3 Product description

The power assist is a unique product giving manual wheelchair users additional power assistance, by just using one of the rims on the power assist wheels. The large Assist rim can be used as a conventional wheelchair push rim to manually propel the wheel. In case the power assist is switched on, the motor of the power assist will give power assistance while driving. The amount of support that is provided is dependent on the selected proﬁ le and the force applied to the rim. The smaller Drive rim provides continuous support and can be used to move forwards or backwards – in this case no manual propulsion is required. The power assist is very intuitive to use, but some practise and training is required for safe usage.

3.1 Main parts

The main parts of the power assist are illustrated (ﬁ gure 2). A. Sensor box B. Proﬁ le buttons C. Assist rim D. Drive rim E. Support blocks F. Anti-tip G. Battery pack H. Charge connector I. Wheel handle

11WheelDrive

3.2 The user

The power assist is developed for users of manual wheelchairs with a ﬂ uctuating or decreasing condition and/or strength in body or limbs.

The user must be able to estimate and correct the results of actions taken when operating the wheelchair. The user of the power assist should have experience with a manual wheelchair and must be able to use, drive, brake and handle a manual wheelchair without support.

Both left and right wheels work independently from each other. The power assist is not intended for one hand operation.

The user must be familiar with the contents of the user manual before driving the wheelchair. In addition, the user of the wheelchair must have been given thorough instruction in using the wheelchair by a qualiﬁ ed specialist before he or she participates in traﬃ c. The ﬁ rst sessions in the wheelchair with the power assist should be held under the supervision of a trainer/advisor. Please contact your dealer in case of questions.

Warning!

The user of the power assist is responsible for complying with the applicable local safety regulations and guidelines. Contact your dealer for information about regulations applicable to your usage conditions.

Driving with the power assist under the inﬂ uence of medicines that can aﬀ ect your ability to drive is not permitted.

Driving with the power assist without suﬃ cient eyesight is not permitted.

No more than one person is to be seated in a wheelchair with the power assist at a time.

Do not allow young children to drive unsupervised in a wheelchair with the power assist.

3.3 The wheelchair

The power assist is compatible with most common wheelchair frames in the market. The installation can be done with a number of standard parts, supplied with the power assist wheels. For each wheelchair frame model a diﬀ erent setting is needed. Once a wheel is set for a certain frame, it cannot be put directly onto another frame; an adjustment to the settings is required.

3.4 User environment

This power assist has been designed for both indoor and outdoor use (and as such is classiﬁ ed as a class B system according EN12184 (2009)). When driving the wheelchair with power assist outdoors, it is advised to drive on paved roads, pavements, footpaths and bicycle paths. Adjust the speed to suit the environment.

Caution!

Do not use the power assist when temperatures are below -10°C or above +40°C.

Only drive on ﬁ rm surfaces. Avoid loose gravel, sand, mud, snow, ice or deep puddles.

Drive carefully on roads which are slippery as a result of rain, ice or snow!

Clean the system after driving in wet weather by drying the product with a cloth or towel.

Do not drive through puddles of water – the power assist is so called splashing water proof (normal outdoor rain conditions). Never submerge any part containing electronics in liquids.

Prevent the power assist from coming into contact with sea water: sea water can cause corrosion and may damage the system.

Prevent the power assist from coming into contact with sand: sand can come into the moving parts of the system, causing unnecessary fast wear of these parts

12 WheelDrive

Warning!

It is advised to select a low driving proﬁ le when driving indoors, on pavements and in pedestrian areas.

Take extra care when driving at higher speeds.

Do not drive oﬀ obstacles higher than 50 mm.

Overcome obstacles only by driving backwards, if possible.

Do not attach any weights to the power assist system or wheelchair frame without the approval of a qualiﬁ ed specialist. This may negatively aﬀ ect the stability of the product.

It is advised to use fully charged batteries when driving up a slope (less charged batteries can supply less power than fully charged batteries). For taking slopes at least 2 LEDs of the battery indicator should be on.

Never use the Drive rims when driving up or down a slope (only drive up/down a slope using the Assist rims) and only in case you would feel comfortable doing so (even) with a manual wheelchair without power assist.

Take special care when driving down slopes of any kind. Adjust your speed to maintain safe control. If the speed exceeds approximately 10 km/h, the power assist will enable the ‘braking on the motor’ feature to limit the speed increase for safety reasons. As this may not happen simultaneously on both wheels we always recommend to keep permanent contact with the hand rims when driving downhill.

When descending with fully charged batteries at a too high speed, the power assist will switch- oﬀ automatically to avoid malfunctioning due to overvoltage (see paragraph 4.9). The wheels still can be used manually, but power assistance is not available anymore.

Beware that each power assist wheel is about 2 cm wider than a standard manual wheel; be careful taking narrow doors and hallways.

3.5 Software adjustment options

The electronics of the power assist are programmed to an average usage/driving proﬁ le – several parameters are available that can be adjusted to inﬂ uence the driving behaviour. Please contact your dealer about possible adjustments.

Warning!

Only an authorized person is allowed to make any adjustments and program the power assist.

14 WheelDrive

4.2 Charging the batteries

Only use the supplied battery chargers to charge the battery packs (ﬁ gure 4). The battery pack include electronics to control the charging process – it will disconnect the charger in case the batteries are fully charged; overloading is not possible. Each wheel has a separate battery. Both battery packs need to be charged separately. Both chargers can be used for both battery packs. Batteries can be charged when they are mounted on the power assist. Batteries can also be taken oﬀ for charging. To prevent you from getting into a situation where no power assistance is available, it is strongly recommended to charge both batteries every day. Each battery pack has a charge connector with a black cover. Open the cover and insert the plug with the ﬂ at side to the left (ﬁ gure 5).

In case the power assist is switched ON, the charging level of the main battery is indicated via the battery indication LEDs on the user interface (ﬁ gure 6).

Warning!

In case all battery indication LEDs are oﬀ when the power assist is turned on, this might be due to a system error. Please contact your dealer.

During charging the LED on the charger will turn red. When the battery is fully charged, the LED indicator of the charger will turn green. Now you can disconnect the plug. Please pull at the plug itself, not the cord. After disconnecting the plug, close the black connector cover to prevent water and dirt coming in.

The charger plug is not properly connected when the red light on the charger ﬂ ashes. Unplug the battery and reinsert it. If the light keeps ﬂ ashing please contact your dealer.

Caution!

Never subject the charger to humidity – only use it indoors.

Never charge the battery packs at temperatures below 0°C or above 30°C.

Do not store batteries at high temperatures (this will reduce the service life signiﬁ cantly).

Charge the battery pack completely before long-term storage, and check the charge level every 3 months. Even not-used batteries will discharge slowly; prevent the batteries to become completely empty (deep discharge of the batteries will damage the batteries).

Never pull the cable to remove the battery charger from the mains or charge connector.

Always attach the black connector cover if no battery charger is connected, to prevent water and dirt coming in.

Warning!

In case the batteries are completely empty the power assist will shut down automatically to prevent deep-discharge (and damaging) of the batteries. The wheels continue to run, but power assistance is not available anymore.

During charging the batteries of the power assist, no power assistance is available.

Do not drive with the power assist during charging the batteries if they are attached to the wheels.

Check your battery level before starting a ride.

4.3 Using the batteries

Removing the battery pack

Place your ﬁ ngers under the handle and pull it upward. This will unlock the battery pack (ﬁ gure

8).

Placing the battery pack

Place your ﬁ ngers under the handle and position the battery pack to the contacts of the electronic housing. Push the battery pack against the wheel until the battery pack audibly and perceptibly clicks into the electronics housing. Check if the battery is fully ﬁ xed in the electronics housing (ﬁ gure 9).

Warning!

Make sure the wheel hub and battery pack are clean and dry when inserting the battery pack!

With the battery pack removed, some openings are visible - do not push your ﬁ ngers in any openings to prevent possible injuries or damages.

4.4 Driving - using the rims

Assist rim (A in ﬁ gure 10)

This rim works the same as the rims on a manual wheelchair. By using these Assist rims the motor supports the forward and backward movement. The support level is dependent on the selected proﬁ le and force applied to the rim.

Assist rim usage

When applying more force on the Assist rims, the system will give more support. When less force is applied on the Assist rim, the system will give less support. In this way the required speed can be controlled.

Braking with the Assist rim

Braking with the Assist rim is comparable with braking with a manual wheelchair. When the system is on, the power assist oﬀ ers additional motor support when moving the rim backwards. The user is part of the braking system.

17WheelDrive

Warning!

The Assist rim is connected to a sensor. Do not use the Assist rim to lean on, for making a transfer from or to your wheelchair.

Drive rim (B in ﬁ gure 10)

This rim works diﬀ erently than the Assist rim. When using these rims the motor will give continuous support. As long as the Drive rim is pushed forward, the wheelchair will move forward. If the Drive rim is pushed backwards, the wheelchair will move backwards. When the Drive rim is released, the motor support will stop. The wheelchair will not immediately stop, but gradually brake on the motor. If the system is turned oﬀ , the Drive rims have no function.

Drive rim usage

The Drive rim can be pushed forward and backwards until an end position; in this position the speed is maximum. If the Drive

rim is carefully pushed forward, the speed increases according to how far the rim is pushed forward.

Braking with the Drive rim

By pushing the rim carefully backwards, the speed decreases. This way you can brake with the Drive rim. By moving the rim even more backwards, the wheelchair will drive backwards. The acceleration and maximum speed diﬀ ers per driving proﬁ le.

Warning!

While using the Drive rim, beware not to put your ﬁ ngers too far inwards between the spokes of the wheel. If you do not feel secure, it is advised to use power assist spoke protection.

Before driving, be sure the tyres are suﬃ ciently inﬂ ated (up to 6-10 bar).

Before driving, be sure the batteries are suﬃ ciently charged.

Always use the Drive rims in a smooth and uniform way to get the best driving experience.

4.5 Obstacles and slopes

Take extra care when taking obstacles (such as thresholds, curbs and narrow doors and hallways) and when driving on slopes. Only use the power assist in situations where you would feel safe with a normal manual wheelchair without Power assist.

Always use the Assist rim for taking obstacles and slopes. This way you have the best control for driving and braking. Use the Drive rim for equal level driving

Taking obstacles

The power assist is certiﬁ ed for taking obstacles up to 50 mm. High obstacles can best be taken by backward driving. Low obstacles can be taken by forward driving. The size and construction of the front wheels of your wheelchair are of great inﬂ uence on taking obstacles. Drive carefully towards the obstacle with the front wheels. Select the appropriate proﬁ le and then take a short run up (15-20 cm) to climb the obstacle. Make sure the wheelchair does not keep accelerating after climbing an obstacle.

Warning!

Do not drive oﬀ /over of high obstacles (higher than 50 mm).

Driving up a curb

1. Choose the place where the curb is at its lowest.

2. Drive straight up to the curb at a right angle to it (15-20 cm in front of the curb).

3. Propel the Assist rim forward. Drive up the curb without changing direction.

4. Maintain speed until all of the wheels are on the sidewalk. If mounting the sidewalk is not possible, ﬁ nd a place where the curb is lower.

Driving down a curb

1. Choose the place where the curb is at its lowest.

2. Drive straight down the curb with your front wheels at a right angle to it.

18 WheelDrive

3. Propel the Assist rim slowly forward. Drive down the curb carefully and as slowly as possible without changing direction.

Pushing the wheelchair to take an obstacle

An obstacle can be taken by an attendant pushing the wheelchair. Put the power assist oﬀ before pushing.

Driving on slopes

Warning!

When driving up or down a slope always use an anti-tip device.

Only drive up/down a slope using the Assist rims, since you have direct control for driving and braking. Never use the Drive rims in this case.

Avoid sudden, jerky movements; always drive carefully and with the highest concentration.

Avoid making emergency stops on a slope.

For your safety: avoid changing direction on a slope whenever possible.

Do not drive on slopes with loose gravel or a sandy surface, as one of the driving wheels could slip/spin.

If you notice a signiﬁ cant decrease in speed when driving up a slope, try to take a route which is less steep.

Take special care when driving down slopes of any kind. Adjust your speed to maintain safe control.

When descending at a high speed, the power assist can switch into the free running mode due to over-voltage. The wheels continue to run, but power assistance is not available anymore.

Do not drive on slopes for extended periods of time in order to prevent the motor from overheating.

19WheelDrive

4.6 Mounting and dismounting a

power assist

power assist is designed to ﬁ t most common manual wheelchair frames and can be installed without making adjustments to the wheelchair frame itself. The power assist wheels can be taken oﬀ for transport or changing them for manual wheels. The power assist is mounted on a wheelchair frame by making use of a quick release axle. The size and setting of the quick release axle is dependent on the brand and type of your manual wheelchair frame and determined by your dealer.

At the rear side of a power assist wheel there is an anti-tip plate in which 2 cone-shaped supports are screwed (ﬁ gure 11). The position of the supports is dependent on the brand and type of your manual wheelchair frame and determined by your dealer.

Dismounting of a wheel (ﬁ gure 12) By rotating the wheel handle upwards, the wheel handle will be placed in the correct position. Unlock the axle by pushing the unlock button just above the handle with your thumb. Now the wheel can be removed from the chair. The easiest way to do this is by lifting the chair a little bit.

1. Pull the wheel handle vertically up.

2. Push the button to release the quick release axle.

3. Pull the wheel handle to dismount the wheel.

20 WheelDrive

Warning!

Due to the weight the power assist wheel might require eﬀ ort to mount. If you do not feel secure mounting the wheel, due to the weight of the wheel, ask an attendant to mount the wheel.

Never pull at the Drive rim to take oﬀ the wheel. (ﬁ gure 13 and 14)

Never use the Drive rim for carrying the power assist in any way – this can damage the Drive rim.

Do not use the Drive rim, but only the tire or the Assist rim for mounting and dismounting a wheel.

The power assist wheels must never be removed, when a person is sitting in the wheelchair.

Mounting a wheel (ﬁ gure 15) To mount a wheel, the wheel handle has to be pulled upwards, in the open position.

1. Position the axle in the hole of the adapter sleeve on your wheelchair, and unlock the axle by pushing the unlock button just above the handle with your thumb, and release the button again. The cone-shaped supports will guide the wheel into the right position. Check if the wheels cannot be pushed further into the bus on your wheelchair, then check by pulling at the handle without pushing the unlock button that you cannot pull back the wheel anymore.

2. Push the wheel handle down vertically.

3. Then turn the handle downwards.

21WheelDrive

See the sticker to close the wheel handle (ﬁ gure 16)

Warning!

During the mounting process always check that the wheel cannot be pulled out anymore.

Using the power assist is only permitted with the power assist correctly placed and locked.

Place the power assist wheels according to the identiﬁ cation on the left or right side respectively (ﬁ gure 17 and 18).

Caution!

Make sure the wheel handle is fully closed, level with the battery pack. If the wheel handle is not completely closed the power assist cannot be switched on.

4.7 Storage

When the power assist is not in use, it must be stored in a dry place where it will not be exposed to weather conditions.

Note!

During storage, the ambient temperature should not be lower than -20°C or higher than +40°C (+40°C is the maximum allowed temperature for the used batteries).

Caution!

When not using the batteries: It must be avoided that the batteries will get discharged deeply – deep discharge will damage the batteries. Therefore charge the batteries every 3 months to their full capacity.

22 WheelDrive

4.8 Lifting the power assist

wheels

Caution!

In order to mount or lift the power assist wheels, only hold them at the tyre or Assist rim (ﬁ gure 19). Never use the Drive rim, the wheel handle or battery pack handle for lifting the wheel (ﬁ gure 20 and 21). This may cause severe damage to the sensor system.

Warning!

If you do not feel secure lifting the power assist wheel due to the weight of it, ask an attendant to lift the wheel.

4.9 Safety functionalities

For your safety, several safety functionalities are implemented in the system. Most of them will not be noticed, but some can become obvious in case of unintended use. These intentional functionalities are described here.

1. When the wheel handle is in open position, no support is possible. The system will detect this situation and will switch oﬀ the power.

2. A continuous Power assist request during about ¾ wheel rotation will disable the Power assist functionality (e.g. when the Assist rim is blocked). Pushing one of the proﬁ le buttons will enable the function again.

3. Support is only available up to 6 km/h. If the speed exceeds approximately 10 km/h, the power assist will enable the ‘braking on the motor’ feature to limit the speed increase; In the most unlikely situation of generation exceeding high voltage limits (>38V) the free running mode will be activated.

4. If during the activation of the system the Drive and/or Assist rim has a displacement from the initial rest position, one or both of the rims must be placed to the initial rest position ﬁ rst, before the function can be used.

5. In case you are charging the main batteries the motor is disabled.

23WheelDrive

6. To save energy and to avoid possible unintended activations, the power will be switched oﬀ automatically after approximately 15 minutes of not using the power assist.

24 WheelDrive

5 Anti-tip settings

For your own safety the power assist is equipped with a so-called anti-tip device. This will prevent you from tipping-over backwards.

Warning!

Always use the anti-tip device in its protective position when driving with the power assist.

For transportation or driving down a curb you can temporarily rotate the anti-tips in an upwards position. This can be done by pulling the anti-tip backwards, and rotating it upwards (ﬁ gure 22)

By again pulling the anti-tip backwards, and rotating it downwards, the anti-tip can be set back to its protective (safe!) position (ﬁ gure 23).

Warning!

The anti-tip device is important for your safety and prevent you from tipping backwards in case of a high acceleration. If the anti-tip blocks other parts of your own wheelchair please contact your dealer

25WheelDrive

6 Transport

6.1 Transport of wheelchair ﬁ tted

with power assist

Observe the following if you want to transport a wheelchair with power assist.

Warning!

Please check the manual of your wheelchair for proper instructions on transportation.

The combination of a wheelchair and Wheeldrive has not been tested for use as a seat in a motor vehicle during transport. We therefore recommend using a regular car seat during vehicle transportation.

Never use the Drive rim for carrying the power assist in any way – this can damage the Drive rim

The power assist must always be switched oﬀ when being transported.

The battery pack of the power assist can be removed when transporting the system and storing securely.

In case the power assist is transported unattached from a wheelchair, the wheels must be secured against moving during transport to avoid any danger for the occupants, and to avoid any damage to the power assist.

Caution!

When transporting the wheels without battery, make sure to securely pack the wheels and protect the battery connector points against damage (see ﬁ gure 24).

26 WheelDrive

6.2 Special shipping requirements

A wheelchair with power assist may be transported by road, rail, sea or air and the batteries conform to IATA regulations.

Caution!

Before you travel, please contact the appropriate carrier. The travel operator will be able to supply details of any special requirements/instructions.

A certiﬁ cate of conformity IATA 2.3.2.2 has been drawn to inform the operator about the type of battery in your power assist. Download the certiﬁ cate on www. SunriseMedical.eu or request a copy from your retailer. The battery type is also mentioned in chapter 9 Technical speciﬁ cations.

For information about dimensions and weight of the power assist please refer to chapter 9 Technical speciﬁ cations.

Ensure that any detachable parts are secured with your mobility aid or separately packed and labelled so they do not get lost during loading and unloading.

We recommend to check in the batteries individually packed and duly protected against damage and short circuiting. Clearly mention 'non-spillable battery' on the transport packaging. Do not travel with damaged or defect batteries.

Take this user manual with you. The carrier will need to refer to the following sections:

• 6.1 Transport without occupant.

• Remove / placing the battery pack (see

4.3 Using the batteries)

• 4.6 Mounting and dismounting a power assist

7 Maintenance

Note!

The power assist should be serviced by your dealer once a year or, in the case of intensive use, every six months.

All required maintenance that must be performed by the user is described in this section.

Repairs must be carried out by an authorized person; please contact your dealer if a repair is needed.

7.1 Maintenance plan

The lifespan of the power assist is very dependent on its usage and maintenance.

• Charge the batteries daily

• Ensure that the batteries are always fully charged. Not using the batteries for an extended period of time can damage them. Do not use the power assist if the batteries are almost run down and never if the batteries are completely empty. This can seriously damage the batteries and you may run the risk of coming to an unintended standstill.

• If the capacity of the batteries is continually decreasing so that the wheelchair can only be used for short trips, this means that the batteries are reaching the end of their lifespan. The batteries then need to be replaced.

• Periodically check for low-bat warning of the sensor box (see paragraph 7.1). Preventively we advice to re-new the AA batteries every 6 months.

Warning!

Batteries contain acids. Damaged batteries are a serious health hazard.

28 WheelDrive

Replacing the sensor box AA batteries (ﬁ gure 26)

Both battery compartments of the sensor box can be opened with a PH1 (Philips) screwdriver (2 screws per compartment) (ﬁ gure 27 and 28) .

Caution!

Always replace both AA batteries at the same time.

The polarity is clearly indicated in the battery compartment – incorrect polarity can damage the electronics.

Note!

Periodically check for low-bat warning of the sensor box (see paragraph 7.1). Preventively we advice to re-new the AA batteries every 6 months. Only use non-rechargeable high quality batteries.

7.2 Tyres

Check the tyre pressure at least weekly (and inﬂ ate the tyres if necessary); air pressure must be between 6-10 bar. Tyres that are not inﬂ ated to the appropriate level will have a negative eﬀ ect on the performance of the power assist. Moving the wheelchair will require more energy then, making more demands on the batteries. Furthermore, wear on the tyres when driving with soft tyres is unnecessarily high.

Caution!

Never exceed the maximum tyre pressure.

Tyres should only be replaced by a qualiﬁ ed specialist – please contact your dealer.

In case of a ﬂ at tire while using the power assist make sure to drive slowly, and try to inﬂ ate the tyres again, or let the tires be repaired by a qualiﬁ ed specialist as soon as possible. Using the power assist with ﬂ at tires can damage the tyres and rims.

7.3 Cleaning

Clean the power assist with a wet towel and a non aggressive detergent monthly. First, wipe the dirty parts clean using a wet sponge. Preferably use clean water or a mild soap solution. Wipe the parts dry using a soft dry cloth.

Caution!

Ensure that the controller is switched oﬀ while cleaning. If one of the rims is accidently touched, the wheelchair can start to move. Take care with water since you deal with an electronic system.

Never use abrasive or aggressive cleaning agents. These can scratch the wheelchair. Do not use organic solvents such as thinner, petrol or white spirit.

7.4 Decommissioning the power

assist

If your power assist has become redundant or needs to be replaced, it can usually be taken back by your dealer. If this is not possible, please ask your local authority about the possibilities for recycling or environmentally friendly disposal of the materials.

Various diﬀ erent plastics and metals were used in the manufacture of the power assist. Furthermore, the power assist contains electronic components that should be disposed of as electronic waste. The batteries should be disposed of as chemical waste.

8 Troubleshooting

If the power assist is not working as you would expect, please check the following points:

1. Check section paragraph 4.9 Safety functionalities.

2. Turn the wheelchair oﬀ and then back on again.

3. Check if the wheel handle is closed.

4. Check if the Assist rim and Drive rim are at their rest position at power on.

5. Check whether the batteries are charged. Recharge them if needed.

6. Check if the sensor box AA batteries have suﬃ cient capacity. During the ﬁ rst use of the Assist rim after starting up a system notiﬁ cation will be given see paragraph 7.1. Replace the AA batteries if needed.

If, after taking all of the above steps, a problem still persists, contact your dealer.
