10. Please ride with caution and keep a safe distance on the road with rain, oil and snow to
prevent tires from slipping and rollover.
11. Please slow down and be careful when turning or reversing.
12. Please do not use the music entertainment system when driving the scooter, for it may
cause distraction and traffic accident.
13. Please do not overload.
14. Please power off the scooter when it is not in use to prolong the service life of the battery
and protects you from accident.
15. Please do not charge under the exposure of sun in the summer charge the battery indoors in
winter when the outdoor temperature is lower than 10℃.
About Modifications
We have designed and engineered the power scooter for the maximum service life. However, under no
circumstances should you modify, add, remove, or damage any part or function of the power scooter,
otherwise, personal injury and damage to the mobility scooter may result in. Please use original
accessories provided by us, untested or inapplicable accessories may lead to the breakdown.
Inspections prior to using your power scooter

1. If the scooter is equipped with pneumatic tires, proper tire pressure should be ensured before using it.
2. Please check all electric connections and make sure they are well connected and undamaged.
3. Please check all the harness connections and make sure that they are secured properly.
4. Please check the brake system and make sure that they are in good condition.
Load limitation
1. Please refer to the specifications table for weight capacity information. Mobility scooter is limited for
a maximum weight capacity.
2. Stay within the specified weight capacity for your scooter. Overload will make your warranty void
and we will not take responsibility for your injuries or property damage resulting from failures to
observe weight limitation rules.
3. Don't carry passengers on the scooter designed only for one driver. Carrying passengers on the
scooter may result in the change of the gravity center, and finally may causes rollover or tilt.
Tire pressure
1. If your scooter is equipped with pneumatic tires, it is necessary to check the air pressure at least one
time a week.
2. Proper inflation pressures will prolong the life your tires and ensure the smooth operation while
riding.
3. Do not under-inflate or over-inflate your tires. It is critically important that 30-25 psi (2-2.4bar) tire
pressure be maintained in pneumatic tires at all times.
4. Inflating your tires from an unregulated air source could over-inflate them, resulting in a burs tire.
Temperature
1. Some parts of the mobility scooter are susceptible to changes of temperature. The controller can only
operate safely between -25℃and 50℃.
2. The batteries may freeze at extremely low temperature, and your mobility scooter may not be able to
run at such low temperature. If at extremely high temperatures, it may operate at lower speed due to a
safety feature of the controller that prevents the motor and other electrical components from
damages.

ELECTROMAGNETIC INTERFERENCE (EMI)
The rapid development of electronic technology, especially in the area of communications, has saturated
our environment with electromagnetic (EM) radio waves that are emitted by television, radio and
communication signals. These EM wave is invisible and their intensity increases as source increase. All
electrical conductors act as antennas to the EM signals and to varying degrees, all the power wheelchairs
and scooters are susceptible to electromagnetic interference (EMI). The interference could result in
abnormal, unintentional movement and/or erratic control of the vehicle. The United States Food and
drug Administration (FDA) suggests that the following statement be incorporated to the user's manual for
all scooters like S800. Mobility scooters may as susceptible to electromagnetic interference (EMI), which
is interfering electromagnetic energy emitted from sources such as radio stations, TV stations, amateur
radio (HAN) transmitter, two-way radios, cellular phones and alarm systems of shops. The interference
(from radio wave sources) can make the scooter release its brakes, move by itself or move in unintended
directions. It may also permanently damage the scooter's control system. The intensity of the EM energy
can be measured in volts per meter (V/m). Each scooter can resist EMI up to a certain intensity, which is
called interference resistance capacity, and the scooter has an interference resistance capacity of 20 v/m
which would provide useful protection against common sources of radiated EMI.
the warnings listed below can reduce unintended brake release or uncontrolled move that may result in
serious injuries:
1. Do not use portable CB transceiver or communication device like cell phone when the scooter is
started.
2. Be careful and stay away from electromagnetic wave release equipment like radio, TV station, or
etc.
3. If unintended movement or brake release occurs, turn the powered scooter off as soon as it is safe.
4. Be aware that adding accessories or components, or refitting the scooter may make it more
susceptible to interference from radio wave sources (Note: It is difficult to evaluate the effect on the
overall interference resistance capacity of the mobility scooter).
5. Please report all the incidents of unintended movement or brake release to the manufacturer of the
mobility scooter and note whether there is radio wave source nearby.
