Warning –Don’t operate your scooter for the first time without completely reading and
understanding this user manual.
1. Don’t operate scooter on public streets and roadways. Be aware that it may be difficult for traffic
to see you when you are seated on the scooter. Obey all local pedestrian traffic rules. Wait until
your path is clear of traffic, and then proceed with extreme cautions.
2. To prevent injury to yourself or others, always ensure that the power is switched off when getting
on or off of the scooter.
3. Always check that the drive wheels are engaged (drive mode) before driving. Do not switch off
the power when the scooter is still moving forward. This will bring the chair to an extremely
abrupt stop.
4. Do not use this product or any available optional equipment without first completely reading and
understanding these instructions. If you are unable to understand the warnings, cautions or
instructions, contact a healthcare professional, the dealers or technical supports before attempting
to use this equipment, otherwise, injury or damage may occur.

4
5. There are certain situations, including some medical conditions, where the scooter user will need
to practice operating the scooter in the presence of a trained attendant. A trained attendant can be
defined as a family member or care professional especially trained in assisting a scooter user in
various daily living activities. Consult with your physician if you are taking any medication that
may affect your ability to operate your scooter safely.
6. Do not attempt to lift or move a power scooter by any of its removable parts including the
armrests, seats or shrouds. Personal injury and damage to the power chair may result.
7. Never try to use your scooter beyond its limitations as described in this manual.
8. Please do not sit on your scooter while it is in a moving vehicle.
9. Keep your hands away from the wheels (tires) while driving scooters. Be aware that loose fitting
clothing can become caught in the drive tires.
10. Consult your physician if you are taking prescribed medication or if you have any certain
physical limitations. Some medications and limitations may impair your ability to operate
scooters in a safe manner.
11. Be aware when the drive mode is unlocked or locked.
12. Don’t remove anti-tipper if there is any-tipper equipped with the scooter.
13. Contact with tools can cause electrical shock and do not connect an extension cord to the AC/DC
converter or the battery charger.
14. Do not attempt to lift or move your scooter by any of its removal parts, such as the armrests,
seats, or shroud.
15. When climbing an incline, don’t drive at an angle up the face of the incline. Drive your scooter
straight up the incline. This greatly reduces the possibility of a tip or a fall.
16. Don’t climb a slope steeper than the scooter’s limitation.
17. Don’t attempt to have your scooter proceed backward down any step, curb or other obstacle. This
may cause the scooter to fall or tip.
18. Always reduce your speed and maintain a stable center of gravity when cornering sharply. Don’t
corner sharply when driving scooters at higher speeds.
19. Operating in rain, snow, salt, mist conditions and on icy or slippery surfaces may have an adverse
affect on the electrical system.
20. Never sit on your scooter when it is being used in connection with any type of lift or elevation
product. Your scooter is not designed with such use in mind and any damage or injury incurred
from such use is not the responsibility of Heartway.
Modifications
Heartway Medical Product has designed and engineered power scooters to provide maximum utility.
However, under no circumstances should you modify, add, remove, or disable any part or function of
your power scooter. Personal injury and damage to the power chair may result.
1. Do not modify your power scooter in any way not authorized by Heartway. Do not use accessories
if they have not been tested or approved for Heartway products.

5
2. Get to know the feel of your power scooter and its capabilities. Heartway recommends that you
perform a safety check before each use to make sure your scooter operates safely.
Inspections prior to using your power scooter:
1. If equipped with pneumatic tires, please check for proper tire inflations.
2. Please check all electrical connections and make sure they are tight and not corroded.
3. Please check all harness connections and make sure they are secured properly.
4. Please check the brakes.
Weight limitation.
1. Please refer to the specifications table for weight capacity information. Power scooter is rated for a
maximum weight capacity.
2. Stay within the specified weight capacity for your scooter. Exceeding the weight capacity voids
your warranty. Heartway will not be held responsible for injuries or property damage resulting
from failure to observe weight limitations.
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 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 PF7S. Power 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 cause the power scooter
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.
