2 Introduction
Dear Customer,
First of all we wish to thank you for your confidence in our products. We hope you will enjoy your new
Harrier XHD
TM
powered wheelchair.
This manual contains important information and hints on:
• Safety
• Operation
• Care and maintenance
The information contained in this document is subject to change without notice.
As a manufacturer of wheelchairs, INVACARE endeavours to supply a wide variety of wheelchairs to meet
many needs of the customer. However, final selection of the type of wheelchair to be used by an individual
rests solely with the user and his/her healthcare professional capable of making such a selection.
Do not operate this equipment without first reading and understanding this manual. If you are unable to
understand the warnings, cautions, and instructions, contact your dealer otherwise injury or damage may
result.
The initial set up of this wheelchair must be performed by an experienced technician.
Procedures other than those described in this manual must be performed by an experienced technician.
9
Note:
Not all of the components within this manual will necessarily be available with your powered wheelchair. Any
references not applicable to your product should be ignored.
2.1 Intended Use
Indoor and outdoor configurable wheelchair offered with various options compliant with EN12184:2009
section 5 class B.
The Harrier XHDTM powered wheelchair has been designed to provide mobility and comfort for persons with
impaired mobility.
The wheelchair has been designed to be used either/or by a seated user/carer/attendant in both indoor and
outdoor environments.
The wheelchair has, in its standard format, been designed to accommodate users who have all limbs intact and
have sufficient upper body strength to maintain a safe position within the wheelchair without the addition of
supporting aids.
Adaptations from the standard wheelchair format are available to accommodate users who do not meet these
criteria, these will only be considered after a suitable risk assessment has been carried out by the product
prescriber. When prescribing wheelchairs for use by full or partial amputees (above or below knee, single or
double) it is important to recognise that lower limb amputation will affect the sitting centre of balance of the
wheelchair. The impossibility of generalising the individual ability of a wheelchair user means it is imperative
that the product prescriber carries out a full stability evaluation to ensure that the user is safe in the use of
the wheelchair and the risk of the wheelchair tipping is minimised.
The wheelchair should only be used in accordance with the safety advice given within this user guide. Failure to
follow the recommended advice within this user guide could lead to personal injury.
10

3.3
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 the electric
vehicles. Also, the electronics used in our vehicles can generate a low level of electromagnetic interference,
which however will remain within the tolerances 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 telephones) when the vehicle is switched on!
• Avoid getting too close to strong radio and television transmitters!
• In case the vehicle should be set in motion unintentionally or the breaks 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 electronic brakes to the
manufacturer!
15
3.4
Safety Precautions/Safe Operations
• The day to day activities and the more advanced powered wheelchair techniques depend, on your physical
capabilities and your own specific circumstances. Our recommendations may occasionally differ from those
of your therapeutic adviser or physician, as they may have a better understanding of your abilities. Where
this is the case, you must follow their advice, they are better placed to tell you what is suitable for you and
what is not.
• Do not use your powered wheelchair when your driving ability is impaired by medication or alcohol.
• Avoid using your powered wheelchair on rough ground or in adverse weather conditions (snow or ice),
always steer clear of obstacles where possible, ensure your clothing and hands are kept clear of all moving
parts, ask for assistance when descending or ascending steep gradients. Never attempt to negotiate stairs.
Never use an escalator to move a powered wheelchair between floors. Due to both the weight of a
powered wheelchair and its occupant it is not advisable to attempt to be assisted up and down stairs whilst
the powered wheelchair is occupied.
• If you are a user with limited mobility we advise that in the case of adverse weather conditions, i.e.
extreme cold, do not attempt a journey without an accompanying attendant. In an event of a power failure
you could become stranded in an isolated area, where there is the strong possibility you will be unable to
get immediate assistance.
• Braking of your powered wheelchair is dependant on electromagnetic motor brakes. When these are
disengaged by declutching the motor gear box drive system, the chair is in freewheel mode, this mode is
for emergency use only and motor gearboxes should remain engaged at all other times.
• To avoid the powered wheelchair free wheeling special care must be taken to engage motor brakes.
• When using your powered wheelchair indoors always consider the following potential hazards:
o Beware of the fact that many of the premises where you are likely to use your powered wheelchair
may not have been designed with this consideration in mind. You should therefore have an
awareness for safety when encountering the likes of narrow doorways, steps, high surfaces,
protruding wall fittings and every day household items such as electrical appliances, etc. Take extra
care in kitchen environments.
Consider the fire evacuation procedures for buildings you may be entering. Never put yourself at risk, and
ensure that you can be evacuated in the event of an emergency.
16
NOTE
Powered wheelchairs drive very quietly, generally travel faster than the average walking pace and are low to
the ground. Always consider these factors when using your powered wheelchair in busy pedestrian areas.
• Coping with the irritation of everyday obstacles can be alleviated somewhat by learning how to manage
your wheelchair. Keep in mind your centre of gravity to maintain stability and balance.
• When learning a new technique, have an experienced assistant help you before attempting it alone.
SAFETY/HANDLING OF WHEELCHAIRS
• Use this information only as a ‘basic’ guide. The techniques that are discussed on the following pages have
been used successfully by many.
• Individual wheelchair users often develop skills to deal with daily living activities that may differ from those
described in this manual. INVACARE recognises and encourages each individual to try what works best for
him/her in overcoming environmental obstacles that they may encounter, however all warnings and
cautions given in this manual must be followed. Techniques in this manual are a starting point for all new
wheelchair user and assistant with ‘safety’ as the most important consideration for all.
17
RECOMMENDED DRIVING POSITION
• INVACARE recommends that when driving your powered wheelchair during normal operating conditions
the following seat and back angles are maintained:
• Seat Angle: - approximately 4°
• Back Angle: - approximately 7°
• Failure to observe the above precautions whilst driving may lead to instability, damage to the chair, user or
those around you.
SURFACES AFFECTED BY HEAT
The wheelchair is made from metal and plastic materials and, as with all products made with such materials, it
can absorb heat from the sun when used outdoors or exposed to sunlight through windows, etc. This can
result in the surfaces of the wheelchair becoming hot, so take care in using it and touching the surfaces if it is
left or used in such an environment.

Some Useful Tips
• Before you venture off on your first journey, ensure that everything is adjusted to your specific needs, read
this manual to familiarise yourself with the product and its functions. Do not attempt to drive without an
attendant on hand until you are fully proficient in using and maneuvering your powered wheelchair.
• Ensure power is switched off before transferring to or leaving your powered wheelchair. Before switching
on, check that both motors are engaged, tyres are inflated to the correct pressure and are in good
condition. When on the move do not attempt turns at full speed, especially while traveling downhill. Before
changing from forward to reverse, and vice versa, you must stop. Failure to do so will cause severe damage
to the electronics. Do not use your powered wheelchair beyond its limitations.
• When entering or leaving your powered wheelchair, do not stand on the footplates.
• If you have to brake in an emergency, release the joystick. Do not switch off power while the powered
wheelchair is moving, it would cause an abrupt, sharp stop.
• Do not use your powered wheelchair beyond the limitations set out in this manual concerning kerb height,
gradients, etc.
STABILITY AND BALANCE
To ensure stability and safe control of your powered wheelchair you must at all times maintain proper
balance. The powered wheelchair is designed to remain stable and upright during normal use, so long as you
do not move your centre of gravity outside the normal seating position.
REACHING - BENDING FORWARD
• Ensure power is OFF. Do not lean your body forward out of the powered wheelchair further than the
length of the armrests.
• Do not attempt to pick up objects from the floor by bending forward and reaching between your knees.
• Do not attempt to reach objects by sliding forward to the edge of the Powered wheelchair seat.
19
REACHING - BENDING BACKWARDS
• Again ensure power is switched OFF.
• Do not reach back any further than your arm will extend without changing your sitting position.
• Do not lean over the top of the backrest as it will shift the centre of gravity, risking tipping over.
• Do not hang heavy loads or objects on the backrest. They may make the powered wheelchair unstable,
especially on an incline.
TRANSFERRING TO AND FROM OTHER SEATS
• Always turn the wheelchair power OFF and engage the motor locks/clutches to prevent the wheels from
moving before attempting to transfer in or out of the wheelchair. Also, make sure every precaution is
taken to reduce the gap distance by turning both front castors away from the object you are transferring
onto.
• When transferring, position yourself as far back as possible in the seat. This will prevent broken screws,
damaged upholstery and the possibility of the wheelchair tipping forward.
• Note: This activity may be performed independently provided you have adequate mobility and upper body
strength.
• Position the wheelchair as close as possible along side the seat to which you are transferring, with the rear
wheels pointing away from it.
• Shift body weight into seat with transfer.
• During independent transfer, little or no seat platform will be beneath you. Use transfer board if at all
possible.
20
NEGOTIATING KERBS
When approaching kerbs wherever possible mount
and dismount pavements via ramps. Always approach
the kerb head on, not at an angle.
Without a Kerb Climber
Your Powered wheelchair can safely climb kerbs of
up to 5cm without a kerb climber. Before negotiating
the kerb, ensure the speed control setting is set to
maximum. As the front wheels are about to make
contact with the kerb push the joystick fully forward
and hold it there until both front and rear wheels
have climbed the kerbstone.
With a Kerb Climber
If a kerb climber (optional) is fitted, your powered
wheelchair can safely climb kerbs of up to 10cm.
Before negotiating the kerb ensure the speed control
setting is set to maximum and the kerb climber is in
the engaged position (facing forward). As the kerb
climber makes contact with the kerb push the
joystick fully forward and hold it there until both rear
wheels have climbed the kerbstone. Your powered
wheelchair prescriber will provide you with a
demonstration and instructions on fitting.
If the kerb climb is unachievable do not continue the
maneuver, move away from the obstacle and if
possible find an alternate location.
21
Descending a Kerb
1. Do not descend kerbs over 10cm.
2. Approach the edge of the kerb square on.
3. Look out for traffic.
4. Drive forward down the kerb.
The kerb climbing device should return to the
climbing position after each maneuver. If you require
further advice, please contact your INVACARE
dealer.
NEGOTIATING GRADIENTS/SLOPES
• The maximum safe slope is 9°.
• Never attempt to climb or descend an incline where the surface is rough, wet or slippery (gravel, loose
chippings, grass, rain, black ice, snow, etc.).
• If you are in a situation where by the powered wheelchair fails to climb a ramp and stalls midway through
the ascent, do not attempt to turn the powered wheelchair to drive back down in a forward facing
direction, always reverse slowly in a steady, flowing action and do not brake harshly, as this will upset
balance in this situation. If possible, always seek the assistance of an attendant.
Direction of Travel
22
YOU, YOUR POWERED WHEELCHAIR & OTHERS
• Powered wheelchairs are strictly forbidden on motorways and highways with fast moving traffic (please
refer to section 2.2 ‘Type Classification’).
• On the pavement, in pedestrian zones or in supermarkets it is obvious that you must show as much
consideration and common sense to others as you expect from them.
• When you cross the carriageway of a public road take extra care and allow time to cross, observe the
highway code. Although you are not required by law to hold a driving license, you are responsible and fully
liable for proper operation. An important fact to bear in mind is that you must not present a traffic hazard
even in the event of a breakdown. The most common cause may be discharged batteries. It is important to
keep the batteries in a fully charged condition; we can only repeat this warning at this stage. If you do suffer
a breakdown for whatever reason, you should immediately: seek the assistance of a passer-by. Explain
where to find the motor disengagement/declutching lever, ask him/her to switch to freewheel, so that the
Powered wheelchair can be pushed by hand and moved. When in a safe place always ensure motor gear
boxes are re-engaged.
SAFEGUARDING OTHERS
• We want you to get the most out of your INVACARE powered wheelchair, ensuring that the safety of
yourself and others is never in jeopardy. If you are in any doubt about safe techniques, handling or care of
the powered wheelchair, contact a recognised expert before putting yourself and others at risk.
