15
2.2 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
2.3 Safety Information on Driving and Freewheel Mode
Danger of injury if the wheelchair tips over!
• Only ever negotiate gradients up to the maximum tilt-resistant gradient (see 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
2.4 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
2.5 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 45° degrees, and never exceed 15° when driving
the wheelchair!
20
More than 45° 15°-45° 0°-15°

4 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:
• Loosen remote cable (1) from remote.
• Loosen clamping lever (2)
• Remove the side panel from the receptacle
22
4.2 Raise the parallel sliding armrest / remove the skirtguard (optional)
Swivel up armrest
• Swivel armrest up to access from the side.
Removing the skirtguard (optional) to get on:
• Loosen clamping lever (1)
• Remove the skirtguard from the receptacle.
23
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 hand brake of your wheelchair (if existing).
• Detach the side part 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 hand brake of your wheelchair (if existing).
• Detach the side part 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.
24
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.
25
5.2 Taking Obstacles
5.2.1 The ”SureStep“ System
The Invacare® Typhoon is fitted with "SureStep" technology. When climbing over obstacles, the
front steering wheels are raised using the torque generated by the drive wheels.
Please note that the techniques required for overcoming obstacles for wheelchairs fitted with
central drives and "SureStep" technology is completely different to that required for models with
front wheel or rear wheel drive.
5.2.2 The ”Stability Lock“ System
If your wheelchair is fitted with a lifter and this is raised, this will restrict the function of the
"SureStep" system due to the "Stability Lock". The "Stability Lock" increases the tilt stability of the
wheelchair and prevents front wheel spring deflection on the "Walking Beams" when braking or
when descending slopes.
26
5.2.3 The components of the "SureStep" and the "Stability Lock" system
The diagram below shows the components in the "SureStep" system with the side panels removed.
(1) Anti-Dive Spring, (2) Walking Beam und (3) Stability Lock.
5.2.4 Maximum obstacle height
Your wheelchair can overcome obstacles and kerbs with the following heights.
• 10 cm
27
5.2.5 Safety information when ascending obstacles
CAUTION: Danger of Tipping Over!
• Never approach obstacles at an angle!
• Put your backrest into an upright position before climbing an obstacle!
CAUTION: The wheelchair can be damaged if an obstacle is approached at excessive
speed.
• Always approach obstacles at low speed! As soon as the front wheels come into contact with
the obstacle, stop for a short period before driving over the obstacle! Wheelchairs fitted with
centre drive have a special mechanism (Walking Beam) for overcoming obstacles.
Approaching at speed can actually lead to mechanical damage.
5.2.6 Safety information when descending obstacles
CAUTION: The wheelchair can tip over to the front when descending from an obstacle that
is too high as there can be spring deflection of the front swivel wheels.
• Please pay particular attention to tilt resistance when driving down off an obstacle!
• If available, please set your seat tilt to a greater value than normal!
• The maximum obstacle height refers to ascent as well as descent. Never descend from
obstacles that are higher than those you may ascend!
28
5.2.7 The correct way to overcome obstacles
CAUTION: If the lifter is raised, the drive wheels can lose ground contact when
descending from obstacles or driving on an uneven surface! The "Stability Lock"
prevents “Walking Beam“ spring deflection when the lifter is raised!
• Never descend from obstacles when the lifter is raised or drive on an uneven surface!
• In the event of the drive wheels losing ground contact, the lifter must be lowered so that the
drive wheels come into contact with the ground again.
Ascending and descending
The same approach applies to both ascending and descending obstacles:
• Approach the obstacle or the kerb slowly and at a right angle.
• Stop shortly before the front wheels come into contact with the obstacle.
• Check the position of the front wheels. They must be in driving direction
and vertical to the obstacle!
• Approach slowly and keep at a consistent speed until the rear wheels
have also passed over the obstacle.

Wrong
29
5.3 Driving up and down gradients
The Invacare® Typhoon has a maximum hill-climbing ability without overturning of 20%.
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 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!
• If the lifter is raised drive mode is only used for positioning and not for regular drive operation!
Lower the lifter before ascending 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
30
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.
