Contents SPECIFICATIONS OF THE LIGHT ASSIST 2.1
COMPONENTS
Comprises two electric motors tted with the transmission,
mechanisms making the connection between the wheelchair
interface and nally the battery slider.
The Light Assist 2.1 consists of several components:
THE MOTOR TUBE
Comprising a 12 Ah LITHIUM BATTERY mounted on
a support rack that enables installation and automatic
connection to the motor subassembly.
The power add-on is supplied charged. Unless the battery
is transported by air, when it is supplied uncharged. In
this case, before using your equipment for the rst time,
you have to charge the battery for 8 hours.
* Battery life can vary depending on the temperature, the person’s weight and the type of ground.

CONTROL HANDLES
The wheelchair tted with a power add-on keeps its initial balance. But the power of the motors, if
badly controlled on slopes, can make the wheelchair tip over. The anti-tip fulls its role effectively
while allowing obstacles to be crossed. It must always be tted (small wheel downwards). This has been
adjusted by your installer to guarantee safe driving.
All the travel functions of the Light Assist 2.1 are operated by the control handles. Two
handles are supplied with the power add-on:
• one throttle handle
• one static handle
The handles (throttle and static) are positioned to right or left on the rear handles of the
wheelchair and are locked in place.
Benoit Systemes waives all liability if an accident occurs while the anti-tip is not tted.

Before making your rst journey, you should familiarise yourself with operation of the electric vehicle
and all the accessories. Take your time to test all the functions and driving modes.
PROPERLY SEATED = SAFE DRIVING
Before each journey, check that:
• The user is posioned safely in their wheelchair (wearing a seatbelt, if necessary).
• The baery suciently charged for the journey you’re planning to make.
• The safety an-p is inserted into the rear handle. Check the mounng direcon (small wheel
downwards) and that the locking pin is securely ed.
OPERATE USING THESE CONTROL HANDLES
Press the ‘Start/Stop’ button to set the Light Assist 2.1 in motion.
Turn the handle to go forwards or backwards depending on the position of the Forwards/Backwards
button. If you wish, adjust your speed using the speed limiter button by rotating it slowly until the desired
speed is reached.
For a pleasant journey, adjust the speed to suit your own pace. Release the throttle handle to stop the
Light Assist 2.1.

SAFETY RECOMMENDATIONS ABOUT ELECTRO-
MAGNETIC COMPATIBILITY
Electromagnetic elds, such as radio and television
transmitters, radio devices and mobile telephones
produce them, and may have an inuence on the
operation of the vehicle. The electronic device
used in this device can also cause weak electro-
magnetic disturbances, however these are below
the legal limit. Therefore please consider the fol-
lowing comments:
WARNING
Risk of incorrect operation following electro-
magnetic emissions
• Do not use a portable transmitter nor com-
munication devices (radio devices or mobile
telephones) or, as applicable, to not use them
while the electric vehicle is in use.
• Avoid going near powerful radio or television
transmitters.
• If your vehicle should start moving by itself, or
if the brakes happen to be released, turn the
equipment off.
• Adding electrical or other accessories or mo-
difying the equipment risks making it subject
to electromagnetic emissions/faults. Taken
into account the fact that there is no really
safe method to determine the effect of such
modications on the resistance to interfe-
rence.
• Report to the producer all undesirable move-
ments of the vehicle that occur, even the elec-
tric brakes being released.
SAFETY INFORMATION ABOUT INSTALLATION
WARNING
Risk of damage to the equipment or serious, even

• Turn the control handle until the desired
speed is reached. When starting off, use the
slowest speed and increase the speed slowly
to reach your walking pace. The speed should
not be faster than the walking speed of the
person pushing the wheelchair.
• Always ensure you can be seen from afar, es-
pecially if you use your motorised wheelchair
at night.
• Pay close attention to trafc on the road.
• Don’t forget that car or lorry drivers do not
expect to see a manual wheelchair running at
a speed greater than that achieved by manual
propulsion. If there is the least danger, don’t
take the risk of crossing the road.
• Remember that the motorised vehicle can
stop operating suddenly if you completely
discharge the battery:
• we recommend using a lap seat belt when you
use the power add-on.
• we recommend using a lap seat belt when you
use the power add-on.
• Never approach steps or ditches at maximum
speed.
• Turn the Light Assist 2.1 off when you stop or
are waiting in front of potential sources of
danger and take your hands off the control
handle
Any malfunction of the control unit is liable to re-
sult in unexpected/erratic movements leading to
damage to the equipment or serious, even fatal,
injuries.
• If an unexpected/erratic movement occurs,
stop using the motorised vehicle immediately
and contact a qualied technician.
• It is important that the joystick is replaced if it
is damaged or weakened, as this could damage
the control unit.
WARNING
Risk of injury if the motorised vehicle tips over.
• Refer to the technical specications (maxi-
mum safe slope)
• As far as possible, avoid driving on slippery,
icy or oily surfaces when there is a risk of lo-
sing control of the vehicle. If you cannot avoid
travelling over such surfaces, drive slowly and
with the greatest care.
• Keep away from the kerb when travelling on
pavements.
• Ensure that there are no objects in your
path likely to damage the mechanism of your
vehicle.
• Cross the kerbs of pavements going forwar-
ds or backwards. When you cross obstacles,
always stay within the maximum obstacle
height (refer to the Technical Specications
section).
• Never try to go down a series of steps with
your motorised vehicle.
• Avoid making sudden movements of the
control unit or sudden changes of direction
while the motorised vehicle is moving.
• Never use the motorised vehicle to transport
several people.
• Do not exceed the maximum total permitted
load (refer to the Technical Specications sec-
tion).
• Remember that the motorised vehicle brakes
or accelerates when you change the speed of
travel while the vehicle is moving.
• The anti-tipper device must be used.
• Turn the Light Assist 2.1 off immediately when
you no longer need it to avoid unintentional-
ly initiating a driving force by touching the
control handle.
DANGERS AND DANGEROUS SITUATIONS
• When taking corners or turning round while
going up or down, only perform these ma-
noeuvres carefully and slowly.
• When you are crossing main roads, crossroads
and level crossings, take the greatest care. Ne-
ver cross parallel to the rails on the road and
level crossings as the wheels could get trap-
ped.
• Be very careful when going on ramps and
vehicle lifting devices. The Light Assist 2.1
must be turned off during the lifting or lowe-
ring process of a ramp or a lifting device. The
control handle must not be operated. In ad-
dition, the wheelchair’s handbrake must be
applied to avoid any unintentional movement.
WARNING
Risk of injury if you collide with an obstacle while
passing through narrow passageways such as
doors and entrances.
• Pass through narrow passageways at the
slowest speed of travel and with the greatest
care.
