Charging Pot

2221
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.
UQi GT 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.
ATTENTION
DOs and DON'Ts while Riding
Please check the following details before riding.
Before Riding
Check Point Description
Steering Handlebar
Braking
Tyres
Battery
Lights
Horn
Braking lever has 5 to 9mm idle travel.
Adequate for planned distance to travel.
Check whether the horn can work.
Check all the lights—High Beam, Low Beam, Brake Light,
Turn Signal Indicator, etc.
(1) The air pressure range of both tires is 25 to 34psi.
(2) Proper tyre tread depth
(3) No cracks or openings
(4) Minimum load-capacity index: front 17, rear 43.
(5) Minimum-speed category: B.
(1) Steadiness
(2) Steering flexibility
(3) No axial displacement or loosening

2423
Adjust the scooter upright before applying brakes.
If the tyres are locked and the scooter loses 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.
Braking Precautions
Users are advised to have the scooter checked and maintained on a regular basis, even for the
scooters that are not used for a long time.
Maintenance and Repair
Users are advised to have their scooters checked 2 months after purchased or with 500 km
travelled distance. Overall check and maintenance is advised to be conducted every 6 months
or 3000 km thereafter.
Regular Maintenance
If any problem occurs during checks, please look through the Home Repair Instructions or send
the scooter to the dealer’s for checks and maintenance.
Daily Maintenance
Please use neutral detergent and water to wash the scooter. Use soft cloth to wipe the scooter
after washing to prevent scratching.
Scooter Washing

25 26
If the scooter is frequently used in overload, high-speed, bumpy or up/downhill riding
conditions, the maintenance cycle should be shortened.
