GENERAL SAFETY INSTRUCTIONS
These Instructions for Use should be available to the User, or their
representative at all times.
In order for the User to gain maximum advantage from the Invicta wheelchair and
for it to be used as safely as possible, it is essential that the initial setting-up and
adjustment of the wheelchair components, together with the tuning characteristics
of the power drive controller, are carried out by suitably qualified personnel who will
ensure that the wheelchair is set to meet your individual requirements.
Where the User is taking medication, the prescribing doctor / physician should be
consulted to confirm that it is safe to drive the wheelchair whilst taking the
medication.
The wheelchair should never be driven by anyone under the influence of alcohol or
illegal drugs.
As the maximum speed of the Invicta IP models is 4mph they are therefore suitable
only for indoor use and for limited outdoor use on footpaths and designated
pedestrian areas. They are NOT suitable use on the public highway except for the
purpose of crossing the road at pedestrian crossings or wheelchair suitable points
where the kerbs have been lowered.
Wherever possible, traversing driveways, slopes and ramps should be avoided.
The maximum slope / ramp angle for driving up or down is 10°.
The maximum obstacle climbing height, is 50mm (2 inches).
To exceed either of these limits could severly affect the overall stability of the
wheelchair, causing it to tip and lead to possible injury to the User.
Do NOT exceed the maximum User weight limits of 100Kg (15.7stones) for non-
vehicle transportable Users, or 50Kg (7.8 stones) for Users who are transported in
their wheelchair in a motor vehicle.
It is recommended that new powered wheelchair Users, take time to build up their
driving skills. Patience and Practice will be required by both Users and their
experienced Assistants, while learning various manoeuvres.
Navigating day to day obstacles with confidence, will be achieved with appropriate
training and practice.
The User should also be aware that, as the powered wheelchair operates very
quietly and is capable of travelling faster than some walking speeds, these aspects
could create a hazard to others especially in congested pedestrian areas.
Users of the IPC-T model Invicta with Power Tilt, should also be aware of the
following potential risks:-
1. There is a possibility of fingers being trapped, between the Sidearm Mounting
Bracket and Chassis Frame when the Seat is being lowered from a tilted
position. A Warning Label is applied to the Chassis Frame in this area to
warn of the risk.
2. There is also a potential risk of finger trapping at the rear of the Seat where the
Seat mounting brackets run on the actuator guides. A Warning Label is applied
to the Chassis Frame in this area to warn of the risk.

Electro-Magnetic Interference
The Invicta IPC-S and IPC-T model wheelchairs have been successfully tested in
accordance with international standards as to their compatibility with (EMI)
regulations. However, electromagnetic fields, such as those generated by radio and
television transmitters and cellular phones, can influence electrically powered
vehicles.
To reduce the danger of Malfunction due to Electromagnetic Interference, the
following points should be noted:-
 Portable communication devices such as Radio Transceivers, Cellular Phones
and “Walkie-Talkie” devices should not be operated in close proximity to the
wheelchair, whilst the wheelchair is “Swiched On”
 Avoid getting into close range of powerful radio and television transmitters.
 Should the wheelchair be set into unintentional motion, or the electro magnetic
brakes released unexpectedly, “SWITCH OFF” the wheelchair immediately.
 By adding electrical accessories to your wheelchair or modifying the original
equipment electrical system could change the wheelchair’s susceptibility to EMI.
 Both Invicta models are currently able to provide an immunity level of 20V/m
which should protect against common sources of EMI.
 Any occurances of unintentional movement of the wheelchair, including
uncontrollable directional control, or unexpected release of the electromagnetic
brakes, should be reported to your wheelchair supplier as soon as possible.
Environmental Conditions
Environmental conditions may affect the safety and performance of your power
wheelchair. Water and extreme temperatures are the main elements that can cause
damage and affect the power drive performance.
 Rain, Sleet and Snow —If exposed to water, the power drive system is
susceptible to damage to electrical or mechanical components. Water ingress
can cause electronic malfunction or promote premature corrosion of electrical
components.
 DO NOT leave the wheelchair parked outside in the rain.
 DO NOT park the wheelchair in a washroom/bathroom while taking a shower.
 Temperature —Some parts of the power wheelchair are susceptible to changes
in temperature. The Controller can only operate within a temperature range
between 18°F (-8°C) and 122°F (50°C).
At extreme low temperatures, the batteries could freeze and the wheelchair may
not be able to operate. In extreme high temperatures it may operate at slower
speeds due to a safety feature within the Controller that prevents damage to the
drive motors and other electrical components.
 Care must also be taken in hot weather. DO NOT leave the wheelchair parked
where it will be exposed to the sun, as the surfaces of the wheelchair can absorb
the heat and therefore become very hot to touch.
10

Transferring to and from the Wheelchair.
Before attempting to transfer into the wheelchair, the following points should be
noted:-
 To reduce the efforts sometimes required, to complete the transfer into a
wheelchair, it should be positioned as close as possible to the User’s position.
 The power must be “Turned Off”.
 The Free Wheel Lever set to the “Drive” (Forward) position and both Parking
Brakes applied. See Figs. 1 and 2.
 Remove Armrests if required.
 Raise both Footplates or swing-away both hangers. See Figs. 1 and 3.
 Stability of the stationary wheelchair can be improved by pointing both Castor
Wheels towards the direction of transfer.
NOTE: Never use the wheelchair footplates to stand on during transfers.
Reaching and Leaning when seated in the Wheelchair.
 The Pelvic Belt (Lap Belt) supplied with the wheelchair, should be the first thing
to be secured after entering the Wheelchair.
 The User should never attempt to reach upwards or outwards for any object
which would require lifting their body weight off the wheelchair seat as this would
change the centre of gravity and could therefore affect the wheelchair stability.
 Leaning forwards by the User, in an attempt to reach something on the floor in
front of the wheelchair, can also create a serious instability situation and must not
be attempted.
 Excessive leaning sideways should also be avoided as this can affect the overall
lateral stability of the wheelchair, which could result in injury to the User, either by
tipping the wheelchair or becoming an obstacle to other people in congested
areas.
NOTES:
1. Do not hang heavy loads on the wheelchair backrest frames or push-handles
as this can seriously affect the rearward stability, especially when taking up
the drive on an incline (dynamic stability).
2. Correct use of the height adjustable rear Anti-Tippers, supplied as standard
with Invicta IPC-S and IPC-T models, is very important and these should be
positioned according to the environmental conditions where the wheelchair is
to be driven. (See page 35 relating to positioning Anti-Tippers)

Transportation of the Occupant, in a suitably adapted motor vehicle, when seated in
their wheelchair. Models IPC-S and IPC-T
Both Invicta models, IPC-S (Tested as
P17R) and IPC-T (Tested as P17RT) have
been successfully tested, in the forward
facing mode, to ISO 7176 part 19, on the
1st September 2010, at the Transport
Research Laboratory, Berkshire, UK.
The tests were carried out using fixed 4-
point wheelchair restraint systems and
fixed 3-point occupant restraint systems,
tested to ISO 10542 and supplied by
Q-Straint.
The front and rear wheelchair restraint tie-
down points, are clearly marked on the
chassis by standard Karabiner signs and
these are the only positions to be used in
transportation.
Under No circumstances should the wheelchair Lap or Pelvic Belt be used as the sole
method of occupant restraint.
The safe occupant weight limit for
transportation in the Invicta is 50Kg.
Although the Invicta Wheelchair “Crash
Tests” were carried out without using
Headrests, the use of these devices should
be optional, with the decision as to whether
it is necessary, being made by a suitably
qualified person following an individual risk
assessment.
The Wheelchair with Occupant should be positioned forward facing, centrally, over the tie-
down tracks located on the transporting vehicle floor. Both Parking Brakes should be applied
and the Drive Selector Lever set to the “Drive” (forward position), as indicated in Fig.5
The WTORS (wheelchair tie-down and occupant restraint system) should be connected and
used in accordance with the manufacturers recommendations, see Fig.4 as an example.
