1.1 Important safety instructions before using e-drive

For safety reasons e-drive must only be operated by people who:

• Have received instruction on using e-drive

• Are in good physical and psychological health, so as to be able to control e-drive

safely in all operating situations. Instruction on operating e-drive is included in the scope of the delivery and will be provided at a time agreed through your specialist dealer or a Decon Wheel representative. This service is completely free of charge. If you still do not feel safe using e-drive, please contact your specialist dealer e-drive has been programmed to suit you by your local dealer. The performance shall not be changed because it will effect the road performance and be dangerous for you Adhere to all the values the wheelchair manufacturer has specified in the directions for use, particularly maximum clearance limits. Also carefully follow the operating and safety instructions in the directions for use of the wheelchair. Always switch e-drive off and activate the parking brake before moving to or from the wheelchair. e-drive is dimensioned for indoor and outdoor use, but a basic prerequisite is that you travel on a stable surface.

Despite e-drive being dimensioned in accordance with all current EMC directives, electromagnetic fields may affect driving characteristics. Mobile phones and other devices that emit electromagnetic radiation can in certain cases cause incorrect function. Likewise, e-drive may cause disturbances in electromagnetic fields. This is rare, though it can lead to triggering of alarms in older alarm installations, e.g. in department stores, or to opening of older automatic doors.

Make sure you are in a safe place and switch e-drive off, before using a mobile phone or a similar device. Avoid driving in the proximity of strong electric fields as traffic lights, electrical wires and transformers that can cause interference. E-drive can by itself create electrical and radio waves. E-drive can disturb electrical equipment. It can cause interference on equipment in a hospital or other places that have electrical instruments.

On no account start e-drive up before receiving instruction from your specialist dealer or a Decon Wheel representative.

Installing the e-drive

Your local dealer shall have mounted all necessary components on your wheelchair. If you receive the chair without the wheels mounted on the chair, follow the instructions as you see below. If the wheels does not fit on the chair, contact your local dealer.

1. Start fitting e-drive to your wheelchair. The wheels have a quick release axle (QR axle). Press the button and assembly the wheel on the chair. Picture 1

2. When installing the wheels you need to lift the wheelchair up a little with your hand. Then insert the QR axle . It is very important that the axle be pressed in far enough; otherwise the QR axle may come off. Picture 2 and 3

Overturn protection

Before you start using e-drive for the first time you must check that the overturn protection is fitted to your wheelchair.

For safety reasons you should only remove the overturn protection in order to get over an obstacle, e.g. a high kerb. The assistance of another person will then be necessary. The installation instructions supplied with your wheelchair must be observed when fitting and removing the overturn protection.

GUIDE FOR SAFE DRIVING

When you get your chair with e-drive fitted to it, it is important that you check how it works in a safe and calm place. As an e-drive user, you decide which routes you can manage as far as your driving ability and physical ability are concerned. Before using e-drive, make sure that the tyres are not worn or damaged and that the batteries are fully charged. These safety checks and your driving abilities are important when assessing whether you can get around using e-drive in the following places:

• Quays, landing sites and moorings, roads and locations by watercourses, jetties and

dams without protective rails.

• Narrow roads, slopes (e.g. ramps and approaches), narrow roads close to precipices,

mountainous areas.

• Narrow and/or steep/sloping paths by busy roads or near to precipices.

• Leaf- and snow-covered or icy stretches.

• Ramps and lifting devices.

Warning

With e-drive you can manage uphill and downhill slopes in accordance with the wheelchair manufacturer's specifications. The basic prerequisites are tyres that are not worn, the correct tyre pressure, a risk-free surface and a maximum user weight of 120 kg.

You will need help when you have to negotiate:

• Kerbs requiring the wheelchair to tilt by over 15%.

• All kinds of obstacle more than 50mm, on slopes, as the risk of overturning then

increases.

• When you exceed the turning radius of 1600 mm

Be extremely careful when crossing busy roads and at railway and other crossings. Never drive parallel to tram and railway tracks when trying to cross them, as there is a risk of the wheels getting stuck in the tracks. It's better to get someone to help you who can quickly push the wheelchair over the street or railway crossing if the wheelchair suddenly stops (e.g. if the batteries have no charge).

Be careful when driving up ramps onto vehicles. When lifting and lowering, e-move must be disconnected and the parking brakes must be activated.

On wet surfaces the tyres have less grip on the road and there is an increased risk of skidding. Always adjust your driving to the situation at hand.

TRANSPORT AND DISASSEMBLY

Your e-drive is easy to get ready for transport.

Battery

1. Remove the battery by pressing button (A) whilst carefully pulling the battery out of its holder (Figure l).

Cable

2. Remove the cable from the socket by turning it whilst pulling it carefully upwards (Figure 2).

Wheels

The wheels are removed by pressing the button. Picture1 and 2 pull straight outward. Take care when removing the right -hand wheel. The battery holder and switch can easily start to rotate if you do not hold one of them whilst loosening the wheel. Be carefully with the e-drive wheels when you transport them so they don’t become exposed for any hits or knocks.

If you should transport the wheelchair with the e-drive installed, do not hold the pushrim, battery or cable when lifting the wheelchair. This may cause damage to the unit.

Nickel Metal Hydride Battery

3.1 Characteristics

1. This is an earth-friendly battery, offering a very high energy density, that does not contain lead, mercury, or cadmium.

2. It has a Battery Management Control (BMC) system that uses a computer to keep track of charge/discharge status, operating conditions, and temperature.

3. Although it is susceptible to the memory effect that reduces its discharge capacity when it is subjected to shallow charge and discharge cycles, it can be solved by refresh charging it periodically.

4. It has LED lamps to indicate the battery’s residual capacity. It uses an absolute capacity indication system that indicates capacity in accordance with the extent of the battery’s deterioration.

5. Recommended ambient temperatures

Recommended operating temperature range: 0°C to 35°C ambient temperature Recommended storage temperature range: 10°C to 25°C ambient temperature Recommended charging temperature range: 10°C to 25°C ambient temperature

6. The capacity of the battery will deteriorate naturally regardless of whether it remains unused or stored properly. Even if it is used correctly, its performance will deteriorate and its absolute capacity will decrease gradually with the extent of use and the passage of time.

Characteristics due to the use environment

• Compared to traveling on a level surface, frequent travel uphill and over curbs will consume more power and reduce the travel range.

• Due to the characteristics of the battery, the travel range may be reduced due to changes in ambient temperature, which affect the temperature of the battery.

Battery’s deterioration characteristics

• Although the extent of reduced capacity varies by operating conditions, it will decrease to approximately 60% of the capacity of a new battery after 300 charge/discharge cycles.

• Storing the battery at temperatures other than the recommended range will accelerate deterioration, particularly at high temperatures.

Example: Avoid storing a battery inside an automobile or luggage compartment in the summer.

Recycling the battery

This is a recyclable battery that contains valuable resources. Contact the e-drive dealer to recycle your used batteries.

Proper use of the battery

NOTE

• Charge the battery in a cool area that is not exposed to direct sunlight. If the temperature of the battery is too high, charging might not start

or might not nish.

• Even if it is subjected to shallow charge and discharge cycles, the memory effect can be solved by refresh charging the battery periodically.

• Deep discharges that use up the battery’s capacity will overload the battery and shorten its use life.

• If you use more than one battery, use them alternately because their performance will deteriorate over time even if they remain unused.

• Store batteries in a cool, dry area. Fully charge a battery that you do not plan to use for a long period of time. 23

NOTE

Even if the battery is used correctly, its performance will deteriorate gradually. This battery uses an absolute capacity indication system, which, after the battery is charged, lights the indicator lamps in accordance with the extent of the battery’s deterioration.

Residual capacity lamp indication system

Characteristics of the absolute indication system After the battery’s performance level deteriorates gradually to below 80%, the fifth lamp will not light even after the charging is completed. After it deteriorates further to below 60%, the fourth lamp will also not light. Because this system gives an absolute indication of the residual capacity in accordance with the extent of deterioration of the battery, it can accurately indicate the residual capacity.

3.3 Charging

Please read the following instructions thoroughly before charging a battery.

n

Charging location

A battery can be charged as long as its temperature range is between 0°C and 40°C. However, to ensure the life of the battery, the following conditions are recommended.

• Indoors, in a cool, well ventilated place.

• Where the temperature can be kept between 10°C to 25°C while charging.

• A level and stable location.

CAUTION

Avoid charging in the following places.

Example 1: High-temperature locations exposed to direct sunlight or near a stove. In cold regions,

where the temperature drops to below zero.

*Charging will not start when the battery temperature is too high or too low.

Example 2: Outdoor locations exposed to rainfall or near a sink where the battery may get wet.

*This may cause equipment failure or electric shock due to a short circuit.

Example 3: Within reach of children or pets.

*May cause injury or damage to the equipment.

CAUTION

Do not place any objects on or around the charger while charging, as this may cause the charger to overheat and adversely affect its performance.

Use of specified equipment

WARNING

Use only the specied charger to charge the battery. Failure to do so may cause a re or damage to the battery.

Operating temperature

• To protect the battery, the charger will not start charging if the battery temperature is not within the 0°C to 40°C range. The charge lamp (green) will continue to flash until the battery reaches an appropriate temperature. When the battery reaches an appropriate temperature, the charge lamp will light and charging will start automatically. (The length of the standby time varies with the conditions.)

• After the refresh charging (discharging) of the battery is completed, the charger may go into the charge standby mode, causing the green lamp to flash. Once the battery reaches an appropriate temperature, this lamp will light and charging will start automatically.

• The battery temperature increases during charging. However, the charger will be forced to stop charging if the battery temperature exceeds 50°C. Since charging has not ended normally, it is necessary to charge again after the battery temperature has decreased.

• Charging a battery immediately after travel or charging a new battery is likely to cause its temperature to increase, which forces the charger to stop charging. Since charging has not ended normally, it is necessary to charge again after the battery temperature has decreased.

Handling

WARNING

Do not drop or apply a sharp impact to the battery or charger, as it may cause a malfunction.

Step

Connect the power cord to a power source.

Hold the power cord by its plugs and connect it to the charger and to a power source.

Install the battery in the charger.

Insert the battery into the battery slot of the charger until it is fully seated. If the battery is at an appropriate temperature, the charge lamp (green) will light and charging will start.

Step

Check the capacity indicator lamps.

During charging, the capacity indicator lamps on the battery light successively to indicate the progress of charging. The charging of a discharged battery is completed in 2.5 to 3 hours. Then, the charge lamp on the charger and the capacity indicator lamps on the battery will go out automatically.

Step

Check the charging condition.

After charging is completed, press the indicator switch on the battery to check the lighting condition of the lamps.

CAUTION

As the battery’s performance level deteriorates, some of the indicator lamps will no longer light even though

charging has been completed. First, the fth lamp fails

to light, then the fourth, and so on. If both the fth and

fourth lamps no longer light after charging has been completed, the battery should be replaced.

3.3.2 Refresh Charging

When the refresh lamp (orange) flashes and informs you of the need to refresh charge the battery:

Step

Press the refresh switch.

While the refresh lamp is flashing (approximately 10 seconds), press the refresh switch and confirm that the refresh lamp has lighted. The charger will start discharging the battery.

NOTE

Even if you fail to press the refresh switch, you can retry by momentarily removing the battery from the charger, and then reinserting the battery to see the refresh alert.

Step

Check the charging condition.

During discharging, the capacity indicator lamps on the battery will go out successively to inform you of the progress of the discharge. When the discharge is completed, charging will start automatically. The process to the completion of charging is the same as in rapid charging.

CAUTION

• After the refresh charging (discharging) of the battery is completed, the charger may go into the charge

standby mode, causing the green lamp to ash. Once

the battery reaches an appropriate temperature, this lamp will light and charging will start automatically.

• If you continue to disregard the refresh charge alerts and do rapid charges instead, the capacity indicator lamps on the battery may go inaccurately. Make sure to refresh the battery before the third refresh charge alert.

• If you do not refresh charge even if you see the refresh charging alert, the alert will subsequently appear each time you attempt to charge.

NOTE

• Refresh charging normally takes 3 to 13 hours. (In case of a high temperature, it may take longer.) It takes a shorter time to refresh charge a battery that the battery is low level.

• It is a good idea to start a refresh charge before you go to sleep. Then, the battery will be discharged by the morning and thus

can be charged efciently.

• Even if the charger alerts you to do a refresh charge, you may disregard it if you wish to charge immediately. After approximately 10 seconds, the charger will automatically start a rapid charge.

Lithium Ion Battery

4.1 Characteristics

1: This is an earth-friendly battery, offering a very high energy density, that does not contain

lead, mercury, or cadmium.

2: It has a Battery Management Control (BMC) system that uses a computer to keep track of the

charge/discharge status, operating conditions, and temperature of the battery.

3: It is not susceptible to the memory effect even if it is subjected to shallow charge and

discharge cycles. It is unnecessary to refresh charge this battery, whose charge can be replenished.

4: It has LED lamps to indicate the battery’s residual capacity. This battery has a large capacity,

and deteriorates only moderately. It uses a relative capacity indication system that lights all

the lamps each time a charge is completed. 5: Recommended ambient temperatures Recommended operating temperature range: 0°C to 35°C ambient temperature Recommended storage temperature range: 10°C to 25°C room temperature Recommended charging temperature range: 10°C to 25°C room temperature 6: The capacity of the battery will deteriorate naturally regardless of whether it remains unused

or is stored properly. Even if it is used correctly, its performance will deteriorate and its

absolute capacity will decrease gradually with the extent of use and the passage of time.

Characteristics due to the use environment

• Compared to traveling on a level surface, frequent travel uphill and over curbs will consume more power and reduce the travel range.

• Due to the characteristics of the battery, the travel range may be reduced due to changes in ambient temperature, which affect the temperature of the battery.

Battery’s deterioration characteristics

• Although the extent of reduced capacity varies by operating conditions, it will decrease to approximately 60% of the capacity of a new battery after 700 charge/discharge cycles.

• Storing the battery at temperatures other than recommended will accelerate deterioration, particularly when a fully charged battery is stored at high temperatures. Example: Avoid storing a battery inside an automobile or luggage compartment in the summer.

Recycling the battery

This is a recyclable battery that contains valuable resources. Contact the JW dealer to recycle your used batteries.

Proper use of the battery

NOTE

• Charge the battery in a cool area that is not exposed to direct sunlight.

• About once or twice each month, leave the battery connected to the charger for 8 to 12 hours after it is charged. The charger will replenish the charge automatically. (The charger will automatically turn off its internal power approximately 12 hours after the charge lamp goes out.)

• Store batteries in a cool, dry area. Before storing a battery for a long period of time, charge it until 2 to 4 of its lamps are lighted. Do no store it with only 1 lamp lighted or fully charged.
