1. Safety Precautions for Riding

Please follow traffic regulations to ensure safe riding. Control your speed within a safe range (note that a safe speed should not exceed 30 km/h).

Before starting to ride, read the user manual and then find a safe place to practice. Make sure you fully understand the riding technique and familiarize yourself with the design and technical specifications — this is the basis of safe riding.

Do not allow anyone to ride the electric scooter unless they have received full instruction and studied this manual.

Prohibited:

• Riding with one hand
• Riding without holding the handlebar
• Riding while intoxicated

Pay special attention during rainy and snowy weather. Rain and snow may cause slipping while braking on wet surfaces.

Therefore:

• Do not ride at high speed in such conditions
• Turn carefully

Remember: start braking earlier on wet surfaces to avoid accidents.

The electric scooter must only be used while wearing a helmet.

Proper helmet use:
Put the helmet on your head and fasten the strap before starting to ride.

Proper clothing:
Do not wear tight clothing while riding. Make sure your body can move freely.

Recommended:

• Clothing with closed cuffs
• Shoes with low heels

Do not overload the scooter. The recommended maximum load is 100–120 kg depending on the model.

If the load is too high, the handlebar may vibrate strongly, which is dangerous.

Normal load: up to 120 kg.

2. Operating Methods

Riding

Maintain a relaxed posture and proper body position.

When riding while standing, increase speed smoothly to prevent shifting the center of gravity due to sudden acceleration.

Reduce speed on rough roads or gravel surfaces.

In rainy or snowy weather the road surface becomes wet, which may cause slipping during braking. Pay special attention to this.

It is recommended to avoid riding if the surface has many deep puddles. Water may enter the battery compartment and cause a short circuit or fire.

Moisture may cause incorrect battery operation. Damage caused by moisture is not covered by warranty.

Parking

When parking, pay attention to vehicles and pedestrians around you.

Slowly park the scooter on a flat surface. After secure parking, turn off the power using the control unit button.

Battery Charge Indicator

Turn on the control unit button and the charge indicator will appear.

When the battery is fully charged, all bars of the indicator will be lit.

Recommendation: connect the charger when only one indicator bar remains, and do not allow the battery to fully discharge.

Throttle Lever (Speed Control)

The scooter accelerates when the throttle trigger is pressed toward the rider.

When the throttle is released, braking begins.

After power is cut off, the motor stops.

3. Disc Brake Operation Rules and Precautions

Gap Adjustment

Turn the adjustment screw (located between the brake lever and the handlebar frame) using a 2 mm hex key.

Adjust the gap between the brake pad and the disc until comfortable braking is achieved.

Brake Pad Replacement

After 6 months of use, or if wear exceeds 1 mm (or the screw can no longer adjust), the brake pads must be replaced.

When replacing:

1. Press one pad using a Phillips screwdriver to create space.
2. Install the new pad.
3. After replacement, adjust the screw so the lever is in a comfortable position.

Warnings

• Do not lubricate brake pads or calipers with engine oil.
• Do not touch the brake disc or pads with your hands. This significantly reduces braking efficiency.
• Prevent moisture from getting onto new brake pads.
• Avoid sudden wheel locking, which may cause injury due to uncontrolled skidding.

4. Charger and Battery Safety Precautions

Operation

During charging:

1. First connect the plug to the battery unit.
2. Then connect it to the 220 V power outlet.

After charging:

1. First unplug the charger from the 220 V outlet.
2. Then disconnect the connector from the battery.

During normal charging the indicator glows red.
When charging is complete it turns green.

If the temperature is too high, the indicator flashes red (overheat protection mode).

Move the device to a cool ventilated place. Charging will resume once the temperature drops to 60 °C.

Charger Warnings

• Use indoors only.
• Do not use in isolated spaces with high temperatures.
• Do not connect the charger without load for long periods.
• If the indicator flashes, there is an unpleasant smell, or overheating occurs — stop charging immediately and take the device to a service center.
• Do not replace the charger without approval from a service center.
• Do not charge batteries that are not rechargeable.
• Do not use near water or in humid rooms (risk of short circuit and fire).
• Do not use in explosive gas environments.
• If the battery case is damaged in an accident, do not touch it (risk of electric shock).

Charging

Use only the recommended charger.

After full discharge:

• 95% charge: 4–5 hours
• Full charge: 5–6 hours

During storage for one month the battery may lose about 35% of its charge. Recharge before use.

Charge the battery in time to ensure maximum range.

During charging do not allow the positive and negative terminals to contact metal parts.

When delivered, the battery charge is 35–80%.
A new scooter must be charged 3–4 hours before first use.

The charger surface may heat up (normal temperature up to 60 °C).

Store the charger and scooter in a dry place away from explosive materials. Keep children away during charging.

After full discharge the battery must be charged within 24 hours (minimum 3 hours).

Battery Discharge

Improper use voids the warranty.

In case of a short circuit, the system automatically switches to protection mode and the fuse is triggered.

After replacing the fuse, the battery will be ready for operation after 2 minutes.

If current consumption is exceeded (horn, lighting, etc.), the battery may temporarily disconnect but power will be restored after 10 seconds.

Operating temperature: −10 °C to +55 °C.
At extreme temperatures energy capacity decreases (this is normal).

The charging connector must not be short-circuited.

Storage

If stored longer than 1 month, recharge the battery to 60–80% every two months.

Store in a cool dry place.

Do not connect positive and negative terminals together.

Do not use near open flames.

Do not disassemble or modify the battery.

Warning

If the battery housing is deformed or overheated, do not use it. Contact a service center.

If the battery catches fire, do not pour water. Use a powder or foam fire extinguisher only.

Warranty does not cover batteries that were not charged on time.

A battery cannot stop functioning “randomly”.

5. Main Components of the Electric Scooter. Inspection and Maintenance

Inspection, Cleaning and Maintenance

• Check that all parts are present (as after the previous use).
• Check the brakes — they must function properly.
• Check the tires for punctures or cuts.
• Minimum pressure: 2/3 of volume, normal pressure 2.0 atm.
• Check the battery indicator (should show full charge).
• Check all bolts before riding and tighten if necessary.
• Do not wash under a shower or pressure washer. Wipe with a damp cloth or sponge.
• Every 6 months lubricate folding mechanism guides and shock absorbers with silicone lubricant.
