• AB-1816 requires less pedal power than a normal bicycle to move. However, until the cyclist gets used to lighter pedaling, he or she may pedal too powerfully, causing faster speeds than a normal bicycle, which may lead to accidents, such as a fall or crash.
• Do not ride the bicycle across extremely bumpy surfaces (pavement curbstones, drainage runs, etc.).
• When bringing the bicycle to a halt, apply both front and rear brakes.
• Do not ride the bicycle when there is a problem with it.
• Do not dismantle or lubricate the parts comprising the power assist system.
• Do not remodel the bicycle by yourself.
• Only use genuine parts as accessories or replacements.
• After removing/replacing wheel(s) or adjusting the saddle, always check that relevant bolts have been tightened before riding the bicycle.
• Never ride the bicycle with the saddle or handlebar higher than the limit line.
• Do not lubricate brake, tires or rims in damping areas.
1. Check before use.
For the safety use, please check the following before using it. a. Check if the tires and screws work well. b. Brake system: When the brake level reaches its 1/2
range, the brakes have to stop the bicycle completely.
c. Power system: Check if the battery is fixed well, and
the power is full for use.
2. Attention:
a. Please decelerate when turning and going downhills.

3. Operation
3.1 How to adjust your position on the bicycle
1. Measure your height. (Fig. 1)
2. Refer to the bicycle’s settings table.
3. Adjust your bicycle. (Fig. 2 – 3)
Warning
• Do not ride the bicycle when the safety lines on the seat or handles are visible.
Adjusting the seat
Minimum seat height is the height determined when the position of the seat is lowered and the clamp is locked.
Practical Information
Depending on the terrain you are travelling on, the seat height can be modified:
- On a flat ground or when climbing, the seat should be in a high position for the greater efficiency.
- When travelling downhill, the seat should be slightly lowered to improve bicycle control and to make it easier to go over or circumvent obstacles.
3.2 Introduction of battery:
Use and care for AB-1816
• Remove the battery from AB-1816 when not in use.
• Recharge only with the charger specified by the manufacturer. A charger that is suitable for only one type of battery pack may create a risk of fire when used with another battery pack.
• Use AB-1816 only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• When the battery pack is not in use, keep it away from metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, which can make a conductive connection from one terminal to another. Shorting both the battery under abusive conditions, terminals may cause burns or a fire.
• As liquid may leak from the battery, avoid contact. If you touch it accidentally, flush with water. If the liquid contacts with eyes, seek medical help. Liquid leaked from the battery may cause irritation or burns.
IMPORTANT SAFETY INSTRUCTIONS
For battery cartridge
• Before using battery cartridge, read all instructions and cautionary markings on the (1) battery charger, (2) battery, and (3) product the battery is used for.
• Do not disassemble the battery cartridge.

• If operating time has become excessively shorter, stop operating immediately. It may result in a risk of overheating, possible burns and even an explosion.
• If the electrolyte gets into your eyes, rinse it out with clear water and seek medical attention right away. It may result in loss of your eyesight.
• Do not short the battery cartridge:
(1) Do not touch the terminals with any conductive
materials.
(2) Avoid storing battery cartridge in a container with
other metal objects such as nails, coins, etc.
(3) Do not expose the battery cartridge to water or
rain. A battery short can cause a large current flow, overheating, possible burns and even a brakedown.
• Do not store AB-1816 and battery cartridge in locations
where the temperature may reach or exceed 50°C (122°F).
• Do not incinerate the battery cartridge even if it is
severely damaged or is completely worn out. The battery cartridge can explode in a fire.
• Be careful not to drop or strike the battery.
• Do not use a dropped or struck battery.
SAVE THESE INSTRUCTIONS.
Tips for maintaining a maximum battery life
• Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
• Charge the battery cartridge with a room temperature
at 10°C – 40°C (50°F – 104°F). Let a hot battery cartridge cool down before charging it.
Instruction of installing or removing battery cartridge
Installing battery cartridge
Insert the key into the key hole and turn the key counter clockwise 90°. (Fig. 4) Open the cover and always insert the battery cartridge all the way until it locks in place with a little click. If you can see the red part on the upper side of the button, it is not locked completely. Insert it fully until the red part cannot be seen. (Fig. 5 & 7) Close the cover and insert the key to the key hole and turn the key to clockwise 90°. (Fig. 6)
NOTE:
Even with one battery cartridge, the assisting function works, but the total battery life will be half compared with that when using two battery cartridges.
Removing battery cartridge
Open the cover with the key. To remove the battery cartridge, withdraw it from the tool while sliding the button on the front of the cartridge.
(Fig. 7)
3.3 Instruction of display and button (Fig. 8) Operation
1. The ON/OFF button is the power switch. Press ON/ OFF button rightly to turn ON power source for bicycle.

• Ne transformez pas le vélo vous-même.
• Utilisez uniquement des accessoires et pièces de rechange Dolmar.
• Après avoir retiré/remplacé la/les roue(s) ou réglé la selle, vérifiez toujours que les boulons correspondants sont bien serrés avant d’utiliser le vélo.
• N’utilisez jamais le vélo lorsque la selle ou le fermoir sont plus hauts que le repère limite.
• Ne lubrifiez pas les tampons de frein, les pneus ou les jantes.
1. Vérifiez avant utilisation.
Pour une utilisation en toute sécurité, vérifiez les points suivants avant d’utiliser le vélo. a. Vérifiez le bon fonctionnement des pneus et des vis. b. Système de freinage : lorsque le niveau de freinage
atteint la moitié de sa capacité, les freins doivent être en mesure d’arrêter totalement le vélo.

1. Mesurez-vous. (Fig. 1)
2. Reportez-vous au tableau des réglages de votre
bicyclette.
3. Réglage de votre bicyclette. (Fig. 2 à 3)
Avertissement
• N’utilisez pas la bicyclette lorsque les repères de
sécurité sur la selle ou le guidon sont visibles.
Réglage de la selle
La hauteur minimale de la selle correspond à la hauteur définie lorsque la selle est abaissée et le collier verrouillé.
Informations pratiques
Selon le terrain sur lequel vous circulez, vous pouvez modifier la hauteur de la selle :
- Sur un sol plat ou en côte, vous pouvez régler la selle
en position haute pour une plus grande efficacité.
- En descente, la selle doit être légèrement abaissée
afin de permettre un meilleur contrôle de la bicyclette et faciliter le passage ou le contournement d’obstacles.
3.2 Présentation de la batterie : Utilisation et entretien du AB-1816
• Lorsque vous n’utilisez pas le AB-1816, retirez sa
batterie.
• N’utilisez que le chargeur spécifié par le fabricant. Un
chargeur qui convient à un seul type de batterie peut créer un risque d’incendie s’il est utilisé avec un autre type de batterie.
• Utilisez le AB-1816 uniquement avec les batteries
désignées. L’utilisation d’autres types de batterie peut créer un risque de blessures et d’incendie.
• Lorsque le bloc-batterie n’est pas utilisé, gardez-le
éloigné de tout objet métallique, comme les trombones, pièces, clefs, clous, vis ou autres petits objets métalliques, qui peuvent faire office de connexion
