V. Maintenance and Repair
◆Maintenance:
1. To check if there’s any rusty part or leaks carefully. Leaks may be eroded
to accelerate damage and enlarge the leaks itself.
2. To clean dbRevO wheel periodically and keep away from all corrosive
materials such as salt.
3. Do not polish, drill or carve on wheel surface. Leaks may be caused by
large scratch, chisel hole or nick.
4. Users shall pay attention to find out noise source if any, and try to solve
the problems as soon as possible.
5. It is strictly prohibited to wash the wheel by strong spout to avoid
damaging the battery. Users shall clean the wheel by clean mop.
6. Users shall use neutral or soft detergent to avoid damaging the wheel
housing.
7. It is strictly prohibited to clean the wheel by sea water or salty water. Users
shall use cold water to avoid corrosion problems.
8. It is suggested to park the bicycle indoor or at cool places to avoid being
exposed to the sun and rain. Users shall keep the wheel dry to avoid rusty
problems. .
