■Lock the seat into position before you operate your scooter.
■Do not operate your scooter with the seat in the reclined position (if so equipped).
■Make certain that the tyres are inflated to 30 pounds per square inch (psi). Overinflating a tyre can cause it to
explode, resulting in personal injury or damage to your scooter.
■Do not operate your scooter if you are taking medication which may impair your ability to operate your scooter
in a safe manner.
■Do not drive your scooter across the side of an incline or diagonally up or down an incline; avoid stopping whilst
driving on inclines.
■Keep both hands on the tiller and your feet on the floorboard at all times while operating your scooter. This
driving position gives you the most control over your vehicle.
■Proceed with extreme caution when driving near raised surfaces or unprotected ledges or drop-offs (kerbs,
porches, stairs, etc.)
■Drive slowly when turning.
■Secure the batteries before loading your scooter into another vehicle for transport.
■Disconnect the batteries if you are not going to operate your scooter for more than 48 hours.
■Do not operate or store your scooter where it may be exposed to inclement weather conditions such as rain,
snow, mist, and below-freezing temperatures. Attempting to operate your Scooter in such conditions may
damage the electronics and potentially result in loss of control.
■Always protect batteries from freezing temperatures and never charge a frozen battery. This damages the
battery and may cause personal injury. Attempting to charge a battery in freezing conditions does not prevent a
battery from freezing.
■Do not expose the electronics to any type of moisture at any time. Such exposure may damage the electronics.
Never attempt to ride a scooter that has been exposed to moisture until it has dried thoroughly.
■Never sit on your scooter when it is being used with any type of lift/elevation product. Your scooter was not
designed with such use in mind, and any damage or injury incurred from such use is not the responsibility of the
manufacturer.

ELECTROMAGNETIC INTERFERENCE (EMI)
This portion of the manual will provide the user with basic information about the problems with
EMI (electromagnetic interference), protective measures can be used to either lessen the
possibility of exposure or to minimize the degree of exposure; this section also shows some conditions that
unexpected or erratic movements may cause.
Caution
It is very important that you read this information regarding the possible effects of
electromagnetic interference on your electric mobility scooter.
ELECTROMAGNETIC INTERFERENCE (EMI) FROM RADIO WAVE SOURCES
Mobility scooters 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 mobility scooter to release its brakes, move by itself, or move in unintended
directions. It can also permanently damage the mobility scooter’s control system. The intensity of the
interfering EM energy can be measured in volts per meter (V/m). Each mobility scooter can resist EMI up to
a certain intensity 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 mobility scooter model as shipped,
with no further modification, has an immunity level of 20 V/m without any accessories.
There are a number of sources of relatively intense electromagnetic fields in the everyday
environment. Some of these sources are obvious and easy to avoid. Others are not apparent and exposure is
unavoidable. However, we believe that by following the warning listed below, your risk to EMI will be
minimized.
The sources of radiated EMI can be broadly classified into three types:
1. Hand-held portable transceivers (transmitter-receivers with the antenna mounted directly on the
transmitting unit). Examples include: citizens band (CB) or hand held radios, (security, fire, and police
transceivers), cellular telephonesand other personal communication devices.
NOTE: Some cellular telephones transmit a signal while they are ON but not being used.
2. Medium-range mobile transceivers, such as those used in police cars, fire trucks, ambulances and taxis usually
have the antenna mounted on the outside of the scooter.
3. Long-range transmitters and transceivers, such as commercial broadcast transmitters
(radio and TV broadcast antenna towers) and amateur (HAM) radios.

KR8000 Mobility Scooters Owner’s Manual
7 | P a g e
NOTE: Other types of hand-held devices, such as cordless phones, laptop computers, AM/FM Radios. TV sets, CD
player, and cassette players, and small appliances, such as electric shavers and hair dryers, are not likely to cause
EMI problems to your mobility scooter.
MOBILITY SCOOTER ELECTROMAGNETIC INTERFERENCE (EMI)
EM energy rapidly becomes more intense as one moves closer to a 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 very close to the mobility scooter’s control system while using these
devices; this can affect your scooter’s movement and braking. Therefore, the warnings listed below are
recommended to prevent possible interference with the control system of a mobility scooter.
Warning
Electromagnetic interference (EMI) from sources such as radio and TV stations amateur
radio (HAM) transmitters two-way radios and cellular phones can affect mobility scoters.
Following the warning listed below should reduce the chance of unintended brake
release or mobility scooter movement which could result in serious injuries.
1. Do not operate hand-held transceivers-receives such as citizens band radios or turn on personal communication
devise such as mobile phones while the mobility scooter is turned on.
2. Be aware of nearby transmitters such as radio or TV stations and try to avoid getting close to them.
3. If unintended movement or brake release occurs turn the mobility scooter OFF as soon as it is safe.
4. Be aware that adding accessories or components or modifying the mobility scooter may make it more
susceptible to EMI
5. Report all incidents of unintended movement or brake release to One Rehab Ltd and note whether there were
sources of EMI nearby.

BATTERIES & CHARGING
Your scooter use tow long-lasting 12-volt deep-cycle batteries that are sealed and maintenance free.
 Fully charge the batteries prior to using the scooter for the first time.
 FULLY CHARGE THE BATTEREIES AT LEAST ONCE A WEEK AS FAILURE TO DO SO WILL PERMANENTLY AND
SIGNIFICANTLY DAMAGE THE BATTERIES. THIS IS ESSENTIAL REGARDLESS OF THE SCOOTER’S USE.
FOLLOW THESE EASY STEPS TO CHARGE THE BATTERIES SAFELY
1. Position the scooter close to a standard electrical socket.
2. Remove the key from the key switch.
3. Make certain that the manual free-wheel lever is in the down (drive) position.
4. Plug the charger output cable into the charging socket on the scooter (see picture)
5. Extend the charger power lead and plug into the wall outlet
6. We recommend charging the batteries for at least 8-14hours
7. When the batteries are fully charged the orange LED light on the charger will turn to green.
8. When the batteries are fully charged unplug the charger power lead from the electrical
socket and unplug cable from the charging socket
9. Place the charger in a safe place for future use.
BATTERIES AND CHARGING - FREQUENTLY ASKED QUESTIONS (FAQS)
Can I use a different charger?
For the safest, most efficient, and balanced charging of the scooter’s batteries, we highly recommend the
simultaneous charging of both batteries together using the original battery charger.
What do the LEDs on the battery charger indicate?
The battery charger is equipped with two Light Emitting Diodes (LEDs) that indicate the charging status of the
batteries. The red LED indicates the battery charging is in progress. The green LED indicates the batteries are fully
charge.
How often must I charge the batteries?
■If the scooter is used daily, charge it every night. We recommend that you charge your scooter’s batteries for
8 to 14 hours after daily use.
■If you use your scooter once a week or less, charge its batteries at least once a week for 12 to 14 hours at a time.
■Keep your scooter’s batteries fully charged. Leaving your batteries partially discharged will damage the batteries.
■Avoid deeply discharging your scooter’s batteries. If batteries become completely discharged recharge them as
soon as possible.
■Do not charge the batteries for more than 24 consecutive hours.

KR8000 Mobility Scooters Owner’s Manual
14 | P a g e
How can I get maximum range or distance per charge?
■Always fully charge your scooter’s batteries prior to your daily use.
■Maintain the correct air pressure in your scooters tyres at all times.
■Plan your route ahead to avoid adverse terrain such as hills and uneven surfaces.
■Maintain an even speed while driving
What type and size of battery should I use?
We recommend deep-cycle batteries that are sealed and maintenance free. Both sealed lead-acid (SLA) and gel cell
are deep-cycle batteries that offer similar performance in your scooter. Do not use wet-cell batteries, which have
removable caps.
CAUTION! Do not remove the caps from sealed batteries. Water cannot be added to sealed batteries. Cap
removal voids the battery warranty and may cause damage to the batteries and to your scooter.
Use these specifications to reorder deep-cycle batteries:
Type：Deep-cycle (sealed lead-acid or gel cell)
Voltage：12-volts each
Amperage：36 AH
Approximate Size: 200mm x 170mm x 170mm
To change a battery
1. Remove seat and rear shroud. Please see Figure 8. “Disassembly and Assembly.”
2. Remove the battery tie-down strap.
3. Disconnect the battery cables from the electronic controller module.
4. Disconnect the battery cables from the battery terminals.
5. Remove the old battery.
6. Place a new battery in the battery well.
7. Connect the red battery cable to the positive (＋) battery terminal.
8. Connect the black battery cable to the negative (－) battery terminal.
9. Reconnect the battery cables to the electronic controller module.
10. Fasten the battery tie-down strap.
11. Replace rear shroud and seat.
Why do my new batteries seem weak?
Deep-cycle batteries employ a different chemical technology than is used in car batteries, nickel-cadmium batteries
(NiCad), or in other common battery types. Deep-cycle batteries are specifically designed to provide power, drain
down their charge, and then accept a relatively quick recharge.
We work closely with battery manufacturers to provide batteries best suited to the scooter’s specific electrical
demands. During shipping, the batteries may encounter temperature extremes that may influence their initial
performance. Heat diminishes the charge on the battery; cold slows the available power and extends the time
needed to recharge the battery.
It may take a few days for the temperature of your scooter’s batteries to stabilize and adjust to their new room or
ambient temperature.
More importantly, it takes a few charging cycles (a partial drain followed by a full recharge) to establish the critical
chemical balance that is essential to a deep-cycle battery’s peak performance and long life.

KR8000 Mobility Scooters Owner’s Manual
15 | P a g e
The following steps will maximise the batteries` life and efficiency:
1. Fully recharge any new battery prior to its initial use. This charging cycle brings the battery to about 88% of its
peak performance level.
2. Operate your new scooter in familiar and safe areas. Drive slowly at first, and do not travel too far from your
home or familiar surroundings until you have become accustomed to your scooter’s controls and have maximised
the capacity of the batteries.
3. Fully recharge the batteries. They should now be at over 90% of their peak performance level.
4. Operate your scooter again.
5. Fully recharge the batteries again.
6. After four or five charging cycles, the batteries are able to receive a charge of 100% of their peak performance
level and are able to last for an extended period of time.
How can I ensure maximum battery life?
Fully charged deep-cycle batteries provide reliable performance and extended battery life. Keep your scooter’s
batteries fully charged. Batteries that are regularly and deeply discharged, infrequently charged, or stored without
a full charge may be permanently damaged, causing unreliable performance and limited life. Such damage is not
covered by warranty.
How should I store my Scooter and its batteries?
If you plan on not using your scooter for an extended period of time, it is best to:
■Fully charge its batteries prior to storage.
■Disconnect the battery harnesses from the electronic controller module.
■Store your scooter in a warm, dry environment.
■Avoid storing your scooter where it will be exposed to temperature extremes.
WARNING! If your scooter’s batteries do become frozen, do not attempt to charge them.
Cold or frozen batteries should be allowed to warm up for several days prior to recharging.
For prolonged storage, you may wish to place several boards under the frame of your scooter to raise the scooter
off of the ground. This takes the weight off the tyres and prevents the possibility of flat spots developing.
What about public transportation?
If you intend to use public transportation while using your scooter, you must contact in advance the transportation
provider to determine their specific requirements.
