SAFETY INSTRUCTION
!General
Always use a seat belt, and keep your feet on the
scooter all the time.
Never operate the scooter while you are under the
influence of alcohol.
Never use electronic radio transmitters such as
walkie-talkies, or cellular phones.
Make sure that there are no obstacles behind you
while reversing your scooter.
Do not make a sharp turn or a sudden stop while
riding your scooter.
Do not ride your scooter in traffic.

4
www.vitamobilitywerks.com
Do not attempt to climb curbs greater than
limitation show on Technical Specification
Do not leave your hands and legs off the scooter
when driving.
Do not ride your scooter during snow in order to
avoid accident on slippery road.
Do not allow unsupervised children to play near
this equipment while the batteries are charging.
!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 caution.
2. To prevent injury to yourself or others, always ensure that the power is switched off when getting
on or off 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.

5
www.vitamobilitywerks.com
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 VMW.
!Modifications
Vita Mobility Werks 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 VMW. Do not use accessories if
they have not been tested or approved for VMW products.

6
www.vitamobilitywerks.com
2. Get to know the feel of your power scooter and its capabilities. VMW 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. VMW 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.
