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.

11

2 Safety Notes
2.1 Repair or service information
Setup of the Electronic Control Unit is to be performed ONLY by individuals certified by Invacare.
The final tuning adjustments of the controller may affect other activities of the wheelchair. Damage to
the equipment could occur under these circumstances. If non-certified individuals perform any work
on these units, the warranty is void.
2.2 General safety notes
GENERAL WARNINGS
• Performance adjustments should only be made by professionals of the healthcare field or
persons fully conversant with this process and the driver's capabilities. Incorrect settings could
cause injury to the driver, bystanders, damage to the chair and to surrounding property.
• After the wheelchair has been setup, check to make sure that the wheelchair performs to the
specifications entered during the setup procedure. If the wheelchair does NOT perform to
specifications, turn the wheelchair OFF immediately and re-enter setup specifications. Repeat
this procedure until the wheelchair performs to specifications.
• DO NOT climb, go up or down ramps or traverse slopes greater than 9°.
• DO NOT attempt to move up or down an incline with a water, ice or oil film.
• DO NOT attempt to drive over curbs or obstacles greater than 50mm (2in) in height. Doing so
may cause your wheelchair to turn over and cause bodily harm or damage to the chair.

15
• Always stop before climbing an obstacle. Approach slowly until castors contact the obstacle.
Apply power and the action of the Sure-Step™feature will lift the castors over the obstacle.
Weight is transferred to the drive wheels providing traction and motor strength to power the
chair over the obstacle.
• DO NOT use parts, accessories, or adapters other than those authorised by Invacare.
• DO NOT stand on the frame of the wheelchair.
TYRE PRESSURE
• DO NOT use your wheelchair unless it has the proper tyre pressure (P.S.I.). DO NOT
overinflate the tyres. Failure to follow these suggestions may cause the tyre to explode and
cause bodily harm. The recommended tyre pressure is listed on the side wall of the tyre.
BATTERIES
• The warranty and performance specifications contained in this manual are based on the use of
deep cycle gel cell batteries. Invacare strongly recommends their use as the power source for
this unit.
• Carefully read battery/battery charger information prior to installing, servicing or operating your
wheelchair.
ELECTRICAL
• Extreme care should be exercised when using oxygen in close proximity to electrical circuits.
Contact your oxygen supplier for instructions in the safe use of oxygen.

16
RAIN TEST
• INVACARE has tested its power wheelchairs in accordance with ISO 7176 Part 9 “Rain Test”.
This provides the end user or his/her attendant sufficient time to remove his/her power wheel-
chair from a rain storm and retain wheelchair operation.
• DO NOT leave power wheelchair in a rain storm of any kind.
• DO NOT use power wheelchair in a shower or leave it in a damp bathroom while taking a
shower.
• DO NOT leave power wheelchair in a damp area for any length of time.
• Direct exposure to rain or dampness will cause the chair to malfunction electrically and me-
chanically and may cause the chair to rust prematurely.
• Check to ensure that the battery covers are secured in place.
• DO NOT use the joystick if the boot is torn or cracked. If the joystick boot becomes torn or
cracked, replace IMMEDIATELY.
WEIGHT TRAINING
• Invacare DOES NOT recommend the use of its wheelchairs as a weight training apparatus.
Invacare wheelchairs have NOT been designed or tested as a seat for any kind of weight
training. If occupant uses said wheelchair as a weight training apparatus, Invacare shall NOT
be liable for bodily injury and the warranty is void.
WEIGHT LIMITATION
• The XTERRA GT has a maximum user weight limitation of 114kg (18stone).

17
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 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 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 electronic
brakes to the manufacturer!

18
2.4 Safety precautions/safe operation
IMPORTANT WARNING
• The day-to-day activities and the more advanced power chair techniques depend, on your
physical capabilities and your own specific circumstances. Our recommendations may occa-
sionally differ from those of your Therapeutic Adviser or Physician, as they 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 power chair when your driving ability is impaired by medication or alcohol.
CAUTION
• Avoid using your power chair 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 power chair between floors. Due
to both the weight of a power chair and its occupant it is not advisable to attempt to be assisted
up and down stairs whilst the power chair 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 the 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 power chair is dependent 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 gear boxes should remain engaged at all other
times.
• To avoid the power chair freewheeling, special care must be taken to engage motor brakes.

19
SAFETY INDOORS
• When using your power chair indoors always consider the following potential hazards:
•Beware of the fact that many of the premises where you are likely to use your power chair may
not have been designed with this consideration in mind.You should therefore have an aware-
ness for safety when encountering the likes of narrow doorways, steps, high surfaces, protrud-
ing wall fittings and every day household items such as children’s toys, 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 easily evacuated in the event of an emergency.
NOTE
power chairs 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 EVERYDAY OBSTACLES
• 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.
• DO NOT attempt to lift the wheelchair by any removable (detachable) parts. Lifting by means of
any removable (detachable) parts of a wheelchair may result in injury to the user or damage to
the wheelchair.
• Also, be aware of detachable parts such as armrests or legrests. These must NEVER be used
for hand-hold or lifting supports, as they may be inadvertently released, resulting in possible
injury to the user and/or assistant(s).
• When learning a new assistance technique, have an experienced assistant help you before
attempting it alone.

20
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.
