1 Introduction
Dear Customer,
First we would to thank you for choosing an Invacare® product. We hope you will be satisfied with your
new Powerchair and that it will bring you much enjoyment.
This wheelchair combines attractive design with a new dimension in mobility and driving pleasure.
Thanks to its unique modular construction, the STORM can be easily adapted to almost any personal need:
• Our different seating systems (like the Invacare® Kontur Seat, Invacare® Ultimate and Personal
Seating Systems or the Recaro Seat) are designed to fit your personal needs and wishes.
• An optional Lifter Module provides the capability to increase the height of the seat by up to
approximately 30 cm!
• Powerful 6 and 10 km/h motors make driving a pleasure in both indoor and outdoor environments.
By adjusting the wheelbase and the seat depth, the driving characteristics of the Powerchair can be
•
optimised for you.
9
• The individually programmable Invacare® Advanced Control System (ACS) allows fine-tuning of all
driving characteristics.
• The compact design guarantees excellent manoeuvrability and easy transport.
• Thanks to a well thought-through concept, most special design requirements can be easily taken care of
at the time of prescription. Later retro-fitting is possible, however this requires more work and should be
performed by trained personnel.
• The orderly construction of the wheelchair make service and maintenance easy.
This User's Manual contains important information and instructions on the following subjects:
• Safety
• Operation
• Care and maintenance
Please familiarise yourself with these instructions before going for your first drive. We cannot be
held responsible for any damage or faults that result from failure to comply with the instructions
put forth in this manual.

11
2 Safety Notes
• READ WELL BEFORE OPERATION!
2.1 General Safety Notes
Danger of injury if wheelchair is used in any other way than the purpose described in this
manual!
• Adhere strictly to the instructions in this User's Manual!
Danger of injury if the wheelchair is driven when ability to operate a vehicle is impaired by
medication or alcohol!
• Never drive the wheelchair under the influence of medication or alcohol!
Danger of damage or injury if wheelchair is accidentally set into motion!
• Switch the wheelchair off before you get in, get out or handle unwieldy objects!
• Be aware that there are only the motor brakes to stop your wheelchair. When the motors are
disengaged, these brakes are automatically deactivated. For this reason, pushing the
wheelchair by an attendant is only recommended on flat surfaces, never on gradients. Never
leave your wheelchair on a gradient with its motors disengaged. Always re-engage the
motors immediately after pushing the wheelchair.
12
Danger of injury if the On/Off Button is pressed while the wheelchair is in motion, 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!
Danger of injury when transferring wheelchair to another vehicle for transport with the
occupant seated in it!
• It is always better to transfer the wheelchair to another vehicle without the occupant seated in
it!
• In case the wheelchair does need to be transferred to another vehicle over a ramp with the
occupant seated in it, always have an attendant stand behind the wheelchair during transfer
to ensure it does not tip over backwards!
Danger of injury, if the wheelchair is used as a vehicle seat without a special restraining
system!
• Only ever use the wheelchair as a vehicle seat in connection with a Wheelchair Restraint
System and with the safety belts of the transporting vehicle! Make sure to follow the
instructions and recommendations issued by the Restraint System's manufacturer!
Danger of injury if maximum permissible load is exceeded!
• Do not exceed the maximum permissible load (see technical specifications)!
Danger of injury if legrests break due to use as a stepping board!
• Do not use the legrests as a stepping board when getting in and out of the wheelchair!
13
Danger of injury due to wrong lifting or dropping of heavy components!
• When maintaining, servicing or lifting any part of your wheelchair, 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 wheelchair.
• 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 restraining systems are installed (such as seat belts), use them each time you drive the
wheelchair.
• When changing over to a new seat, position the wheelchair 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 wheelchair, 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 wheelchair that are not expressly certified by
Invacare® for this purpose! Have all electrical installations done by your authorised
Invacare® Dealer!
14
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 vehicle 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 vehicle is to be operated on public roads, the vehicle driver is responsible for ensuring
that the vehicle is in an operationally reliable condition! Inadequate or neglected care and
maintenance of the vehicle will result in a limitation of the manufacturer's liability!
15
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!
16
2.4 Safety Information on Driving and Freewheel Mode
Danger of injury if the wheelchair tips over!
• Only ever negotiate gradients of up to the maximum defined in the Technical Specifications
and only with the backrest and seat tilt in an upright position!
• 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!
• Always approach obstacles straight on! Ensure that the front wheels and rear wheels move
over the obstacle in one stroke, do not stop halfway! Do not exceed the maximum obstacle
height (see Technical Specifications)!
• 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 maximum permissible load!
• Note that the wheelchair will brake or accelerate if you change the Driving Mode whilst the
wheelchair is in motion!
17
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!
18
2.5 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 Technical Specifications)!
• 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 on lifter)! 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!
19
2.6 Safety Information on Wheelchairs with Recaro Seats
Danger of injury if the wheelchair tips over!
The centre of gravity of a Recaro seat is higher than that of other seats. The Recaro seat is
also heavier than other seating systems. The backrests of RECARO seats can be leaned
back 90°. For these reasons there is an increased risk of tipping over!
• Never lean the backrest backward more than 30° degrees, and never exceed 15° when
driving the wheelchair!
20
More than 30° 15°-30° 0°-15°

22
5 Driving
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, use the restraining systems (seat belts) each time you use the vehicle.
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 seatbelt is in perfect order.
23
5.2 Taking Obstacles
Your wheelchair can overcome obstacles and kerbs with the following heights.
• STORM with front wheel type 200x50: 4 cm
• STORM with front wheel type 3.00x4”: 6 cm
• STORM with kerb climber: 10 cm
CAUTION: Danger of Tipping Over!
• Never approach obstacles at an angle!
• Put your backrest into an upright position before climbing an obstacle!
Driving up over an obstacle
• 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.
Correct
24
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.
Incorrect
5.3 Driving up and down gradients
The STORM can safely climb gradients of up to 18%.
When driving up or down gradients you should always observe the following precautions:
WARNING: Danger of tipping over!
• Only ever drive downhill at a maximum of 2/3 of the top speed!
• 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 or the seat tilt slightly to the rear
before descending slopes!
• 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 you leave your wheelchair standing still for a longer period of time:
• Switch the Joystick Box OFF (ON/OFF Button).
When parking your vehicle:
• Activate the Drive Away Interlock, if available.
25
5.5 Hand brake
The 10 Km/h version of the STORM is equipped with an additional
hand brake. The brake lever is normally mounted on the opposite
side from the Joystick Box. Alternatively, the brake lever can be
mounted on the same side as the Joystick Box with a special holder.
• To activate the brakes push the brake lever forward, to release
pull the lever backwards.
26
6 Pushing the wheelchair by hand
6.1 Disengaging Motors
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, the
magnetic brakes must be disengaged.
Danger of the vehicle running away!
• When the motors are disengaged (for push operation), the electromagnetic motor brakes are
deactivated! When the vehicle is parked, the levers for engaging and disengaging the motors

7.2 Main components of the Joystick Box
7.2.1 Battery Charge Display
The battery charge display (1) shows you the current charge status
of the batteries.
It is subdivided into 10 different-coloured LEDs:
2 x red, 4 x yellow and 4 x green.
The decreasing battery charge, and thus the Powerchair's
decreasing travelling range, is indicated by the individual diodes
going out.
Meaning of the Display:
• All diodes illuminated: full travelling range = batteries fully
charged
• Only the red diodes illuminated: Diminished travelling range =
charge batteries at end of trip
• Both of the red diodes flash: very low travelling range = charge
batteries as soon as possible
• Only one red diode flashes: Battery reserve = charge batteries
immediately!
The travelling range on battery reserve is very low. After a certain
travelling time, the electronics will switch off the drive automatically
and bring the Powerchair to a standstill = full discharge protection.

11 Lifter (option)
The seat-lifting system for the STORM, called the STORM Lifter, is a useful
option that provides the active user with more flexibility by lifting the seat up to
30 cm. It is available in two versions: the one allows a permanent adjustment
of the seat tilt by means of adjustment screws, the other is equipped with an
electric actuator for this purpose.
NOTE:
As soon as the lifter is raised, the STORM moves at a reduced speed.
To increase your speed again, lower the lifter completely. For a
detailed description, see the part on automatic speed reduction
below.
In all other respects the STORM Lifter model is the same as other
models of the STORM Series.

12 Electrical System
12.1 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. 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. By switching off and back on again, the error
code is cancelled and the electronics are switched back on.
95
12.2 Batteries
12.2.1 What you need to know about batteries
Power is supplied by two 12V gel 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.
96
NOTE
Gel batteries 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. Gel 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® and comply with these
requirements.
97
12.2.2 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!
98
