GENERAL WARNING
IMPORTANT
Do not attempt to use the scooter before a qualified person has
explained to your satisfaction how to operate it without risk to yourself
or others.
WARNING
● Do not operate this equipment without first reading and understanding
this manual. If you are unable to understand the warnings, cautions and
instructions, contact a dealer, healthcare professional or technical
personnel if applicable before attempting to use this
equipment--otherwise, injury or damage may result. Procedures other
than those described in this manual must be performed by a qualified
technician.
The information contained in this document is subject to change
without notice.
WARNING
● As a manufacturer of powered scooters, KARMA endeavors to supply a
wide variety of powered scooters to meet the many needs of the user.
However, the responsibility of final selection of the type of powered
scooter to be used by an individual rests solely with the user and his/her
healthcare professional capable of making such a selection.
KARMA recommends that powered scooter users NOT be transported in vehicles of
any kind while in a powered scooter. It is the position of Karma that users of powered
scooters should be transferred into appropriate seating in vehicles for transportation
and apply the restraints made available by the auto industry. Karma cannot and does
not recommend any powered scooter transportation systems.
It is the responsibility of the Durable Medical Equipment (DME) Dealer, therapists
and other healthcare professionals to determine if a seat positioning strap is
required to ensure the safe operation of this equipment by the user. Serious injury
can occur in the event of a fall from a powered scooter.

II
Operating Information
● Performance adjustments should ONLY be made by professionals of the
healthcare field or persons fully conversant with this process and the driver's
capabilities. Incorrect settings could cause injury to the driver or bystanders and
damage to the powered scooter and surrounding property.
● To determine and establish your particular safety limits, practice bending, reaching,
mounting and dismounting activities in several combinations in the presence of a
qualified healthcare professional BEFORE attempting active use of the powered
scooter.
● For individuals with balance problems, practice mounting and dismounting
activities WITH AN ASSISTANT in the presence of a qualified healthcare
professional. If so equipped, DO NOT operate the scooter without anti-tippers
being installed. Anti-tippers MUST BE attached at all times.
● DO NOT attempt to reach objects if you have to move forward in the seat or pick
them up from the floor by reaching down between your knees as this may cause
loss of balance.
● DO NOT lean over the back of the chair to reach objects behind you as this may
cause the powered scooter to tip over.
● DO NOT shift your weight or sitting position toward the direction you are reaching
as the powered scooter may tip over.
● DO NOT use an escalator to move a powered scooter between floors. Serious
bodily injury may occur.
● DO NOT operate in car lanes on roads, streets, highways, etc.
● DO NOT attempt to move up or down an incline with a water, ice or oil film.
● DO NOT attempt to ride over curbs or obstacles. Doing so may cause your
powered scooter to turn over and cause bodily harm and/or damage to the
powered scooter.
● DO NOT make sharp turns, in forward or reverse, at excessive speeds.
● DO NOT attempt to lift the powered scooter by its casings and seat.
● DO NOT attempt to lift the powered scooter by any detachable parts. Lifting by
means of any detachable parts of a powered scooter may result in injury to the
user or damage to the powered scooter. Please hold onto the frame when lifting
your scooter.
● DO NOT operate the powered scooter until you have checked that the
surroundings are clear and that the area is safe for travel.
● Please pay attention to the environment, and to keep away from the hazard of
external flame. When the user is smoking, pay attention to safety and make sure to
extinguish the fire when finished. Be alert to the environment when someone
nearby is smoking or using a cigarette lighter, keep away from the hazard and use

III
fire-proof cloth.
● DO NOT use parts, accessories or adapters other than those authorized by Karma.
Before attempting to sit in or exit the powered scooter, turn the power OFF. This
will ensure that the powered scooter will not drive. Turn the power OFF while the
scooter is not in use. Otherwise, injury and/or damage to the scooter and
surrounding property may occur.
● DO NOT connect any medical device (i.e., a ventilator, life support machine, et
cetera) to the battery. This could cause unexpected failure of the device and the
powered scooter.
● KARMA specifically disclaims responsibility to all personal injury and property
damage that may occur during use which does not comply with applicable federal,
state and local laws and ordinances.
● DO NOT stand on the footplates of the powered scooter.
● DO NOT use the scooter when the back is folded. This alters the centre of gravity
and may cause the scooter to tip backwards. The back should only be folded for
storage or transport of the scooter.
● DO NOT hang anything on the backjoints that could cause the backrest to fold
suddenly and may cause injury.
● DO NOT tow the scooter by other vehicles(cars, motorcycles or bicycles, etc.). Only
use freewheel mode on flat surfaces since your electromagnetic brakes are not
engaged in this mode, without these brakes it will roll down a hill causing injury or
damage. Never drive under the influence of alcohol or medication.
● DO NOT sit in the powered scooter within a moving vehicle unless it has been
affixed with the labels of hook mark. The labels of hook mark means that the
powered scooter fulfils the performance requirements for a “Crash Test” of ISO
7176-19 and is suitable to use as a seat in vehicles that have been adapted for this
purpose.
WARNING
● As of this date, the KS-7 series have NOT been tested for safety in
collisions according to ISO 7176-19. Therefore, the KS-7 series cannot be
used as seats in any vehicles. That is, KARMA recommends that users are
NOT transported in any vehicle while seated in the scooter. In the case of
accident or a sudden stop, the user could be thrown from the scooter
and get injured. The suggested solution is to transfer the user from the
scooter into a normal seat of the vehicle and to securely stow the scooter
in a separate compartment.

IV
RAMPS
● DO NOT climb, go up or down ramps or traverse slopes greater than the max. safe
slope angle for your model specified in Section 10.
● When negotiating ramps, if the joystick is released while moving forward, the
powered scooter will roll backwards approximately one foot before the brake
engages. If the joystick is released while in reverse, the powered scooter will roll
backwards approximately two and a half feet before the brake engages.
● Be sure to reduce your speed when driving on curved roads or making a turn; do
not drive at full speed. Please drive at a slower speed so you have complete
control of the scooter.
ELECTRICAL
● Check to ensure that all electrical connections are secure at all times.
● Grounding Instructions: DO NOT, under any circumstances, cut or remove the
round grounding prong from any plug. Some devices are equipped with
three-prong (grounding) plugs for protection against possible shock hazards.
Where a two-prong wall receptacle is encountered, it is the personal responsibility
and obligation of the customer to contact a qualified electrician and have the
two-prong receptacle replaced with a properly grounded three-prong wall
receptacle/outlet in accordance with the National Electrical Code and local laws.
● Do not use a n extension cord when charging your batteries. A risk of fire and /or
electric shock could be encountered.
BATTERIES
● The warranty and performance specifications contained in this manual are based
on the use of deep cycle sealed lead acid batteries.
● KARMA strongly recommends their use as the power source for this unit. (Refer to
Section 6)
● Carefully read the battery and charger information prior to installing, servicing or
operating your scooter.
RAIN TEST
● KARMA has tested its powered scooter in accordance with ISO-7176 Part 9 Rain
Test. This test provides the end user or his/her attendant sufficient time to remove
his/her powered scooter from a rainstorm and retain operation.
● DO NOT leave your powered scooter in a rain storm of any kind.
● DO NOT use your powered scooter in a shower or leave it in a damp bathroom
while taking a shower.

V
● DO NOT leave your powered scooter in a damp area for any length of time. Direct
exposure to rain or dampness could cause the powered scooter to malfunction
electrically and mechanically and may cause the powered scooter to prematurely
rust.
WEIGHT LIMITATION
● The maximum weight that can be carried,
including any items carried on the scooter, is
stated beside " Max. User Weight " in Section
10. SPECIFICATIONS
STAIRWAYS
● DO NOT attempt to move an occupied powered scooter between floors using a
stairway. (See Figure 1)
● Use an elevator to move an occupied powered scooter between floors. If moving a
powered scooter between floors by means of a stairway, the occupant MUST be
removed and transported independently of the powered scooter. Extreme caution
is advised when it is necessary to move an UNOCCUPIED powered scooter up or
down stairs.
● Karma recommends disassembling the scooter and transporting the components
independently up or down stairs. Make sure to use ONLY secure, non-detachable
parts on each component for hand-hold supports.

3. EMI/RFI
This section provides the user with basic information about the problems with EMI,
known sources of EMI and protective measures either to reduce the possibility of
exposure or to minimize the degree of exposure. This section also shows some
conditions in which unexpected or erratic scooter movements may occur.
CAUTION
●It is very important that you read this information regarding the possible effects
of electromagnetic interference on your electric KARMA Scooter
3.1 Electromagnetic Interference From Radio Wave Sources
3.1.1 Powered vehicles may be susceptible to electromagnetic interference (EMI),
which is interfering electromagnetic energy (EM) emitted from sources such as
radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios,
and cellular phones. The interference (from radio wave sources) can cause the
powered vehicle to release its brakes, move by itself, or move in unintended
directions. It can also permanently damage the powered vehicle's control
system. The intensity of the interfering EM energy can be measured in volts
per meter (V/m). Each powered vehicle can resist EMI up to certain intensity.
This amount of resistance is called its immunity level. The higher the immunity
level, the greater the protection. At this time, current technology is capable of
achieving at least a 20 V/m immunity level, which would provide useful
protection from the more common sources of radiated EMI. This powered
vehicle model, with no further modification, has an immunity level of 20 V/m
without any accessories.
3.1.2 There are a number of sources of relatively intense electromagnetic fields in
our everyday environment. Some of these sources are obvious and easy to
avoid. Others are not apparent and exposure could be unavoidable. However,
we believe that by following the warnings listed below, your risk to EMI can be
greatly minimized.
3.2 The sources of radiated EMI can be broadly classified into three types.
3.2.1 Hand-held portable transceivers (transmitter-receivers) with the antenna
mounted directly on the transmitting unit, such as citizens band (CB) radios,

8
walkie-talkies, security and fire or police transceivers, cellular telephones and
other personal communication devices;
NOTE:
Some cellular telephones or similar devices transmit signals while they are ON, even
though they are not in use.
3.2.2 Medium-range mobile transceivers used in police cars, fire trucks, ambulances
and taxis usually having the antenna mounted on the outside of the vehicle;
and
3.2.3 Long-range transmitters and transceivers, such as commercial broadcast
transmitters (radio and TV broadcast antenna towers) and amateur (HAM)
radios.
NOTE:
Other types of hand-held devices (cordless phones, laptop computers, AM/FM radios,
TV sets, CD players, cassette players, and small appliances such as electric shavers
and hair dryers, et cetera) so far as we know, are not likely to cause EMI problems.
3.3 Powered Vehicle Electromagnetic Interference (EMI)
Because EM energy rapidly becomes more intense as one moves closer to the
transmitting antenna (source), the EM fields from hand-held radio wave sources
(transceivers) are of special concern. It is possible to unintentionally bring high
levels of EM energy too close to the powered vehicle's control system while using
these devices. This can affect your powered vehicle's movement and braking.
Therefore, the warnings listed below are recommended to prevent possible
interference with the control system of the powered vehicle.
3.4 Warnings
Electromagnetic interference (EMI) from sources such as radio and TV stations,
amateur radio (HAM) transmitters, two-way radios and cellular phones can affect
powered vehicles and motorized scooters.
Following the warnings listed below should reduce the chance of unintended brake
release or powered vehicle movement which could result in serious injury.
3.4.1 Do not operate hand-held transceivers-receivers such as citizens band (CB)

9
radios or turn ON personal communication devices such as cellular phones,
while the powered vehicle is turned ON.
3.4.2 Be aware of nearby transmitters, such as radio or TV stations, and try to stay
away from them.
3.4.3 If unintended movement or brake release occurs, turn the powered vehicle
OFF as soon as it is safe.
CAUTION
●Some stores may have automatic (sensor) doors and alarm systems set at
certain frequencies that might affect your powered scooter
3.4.4 Be aware that adding accessories/components or modifying the powered
