Step1. Turning on the main switch
When turning on the product, you can start driving by turning on the main power switch first (when using the built-in battery) and turning on the power of the LCD panel. When driving is finished, turn off the LCD panel and turn off the main power.

The power of the instrument panel will turn off automatically after a few minutes of inactivity. At this time, the LED lamp is also turned off, so turn it off with the LED lamp utton when you turn it on again and turn off the main power switch after use.
Step2. Turning on the instrument panel
Press the POWER button on the instrument panel for 2 seconds to turn on the instrument panel. You can set the start mode, cruise mode, electronic brake, and ABS function.

Step3. Stance for driving
After tilting the kickstand, find a stable position on the footrest and then hold the handle grip comfortably. Be careful not to raise your foot on the rear fender.

Step4. Acceleration and deceleration
Acceleration can be performed by using the throttle of the instrument panel while driving, and the deceleration or stop can be performed by holding the brakes on the handle.

**Before driving, be sure to check the folding part, the handle part, the part where the main fixing part of the product is fastened well. And check the position of the fixing slide, the QR lever locking status, and the folding part fixing status.
Throttle malfunction caution**
Regardless of whether the throttle is operated or not, the motor sensor may continue to operate, causing malfunctions such as sudden acceleration. In this case, holding the brake lever cancels the operation. This phenomenon may be caused by corrosion of the throttling, immersion of the throttle, disconnection of the magnet, broken off levers, and breakage of the spring. Do not pull the throttle lever strongly.

3) How to stop

Tip
Check for safe braking

For safe braking, check whether the brake lever and disc caliper connection (wire damage, external breakage, etc.) are damaged before and after driving, and check brake wear and looseness of brake inner core(Inner wire). In the case of hydraulic brakes, it is also necessary to check the oil leakage or deficiency and always check that the braking force is sufficient.
Due to various factors such as road surface condition and speed, it may not be possible to stop when the brake is operated as expected. The electronic brake and ABS unctions are auxiliary functions to further increase the braking force and use. The user should understand the function and expect the operation timing when using this function.

4) Product folding

Fold handlebar and steering tube
After folding the handlebar, unscrew the QR lever outward and lay the steering tube down while raising the fixed slide.
Fixing the folding part
When the steering tube is folded, it is fixed by using the locking slide and QR lever, then it is easy to move by attaching the handle with the folding lock device (not available when mounting the seat mount).

Features of cruise mode (automatic driving)
The cruise control function allows you to maintain the driving speed automatically. Take advantage of cruise features.
The advantage of being able to reduce fatigue when traveling long distances and to increase the mileage of driving due to constant speed driving.
(1) The start of the cruise function
Select the Cruise function section of the dashboard as ‘Settings’ and set the throttle to the same Acceleration. The cruise function will start. (2) End of cruise function
When you hold and release the brake while cruise mode is in effect, the cruise mode is automatically released.
Precautions when using the cruise function

In case of cruise function, please ride in a position where the brake can be used immediately so that cruise function is canceled and braking is possible in preparation for safety situations while driving.
It is permanently dual drive mode and can be released via throttle and brakes.

It is not recommended that the cruise function be disabled via the throttle.

5 ) Setting of Electronic brake

How to use the instrument panel ****

*** Precautions when using electronic brake immediately after full battery charge**
The electronic brakes do not operate when the battery is fully charged, so be sure to check and operate this device. When the battery runs out, the electronic brake will operate normally.

6) ABS function setting guide
All-electric motorcycles are subject to sudden braking, causing the wheels to stop spinning. As a result, the slip of the tire causes the driver to fall down, which can cause accidents. his product is equipped with an ABS brake function to hold the tire lock, enabling more secure braking.

(1) ABS function ON
Set the ABS function part Pd of the dashboard to 1.
(2) ABS function OFF
Set the ABS function part Pd of the dashboard to 0.

Pd – When the ABS function is ON, the PA – electronic brake function is canceled.
ABS brake is an abbreviation of Anti-Lock Brake System. It uses the principle that maximum static friction force is larger than kinetic friction, so that braking distance from breaking to stopping) is shorter than that of the normal brake. It has the advantage that the vehicle does not slip well when the wheel is rotating. and it is a brake assist system that can stop more safely without wheel lock and slip.

* Precautions when using the ABS function
ABS has the advantage of being able to stop at the shortest braking distance that can be obtained from the tires and road conditions. However, due to the principle of repeatedly holding and releasing the brake several times in a second, a lot of vibration occurs in the motor and the body. Repetitive vibration caused by this may cause frequent loosening of the motor, rim, fixing part, and body fixing bolt.

Safety precautions for Lithium-ion battery

1) Proper Lithium battery management tips

Only use the charger that was supplied with your product to charge the lithium-ion batteries. The use of an unauthorized charger could cause serious damage to the battery and can cause a fire.
Charge lithium-ion battery within 0-45°C and discharge within -20-60°C. Charging and discharging the battery, not within the appropriate temperature may damage the lithium-ion battery.
Do not leave lithium-ion batteries in any place exposed to direct sunlight or high temperature. Do not store it in wet places. Always store it in dry places.
Charge lithium-ion battery in dry, open, and well-ventilated place. Do not charge the battery near inflammable goods.
In the winter, bring the battery from outside to inside, temperatures changed from low to high and this may cause dew condensation. In this case, do not charge the battery immediately, but charge it after reducing the temperature difference.
If the battery protection circuit is damaged, the battery emits an unusual smell, or the battery leaks, contact the authorized service center immediately and get technical support.
Put lithium-ion batteries in a safe place out of the reach of children and pets.
Do not reverse the polarity on a battery and short-circuit. Also exposing the battery to excessive shock can result in an explosion of the battery.
Do not do stunts or jumps on the product on bumpy surfaces. Exposing a battery pack to excessive shock can result in fire on the battery. If there are some crashes while driving, then you should remove it from the product to check whether the battery is working well.
Connecting the charger when the product is waterlogged, the risk of electric shock and fire is very high. Do not charge the battery in this case and the battery should be checked by an expert before charging.
Do not disassemble or incinerate the lithium-ion batteries. To safely dispose of the lithium-ion battery, put it as industrial waste and be careful not to short-circuit occurs in the terminals.
If the battery requires replacement after long-term use, replace it with the new one through the authorized dealer. Normally, the discharge capacity of lithium-ion batteries normally decreases more than 15% after 300 times of cycle use.

Safety guidelines before driving

Required checking before use

Check throttle and handle
• Operate the accelerator throttle lever about 2 ~ 3 times to check whether it returns to the home position.
• Be careful that excessive throttle leaning and manipulation of the throttle can cause malfunction due to internal parts damage.
• Check the fastening condition and clearance of the QR lever on the handle.
Check brake and cable
• The brake braking force is sufficient to check the operating condition. If the braking force is significantly lowered, use it immediately after inspection and action.
• Check that the brake pad is not worn, that the cable is not loose, that the cable is not damaged, or that there is no leakage in the case of hydraulic brakes.
• If there is an unusual feeling or noise during operation, check for breakage, wear, and deformation of the inner wire of the brake cable.
• Check that the bolts and nuts of the brake fixing parts are not loose and that the disc is not deformed or damaged.
Check tire pressure and uniaxial condition
• Check the front and rear tires for wear and punctures and check the proper air pressure (45 to 50 psi) for the tire. When the shortage of air is shortened, the possibility of
puncture increases, so check always.
• It is necessary to judge the replacement time by observing the appearance of the tire such as tire damage, uneven wear.
Tightening check such as folding part and handle part
• Make sure that the bolts and nuts of all parts of the product are tight and free from loosening. Check the fastening condition and clearance of the folding and fixing parts of the handle (QR lever, fixed slide, hinge center bolt, headset nut, swing arm, etc.).

If there is a folding clearance,
If there is a folding clearance, it can be adjusted with a tongue bolt. However, if you pull it too hard, it will become stiff without a gap, but it may sound ‘crackling’. In this case, if you adjust the tuning bolt properly, the noise disappears and the clearance is also adjusted.
* In this case, stop driving immediately.
If you encounter any of the following situations while driving, stop driving immediately and contact your nearest branch or service center for proper measures. If you provide pictures and videos to get an accurate diagnosis, professional counseling is available.
- Unusual heating of the motor
- Brake braking status error
- Error messages on the instrument cluster
- When the throttle is returned to its original position
- abnormal noise is generated
- Product smoke, ignition, sour odor
- When rain or wet with water or in a similar situation
- When other driving is judged to be unreasonable

Maintenance

2) Maintenance and self-maintenance

Electric products can be damaged by various factors. The life span of each part varies depending on driving habits and the driving environment. Parts that exceed the service life may cause accidents. Let’s manage various parts and prevent safety accidents in advance.

Check the replacement timing of consumable parts
※ The rubber inside the rubber suspension is cured as the consumable parts are used, and the performance of the suspension is slightly reduced because of the reduced elasticity.
① The components and suspension parts of the car swing arm, tires, tubes, wheels, bearings, headset bearings, discs, brake pads, cables and folding parts, various brackets, and other consumable parts requiring periodic inspection and always check.

DUALTRON VICTOR

2. External damage inspection by driving environment

① Replace parts that may be damaged by the external driving environment, such as deformation of parts, cracks due to compression, and signs of exceeding fine gold or life expectancy.
② If the product is exposed to strong sunlight for a long time, discoloration may occur.
③ In case of heavy driving such as normal jumps, slight impacts such as turning, collision, etc., when driving frequently or for a long time in a poor road condition or driving for thousands of kilometers or more, fatigue breakdown phenomena Please check and replace the parts replacement schedule for each product for safety. ④ Fatigue breakdown and maintenance parts may differ from the example conditions depending on the driving environment and the operating conditions. Also, check parts other than the replacement cycle (maintenance parts) at all times to check for any signs of abnormality.

Important notice

Important notice

Metal vibration may occur due to motor vibration, the vibration of the brake disc and pad during the load section that accelerates during driving. (About 15 ~ 30Km, different for each product)
This is a phenomenon in which all revolutions (fans, automobiles, ships, etc.) are vibrating at a specific rotational frequency (rpm) rather than the product. However, if the continuous noise or metal noise is large, there is a possibility that the disk is bent and deformed.
Please note that after running, there is a risk of burns due to the heat on the motor and brake (especially disk rotor) side.
Be careful that the bolts of the motor, rim and motor shaft due to the ABS function may be loosened.

3) Maintenance by self-maintenance

Brake adjustment method
If the braking force decreases due to overheating of the oil, damage of the oil hose, loosening of the brake lever, oil leakage, etc. after using the brake for a long time on
the downhill road, stop using and use after checking it.
Causes and countermeasures of disc brake noise The disc braking method use a disc brake method with many electric kickboards because braking power is good. however, if you get a sharp hissing sound when you hold the disc brake, dust or sand particles on the ground will spill out on the surface of the disc, causing foreign substances to be on the brake pads or disc surface, or bending due to heat or external impact. If that happens, clean the inner surface of the disc by turning the wheels with a clean, dry cloth, or straightening the bent discs.

**** If the above measures are not taken, please visit the nearest branch and take a safety check. There may be another problem.

4. Variable rubber suspension system (patent pending) adjustment
