3. Don't carry passengers on scooters. Carrying passengers on scooter may affect the center of
gravity, resulting in a tip or a fall.
◆ Tire inflation
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 of the parts of the power scooter are susceptible to change in temperature. The controller
can only operate in temperature that ranges between -25℃ ~ 50℃.
2.
At extreme low temperatures, the batteries may freeze, and your power scooter may not be able
to operate. In extreme high temperatures, it may operate at slower speeds due to a safety feature
of the controller that prevents damage to the motors and other electrical components.
ELECTROMAGNETIC INTERFERENCE (EMI)
The rapid development of electronics, especially in the area of communica6ons, has saturated our
environment with electromagne6c (EM) radio waves that are emi=ed by television, radio and
communica6on signals. These EM wave are invisible and their strength increases as one approach
the source. All electrical conductors act as antennas to the EM signals and, to varying degrees, all
power wheelchairs and scooters are suscep6ble to electromagne6c interference (EMI). The
interference could result in abnormal, uninten6onal movement and/or erra6c control of the vehicle.
The United States Food and drug Administra6on (FDA) suggests that the following statement be
incorporated to the user's manual for all power scooters like the S12, S12T, S12S, S12X. Power
scooters may as suscep6ble to electromagne6c interference (EMI), which is interfering
electromagne6c energy emi=ed from sources such as radio sta6ons, TV sta6ons, amateur radio
(HAN) transmi=er, two-way radios, cellular phones and alarm systems of shops. The interference
(from radio wave sources) can cause the power scooter to release its brakes, move by itself or move
in unintended direc6ons. It can also permanently damage the powered scooter's control system. The
intensity of the EM energy can be measured in volts per meter (V/m).Each powered scooter can
resist EMI up to a certain intensity. This is called "immunity level". The higher the immunity level the
greater the protec6on. At this 6me, current technology is capable of providing at least 20 V/m of
immunity level, which would provide useful protec6on against common sources of radiated EMI.
Following the warnings listed below should reduce the chance of unintended brake release or powered
scooter movement that could result in serious injury:
Do not turn on hand-held personal communica6on devices such as ci6zens band (CB) radios and cellular
1.
phones while the powered scooter is turned on.
Be aware of nearby transmi=ers such as radio or TV sta6ons and try to avoid coming close to them.
2.
If unintended movement or brake release occurs, turn the powered scooter off as soon as it is safe.
3.
Be aware that adding accessories or components, or modifying the powered scooter, may make it more
4.
suscep6ble to interference from radio wave sources (Note: It is difficult to evaluate the effect on the
overall immunity of the powered scooter).
Report all incidents of unintended movement or brake release to the powered scooter manufacturer,
5.
and note whether there is a radio wave source nearby.
