10. Maintenance
1. Cleaning and storage
Please clean i-walk in time after use to maintain the best performance. Wipe the i-walk with a damp cloth, use a nozzle to wash
the tires and fenders (water pressure< 1 Mpa, or 145PSI).
Dry in a ventilated place to avoid corrosion. Stains or scratches on plastic surfaces that are difficult to clean can be brushed
with toothpaste.
When not in use, try to store it in a dry and cool place indoors, and try to avoid storing it outdoors for a long time. Sun
exposure/overheating/over-cold outdoor environment will accelerate the appearance and tire aging of the i-walk electric scooter,
and will also affect the service life of the battery.
Tips:
When cleaning the i-walk scooter, make sure your scooter is turned off and the rubber cover of the charging port is covered,
otherwise it may cause electric shock or serious failure; It may lead to the accumulation of water vapor or water in the car,
resulting in serious irreparable failures;
Do not use alcohol, gasoline, kerosene, acetone or other corrosive and volatile chemical solvents to clean the car body. These
substances will damage the appearance and internal structure of the car and cannot be repaired.
2. Battery pack maintenance
The battery pack is the most important part of the i-walk. To extend your battery life as much as possible, follow the instructions
below:
• Carefully read the precautions on the battery pack surface label and follow the instructions;
• Please try to keep the battery pack at 0 ℃~ 40 ℃room temperature drying environment,
high temperature and low temperature environment will affect the battery life. Please avoid below -20 ℃or higher than 50 ℃
in the use of the environment of the battery;
• Please try to store the battery pack in a dry, cool environment. In a closed wet environment, the battery pack may will get
water, but also can cause the battery pack to be damaged quickly. If the environment cannot be avoided wet, please use a
large self-styled bag sealed the battery pack;

12
• In daily use, try to avoid completely running out of the batteries. Please charge as soon as possible when the dashboard
indicates that only 10% ~ 20% is left. Battery capacity and life will be seriously affected if the battery is in a state of exhaustion
for a long time. When the dashboard shows that there are only 1 to 2 bars left, please charge it as soon as possible. Try to fully
charge the battery after each ride, frequent charging will not damage the battery life, and the battery is close to being
exhausted for a long time will also seriously affect the battery capacity and life;
Tips:
In general, a fully charged scooter will deplete its stored power after about 90 to 100 days of standby, and a nearly depleted
battery installed in the scooter will deplete its power after about 10 to 20 days of standby, at which time if not charged in time, it
is likely that the battery will be damaged by excessive discharge. This damage is not recoverable and no warranty is provided.
(Note: non-professional personnel are prohibited from disassembling the battery pack; Otherwise it may cause serious safety
accidents due to electric shock or short circuit!)
