1.3 Type classification and permissible use

This vehicle was designed for persons whose ability to walk is impaired, but who are still in terms of
their eyesight and physically and mentally able to operate an electric vehicle. It has been classified
according to EN 12184 as a class B mobility product (for indoor and outdoor areas). It is
therefore compact and agile enough for indoor areas, but also able to overcome many obstacles in
outdoor areas.

You can find precise information about speed, turning radius, driving range, maximum safe slope,
maximum obstacle height and permissible operating conditions in chapter "Technical
specifications" starting from page 125.

Please also pay attention to all safety information in chapter "Safety notes" starting from page 19.

The vehicle was successfully tested according to German and international standards as to its
safety. It satisfies the requirements according to DIN EN 12184 including EN 1021-1/-2. It was also
tested successfully according to EN60529 IPX4 as to its resistance to spray water, and is therefore
well suited for typical middle European weather conditions. When equipped with an appropriate
lighting system, the vehicle is suitable for use on public roads.

1.4 Indications

The use of this mobility product is recommended for the following indications:

17

The inability or a greatly restricted ability to walk within the scope of the basic requirement to be
able to move within one’s own four walls. The need to leave the dwelling place in order to get some
fresh air during a short walk or to reach those places generally to be found at close distance to the
dwelling and where everyday business is carried out.

Provision of power wheelchairs for interior and exterior areas is advisable if the use of hand­operated wheelchairs is no longer possible on account of the disability, yet proper operation of an
electromotive drive unit is still practicable.

1.5 Usability

Only use a power wheelchair when it is in perfect working order. Otherwise, you might put yourself
and others at risk.

The following list does not claim to be exhaustive. It is only intended to show some of the situations
that could affect the usability of your power wheelchair.

In certain situations, you should immediately stop using your wheelchair. Other situations allow you
to use the wheelchair to get to your dealer.

• You should immediately stop using your power wheelchair if its usability is restricted due to:

- brake failure

• You should immediately contact an authorised Invacare® dealer if the usability of your power
wheelchair is restricted due to:

- the lighting system failing or being defective

- reflectors falling off

2 Safety notes

READ WELL BEFORE OPERATION!

2.1 General safety notes

Danger of injury if mobility device is used in any other way than the purpose described in
this manual!

• Only ever use the mobility device in accordance with the instructions in this User's Manual

(see chapter "Type classification and permissible use" on page 16).

• Pay strict attention to the safety information.

Danger of injury if the mobility device is driven when ability to operate a vehicle is
impaired by medication or alcohol!

• Never drive the mobility device under the influence of medication or alcohol. If necessary, the

mobility device must be operated by an attendant who is physically and mentally able.

Danger of damage or injury if mobility device is accidentally set into motion!

• Switch the mobility device off before you get in, get out or handle unwieldy objects.

• When the drive is disengaged, the brake inside the drive is deactivated. For this reason,

pushing the mobility device by an attendant is only recommended on flat surfaces, never on
gradients. Never leave your mobility device on a gradient with its motors disengaged. Always
re-engage the motors immediately after pushing the mobility device (see chapter "Pushing the
wheelchair in freewheel mode" on page 35).

20

Danger of injury if the mobility device is switched off while driving, for example by
pressing the On/Off Button or disconnecting a cable, due to it coming to an abrupt, sharp
stop!

• If you have to brake in an emergency, simply release the joystick which will bring you to a halt.

(refer to the joystick operating manual for more information).

Danger of injury when transferring mobility device to a vehicle for transport with the
occupant seated in it!

• It is always better to transfer the mobility device to a vehicle without the occupant seated in it.

• If the mobility device needs to be loaded up a ramp together with its driver, ensure that the

ramp does not exceed the maximum safe slope (see chapter "Technical specifications" from
page 125).

• If the mobility device does need to be loaded using a ramp which exceeds the maximum safe

slope (see chapter "Technical specifications" from page 125), then you must use a winch. An
attendant can safely monitor and assist the loading process.

• As an alternative you can use a platform lift. Ensure that the total weight of the mobility device

including the user does not exceed the maximum permissible weight for the platform lift or
winch if you are using.

Danger of injury if maximum permissible load is exceeded!

• Do not exceed the maximum permissible load (see chapter "Technical specifications" from

page 125).

• The mobility device is only designed for use by a single occupant whose maximum weight

does not exceed the maximum permissible load of the device. Never use the mobility device to
transport more than one person.

21

Danger of injury due to wrong lifting or dropping of heavy components!

• When maintaining, servicing or lifting any part of your mobility device, take into account the

weight of the individual components especially the batteries. Be sure at all times to adopt the
correct lifting posture and ask for assistance if necessary.

Danger of falling out of the mobility device.

• Do not slide forward on the seat, do not lean forward between your knees, do not lean

backwards out over the top of the backrest, for example to reach an object.

• If a posture belt is installed, it should be correctly adjusted and used each time you use the

mobility device.

• When transferring to a different seat, position the mobility device as close as possible to the

new seat.

Danger of injury by moving parts!

• Make sure that no injury is incurred by moving parts of the mobility device, like wheels or one

of the Lifter Modules (if fitted), especially when children are around.

Risk of injury from hot surfaces!

• Do not leave the wheelchair in direct sunlight for prolonged periods. Metal parts and surfaces

such as the seat and armrests can become very hot.

Danger of fire or breaking down due to electric devices being connected!

• Do not connect any electric devices to your mobility device that are not expressly certified by

Invacare® for this purpose. Have all electrical installations done by your authorised Invacare®
Dealer.

22

2.2 Safety information with regard to care and maintenance

Danger of accident and loss of guarantee if maintenance is insufficient!

• For reasons of safety and in order to avoid accidents which result from unnoticed wear, it is

important that this electric mobility product undergoes an inspection once every year under
normal operating conditions (see inspection plan contained in service instructions).

• Under difficult operating conditions such as daily travel on steep slopes, or in the case of use

in medical care cases with frequently changing wheelchair users, it would be expedient to
carry out intermediate checks on the brakes, accessories and running gear.

• If the mobility product is to be operated on public roads, the vehicle driver is responsible for

ensuring that it is in an operationally reliable condition. Inadequate or neglected care and
maintenance of the mobility product will result in a limitation of the manufacturer's liability.

23

2.3 Safety information on electromagnetic interference

This electric vehicle was successfully tested in accordance with International standards as to its
compliance with Electromagnetic Interference (EMI) regulations. However, electromagnetic fields,
such as those generated by radio and television transmitters, and cellular phones can influence the
functions of electric vehicles. Also, the electronics used in our vehicles can generate a low level of
electromagnetic interference, which however will remain within the tolerance permitted by law. For
these reasons we ask you to please observe the following precautions:

WARNING: Danger of malfunction due to electromagnetic interference!

• Do not switch on or operate portable transceivers or communication devices (such as radio

transceivers or cellular phones) when the vehicle is switched on.

• Avoid getting near strong radio and television transmitters.

• In case the vehicle should be set in motion unintentionally or the brakes are released, switch

it off immediately.

• Adding electrical accessories and other components or modifying the vehicle in any way can

make it susceptible to electromagnetic interference. Keep in mind that there is no sure way to
determine the effect such modifications will have on the overall immunity of the electronic
system.

• Report all occurrences of unintentional movement of the vehicle, or release of the electric

brakes to the manufacturer.

24

2.4 Safety information on driving and freewheel mode

Danger of injury if the wheelchair tips over!

• Inclines and declines can only be travelled up to the maximum safe slope (see chapter

"Technical specifications" from page 125).

• Always return the backrest of your seat or the seat tilt to an upright position before ascending

slopes. We recommend that you position the seat backrest and the seat tilt (if fitted) slightly to
the rear before descending slopes.

• Only ever drive downhill at a maximum of 2/3 of the top speed. Avoid abrupt braking or

accelerating on gradients.

• If at all possible, avoid driving on slippery surfaces (such as snow, gravel, ice etc.) where there

is a danger of you losing control over the vehicle, especially on a gradient. If driving on such a
surface is inevitable, then always drive slowly and with the utmost caution.

• Never attempt to overcome an obstacle when on an uphill or downhill gradient.

• Never attempt to drive up or down a flight of steps with your wheelchair.

• When overcoming obstacles, always observe the maximum obstacle height (see chapter

"Technical specifications" from page 125 and information about overcoming obstacles in
chapter "Taking Obstacles" from page 32).

• Avoid shifting your centre of gravity as well as abrupt joystick movements and changes of

direction when the wheelchair is in motion.

• Never use the wheelchair to transport more than one person.

• Do not exceed the overall maximum permissible load or the maximum load per axle (see

chapter "Technical specifications" on page 125).

• Note that the wheelchair will brake or accelerate if you change the Driving Mode whilst the

wheelchair is in motion.

25

Danger of breaking down in adverse weather conditions, i.e. extreme cold, in an isolated
area!

• If you are a user with severely limited mobility, we advise that in the case of adverse weather

conditions DO NOT attempt a journey without an accompanying attendant!

Danger of injury if your foot slides off the footrest and gets caught underneath the
wheelchair when it is in motion!

• Make sure each time before you drive the wheelchair that your feet are squarely and securely

in place on the footplates, and that both legrests are properly locked into place.

Danger of injury if you collide with an obstacle when driving through narrow passages
such as doorways and entrances!

• Drive through narrow passages in the lowest driving mode and with due caution.

If your power wheelchair has been fitted with angle-adjustable legrests, there is a danger
of personal injury and damage to the wheelchair if you drive the wheelchair with the
legrests raised!

• To avoid unwanted displacement of the wheelchair centre of gravity to the front (especially

when travelling downhill) and in order to avoid damage to the wheelchair, angle-adjustable
legrests must always be lowered during normal travelling.

CAUTION: Danger of tipping! Anti tip wheels (stabilisers) are only effective on firm
ground! They sink in on soft ground such as grass, snow or mud if the mobility device
rests itself on them. They lose their effect and the mobility device can tip over.

• Only drive with extreme care on soft ground, especially during uphill and downhill journeys. In

31

5 Driving

NOTE

The maximum load capacity that is stated in the technical data only states that the system is
designed for this mass in total. However, this does not mean that one can sit a person with this
body weight in the wheelchair without restrictions. Attention must be paid to the body
proportions, such as height, weight distribution, abdominal girth, leg and calf girth and seat
depth. These factors have a strong influence on driving features such as tilt stability and traction.
The permissible axle loads in particular must be adhered to (see chapter "Technical
specifications" as from page 125)! It may possibly be necessary to carry out adaptations to the
seat system.

5.1 Before driving for the first time...

Before you take your first trip, you should familiarise yourself well with the operation of the vehicle
and with all operating elements. Take your time to test all functions and driving modes.

NOTE:

If installed, make sure to properly adjust and use the postural belt each time you use the
wheelchair.

Sitting Comfortably = Driving Safely
Before each trip, make sure that:

• You are within easy reach of all operating controls.

• The battery charge is sufficient for the distance intended to be covered.

• The postural belt (if installed) is in perfect order.

32

• The rear mirror (if installed) is adjusted so you can look behind at all times without

having to bend forward or shift your seating position.

5.2 Taking Obstacles

5.2.1 Maximum obstacle height

You can find information about maximum obstacle heights in the chapter entitled "Technical
specifications" from page 125.

5.2.2 Safety information when ascending obstacles

CAUTION: Danger of Tipping Over!

• Never approach obstacles at an angle but at 90 degrees as shown below.

• Put your backrest into an upright position before climbing an obstacle.

ATTENTION: Risk of falling out of the chair and damage to the power wheelchair such as
broken castors!

• Never approach obstacles that are higher than the maximum climbable obstacle height. For
the maximum climbable obstacle height, see "Technical specifications" on page 125.

• If unsure whether the kerb climb is possible or not, move away from the obstacle and if
possible find another location.

33

5.2.3 The correct way to overcome obstacles

Ascending

• Approach the obstacle or the kerb slowly, head-on and at a right angle.

• Depending on the wheel drive type, stop in one of the following positions:

- In the case of centrally driven wheelchairs: 5 - 10 cm before the obstacle.

- For all other drives: approx. 30 - 50 cm in front of the obstacle.

• Check the position of the front wheels. They must be in driving direction
and at right angles to the obstacle.

• Approach slowly and keep at a consistent speed until the rear wheels
have also passed over the obstacle.

Right

Wrong

Descending

The approach to descend an obstacle is the same as to ascend it with the
difference that you need not stop before descending.

• Descend the obstacle very slowly.

34

5.3 Driving up and down gradients

For information concerning the maximum safe slope, please see chapter "Technical
specifications" starting on page 125.

WARNING: Danger of tipping over!

• Only ever drive downhill at a maximum of 2/3 of the top speed. Avoid sudden changes of
direction or abrupt braking when driving on slopes.

• Always return the backrest of your seat or the seat tilt (if adjustable seat tilt is available) to an
upright position before ascending slopes. We recommend that you position the seat backrest
or the seat tilt slightly to the rear before descending slopes.

• Always lower the lifter (if fitted) to its lowest position before ascending or descending a slope.

• Never attempt to ascend or descend a slope on slippery surfaces or where there is a danger

of skidding (such as wet pavement, ice etc).

• Avoid trying to get out of the vehicle on an incline or a gradient.

• Always drive straight in the direction the road or path you are on goes, rather than attempting

to zigzag.

• Never attempt to turn around on an incline or a slope.

5.4 Parking and stationary

When parking your vehicle or if your vehicle is stationary for a prolonged period:

• Switch the vehicle's power system off (ON-/OFF key).

• Activate your anti-theft lock, if existing.

35

5.5 Use on public roads

If you wish to use your wheelchair on public roads and lighting is required by national legislation,
then your wheelchair needs to be equipped with an appropriate lighting system.

Please contact your Invacare ® dealer if you have any questions.

6 Pushing the wheelchair in freewheel mode

The motors of the wheelchair are equipped with automatic brakes, preventing that the wheelchair
starts rolling out of control when the joystick box is switched off. When pushing the wheelchair
manually whilst freewheeling, the magnetic brakes must be disengaged.

6.1 Disengaging Motors

Danger of the vehicle running away!

• When the motors are disengaged (for push operation whilst freewheeling), the
electromagnetic motor brakes are deactivated! When the vehicle is parked, the levers for
engaging and disengaging the motors must without fail be locked firmly into the "DRIVE"
position (electromagnetic motor brakes activated)!

NOTE:
The wheelchair disengaging mechanism is fitted with a gas pressure spring which prevents
overloading the disengager. When the drive wheels are under torque load - for example if the
wheelchair is on an incline - the gas pressure spring is activated. When the engaging lever is
pressed forwards it does not remain in the "Pushed" position, but moves automatically back to
the "Drive" position. To disengage the drive, the drive wheels must be unloaded by moving the
wheelchair slightly forwards and backwards again.

36

NOTE:

The motors may only be disengaged by an attendant, not by the user!
This ensures that the motors are only disengaged if an attendant is available to secure the

wheelchair and prevent unintended rolling.

The lever for disengaging the motors is on the rear right side on the wheelchair chassis.

Disengaging motors:

• Switch off remote.

• Withdraw the locking pin (1). Push the engaging

lever (2) forwards. If necessary, move the
wheelchair slightly forwards and backwards during
disengaging. The motors are now disengaged.

Re-engaging motors

• Pull the engaging lever (2) to the rear. The motors
are now re-engaged.

7 Remotes

Your wheelchair may be equipped with one of several different remotes. For information on the
different functions and how to operate a particular remote, please see its corresponding User
Manual (enclosed).

37

8 Adjusting the wheelchair to the user's seating posture

CAUTION: Damage to wheelchair and accident hazard! It is possible that collisions can
occur between wheelchair components due to various combinations of adjustment
options and their individual settings!

• The wheelchair is fitted with an individual, multiply adjustable seating system including
adjustable legrests, armrests, a headrest or other options. These adjustment options are
described in the following chapters. They are used to adapt the seat to the physical
requirements and the condition of the user. When adapting the seating system and the seat
functions to the user, ensure that no wheelchair components collide.

Note

Initial setup should always be done by a healthcare professional. Adjustment by the user is only
recommended after they have been given appropriate guidance by the healthcare professional.

8.2 Adjusting the seat angle / seat height

8.2.1 Manual adjustment using perforated plates

There are three perforated plates underneath the seat for adjusting the seat angle and the seat
height. These perforated plates in connection with the adjustable rear holding plates result in a
multitude of different setting possibilities.

The adjustment range of the seat height is 42.5 cm to 50 cm. The adjustment range of the seat
angle is 22°. Please note: The higher the seat setting, the smaller the adjustment range of the seat
angle!

Requirements:

• Allen key 5 mm

• Allen key 6 mm

• Jaw spanner 13 mm

• Torque wrench

• Loctite medium-hard

44

• The picture on the right shows the position of
the perforated plates (1) and the fastening
screws on the holding plates (2) for adjusting
seat height and seat angle.

The picture on the right shows the front perforated
plates. The approach is similar for the rear
perforated plates. To adjust the front perforated
plates a 13 mm open-ended spanner is required
in addition to the 5 mm Allen key.

• To adjust seat height/seat angle loosen the
screw using the spanner and remove.

• Set the perforated plates to the desired
height/angle.

• Apply Loctite to the screw, re-insert the screw
and tighten to 40 Nm using the spanner.

45

Seat height and angle can be adjusted additionally via
the rear holding plates.

• Loosen the rear fastening screw on one side (in
bushing 1) so that the holding plate can be
swivelled up or down.

• Loosen the front fastening screw and remove
(depending on the position the screw is either in
bushing 2 or 3).

• Repeat the procedure on the other side.

• Low setting = Hole combination 1 and 2.

• High setting = Hole combination 1 and 3.

• Apply the Loctite to the screw, reposition the

screws and tighten to 25 Nm +/- 3 Nm.

46

The swivelling rear perforated plates have five
positions. These are marked on the illustration on the
right by the letters A to E.

If the holding plates are in the low position (see
above), all five positions can be used. In the high
position only positions B, C, D and E are possible! In
position A there is a collision between the holding plate
and the seat frame.

This results in the following seat heights:

Holding plate in the low position:

Position of the perforated plate / seat height:

• A / 42.5 cm

• B / 44 cm

• C / 44 cm

• D / 45 cm

• E / 45.5 cm

Holding plate in the high position:

Position of the perforated plate / seat height:

• B / 49 cm (at 6° seat tilt)

• C / 47 cm

• D / 48 cm

• E / 50 cm

47

8.2.2 Electric adjustment in the front / perforated plate in the rear

Please consult the user manual for your remote for information about electrical adjustment.

In addition to the electric actuator under the seat in the front, the Dragon with electric seat tilt also
has two manual adjustment plates in the rear. When combined, the electric seat tilt in the front and
the manual adjustment in the rear provide a wide range of possible settings.

The total seat tilt adjustment range is from -4,5° to +25,5°. The ability to set a negative can be very
useful as an aid in getting out of the wheelchair.

Requirements:

• Allen key 5 mm

• Open-end spanner 13 mm

• Torque spanner

• The picture at right shows the position of the

perforated adjustment plates (1) and of the
electric actuator (2) that allow adjustment of
seat height and seat tilt.

48

• To adjust the seat height / seat tilt, use the
Allen key 5 mm and the open-end spanner 13
mm to loosen and remove the bolt (1).

• Adjust the perforated plate to the desired
height/angle.

• Re-position the bolt and tighten to 40 Nm
using the torque spanner.

On the Dragon with purely manual seat
height and tilt adjustment, the rear
fixation plates can be adjusted to two
different positions, high and low.

The Dragon with electric adjustment
only allows for the low position! If the
fixation plates are set to the high
position, then the electric seat tilt
actuator will collide with the frame of
the wheelchair!

49

The adjustable perforated plates in the rear can be set
to five different positions. These are shown in
illustration at right, and are designated with the letters
A to E.

The following seat heights and seat tilt adjustment ranges are possible:

8.6 Postural belts

A postural belt is an option which can either be fixed to the wheelchair ex-works or can be
retrofitted by your specialist dealer. If your wheelchair is fitted with a postural belt, your specialist
dealer will have informed you about fitting and usage.

The postural belt is used to help the wheelchair user keep an optimum sitting position. Correct use
of the belt assists the user in sitting securely, comfortably and well-positioned in the wheelchair,
especially for such users who do not have such a good sense of balance while sitting.

NOTE:
We recommend using the postural belt whenever the wheelchair is used. The belt should be tight
enough to ensure that you are sitting comfortably and that your body is in the correct sitting
position.

8.6.1 Types of postural belts

Your wheelchair can be fitted with the following postural belt types ex-works. If your wheelchair has
been fitted with a different belt to those listed below, please ensure that you have received the
manufacturer's documentation with regard to correct fitting and use.

Belt with metal buckle, adjustable one side

Belt can only be adjusted on one side which can result in
the buckle not sitting centrally.

87

Belt with metal buckle, adjustable both sides

Belt can be adjusted on both sides. This means that the
buckle can be centrally positioned.

Belt with Velcro fastening

Adjustments are made using the Velcro fastening. For this
reason no buckle is required on this belt.

88

Harness with metal buckle, adjustable
on both sides

Harness can be adjusted on both sides.
This ensures that the buckle is always
centrally positioned.

89

8.6.2 Adjusting the postural belt correctly

• Ensure that you are sitting correctly, which means that you are sitting right at the back of the
seat, your pelvis is positioned erect and as symmetrically as possible, not to the front, to the
side or at one edge of the seat.

• Position the postural belt so that your hipbones can be easily felt above the belt.

• Adjust the belt length using one of the adjustment aids described above. The belt should be

adjusted so that you can fit a flat hand between the belt and your body.

• The buckle should be positioned as centrally as possible. In doing so, please carry out
adjustments on both sides as much as possible.

• Please check your belt every week to ensure that it is still in good working condition; to ensure
it has no damage or wear, and that it is fixed properly to the wheelchair. If the belt is only
fastened with a bolted connection, ensure that the connection has not loosened or undone.
You can find more information about maintenance work on belts in the service manual, which is

9 Electrical system

9.1 Electronics protection system

The vehicle drive electronics is fitted with an overload protection.

If the drive is severely overloaded over a long period (e.g. during steep climbs) and, above all, at
simultaneous high external temperatures, the electronic system can overheat. In this case, the
vehicle performance is gradually reduced until it comes to a standstill. The status display shows a
corresponding blink code (please refer to the user manual for your remote). If you switch the drive
electronics off and then on again, the error message is deleted and the electronics can be switched
on again. It can however take up to five minutes until the electronics has cooled down enough for
the drives to apply their full performance.

If the drive is blocked due to an insurmountable obstacle, for example a kerb or similar which is too
high, and the driver attempts to run the drive for more than 20 seconds against this obstacle, the
electronic system switches the drives off to avoid damage. The status display shows a
corresponding flash code (please refer to the user manual for your remote). If you switch the drive
electronics off and then on again, the error message is deleted and the electronics can be switched
on again.

93

9.1.1 The main fuse

NOTE

A defective main fuse may be replaced only after checking the entire electric system. An
Invacare® specialised dealer must perform the replacement. You can find information on the
fuse type in chapter "Technical specifications" starting on page 125.

The entire electric system of the wheelchair is
protected by the main fuse against overloading.

The main fuse is to be found underneath the battery
cover (1).

9.2 Batteries

Power is supplied by two 12 V batteries. The batteries are maintenance-free and only need regular
charging.

In the following, you find information on how to charge, handle, transport, store, maintain, and use
batteries.

9.2.1 Charging the batteries

9.2.1.1 General information on charging

New batteries should always be fully charged once before their first use. New batteries will be at
their full capacity after having run through approx. 10 - 20 charging cycles (break-in period). This
break-in period is necessary to fully activate the battery for maximum performance and longevity.
Thus, range and running time of your mobility device could initially increase with use.

Gel/AGM lead acid batteries do not have a memory effect as NiCd batteries.

9.2.1.2 General instructions on charging

Follow the instructions listed below to ensure safe use and longevity of the batteries:

• Charge 12 hours prior to initial usage.

• We recommend charging the batteries daily after every discharge even after partly discharge,

as well as each night over night. Depending on the level of discharge, it can take up to 12
hours until the batteries are fully charged again.

• When the battery indicator reached the red LED range, charge the batteries for 16 hours
minimum, neglecting the charge complete display!

• Try to provide a 24 hour charge once a week to make sure that both batteries are fully charged.

95

• Do not cycle your batteries at a low state of charge without regularly recharging them fully.

• Do not charge your batteries under extreme temperatures. High temperatures above 30 °C are

not recommended for charging as well as low temperatures below 10 °C.

• Use only charging devices in Class 2. This class of chargers may be left unattended during
charging. All charging devices which are supplied by Invacare® comply with these
requirements.

• You cannot overcharge the batteries when using the charger supplied with your vehicle, or a
charger that has been approved by Invacare®.

• Protect your charger from sources of heat such as heaters and direct sunlight. If the battery
charger overheats, charging current will be reduced and the charging process delayed.

9.2.1.3 How to charge the batteries

Please see the instruction manuals for your remote and battery charger for the position of the
charging socket and further information about charging the batteries.

96

WARNING!
Risk of explosion and destruction of batteries if the wrong battery charger is used!

• Only ever use the battery charger supplied with your vehicle, or a charger that has been
approved by Invacare®.

Risk of electric shock and damage to the battery charger if it gets wet!

• Protect the battery charger from water.

• Always charge in a dry environment.

Risk of short circuit and electric shock if the battery charger has been damaged!

• Do not use the battery charger if it has been dropped or damaged.

Risk of electric shock and damage to the batteries!

• NEVER attempt to recharge the batteries by attaching cables directly to the battery terminals.

Risk of fire and electric shock if a damaged extension cable is used!

• Only ever use an extension cable if it is absolutely necessary. In case you must use one,
make sure it is in good condition.

Risk of injury if using the wheelchair during charging!

• DO NOT attempt to recharge the batteries and operate the wheelchair at the same time.

• DO NOT sit in the wheelchair while charging the batteries.

• Switch off the mobility device.

• Connect the battery charger to the charger socket.

• Connect the battery charger to the power supply.

9.2.1.4 How to disconnect the batteries after charging

• Once charging is complete, first disconnect the battery charger from the power supply, then
disconnect the plug from the remote.

97

9.2.2 Storage and Maintenance

Follow the instructions listed below to ensure safe use and longevity of the batteries:

• Always store the batteries fully charged.

• Do not leave the batteries in a low state of charge for an extended length of time. Charge a

discharged battery as soon as possible.

• In case your mobility device is not used for a longer period of time (that is more than two
weeks), the batteries must be charged at least once a month to maintain a full charge and
always be charged before use.

• Avoid hot and cold extremes when storing. We recommend to store batteries at a temperature
of 15 °C.

• Gel and AGM batteries are maintenance-free. Any performance issues should be handled by a
properly trained mobility device technician.

9.2.3 Instructions on using the batteries

CAUTION! Risk of damaging the batteries.

• Avoid ultra-deep discharges and never drain your batteries completely.

• Pay attention to the Battery Charge Indicator! Charge the batteries when the Battery Charge

Indicator shows that battery charge is low.

How fast the batteries discharge depends on many circumstances, such as ambient
temperature, condition of the surface of the road, tyre pressure, weight of the driver, way of
driving and utilisation of lighting.

• Try to charge the batteries always before you reach the red LED range.

98

The last 3 LED (two red and one orange) mean a remaining capacity of about 15 %.

• Driving with blinking red LED’s means an extreme stress for the battery and should be avoided
under normal circumstances.

• When only one red LED is blinking, the Battery Safe feature is enabled. From this time, speed
and acceleration is reduced drastically. It will allow you to move the mobility device slowly out
of a dangerous situation before the electronic finally cuts off. This is deep discharging and
should be avoided.

• Be aware that for temperatures below 20 °C, the nominal battery capacity starts to decline. For
example, at -10 °C the capacity is reduced to about 50 % of the nominal battery capacity.

• To avoid damaging the batteries, never allow them to be fully discharged. Do not drive on
heavily discharged batteries if it is not absolutely necessary, as this will strain the batteries
unduly and shorten their life expectancy.

• The earlier you recharge the batteries, the longer they live.

• The depth of discharge affects the cycle life. The harder a battery has to work, the shorter is its

life expectancy.

Examples:

- One deep discharge stresses the same as 6 normal cycles (green /orange display off).

- The battery life is about 300 cycles at 80% discharge (first 7 LED off), or about 3000 cycles at
10% discharge (one LED off).

NOTE:

The number of LED can vary depending on the remote type.

99

• Under normal operation, once a month the battery should be discharged until all green and
orange LED are off. This should be done within one day. A 16 hour charge afterwards is
necessary as reconditioning.

9.2.4 Transporting batteries

The batteries supplied with your electric vehicle are not hazardous goods. This classification is
based on the German GGVS Hazardous Goods Road Transport Ordinances, and the IATA/DGR
Hazardous Goods Rail Transport / Air Transport Ordinances. Batteries may be transported without
restrictions, whether by road, rail or by air. Individual transport companies have, however,
guidelines which can possibly restrict or forbid certain transport procedures. Please ask the
transport company regarding each individual case.

9.2.5 Handling batteries

9.2.5.1 General instructions on handling the batteries

• Never mix and match different battery manufactures or technologies, or use batteries that do
not have similar date codes.

• Never mix gel with AGM batteries.

• Always have your batteries installed by a properly trained mobility device technician. They have

the necessary training and tools to do the job safely and correctly.

9.2.5.2 How to handle damaged batteries correctly

100
