Battery and Charger
Charger Requirements
Charger Requirements
The charger is used for battery charging. During electric wheelchair is
charging, do not use it. Charger Technical Data
Input voltage: AC220V (110V) ±10%
Output voltage: 24V/DC Output current: 1.5~5AIngress protection level is
IPX1. The charger should meet the requirement of GB 4706.1-2005 and GB
4706.18-2005.
Usage of Charger
Type 1 (charge directly in battery) In order to charge the battery, connect
the charger with power supply and battery box’s plug. Do as following
instructions to complete charging process:
Step 1: Make sure the charger groove is not blocked.
Step 2: Make sure the electric wheelchair is power off.
Step 3: Unplug the plugs which connect the battery box and controller.
Step 4: Connect the charger’s output plug to the battery box’s power
plug.
Step 5: Connect the charger’s main plug to the power supply and the
red light will be alight. Fully charging needs 8 to 10 hours, do not
overcharge more than 24 hours.
Step 6: As to prevent cut short battery life, please charge the
battery at least once per month when the wheelchair is not being used.
Type 2 (charge through controller) In order to charge the battery, connect the
charger with power supply and controller socket. Do as following instructions
to complete charging process:
Step 1: Make sure the charger groove is not blocked.
Step 2: Make sure the electric wheelchair is power off.
Step 3: Make sure the battery and controller are connected.
Step 4: Connect the charger’s output plug to the socket below the
controller.
Step 5: Connect the charger’s main plug to the power supply and the red
light will be alight. Fully charging needs 8 to 10 hours, do not overcharge
more than 24 hours. Step 6: As to keep the battery life from being shortened,
please charge the battery at least once per month when the wheelchair is not
being used.
**** Do not stop charging until charge process is finished. Repeat using of battery which is not fully charged will shorten the battery life, so the battery should be fully charged as much as possible. When battery is fully charged, the power indicator will turn to green. Do not stop charging before fully charged. After finish charging, turn off the power supply, otherwise the battery will discharge slowly. Do not charge more than 24 hours. Over-charging is dangerous.
Users should follow the following rules to avoid charging dangers: The
electric wheelchair doesn’t include the charger, please use national standard
charger that the output voltage is 24V/DC 1.5A~5A. It should be well
ventilated when charging. Do not expose the wheelchair to sunlight and humid
environment. The charging environment temperature range is from 10℃ to 50℃. If
it is out of the environment temperature range, the battery is unable to
function well, and can easily make battery damaged.
It’s normal for the fan making a sound during charging. It is for cooling the
charger, please do not worry about it. Prevent liquid go into the charger
during charging. And do not place charger on the flammable items, such as:
fuel, footrest or seat cushion. Please stay away from the flames when charging
the battery. The flames may cause battery fire or explosion.
Charging makes hydrogen, do not smoke while charging. Do not unplug the power supply when the socket or your hands are wet, it may cause electric shock. In case of unpredictable accident will happen and hurt the user, do not use or sit on the electric wheelchair when charging.
The Usage and Maintenance of Battery
Wrong operation of replacing battery may cause danger of explosion. Only the same or recommended type of battery is suitable for replacement. And please make sure the battery poles a re correct. Key points for prolong the battery life: charge frequently, to keep battery power full. It’s better to fully charge the battery if the wheelchair is not being used. If stop using for a long time, it’s better to charge twice per month.

Controller Usage
Power Switch
Press this button, the battery power gauge lights will turn on from left to right. Press again, all the LED lights are off.
In some emergency, you can directly turn off power by press power button
Sleep Mode
If the joystick has no operation more than 20 minutes, the power turn off automatically, and the system in the sleep mode, system will be woke up from sleep mode by press power button.
Speed adjustment
According to user’s habits and the circumstances, the wheelchair driving speed
is adjustable. Adjust speed by press decrease button or increase button.
Speed is
divided into five sections, ranged by 20%, 40%, 60%, 80%, 100% of the max
speed.
First gear of speed: 20% of the max speed.
Fifth gear of speed: 100% of the max speed.
Horn Button
Press the horn button, the horn will sounds until you release the button.
Battery Power Gauge
After turn on the power, the battery power gauge is working. The battery power
gauge also shows the battery remaining power capacity. As the picture shown,
the battery power is full.
When there is only the red or yellow LED light lit, the battery should be
charged. And for a long distance driving, the battery should be fully charged.
If only the red LED light is lit, the battery power is extremely inadequate,
users need to charge battery as soon as possible.
Use of joystick
The wheelchair moving direction is controlled by joystick. The moving extent of joystick also controls the moving speed.
Please turn on or turn off the power when the joystick is in the middle position. Otherwise the controller will let out wrong operation signal. Release the joystick to middle, this mistake will stop. If the mistake is still continuing, perhaps this part is malfunction, do not use it and contact with your dealer for maintenance.
Maintenance
Maintenance of wheelchair includes clean wheelchair, check wheel and battery, and charge battery. For further maintenance please contact with your dealer. Our suggestion is checking the wheelchair every half year, annually overhaul.
Clean and Battery Maintenance
Clean Wheelchair
Please clean the wheelchair regularly. Clean the parts which are frequently
touched with user’s body (such as set cushion, armrest, controller) by a clean
and slight wet cloth. Do not use organic solvents to clean. If it is a patient
user, the wheelchair should be cleaned once per week. If the wheelchair is
used by an infectious victim, it should be cleaned and disinfected by
disinfectants.
Wheels
Check the tires’ air pressure and their wear condition regularly. When the
tire tread pattern depth reduce to 1mm, please replace new tire.
Battery
To make sure that the battery is fully charged frequently. In order to prolong
battery life, we strongly recommend users do not to charge until battery run
out of power totally.
Wheelchair Malfunction and Checking
When malfunctions happen during the wheelchair is working, please turn off the power before check. Symptom: completely lose power, and all the LED lights on the controller panel are off.
Check Step:
Step 1: To check if the controller’s plug is loose.
Step 2: To check if the connection of controller’s plug and battery box
is loose. Please reinsert the plug connector (hold the plug when pull out the
plug. Do not pull the wire to avoid unnecessary damage to the wire line).
After above checking, if the wheelchair is still not able to restore the
power, or if users have any question for above checking, please connect with
your dealer.
The controller has a diagnosing system to monitor the controller and motor. Any malfunction of these parts is indicated by the controller. For more details please kindly refer to chapter of audio signal indication.

Recommended separation distances between portable and mobile RF
communications equipment and the ELECTRIC WHEELCHAIR
The ELECTRIC WHEELCHAIR is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of
the ELECTRIC WHEELCHAIR can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the ELECTRIC WHEELCHAIR as recommended below,
according to the maximum output power of the communications equipment

For transmitters rated at a maximum output power not listed above the
recommended separation distance d in metres (m) can be estimated using the
equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies. NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
