increase the risk of accidents.
• Procedure:
  1. Visual Inspection: Look for uneven wear, cuts, or punctures.
  2. Tread Depth: Use a tread depth gauge to measure the tread. Replace the tire if the tread depth is below 1.6 mm (2/32 inches).
• Frequency: Inspect the tire tread every three months or before long trips.

2. Brake Maintenance

2.1 Inspecting Brake Pads and Discs/Drums

• Importance: Properly functioning brakes are essential for your safety. Worn brake pads or damaged discs/drums can lead to reduced braking performance.
• Procedure:
  1. Visual Inspection: Check the brake pads for wear. If they appear thin (less than 3 mm), they should be replaced.
  2. Check for Noises: Listen for any unusual noises (squeaking or grinding) when applying the brakes, which could indicate worn pads or other issues.
  3. Inspect Discs/Drums: Ensure there are no grooves or damage on the brake discs/drums. Replace if necessary.
• Frequency: Inspect the brakes every three months or 1,000 km (whichever comes first).

2.2 Checking Brake Fluid (if applicable)

• Importance: Brake fluid is essential for the hydraulic operation of brakes. Low brake fluid levels can cause reduced braking power.
• Procedure:
  1. Locate the Reservoir: Check the brake fluid reservoir under the seat or near the handlebars.
  2. Check Fluid Level: Ensure the fluid level is between the ‘MIN’ and ‘MAX’ marks.
  3. Top-Up if Necessary: If the fluid level is low, top it up with the recommended brake fluid type. Avoid spilling fluid on the vehicle’s body, as it can damage the paint.
• Frequency: Check the brake fluid level every six months.

3. Battery Maintenance

3.1 Inspecting the Battery

• Importance: The battery is the heart of your electric vehicle. Regular inspection helps ensure it is in good working condition, which is vital for vehicle performance and longevity.
• Procedure:
  1. Visual Inspection: Check the battery casing for any signs of damage, leaks, or corrosion.
  2. Check the Terminals: Ensure the battery terminals are clean, tight, and free of corrosion.
  3. Monitor Battery Health: Use a multimeter or a vehicle diagnostic tool to check the battery’s voltage and overall health. The voltage should be consistent with the manufacturer’s specifications.
• Frequency: Inspect the battery monthly.

3.2 Charging the Battery

• Importance: Proper charging practices extend the life of the battery and ensure it operates efficiently.
• Procedure:
  1. Use the Correct Charger: Always use the charger provided by Koyten or one approved for your specific model.
  2. Avoid Overcharging: Once the battery reaches 100%, unplug the charger to prevent overcharging, which can reduce battery life.
  3. Cool Down Before Charging: If the battery is hot after use, allow it to cool down before starting the charging process.
• Frequency: Charge the battery according to your usage. Avoid letting the battery discharge completely before recharging.

3.3 Battery Storage (if applicable)

• Importance: Proper storage practices prevent battery degradation during periods of inactivity.
• Procedure:
  1. Partial Charge: Store the battery at around 50-60% charge level.
  2. Cool, Dry Place: Store the battery in a cool, dry place away from direct sunlight or extreme temperatures.
• Frequency: Follow these guidelines whenever the vehicle will be stored for an extended period (more than two weeks).

5. Additional Tips

• Regular Servicing: Follow the manufacturer’s recommended service intervals. Regular professional servicing can identify and fix potential issues before they become serious problems.
• Keep Your Vehicle Clean: Regular cleaning not only keeps your vehicle looking good but also helps prevent dirt and debris from damaging key components.
• Software Updates: If your vehicle has an onboard computer or app connectivity, ensure that all software updates are installed promptly.
