Device Description: KuKirin G2 Max Scooter

The KuKirin G2 Max is an electric scooter designed for personal transportation, emphasizing user safety, ease of use, and practical maintenance. This manual outlines its functions, operational procedures, and care instructions to ensure a safe and enjoyable riding experience.

Function Description

The KuKirin G2 Max scooter is equipped with a comprehensive control system and various functional components to facilitate its operation. The main control system includes a handlebar with a left brake handle, a T-bar, an LCD display, a right brake handle, a headlight button, an electric lock, and a gear switch button.

The LCD display provides essential information to the rider, including turn left/right brake indicators, current speed, non-zero start status, single/double drive mode, battery level, battery capacity, and headlight status. It also shows the current gear, speed in km/h or mph, fault codes, and a cruise logo when activated.

The scooter features a telescopic head stem that allows for height adjustment, divided into three gears: low, middle, and high. This adjustment is achieved by loosening a quick release, pressing a ball bearing, and moving the T-bar up or down, then re-locking the quick release.

For safety, the scooter includes a braking system with both electric and disc brakes, controlled by the brake handles. A headlight and tail light system, along with side lights, ensures visibility during rides, activated by a dedicated light button.

The power system is managed by an electric lock, which requires a key to turn the power on or off. The scooter supports different riding modes, including a non-zero starting mode where the throttle system activates after the scooter reaches a certain speed (e.g., >3km/h). It also features a cruise control function that maintains a constant speed once activated, which can be disengaged by pulling the left brake handle or initiating electronic braking.

Usage Features

Operating the KuKirin G2 Max involves several steps, from assembly and expansion to riding and folding.

Assembly and Expansion: To prepare the scooter for use, first, pull the scooter open and extend the kickstand, securing the folding switch. Connect the main wire of the T-bar to the head stem and slide the stem onto the front fork, taking care not to pinch the wire. Use the provided toolkit to tighten the screws and verify power on/off functionality. To expand the scooter, press a clip with one hand while pulling the upright tube up with the other. Then, pull the T-bar up and secure the folding clip.

Folding: For storage or transport, the scooter can be folded. Ensure the power is off for safety. Pull the safety catch upwards, then push down the front of the E-scooter. Take the lever hook and insert it into the hook card slot to secure the folded position.

Riding Instructions: Before riding, choose an open area and wear protective equipment. Turn the key to the right to power on the scooter. Place one foot on the deck and the other on the ground. As the scooter starts to glide, place the second foot on the deck. Gradually press the throttle thumb shifter to accelerate. For emergency stops, hold both brake handles firmly. For normal stops, holding the left brake handle will power off and brake the scooter. The scooter supports a non-zero start function, meaning the throttle system will only engage after the scooter has started moving. The maximum speed limit is 25km/h, and headlights should be used when exceeding 15km/h.

Seat Assembly (Optional): The scooter supports an optional seat. To install, secure the seat bracket to the battery box pedal with four screws. Once secured, loosen the seat for quick disassembly. To attach the seat, insert it into the corresponding card slot. To remove it, turn it to unlock and quickly pull it out. For folding the seat, release it and recline it in the direction of the arrow, then press the seat axle on the side. When the seat axle is pressed to the bottom, place one hand on the seat bracket and slowly recline the seat. For expanding the seat, press down the seat axle while raising the seat bracket. Shake the seat bracket to ensure the seat axle is stuck in the slot.

Recharging: To recharge, open the waterproof plug of the charging port and insert the charger plug. Connect the charger to a power supply. The light on the charger will turn red during charging. After charging, cover the top cover.

Transfer: The scooter can be moved by hand, either with one or two hands, as shown in the manual's figures.

Maintenance Features

Proper maintenance ensures the longevity and safe operation of the KuKirin G2 Max scooter.

Lubricating Oil: Special grease should be applied every six months to the electric aircraft's moving parts. Regularly check for any faults and tighten bolts every three months.

Battery Care: Turn off the power when charging or not in use. If storing for an extended period, keep the electric scooter in a safe place and cover the battery. Charge the electric scooters at least once every three months to maintain battery health. Do not store the scooter in direct sunlight.

Battery and Recharger: The scooter is equipped with a lithium battery designed for at least 800 recharges and over 1000 normal uses. Charging should be done outdoors as lithium batteries can be dangerous during the process. The charging device has an automatic circuit breaker system that activates when the battery is fully charged. Charging typically takes 7-8 hours. If the battery is not charging or is damaged due to abnormal reasons, contact the service center. Damage caused by improper charging or using non-manufacturer charging devices may void the warranty.

Fault Code System: The scooter's LCD display can show fault codes to help diagnose issues:

E-001: Motor Hull Fault
E-002: Throttle Fault
E-003: Controller Fault
E-005: Battery Undervoltage Fault
E-006: Instrument Reception Fault
E-007: Instrument Transmission Fault

Troubleshooting (FAQ & Solution):

Black Display: Possible cause is prolonged direct sunlight exposure. Solution: Move the scooter to a dark place for a while.
Incorrect Display Readings: Possible cause is incorrect parameter settings. Solution: Reset options.
Opaque Display or No Display: Possible cause is poor contact connection or an uncharged battery. Solution: Restart the electric vehicle or contact the service center.
Complete Diagnosis: If issues persist, check power, display screen, brake functionality (right and left), and ensure all jacks and connection holes are properly connected. If the problem continues, contact the seller.
