SAFETY INSTRUCTION
OPERATION OF SCOOTER
1. To prevent injury to yourself or others, always ensure that the power is switched off
when getting on or off of the scooter.
2. Always check that the drive wheels are engaged (drive mode) before driving.
(Fig.1)
3. Do not switch off the power when the scooter is still moving forward. This will bring the
chair to an extremely abrupt stop.

General
1. Always use a seat belt, and keep your feet on the scooter all the time.
2. Do not over load the scooter with it’s maximum weight capacity of 160 kg (350 lbs)
3. Do not attempt to lift or move a power scooter by any of its removable parts. Personal
injury and damage to the power chair may result.
4. Never try to use your scooter beyond its limitations as described in this manual.
5. Do not operate your vehicle if it is not functioning properly.
6. Do not connect any electrical or mechanical device to the scooter. Failure to obey this
instruction may result in injury and will void the warranty.
7. Never use electronic radio transmitters such as CB, walkie-talkies, portable computers
or cellular phones while using the vehicle without first turning the scooter off.
8. Any transportation on a slope maybe dangerous if the automatic brakes are
disengaged.
Usage While Under The Influence Of Medication Or Alcohol
1. Check with your physician if you are taking any medication that may affect your ability to
operate your power scooter safely.
2. Do not operate your scooter while you are under the influence of alcohol, as this may
impair your ability to operate your power scooter in a safe manner.

Electromagnetic interference (EMI) from Radio Wave Sources
The rapid development of electronics, 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 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 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 power scooter like the S12. Power wheelchairs and motorized
scooters (in this section, both will be referred to as powered wheelchairs) 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 cause the powered wheelchair to release its brakes, move
by itself or move in unintended directions. 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 protection. At this time,
current technology is capable of providing at least 20 V/m of immunity level, which would
provide useful protection 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:
1. Do not turn on hand-held personal communication devices such as citizens band (CB)
radios and cellular phones while the powered scooter is turned on.
2. Be aware of nearby transmitters such as radio or TV stations and try to avoid coming
close to them.
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 modifying the powered scooter,
may make it more susceptible to interference from radio wave sources
(Note: It is difficult to evaluate the effect on the overall immunity of the powered
scooter).
5. Report all incidents of unintended movement or brake release to the powered scooter
manufacturer, and note whether there is a radio wave source nearby.

7
TURN OFF YOUR POWERED SCOOTER AS SOON AS POSSIBLE WHEN
EXPERIENCING THE FOLLOWING:
‧Unintentional scooter movements
‧Unintended or uncontrollable direction.
‧Unexpected brake release
The FDA has written to the manufacturers of power scooters asking them to test new
products to be sure they provide a reasonable degree of immunity against EMI. The FDA
requires that a powered wheelchair should have an immunity level at least 20 V/m, which
provides a reasonable degree of protection against more common sources of EMI. The
higher the immunity level the greater the protection. Your powered scooter has an immunity
level of 20 V/m which should protect against common sources of EMI.
Warning: The scooter itself can disturb the performance of the electromagnetic fields such
as emitted by alarm systems of shops.

ENVIRONMENTAL CONDITIONS
Environmental conditions may affect the safety and performance of your power scooter.
Water and extreme temperatures are the main elements that can cause damage and affect
performance.
A) Rain, Sleet and Snow
If exposed to water, your power scooter is susceptible to damage to electronic or
mechanical components. Water can cause electronic malfunction or promote premature
corrosion of electrical components and frame.
B) Temperature
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℃.
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.
