Batteries

Observe the correct polarity when inserting batteries.
Do not expose batteries to high temperatures and do not place them in locations where the temperature might increase quickly, e.g., near fire or in direct sunshine.
Do not expose batteries to excessive radiant heat, do not throw them into fire, do not disassemble them, and do not try to recharge non-rechargeable batteries; they could leak or explode.
Disposal of a battery into fire or mechanically crushing or cutting a battery can result in an explosion.
Leaving a battery in an extremely high temperature surrounding environment can result in an explosion or the leakage of flammable liquid or gas.

Using Your E-Scooter

Riding

Before riding, ensure that it is safe to do so and the e-scooter is operated in accordance with this User Manual. It is important that safety equipment is worn and the scooter is in good condition.
If using your e-scooter for the first time, practice how to use it away from public spaces and wear safety equipment. When you are confident to use your e-scooter, you can operate near other people and vehicles.
When riding, always follow your country's legal requirements.
Check that the brakes, lights, and tires are working, correctly adjusted, and in good condition before riding.
To ride your e-scooter safely:
To turn on your e-scooter, press the [power button] (M) button for 3 seconds.
Make sure you are wearing suitable safety equipment.
Power on the e-scooter.
Place one foot on the footrest first, and the other foot on the ground. Kick the scooter to move forward, and slowly press down the accelerating throttle.
To turn off your e-scooter, press the [power button] (M) button for 3 seconds.
NOTE: When accelerating, lean backwards to maintain your center of gravity. When decelerating, move your center of gravity by leaning forward. This will make your riding more comfortable and safer.

Braking

Core S3 (KS3CD): To brake correctly, release the accelerating throttle and engage the disc brake using the brake lever on the right-hand side of the handlebars, which operates the rear disc brake. At the same time, gently apply pressure with your foot to the fender brake. In addition to the disc and fender brakes, the electronic brake will cause the motor to slow down.
Core S4 (KS4CD): To brake correctly, release the accelerating throttle and engage the disc and drum brakes using the brake levers on the handlebars. The left-hand brake lever operates the front drum brake, and the brake lever on the right-hand side operates the rear disc brake. In addition to the disc and drum brakes, the electronic brake will cause the motor to slow down.
It is recommended that the rear disc brake is engaged slightly before the front drum brake to ensure smoother braking.

Indicators

To operate the indicators, use the Indicator Switch located on the left-hand side of the handlebars. This switch has three positions: left turn signal, off, right turn signal.
When the switch is pressed to show other road users that you intend to move left or right, the respective light will flash at the end of the handlebar.
To cancel the indicators, return the switch to the central position.
The indicators will only work when the e-scooter is turned on.
The indicators will not self-cancel; remember to cancel the indicator when the movement has been made.

Walk Mode

While in Walk Mode, the brake light will flash to indicate that your scooter is traveling slowly. When changing to Medium Mode, the brake light will stop flashing.
While in Walk Mode, the walk mode indicator will appear on the display.

Kick Stand

Your e-scooter has a built-in stand that allows it to be parked without the need to lean it up against anything or having to collapse it for storage.
To use the Kick Stand, use your foot to press it downwards until it locks into place. Lean the e-scooter so that it rests on the ground. Do not use the Kick Stand on uneven or soft surfaces.
To release the Kick Stand, use your foot to push it upwards and into the body of the scooter; it will lock into place. Ensure that the Kick Stand is stowed correctly before riding.
Be careful when deploying the kick stand, as it may cause injury if used incorrectly.

Charging

Ensure that the battery fitted to your e-scooter is charged correctly by following the instructions below:
1. Plug the charger lead into the e-scooter charge port. Refer to the diagram of the charging port on your e-scooter.
2. Plug the charger mains lead into the mains wall socket.
When connected to the battery charger, the battery will start to charge, and the charge indicator will turn red. After charging is complete, the charge indicator will turn green.
3. Disconnect the battery charger when fully charged and replace the rubber cap on the e-scooter charge socket.
NOTES:
If the scooter is not being used regularly, it is recommended to charge the battery every month.
Do not charge the battery outside.
Do not charge if the cable or scooter is wet.
Do not charge when the scooter is powered on.
Do not charge the battery if the ambient temperature is below 1°C.

USB Charging Socket

For your convenience, a USB charging socket is located on the display module. To access the socket, pull the socket cover to one side.
The USB charging socket is designed to keep your mobile device charged while being used with your e-scooter.

Assembling the Handlebars

With reference to the diagrams, assemble the handlebars with the supplied Allen key. This only needs to be done when the product is unboxed; the handlebars do not have to be removed after being attached.
Insert the handlebars into the handlebar stem as shown in the diagrams. The handlebars must be oriented as shown. While assembling, be careful not to bend or break any parts.
Ensure that the screws are not overtightened and that the handlebars are secure and do not wobble after construction.
Ensure that the brake cable is not bent or damaged.

Unfolding and Folding the E-Scooter

How to unfold? Refer to the diagrams to unfold the e-scooter. Press down on the rear fender with one hand and use the other to lift the Handlebar Stem so that it is straight. When straight, it will not move further. Once locked, use the Fold Lock Lever to secure it in place. This lever must be as close to the Handlebar Stem as possible when in the lock position.
How to fold? Refer to the diagrams to fold the e-scooter for storage. Lift up the Fold Lock Lever to release the Handlebar Stem. Push the Handlebar Stem down until it is touching the Rear Fender. Press it down so that it connects with the hook in the Rear Fender.
Note: On the Core S4 (KS4CD), the Fold Lock Catch is located on one side of the display, resulting in the handlebar stem being slightly diagonal to the Foot Pad when correctly located.

Care and Maintenance

When not using the e-scooter, store it in a dry environment to avoid damage to electronic components due to moisture.
Do not store the e-scooter outside for an extended period of time, as excessive exposure to sunlight, high temperature, or low temperature may damage the e-scooter and accelerate wear of tires and batteries.
Do not touch the disc brake disc immediately after using the disc brake, as there is a danger of high temperature burns!
Disc brake adjustment: If the brake is too tight, use the provided hex wrench to slightly loosen the screw holding the brake cable on the disc brake to release tension. Then slightly extend the position of the brake cable bolt. If the brake is too loose, perform the opposite operation and adjust the brake cable.
If any damage is found on your e-scooter, do not store indoors due to potential fire risk.
Should you experience any issues with care and maintenance, contact your dealer or SHARP Support.
