Battery disassembly prohibited
Battery disassembly, modification, and repair are not covered under warranty.
Safety precautions for Lithium battery
1) Care Lithium batteries should be protected from direct exposure to children and pets.
2) Performance 1. Lithium battery is affected by external temperature. In the winter, when the temperatures are low, the performance of the battery may be temporarily deteriorated and the mileage and power
output is reduced.
2. Lithium battery has a characteristic that discharge performance is reduced by more than 15% when charging / discharging 300 times or more. If usage time is shortened due to long usage, it should be
replaced with a genuine one through the nearest point.
3) Charging 1. Lithium battery should be used only with genuine battery and charger supplied from the manufacturer. Any problems caused by use of battery made by the manufacturer, mixed use, or using the
charger are not covered by the manufacturer.
2. Charging the lithium battery with a non-genuine charger may cause malfunction or fire.
3. The lithium battery should be charged in a well-ventilated, dry place and around the charger in a place where there is no flammable material.
4. Lithium battery should be charged at 0 ~ 45°C and discharged within -10 ~ 60°C . The sub-battery must be charged at 0 to 50°C and discharged within -20 to 75°C. Charging or discharging at a temperature
outside this range may cause malfunction, fire or explosion.
5. In case of moving from cold outside to warm indoor, please charge it after 1 ~ 2 hours. This is to prevent condensation from occurring inside the product due to the temperature difference.
4) Storage 1. Lithium batteries should be kept away from snow, rain and direct sunlight. Do not store or charge them in a trunk or hot room. Select a dry place and store at room temperature (10 ~ 20℃).
2. When storing for more than 3 months, charge the remaining battery levelto 70 ~ 80% (do not store full charge).
5) Trouble symptom, safety 1. Lithium battery should be discontinued immediately if it is damaged or there is leakage of battery, sour odor, appearance deformation, etc. Please contact the place of purchase to
get technical support and service.
2. If overheat, smoke, or ignition is detected in a product with lithium battery, immediately stop charging and use, move the product outdoors as soon as possible, and then use a fire extinguisher to extinguish
flames. Do not spray water or immerse the product in any situation, which can lead to more danger.
3. Lithium battery pack has very high energy density, so if you charge the battery for a long time and there is a case of short-circuit, leakage, bad battery, etc., it can lead to ignition. Therefore,you should
avoidcharging for a longtimewithout a personbeing present to avoid therisk of unexpected fire.
6) Misuse If the lithium battery is short-circuited, the polarity is changed, or if the battery is impacted, malfunction or fire may result. If you think that the battery has been impacted, you should stop charging and
using it and visit the nearest service center for inspection.
7) Water inflow It should be controlled to prevent water inflow into the lithium battery. There is a risk of fire or electric shock if the charger is connected while moisture is present.
8) Caution Disconnect the battery from the main unit except when recharging and reinstalling. Do not use for any other purpose.
9) Disposal When disposing of the lithium battery, the battery should be separated from the product at the point of purchase or near the service center and the charge and discharge terminals are not
shortcircuited. Dispose of it as industrial waste.

pads grabs the rotor.
2) Tighten the bolts on the caliper. The suggested torque is 8.5±0.5 N·m.
3) Release the brake levers, spin the wheels. If the brake pads make contact with the rotor,
loosen the bolts on the caliper and repeat step 1.
4) The pushrod can be adjusted by a 2 mm wrench if necessary. Rotate the pushrod
clockwise to increase the length between the brake lever and the handlebar. Rotate the
pushrod counterclockwise to decrease the length.
The disc brake has the function of self-repairing. But when the brake pads are significantly
worn, they need to be replaced.
If the brake levers feel spongy when you squeeze them and the rotor makes abnormal
sounds, please stop riding immediately and replace them with the new brake pads.
