Safety Notice
Using a safety helmet and protective goggles is strongly advised.
You are advised to take proper training or exercise before using on open roads.
Please follow the Operation Guide to fully understand how to properly operate the scooter.
It should be noted that the braking distance in bad weather will be much longer.
Please avoid braking on paint markers, manhole covers and oil stains to prevent slipping.
Pay extra attention when riding through railway crossings, junctions, tunnels, and bridges.
Slow down if road conditions are unclear.
Do not use high beam indiscriminately. Continuous use of high beam may disturb the vision
of the drivers and pedestrians.
Do not use mobile phones or other electronic devices which may draw your attention while riding.
Do not change the lane without signaling. Changing the lane at will is one of the major causes for accidents.
When you need to change the lane, remember to switch on the Turn Signal Indicator first. Always
check the vehicles approaching from behind before changing the lane.

Operation Guide Battery&Charger Use and Maintenance
1. When the scooter is completely stopped, the turning light switch turns off and the key is turned to the OFF position.
2. When parking, people stand on the left side and flat ground to step on the pedal lever of the main support,
step down with force and lift up with right hand. When you leave the scooter, in order to prevent the scooter be stolen,
please be sure to lock the anti-theft lock and take away the key.
Instructions for use of battery and charger
1. Charging and maintenance of batteries
This scooter uses maintenance-free lithium battery, the operating environment temperature is 0℃~+45℃,
too low will reduce its effective capacity, too high will affect its service life.Therefore, in winter or cold areas,
it is normal when the continuous distance after one charge is reduced. When the temperature rises above 20℃,
its function will resume naturally. The battery is an important component to protect the good performance of the scooter.
Please pay attention to proper protection. Please do not use the electric energy to the minimum allowable voltage every
time you ride. When the undervoltage indicator flashes, you must charge the battery.It is best to form the habit of charging
after riding every day, which is of great benefit to the battery life.
1. Turn the power switch to the ON position, whether all kinds of lights are on, whether all switches are working,
whether the horn is ringing, and whether the gate switch is normal.
2. If there is no difference, lay down the main bracket to make the rear wheel touches the ground.
3. After seated correctly, turn on the power lock and press the p switch. when the display interface of the
instrument jumps from the " p" screen to the " GO" screen, the p is unlocked and the whole vehicle can ride at this time.
When braking, It is recommended to brake the rear wheel before the front wheel, The effect is the best.
1. After returning the throttle quickly, hold the brake handle tightly.
2. The best way is to brake slowly and then tighten it.
3. Do not brake sharply or turn sharply. Emergency braking and sharp steering are the main factors causing sideslip
or rollover, which are extremely dangerous.

Battery Use and Maintenance
Attention
The new scooter battery maybe low due to delivery, transportation, etc. Please be sure to fully charge the
battery (the recommended charging time for the first time is 5 hours) before ridding.
If you do not use the electric scooter for a long time, please charging the battery regularly once a month,
otherwise the battery life will be seriously shortened
Don't throw away the waste batteries to avoid polluting the environment.
The waste batteries shall be recycled by the distributor.
2. Use and maintenance of charger
● Carefully check whether the rated input voltage (AC220V) of the charger is consistent with the grid voltage.
●Pay attention to charging the battery in the open area.
● Check whether the charger output plug is loose or not. When charging, first connect the charger output plug to the
battery pack charging interface, then connect the charger power plug to the household AC220V power supply, and the indicator
light is red. This procedure is not allowed to reverse operation.
●When the "charging" indicator lamp is normally charged, the charging indicator lamp will show " red". When the indicator
lamp shows " green", it means that the battery is fully charged, and the battery can be put into use at this time.
●Chargers and wire covers are strictly prohibited from heavy pressure to avoid short circuit.
It is forbidden to put wet rain gear and charger into the bucket in rainy days.
●The charger adopts constant current and constant voltage intelligent charging method to charge. According to
the different discharge depth of the battery, the lithium battery can normally be fully charged within 5 hours.
After the battery is full, unplug the charger power plug first, then unplug the charger output plug.
●When not charging or charging is completed, be sure to unplug the charger.
18 19

Warning:
▲All operation should be strictly conform to the user manual. If not, result will be assumed by user.
▲Must use original charger
▲Pay attention to the type of battery and applied voltage. Mixture use is forbidden.
▲Charging should be in ventilated environment. DO NOT charge in closed space or under high temperature.
DO NOT put charger into trunk or tail box while charging.
▲While charging, connect battery with charger before connect with electric supply. After full charged,
cut off the electric supply before cut off the battery plug.
▲When the green light turns on, please cut off the power in time. Avoid long time connection between charger
and AC power supply while not charging.
▲While charging, if the signal light is abnormal, has different smell or the charger is over temperature,
please stop charging immediately and check or change the charger in time.
▲When using and storing the charger, please avoid foreign matter, especially water or other liquid in case of internal
short circuit. DO NOT bring charger within scooter, if have to, please make sure of damping.
▲DO NOT disassemble or change the parts in charger by yourself.
Attention:
▲If the battery can not be fully charged after 12 hours, please stop charging and contact your dealer.
▲To maximize the battery life, please keep the battery percentage within 20% to 80%.
▲For storage, please keep the battery under 40°C to prevent irreversible capacity loss of the battery.
▲Z3 battery will lose more capacity in lower temperature conditions.
To be more specific, the usable capacity at -10°C is 70%, 85% at 0°C and 100% at 25°C.
▲The best battery capacity performance for storage is 50%. Storing battery with less than 10% or
more than 90% over a long period of time will cause irreversible capacity loss to the battery.
▲The battery needs to take out from the scooter for storage longer than one week. In this condition,
please keep the battery at the temperature of 0°C to 20°C with capacity of 30%-70%. It's advised to
have at least one cycle of charge and discharge every 2 months to minimize battery capacity loss during storage.
If the battery failure is due to misuse or lack of proper maintenance as instructed, its warranty will be invalidated.
▲Falling may cause uncontrollable internal damage to the battery and may cause leakage, overheat,
smoking, fire or explosion.

Before Riding: Please check the following details before riding.
Check Point
1.Steadiness
2.Steering flexibility
3.No axial displacement or loosening
1. Braking lever has 5 to 9mm idle travel.
Adequate for planned distance to travel
Check all the lights—High Beam, Low Beam, Brake Light,
Turn Signal Indicator, etc
Check whether the horn can work
1.The air pressure range of both tires is 25 to 34psi
2.Proper tyre tread depth
3.No cracks or openings
Description
DOs and DON'Ts while Riding DOs and DON'Ts while Riding
Braking Precautions
Adjust the scooter upright before applying brakes.
If the tyres are locked and the scooter lose steering ability resulting from excessive braking force,
loosen the grip on the braking lever and the tyres will be working again and the scooter will be stabilized.
Try to maintain a 1:1 ratio of front and rear braking force on slippery roads.
Attention:
Inexperienced riders tend to use the rear brake only, which will accelerate the wear of the brake
and result in a longer braking distance.
Warning:
Using the front brake or rear brake only is dangerous because of possible grip or control loss.
Pay extra attention and use the brakes gently when riding on damp, slippery roads and around corners.
Otherwise, riders will be exposed to great danger.
