SAFETY INSTRUCTION
Operation of Chair
1. Always ensure that the power is switched off when getting in or out of the wheelchair. This will
eliminate the possibility of accidentally activating the joystick and causing injury to yourself or
others.
2. Always check that the drive wheels are engaged (drive mode) before driving.
3. Set the speed control knob according to your driving ability and the environment in which you are
going to operate. We recommend that you keep your speed at the slowest position (fully press the
deceleration button) until you are familiar with the driving characteristics of the vehicle. We also
recommend that you use the slowest speed when using your power wheelchair indoors.
4. Always reduce your speed when making sharp turns.
5. Do not switch off the power when the wheelchair is still moving forward. This will bring the chair
to an extremely abrupt stop.
6. Avoid jerky stop/start motions as the will result in excessive current draw from the batteries,
increased tire wear and the rapid wearing of the gear boxes and motors.
7. To brake in an emergency, simply release the joystick.
Ramps and Curbs
8. When driving up or down ramps, be sure to check that the angle of the slope is less than 10
degrees (slopes about 1/6). Also check that ramp surface is roughened to prevent slipping. Never
drive across the slope or turn sharply on a slope.
9. When driving up curbs, always check the height of the curb to ensure that it does not exceed
1-1/2” height.
Transfers, Reaching and Bending
10. Transferring on and off the HP7K requires a good sense of balance. To eliminate the possibility
of injury, we recommends performing the following tasks before attempting a transfer:
→Position chair so that the distance between your power chair and the object to which you are
transferring is close enough for a safe transfer.
→Turn the power off
→Ensure that your power chair not in freewheel mode.
→Flip up or remove armrests
→Flip up footplate or remove footrests
→Turn both caster wheels towards the transfer direction to improve power chair stability during
transfer.
11. When reaching, bending or leaning while seated on your power chair, make sure that you
maintain a stable center of gravity to keep the power chair from tipping.

General
12. Always use a seat belt, and keep feet on the footplate at all the time.
13. For safety reasons, make sure that your weight does not exceed the recommended weight limit of
the wheelchair. Consult your dealer for the specified weight limits for your particular model.
14. Do not attempt to lift or move a power chair by any of its removable parts. Personal injury and
damage to the power chair may result.
15. Do not stand on the footplate directly.
16. Never try to use your wheelchair beyond its limitations as described in this manual.
17. Do not operate your vehicle if it is not functioning properly.
18. Do not connect any electrical or mechanical device to the vehicle. Failure to obey this instruction
may result in injury and will void the warranty.
19. Never use electronic radio transmitters such as CB, walkie -talkies, portable computers or
cellular phones while using the vehicle without first turning the vehicle off.
Use While Under the Influence Of Medication OrAlcohol
20. Check with your physician if you are taking any medication that may affect your ability to
operate your power wheelchair safely.
21. Do not operate your vehicle while you are under the influence of alcohol, as this may impair your
ability to operate your power chair 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 approaches
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 wheelchairs like the HP-7S. 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 and cellular phones. 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 wheelchair’s control system. The intensity of the EM energy can
be measured in volts per meter (V/m).Each powered wheelchair can resist EMI up to a certain
intensity. This is called “immunity level”. The higher the immunity level is, the greater the protection

is. 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 wheelchair 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 wheelchair is turned on.
2. Behold 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 wheelchair off as soon as it is
safe.
4. Behold that adding accessories or components, or modifying the powered wheelchair, 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 wheelchair).
5. Report all incidents of unintended movement or brake release to the powered wheelchair
manufacturer, and note whether there is a radio wave source nearby.
TURN OFF YOUR POWERED WHEELCHAIR AS SOON AS POSSIBLE WHEN
EXPERIENCING THE FOLLOWING:
‧Unintentional motions
‧Unintended or uncontrollable direction.
‧Unexpected brake release
The FDA has written to the manufacturers of power wheelchairs 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 is, the greater the
protection is. Your powered wheelchair has an immunity level of 20 V/m which should protect
against common sources of EMI.
