Type classification and permissible use
This vehicle was designed for persons whose ability to walk is impaired, but who are still 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 exact information on speed, turning radius, range, safe climbing ability, maximum
obstacle height and permissible operating conditions in chapter "Technical Specifications"
starting from page 163.
Please also pay attention to all safety information in chapter "Safety Notes" starting from page 17.
The vehicle was successfully tested according to German and international standards as to its
safety. 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
Guarantee
The terms and conditions of the guarantee are part of the general terms and conditions particular to
the individual countries in which this product is sold.
15
1.5
Indications
The use of this mobility product is recommended for the following indications:
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 electric 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.
1.6
Life expectancy
We estimate a life expectancy of five years for this product, provided it is used in strict accordance
with the intended use as set out in this document and all maintenance and service requirements
are met. The estimated life expectancy can be exceeded if the product is carefully used and
properly maintained, and provided technical and scientific advances do not result in technical
limitations. The life expectancy can also be considerably reduced by extreme or incorrect usage.
The fact that we estimate a life expectancy for this product does not constitute an additional
warranty.

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 15).
• 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).
17
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 163).
• If the mobility device does need to be loaded using a ramp which exceeds the maximum safe
slope (see chapter "Technical Specifications" from page 163), 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 163).
• The mobility device is only designed for use by a single occupant whose maximum weight
does not exceed the maximum permissible load of the chair. Never use the mobility device to
transport more than one person.
18
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.
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.
19
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.
20
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.
21
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 163).
• 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 163 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 163).
• Note that the wheelchair will brake or accelerate if you change the Driving Mode whilst the
wheelchair is in motion.
22
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 electric 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 electrical vehicle
rests itself on them. They lose their effect and the electrical vehicle can tip over.
• Only drive with extreme care on soft ground, especially during uphill and downhill journeys.
In the process pay increased attention to the tip stability of the electric vehicle.

Safety Information on Wheelchairs with a Lifter
IMPORTANT - IF YOUR WHEELCHAIR IS EQUIPPED WITH A LIFTER:
Danger of injury if the wheelchair tips over!
• Never exceed the maximum permissible load (see chapter "Technical Specifications" from
page 163)!
• Avoid dangerous driving situations when the lifter is in a raised position, such as trying to
overcome obstacles like kerbs or driving up or down steep gradients!
• Never lean out of the seat when the lifter is raised!
• Inspect the lifter module at least once a month to make sure the automatic speed reduction
function, which reduces the speed of the wheelchair when the lifter is raised, is working
properly (see chapter "Fehler! Verweisquelle konnte nicht gefunden werden." from page
Fehler! Textmarke nicht definiert.)! Notify your authorised dealership immediately if it is not
working properly!
Danger of injury by moving parts!
• Never let objects get caught in the space underneath a raised lifter!
• Make sure that neither you nor anyone else is injured by placing hands, feet other body
extremities under the raised seat!
Danger of malfunction of the Lifter Module!
• Inspect the lifter module at regular intervals to make sure there are no foreign objects or
visible damage, and to make sure the electric plugs are firmly inserted into their sockets!
WARNING: Danger of injuries and damage to the wheelchair can result if the wheelchair is
lifted up or carried by the seat! The lifter motor can slip out of its fixation under the seat!!
• Never attempt to lift the wheelchair by the seat, only by its frame!
24
2.6
Safety information on maintenance work and alterations to the
wheelchair
WARNING: Danger of injuries and damage to the wheelchair, in case the suspension is
adjusted without the immobilisation mechanism of the front anti-tippers being readjusted!
• When the hardness of the suspension is adjusted, the immobilisation mechanism of the front
anti-tippers must without fail be checked and, if necessary, also re-adjusted!

Getting in and out of the wheelchair
Important information when side transferring in and out of the wheelchair
In order to side transfer it is necessary for the armrest to either be raised or removed completely
depending on the model. A skirtguard can be installed as an option in connection with the
parallel sliding armrest. This is attached in the same way as the standard armrest and must also
be removed when transferring.
4.1
Remove the standard armrest in order to side transfer
Removing the armrest:
• Disconnect the cable (1) from the remote.
• Disengage the release handle (2).
• Pull the side part out of the holder.
27
4.2
Raise the parallel sliding armrest / remove the skirtguard
(optional)
Swivelling the armrest up
• Swivel the armrest up to access from the side.
Remove the clothes guard (option) for access
• Disengage the release handle (1).
• Pull the skirt guard out of the holder.
28
Getting into the wheelchair:
• Position your wheelchair as close as possible to your seat. This might
have to be done by an attendant.
• Switch your wheelchair off.
• Apply the manual wheel lock of your wheelchair (if existing).
• Detach the skirt guard of your wheelchair or swivel it up.
• Now slide into the wheelchair.
Getting out of the wheelchair:
• Drive your wheelchair as close as possible to your seat.
• Switch your wheelchair off.
• Apply the manual wheel lock of your wheelchair (if existing).
• Detach the skirt guard of your wheelchair or swivel it up.
• Now slide onto your new seat.
NOTE:
If you do not have sufficient muscle strength, you should ask other persons for help. Use a
sliding board, if possible.
29
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 163)! 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 posture 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.
30
•
The battery charge is sufficient for the distance intended to be covered.
•
The posture belt (if installed) is in perfect order.
The gearless wheelchair has very dynamic performance!
Please observe that gearless motors have very high performance! For this reason a wheelchair
with a gearless drive has greater dynamic performance than wheelchairs fitted with conventional
motors. The top speed is also higher. Please therefore drive carefully until you have become
accustomed to the driving features of the wheelchair.
31
5.2
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.
5.3
Taking Obstacles
Your powerchair is equipped with an automatic immobilisation system for the front anti-tippers.
During normal operation the anti-tippers can move freely, allowing the powerchair to overcome
obstacles. As soon as the wheelchair starts to tip over forward and the rear wheels lose contact
with the ground, then the immobilisation mechanism locks. The anti-tippers can no longer move
and thus prevent the wheelchair from tipping over forward. The anti-tippers should be checked
once a week for smoothness of operation and correct functioning. Please see chapter "Checking
the anti-tippers for smoothness of operation and correct function" on page 150.
Your electric wheelchair can climb obstacles and kerbs of up to 8 cm in height.
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.
32
Driving up over an obstacle
Correct
• Approach the kerb or obstacle slowly head-on. Shortly before the front
wheels or kerb-lifter touch the obstacle, increase the speed and reduce
only after also the rear wheels have climbed the obstacle.
Driving down off of an obstacle
• Approach the kerb or obstacle slowly head-on. Before the front wheels
touch the obstacle, reduce the speed and keep it until also the rear wheels
have climbed the obstacle.
5.4
Incorrect
Anti-Slip-Regulation
Note
On slippery surfaces the drive tends to buck slightly. This behaviour is caused by the Anti-SlipRegulation and is entirely normal.
33
5.5
Driving up and down gradients
For information concerning the maximum safe slope, please see chapter "Technical
Specifications" starting on page 163.
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.
Braking distance is much longer on a downhill slope than on even terrain!
• Never drive down a slope that exceeds the maximum safe slope (see chapter "Technical
Specifications" on page 163).

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
Electrically disengaging gearless motors
CAUTION! Danger of the wheelchair rolling away!
• The motor brakes do not function in disengaged condition (push mode)! The pushbutton for
disengaging the motors must never be fixed in its pushed-in position using adhesive tape etc!
35
Disengaging motors:
• Press key (1). A peep tone will sound for about one
second. The motors remain disengaged until a key
is pressed (if you cannot hear the peep tone, or the
peep tone stops after around one second, there is
an error. In this case please contact your dealer.).
Re-engaging motors
• Release key (1) again. The motors are now reengaged.
36
6.2
Manually disengaging gearless motors (emergency disengaging)
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)!
The levers for disengaging the motors are located behind the drive wheels.
Disengaging the motors:
• Switch off the remote.
• Pull the locking pin (1) out and pull the engaging lever (2) backwards. The motor is disengaged.
Engaging the motors:
• Push the coupling lever (1) to the front. The motor is engaged.

The Lifter
The electric lifter is operated via the remote. Please see chapter "Operating the electric
adjustment options" on page 46.
Information regarding operation of the lifter at temperatures of less than 0 °C
Invacare® mobility aids are fitted with safety mechanisms that prevent capacity overload of the
electronic components. At operating temperatures below freezing point this can, in particular,
lead to the lifter actuator being shut down after approx. 1 second operating time.
The lifter can be raised or lowered gradually by repeatedly operating the joystick. In many cases
this generates sufficient heat for the actuator to operate as normal.
Please note – Speed restriction
The lifter is equipped with sensors that reduce the drive speed of the wheelchair as soon as the
lifter is raised or lowered above a certain point.
This is in order to guarantee the tilt stability of the wheelchair or in order to avoid damage to the
legrests.
When speed restriction is activated an appropriate blinking code is displayed on the remote.
Please see chapter "ON/OFF diode (status display)" on page 41 and chapter "Error codes
and diagnostic codes" on page 50.
In order to revert to normal drive speed move the lifter to drive height: Raise the lifter slowly if the
lifter has been lowered. If the lifter has been raised, lower the lifter until the status display stops
blinking.

8.6
Adjusting the suspension / immobilisation mechanism of the antitippers
The Invacare Zephyr can be equipped with three different types of springs. The hardness of the
springs should be selected according to the weight of the user. If springs are chosen, which are too
hard, then driving comfort wil be lost; with springs that are too soft, the powerchair will tend to
wobble.
8.6.1
Types of spring
1050 (soft)
User weight
up to 80 kg
1150 (medium)
from 70 to 100 kg
1250 (hard)
from 90 to 120 kg
Adjusting the suspension
Danger of injuries, in case the suspension is adjusted without the immobilisation
mechanism of the front anti-tippers being checked and, if necessary, re-adjusted!
• Whenever the hardness of the suspension (springs) is adjusted, the immobilisation
mechanism of the anti-tippers must without fail be checked for correct width of the gap
between the activation bolt and the small metal protrusion of the immobilisation mechanism
(see chapter "Adjusting the Immobilisation mechanism of the anti-tippers" on page 78)!
If necessary, adjust the width of the gap!
70
The hardness of the suspension can be modified by
fitting the powerchair with a different type of springs.
However, this work should only be performed by an
authorised Invacare Dealer!
By turning the knurled nut (1) a fine adjustment the
hardness of the springs can be additionally achieved.
The clearance (2) between the knurled nut and the end
of the thread should always measure between 11 and
20 mm.
The suspension should be adjusted harder in the front
than in the rear. The left and right sides should be
evenly adjusted.
• Take the load off of the spring by propping up the
wheelchair.
• Adjust the hardness of the spring by turning the
knurled nut (1).
• Repeat the procedure on the other side.
71
8.6.2

Electrical System
10.1
Electronics Protection System
The vehicle's electronics are equipped with an overload-protection system.
If the motors are put under considerable strain for a longer period of time (for example, when
driving up a steep hill) and especially when the ambient temperature is high, then the electronic
system could overheat. In this case the vehicle's power is reduced gradually until it finally comes to
a halt. The Status Display shows a corresponding error code (see chapter "Error codes and
diagnostic codes" on page 50). By switching the power supply off and back on again, the error
code is cancelled and the electronics are switched back on. It will take approximately five minutes
until the electronics have cooled down enough for the motors to restore full power again.
When the motors are stalled by an insurmountable obstacle, such as a high kerb, and the vehicle
driver allows the motors to strain against this hindrance for more than 20 seconds without moving,
then the electronics will automatically switch off to prevent the motors from being damaged. The
Status Display shows a corresponding error code (see chapter "Error codes and diagnostic
codes" on page 50). By switching off and back on again, the error code is cancelled and the
electronics are switched back on.
126
10.1.1 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 163.
The entire electric system of the wheelchair is
protected by the main fuse against overloading.
The main fuse is located under the rear centre
cowling, just to the left of the power module.
To access the main fuse, first the rear cowling must
be removed.
127
10.2
Batteries
10.2.1 What you need to know about batteries
Power is supplied by two 12V batteries. The batteries are maintenance-free and only need regular
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. How fast the batteries
will be discharged will depend 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,
etc.
128
NOTE
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.
Pay attention to the Battery Charge Indicator! Make sure to charge the batteries when the Battery
Charge Indicator shows that battery charge is low. We recommend charging the batteries after
each trip, 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.
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.
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.
In case your vehicle is not used for a longer period of time, then the batteries must be charged at
least once a month to maintain a full charge. Alternatively, the vehicle can stay connected to the
charger. The batteries cannot be overcharged with the specified charger.
Please 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.
129
10.2.2 Charging the batteries
• Make sure you read and understand the battery charger's User's Manual, if supplied, as well as
the safety notes on the front and rear panels of the charger!
WARNING: Danger 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®.
Danger of electric shock and damage to the battery charger if it is allowed to get wet!
• Protect the battery charger from water.
• Always charge in a dry environment.
Danger 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.
Danger 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.
130
Charging the batteries
• Switch off the wheelchair at the Joystick Box.
• Connect the battery charger to the Joystick Box - the
charging socket is located on the bottom of the Joystick
Box (1).
• Connect battery charger to the mains outlet and switch on
if necessary.
• After charging is complete, first disconnect the battery
charger from the mains supply, then disconnect from the
Joystick Box.
131
10.2.3 Removing and fitting batteries
WARNING:
Danger of injury if the batteries are not handled correctly during assembly and
maintenance work!

• Immediately rinse eyes under running water for several minutes; consult a physician.
132
10.2.3.1 Removing the batteries
CAUTION: Risk of fire and burns if battery poles are bridged!
• When replacing the batteries the battery poles MUST NOT come into contact with metal parts
of the wheelchair causing bridging.
• Be sure to replace the battery pole caps after the batteries have been replaced.
WARNING: Risk of fire and burns due to damage to the battery cables!
• The battery cables and other cables are positioned in a cable duct above the batteries. The
cable duct protects the cables against crushing and other damage. It may not be removed.

12.2
Checking the anti-tippers for smoothness of operation and
correct function
When testing the function of the anti-tippers, it makes no
differnce whether the user is seated in the wheelchair or
not.
Smoothness of operation
• Lift up the anti-tipper (1) and release it again. If it can be
pulled up without difficulty and it then returns by itself to
its original lower position, then it is functioning smoothly.
• In case the anti-tipper does return to its original position
by itself, then the wheelchair must be checked
immediately by an authorised Invacare Dealer!
• In case the anti-tipper jams when pulled upwards, then
the immobilisation mechanism needs to be be adjusted.
Please see chapter "Adjusting the Immobilisation
mechanism of the anti-tippers" on page 78.
• Repeat the procedure on the other side.
150
Correct function
• Have a second person lift the wheelchair up slightly in
the rear, so that the rear wheels have approximately 1
cm ground clearance.
• Pull the anti-tipper (1) upwards. The anti-tipper must lock
immediately and completely.
• In case the anti-tipper can be pulled upwards, then the
immobilisation mechanism needs to be adjusted. Please
see chapter "Adjusting the Immobilisation
mechanism of the anti-tippers" on page 78.
• Repeat the procedure on the other side.
151
13
Transport
CAUTION: Injury hazard or material
damage if an electric wheelchair which is
fitted with a table is transported in a
vehicle!
• If a table is fitted, always remove it before
transporting the wheelchair.
13.1
Transferring the wheelchair to a vehicle
WARNING: Danger of tipping over, if the wheelchair is transferred to a vehicle using a
ramp that exceeds the maximum safe slope, or if the backrest is not in an upright position
during transfer!
• If the wheelchair has to be transferred to a vehicle using a ramp that exceeds the maximum
safe slope (see chapter "Technical Specifications" starting on page 163), then a winch must
be used. An attendant can then safely oversee and assist the transfer process.
• If no winch is installed, then the wheelchair must not be transferred to a vehicle using a ramp
that exceeds the maximum safe slope.
• Alternatively, a tail lift installed in the vehicle may be used.
• Only ever transfer the wheelchair to a vehicle with the backrest in an upright position. Ensure
that the total weight of the mobility aid including the user does not exceed the highest
permissible weight for the platform lift.
• Only ever run the wheelchair with the seat back in the upright position, seat lifter lowered and
the seat tilting in the upright position into the transport vehicle (please refer to chapter
"Driving up and down gradients" on page 34).
152
• Drive or push your wheelchair into the transport vehicle using a suitable ramp.
153
13.2
Use of the wheelchair as a seat in a vehicle
Please note
In order to use a wheelchair as a motor vehicle seat, it needs to be equipped with attachment
points to enable anchoring in the motor vehicle. These accessories may be included in the
standard scope of wheelchair order and delivery in some countries (UK for example), but may
also be obtained from Invacare® as an option in other countries.
This electric wheelchair complies with the requirements of ISO 7176-19:2001 and may be used as
a vehicle seat in connection with an anchoring system that has been checked and approved in
accordance with ISO 10542. The wheelchair has undergone a crash test in which it was anchored
in the transporting vehicle's direction of travel. Other configurations were not tested. The crash test
dummy was secured using pelvic and upper body safety belts. Both types of safety belt should be
used in order to minimise the risk of injuries to head or upper body. It is imperative that the
wheelchair is inspected by an authorised dealer before being used again after being involved in a
crash. Alterations to the wheelchair anchoring points may not be carried out without the
manufacturer's permission.
154
Caution: There is a danger of injury if the wheelchair is not properly secured during use
as a vehicle seat!
• If possible, the user should always leave the wheelchair to use a vehicle seat and the safety
belts provided with the vehicle.
• The wheelchair should always be anchored facing in the transport vehicle's intended direction
of travel.
• The wheelchair must always be secured in accordance with the wheelchair and anchoring
system manufacturers’ operating manual.
• Always remove and secure any accessory parts fixed to the wheelchair such as chin controls
or tables.
• If your wheelchair is equipped with an angle adjustable backrest, then it must be placed in an
upright position.
• Fully lower elevated legrests, if fitted.
• Fully lower the seat lifter, if fitted.
WARNING: Danger of injury exists if a powerchair that is not equipped spill-proof
batteries is transported in a vehicle!
• Only ever use spill-proof gel batteries!
155
13.2.1 How the wheelchair is anchored in a vehicle for use as a vehicle seat
The electric wheelchair is fitted with four anchoring points, which are labelled
with the symbol shown on the right. Snap hooks or belt loops can be used for
fixation.
• Secure the wheelchair in the front (1) (only left side visible in the picture) and rear (2) with the
anchoring system belts.
• Secure the wheelchair by tensioning the belts in accordance with the manufacturer's anchoring
system operating manual.
156
13.2.2 How the user is secured within the wheelchair
CAUTION: There is a danger of injury if the user is not properly secured within the
wheelchair!
• Even if the wheelchair is fitted with a postural belt, this is no substitute for a proper safety belt
which complies with ISO 10542 in the transport vehicle. Always use the safety belt installed in
the transport vehicle.
• Safety belts must be in contact with the user's body. They must not be held at a distance from
the user's body using parts of the wheelchair such as armrests or wheels. Refer to the
illustration on page 158.
• Safety belts must be pulled as tightly as possible without causing the user discomfort. Refer
to the illustration on page 158.
• Safety belts must not be positioned while twisted.
• Ensure that the third seatbelt anchorage point is not fixed directly to the vehicle floor, but to
one of the vehicle uprights.
157
Seat belts may not be held at a distance
from the user's body using parts of the
wheelchair such as armrests or wheels.
158
The pelvic belt should be positioned in the
area between the user's pelvis and thighs
so that it is unobstructed and not too loose.
The ideal angle of the pelvic belt to the
horizontal is between 45° and 75°. The
maximum permissible angle is between
30° and 75°. The angle should never be
less than 30°!
The safety belt installed in the transporting
vehicle should be applied as shown in the
illustration at right.
1) Centre line of the body
2) Centre of the sternum

13.3
Securing the wheelchair for transport without passengers
CAUTION: Injury hazard!
• If you are unable to fasten your electric wheelchair securely in a transport vehicle, we
recommend that you do not transport it!
• Before transporting your wheelchair, make sure the motors are engaged and that the Joystick
Box is switched off.
• We urgently recommend securing the wheelchair to the floor of the transporting vehicle.
