The battery gauge comprises five different LEDs (1x red, 2x amber,
2x green), situated above the remote module’s horn button.
The number of LEDs lit depends on the status of the battery.
The battery gauge LEDs are also used to display charging
information.
High Voltage Warning
A high voltage warning is indicated by all LEDs on, and the green
LEDs flashing. This occurs when the battery voltage level has risen
above the high voltage warning set-point.
Low Voltage Warning
A low voltage warning is indicated with the left-most LED flashing.
This occurs when the battery voltage level has decreased below its
low voltage warning set-point.
Cut-off Voltage
When the battery voltage decreases below the battery cut-off voltage:
- The status indicator will flash
- The first (red) LED will flash on the battery gauge
- The horn will sound once every 10 secends
The status indicator is located underneath the power button.
When the system is not powered up, the status indicator is not lit.

The electric wheelchair is a sophisticated mobility vehicle. Like any motorized
vehicle, it requires routine maintenance checks.
You can perform some of these checks, but others require assistance from an
authorized provider. Preventive maintenance is very important. If you follow the
maintenance checks in this section as scheduled, you can help ensure that your
wheelchair gives you years of trouble-free operation. If you have any doubt as to
your wheelchair’s care or operation, contact an authorized provider.
WARNING! Direct of prolonged exposure to water or dampness could cause the
electric wheelchair to malfunction electronically and mechanically. Water can
cause electrical components to corrode and the chair’s frame to rust. Electric
wheelchair should be examined periodically for signs of corrosion caused by
water exposure, bodily fluids exposure, or incontinence. Damaged components
should be replaced or treated immediately.
What should you do when your electric wheelchair touched water?
1.Dry your electric wheelchair as thoroughly as possible with towel.
2.Allow your electric wheelchair to sit in a warm, dry place for 12 hours to allow
unseen water to evaporate.
3.Check the joystick operation and the brakes before using your electric wheel
chair again
4.If any inconsistencies are found, take your electric wheelchair to your authorized
provider. Electric wheelchair that is frequently exposed to sources of water,
such as incontinence, should be inspected often for corrosion and electronic
components may need to be replaced frequently.
Temperature
Some of the parts of your electric wheelchair are susceptible to extreme changes
in temperature. Always keep your electric wheelchair between the temperatures of
-20°C and 50°C.
In extremely cold temperatures the batteries may freeze. The specific temperature
at which they freeze depends on a number of factors, such as battery change,
usage, and composition of the batteries.
Temperature about 50°C may cause your electric wheelchair to operate at a
reduced speed. This reduced speed is a safety feature built into the controller that
helps prevent damage to the motor and other electrical components.
Care and Maintenance

15
General Guidelines
Avoid knocking or bumping the controller, especially the joystick. Avoid prolonged
exposure of your chair to extreme conditions, such as heat, cold, or moisture.
Keep the controller clean
Check all connectors to ensure that they are all tight and secured properly. WARN-
ING! Even though the electric wheelchair has passed the necessary testing require-
ments for ingress of liquids, you should keep electrical connections away from
sources of dampness, including direct exposure to water or bodily fluids and inconti-
nence. Check electrical components frequently for signs of corrosion and replace as
necessary.
Daily Checks
With the controller turned off, check the joystick. Make sure it is not bent or damaged
and that It returns to the neutral position when you release it, Check the rubber boot
around the base of the joystick for damage. Visually inspect the boot. Do not handle
or try to repair it, See an authorized provider if there is a problem.
Visually inspect the controller cable. Make sure that it is not frayed, cut, or has any
wires exposed. See an authorized provider if there is a problem.
Check for flat spots on solid tires. Flat spots could adversely affect stability.
Weekly Checks
Disconnect and inspect the controller from the power base. If there is any corrosion,
contact and authorized provider if necessary.
Ensure that all parts of the controller system are securely fastened to your electric
wheelchair.
Calibrate the joystick if a noticeable difference in performance is detected or if the
joystick does not operate properly.
To calibrate the joystick, power off the unit, place the joystick in the neutral position,
and power the unit back on. .If a problem still exists with your joystick’s performance,
contact an authorized provider.
Check the brakes. This test should be carried out on a level surface with at least 3
feet (1 meter) of clearance around your Z-Chair.
Check the brakes.
1. Turn on the controller and turn down the speed level of your electric wheelchair.
2. After one second, check the battery condition meter. Make sure that it remains on.
3. Slowly push the joystick forward until you hear the electric brakes click.
Immediately release the joystick. You must be able to hear each electrical brake
operating within a few seconds of joystick movement. Repeat this test three times,
pushing the joystick backwards, then left, and then right.

16
Monthly Checks
Check for drive tire wear. See an authorized provider to repair. Keep your electric
wheelchair clean and free of foreign material, such as mud, dirt, hair, food, drink etc.
Yearly Checks
Take your electric wheelchair to an authorized provider for yearly maintenance,
especially if you use your chair on a regular basis. This helps ensure that your
electric wheelchair is functioning properly and helps prevent future complications.
Storage
Your electric wheelchair should be stored in a dry place, free from temperature
extremes. When storing, disconnect the batteries from the wheelchair.

and the electronics can be damaged.
Batteries that are regularly an deeply discharged, infrequently charged, stored in
extreme temperatures or stored without a full charge may be permanently damaged,
causing unreliable performance and limited service life. It is recommended that you
charge the batteries periodically throughout periods of prolonged storage to ensure
proper performance.
You may wish to place several boards under the frame of your electric wheelchair to
raise it off of the ground during periods of prolonged storage. This take the weigh off
of the tires and reduces the possibility of flat spots developing on the areas of the
tires contacting the ground.

parts of your electric wheelchair. Avoid using products that may scratch the surface
of your electric wheelchair. If necessary, clean your product with and approved

whole wheel assembly; If your wheelchair is equipped with a beach tire, which
maximum charge pressure or pressure range is 2Kpa. When you replace the beach
tire to solid tire, you must exchange the whole wheel assembly. Replacement wheel
assemblies are readily available through an authorized provider.
WARNING! Be sure that the controller’s power is turned off and the electric wheel-
chair is not in freewheel mode before performing this procedure.
