Aairsk S600 E-Bike User Manual

1. Important Safety Information

Thank you for choosing Aairsk. Please read this manual carefully before using your Aairsk e-bike. If you have any questions, please contact us.

General Safety Guidelines

• We recommend your e-bike only be used by a person aged 16 years or older. Always supervise children until they are competent riders.
• Always observe local traffic regulations.
• Do not lend your e-bike to anyone unfamiliar with its operation.
• Stay within safe limits; if you feel you are traveling too quickly, you likely are.
• Always test your brakes prior to using the e-bike. Remember that the e-bike will not stop as quickly in wet conditions as it would in dry conditions.
• Be careful when using the front brake, especially when turning or on slippery surfaces, as locking the front wheel can be dangerous and may result in falling.
• Avoid consuming alcohol before riding your e-bike.
• Wear appropriate protective equipment and fully comply with applicable laws and regulations.

Battery Safety and Maintenance

WARNING: Please mind potential fire risk and strictly follow the instruction manual for charging and storage.

• You must connect the charger to the battery first and then plug the charger into the wall socket. Failure to do so may cause damage to the charger.
• The optimal usage temperature for the battery is 10°C/50°F - 45°C/113°F.
• In low temperatures, the available capacity of the lithium battery will experience varying degrees of attenuation. For example, at -10°C/14°F, capacity is approximately 60%; at 0°C/32°F, it is 85%; at 25°C/77°F, it is about 100%.
• The battery's capacity may drop to 80% to 95% of its original capacity by the second year.
• To ensure safety during transportation, the battery power from the factory is approximately 50-85%. Due to power consumption during transportation and storage, the battery power may be low or depleted during the first use. This is normal.
• Avoid exposing the battery and controller directly to rainwater or high-pressure water jets to prevent water ingress and potential short circuits.
• If the battery is submerged, remove it and dry thoroughly for 48+ hours in a ventilated area.
• If the controller is flooded, wipe battery contacts with a dry cloth, clean mud from wiring harnesses and controller gaps, and seek professional inspection for water-damaged components.
• NEVER attempt to charge or power on a wet system, as this may trigger hazardous short circuits.
• The battery is not a component that can be repaired by users. If any abnormal phenomena occur, please contact the after-sales department for maintenance. Unauthorized dismantling of the battery will void the warranty and may result in battery heating, smoking, fire, or explosion.
• Never use a charger other than the one provided with your Aairsk e-bike. Always charge the battery in a well-ventilated area, away from flammable materials.
• If the battery is left unused in the e-bike, it will slowly consume power. The e-bike can be kept unused for up to two months. After a long period of no use, the display may show lower battery power, which is normal.
• For long-term storage (more than one month), remove the battery from the e-bike and charge it to a half-full to full state (after discharging, charge for 1.5-2 hours). Store it in a cool and dry room (ideal temperature: 5°C/41°F-25°C/77°F) and charge it to about 80% every two months.
• Batteries and chargers should be stored in a clean, dry, ventilated place, away from corrosive substances, fire, and heat sources (at least 2 meters away). Disconnect the charger from the battery when not in use.
• The most suitable storage capacity for the battery is 50%. Storing the battery below 10% or above 90% for long periods will lead to irreversible capacity degradation.
• Avoid placing the battery in a risky location where a drop could cause uncontrollable damage, leading to leakage, heat, smoke, fire, or explosion.
• If you need to replace your battery, please dispose of it properly.
