9. SYM Electric Scooter Q & A
1. How is the SYM electric scooter capability of riding across flooded road? Is the motor waterproof?
A: The motor is capable of being drenched, but the waterproof capability is not good when being soaked.
Do not ride across the flooded road when the water level is higher than the wheel rim (approximately
10cm high).
2. Can SYM electric scooter be ridden in the rainy day? How is the waterproof capability?
A：Yes, but do not ride across the flooded road when the water level is higher than the wheel rim
(approximately 10cm high), or the motor could possibly suffer from being soaked (the waterproof
capability of motor depends on the gasket adhesive; the waterproof capability can not be
guaranteed after disassembly). Spraying on the motor and wire harness with high-pressure water
is extremely prohibited, which will result in short circuit.
3. What will happen to the battery and motor if the vehicle is soaked in the water with the water level
higher than the footrest when the main switch is key-off? What will happen if the water level is higher
than the footrest when the main switch is key-on?
A：The motor, motor controller and DC-to-DC converter could be possibly damaged because of being
soaked when the water level is higher than the footrest. The damage would be worse if the main
switch is key-on. Only the battery could possibly survive damage, but might malfunction because
of short circuit caused by other parts’ damage.
4. Can SYM electric scooter carry passenger or cargo?
A：This vehicle can carry a passenger, but it is not recommended to carry cargo. Max passenger load:
150KG. Load increase will affect vehicle durability.
5. Battery charger input voltage？
A：Use the electrical socket (100V~240V)
6. How long is the charging period?
A：1. The battery needs to be charged 2-3 hours (20Ah)，The battery has no memory effect and could
be recharged overnight, In the situation that the ambient temperature or the battery temperature
too high (more than 55℃) or too low (less than 0℃), to avoid battery deterioration, the battery
will automatically prolong the charging time to 4-5 hours.
2. It is recommended to recharge after each ride to prolong battery service life.
3. In long time not in use, it is recommended to fully charge the battery every 3 months to prolong
battery service life.
7. Is there any side effect when the charger is still plugged to the electrical socket after the battery is
removed?
A: The charger will not be heated when it is plugged to the electrical socket, but would consume standby
power.
8. How much will the riding range decrease when the headlight is turned on?
A: Approximately 10~20% less.
