1. SAFETY RULES
1.1 General Information
Applies to all wheelchairs
Driving settings should only be adjusted and/or modified by a
health care professional or an authorized service technician.
Improper driving setting adjustments couldbe hazardous to the
occupant.
1.1.1 BEFORE YOU HIT THE ROAD
CHECK:
•Parking brakes engaged;
•Anti-tip device installed;
•Sufficient tire pressure;
•Stable seating position;
•Removable and/or retractable foot support and arm support locked;
•Elevating lower leg support assembly is lowered;
•Adjusted pelvic positioning belt;
•Tilt mechanism and reclining back support in driving position;
•Make sure that nothing interferes with the wheels (scarf, umbrella, coat hanging
from the back support, etc.) and that no heavy objects are hanging from the back
support;
•Make sure that the battery is sufficiently charged and that the cables of the control box
and parking light switch are correctly positioned to prevent wheel lock or interference
with the environment;
•If you own an Oasis, make sure that the rubberprotector under the joystick tip is in good
condition (if not, have it repaired immediately).
Never allow a child to play with or on the wheelchair, whether
or not the occupant is sitting in it.
If you intend to leave the unit in one place for a long period of
time, turn the power off to reduce the risk of accidental power-
up.

1.1.2 GETTING AROUND IN A WHEELCHAIR
•Always use the pelvic positioning belt and adjust it properly;
•When faced with an obstacle, stop, and move forward gradually;
•Avoid slippery and uneven surfaces;
•Avoid sudden and abrupt turns;
•If unsure of surface conditions, bypass the area or avoid venturing out;
•If weather conditions are extreme or change abruptly, find shelter as soon as possible;
•Always make sure you are visible;
•Do not pull a trailer or carry passengers;
•To maintain good balance, ensure proper distribution of objects on the wheelchair and
avoid carrying heavy objects;
•Do not approach slopes. If it is unavoidable, make sure you never climb or
descend diagonally and always face forward. For manual and tilt wheelchairs, it
is strongly recommended to approach slopes with an assistant, regardless of
angle.
The following additional considerations apply to Oasis electrically powered
wheelchairs:
•Avoid any impacts to the control box or joystick;
•Do not change direction abruptly at high speeds;
•Do not drive on expressways or high traffic lanes;
•Do not drive in extreme weather conditions (i.e., storms);
•When traveling outside at night, make sure you are visible to others;
•Operate the joystick gently when starting on a hill to avoid tipping backwards;
•Do not turn around on an incline;
•Reduce your speed in tight or crowded areas;
•Reduce your speed in crowds and use your horn to signal your presence;
•The Oasis can climb 50 mm obstacles; However, it is strongly recommended to avoid
thresholds over 38 mm (1 ½ in.) as this could, depending on surface conditions, put
your stability at risk;
•Use elevators to move between floors;
•Do not move around without your feet on the foot supports;
•Do not ride an escalator with your wheelchair;
•Keep your hands away from the wheels when your electrically powered wheelchair is
in motion;

1 SAFETY RULES

Inc. All rights reserved
•The Oasis wheelchair can negotiate slopes at low speed, with a maximum incline of
10°, external or internal, and a length of at least 3 metres, alone or with an assistant.
The assistant must always be at the back of the wheelchair, whether ascending or
descending, and should hold the back support posts;
•Do not make sudden stops and starts;
•Do not let the wheelchair gain too much speed when going downhill;
•Stop if you feel you are losing control;
•Restart slowly without letting the wheelchair accelerate;
•Climb and descend slopes in a straight line directly along the slope’s axis; This greatly
reduces the risk of tipping or falling;
•The wheelchair will remain stable and under controlled trajectory if the above conditions
are met. Ascending or descending an incline with an electrically powered wheelchair is
possible, if the consulting health care professional is satisfied that the user understands
the limitations of the wheelchair and is capable of driving under these conditions.
Comply with the above conditions to ensure the wheelchair’s
stability and ability to control the desired trajectory.
Ascending or descending an incline, either independently or
with an assistant, is possible if the consulting or prescribing
health care professional is satisfied that the occupant has the
physical and cognitive skills to do so.
1.1.3 TRANSFERRING
•Fold down the foot supports;
•It is recommended that leg support assemblies be removed before transferring;
•Always apply the brakes before a transfer or before sitting in the wheelchair;
•Never lean forward or backward to reach an object;
•Position yourself sideways to the object to be reached, as close as possible;
•Use the techniques learned from your health care professional to make the transfer;
•Do not sit on the back support if it is reclined;
•Never stand on the foot supports;
•Never sit or lean directly on the arm supports;
•Always switch off the control box before transferring or transporting. Retract the control
box if necessary.
1.1.4 MISCELLANEOUS HANDLING
Do not charge the batteries in your bedroom. While charging,
batteries may release harmful gases.

1 SAFETY RULES

Inc. All rights reserved
•Never submerge your wheelchair or leave it in the rain for a prolonged period;
•Do not store your wheelchair in a damp or very cold place (this could cause serious
damage);
•If the occupant remains seated in a wheelchair while travelling in a road vehicle
designed for transporting disabled persons, make sure that the occupant, driver and the
vehicle owner respect all legislative, regulatory, policy, guideline and standard
requirements, instructions and recommendations of all competent authorities;
•When approaching an inclined surface in freewheel mode, the assistant should always
be toward the bottom of the incline relative to the wheelchair;
•Do not attempt to lift or move the wheelchair by moving parts such as arm supports, leg
support assemblies, seat, control box, or cover. Use only non-removable, solid frame
components.
The following items should be considered:
•Do not let children play near the wheelchair unattended when it is charging;
•Do not modify the 110 V AC connection of the battery charger;
•Do not modify the 24V DC connection to the wheelchair;
•Never use extension cords to charge your electrically powered wheelchair;
•Since your wheelchair is equipped with a built-in charger, never plug a second charger
into the control box or modified control interface;
•Never connect electrical accessories to your wheelchair other than those authorized by
;
•Never modify the electrical circuit of the wheelchair;
•Immediately replace any damaged power cables;
•Use only sealed AGM or gel batteries;
•Never touch both battery terminals with a metal tool simultaneously. Contact between
the two terminals can cause burns, explosion, or electric shock;
•Only use batteries with similar characteristics. Never pair an old battery with a new one;
•Wear protective eyewear and gloves when handling batteries, as the terminals contain
lead. Wash your hands after handling batteries, as they contain corrosive materials;
•Never recharge batteries in your bedroom;
•Only use charger models recommended by .
1.1.5 COMPONENT CLEANING AND MAINTENANCE
To disinfect the wheelchair, first remove all accessories that require special treatment and those
that cannot be treated:

Inc. All rights reserved
Special treatment: All upholstery from which foam cannot be removed (back support, lower leg
support). Disinfection by hand. Using a cleaner,first wipe with a cloth, then apply a disinfectant,
wait the required time, and wipe off.
Not treatable: Electronic components (batteries, control box, etc.).
Using a soft cloth, clean the control box and joystick as soon as possible if they become dirty.
Fabric washing: remove foam and machine wash the cover in warm water with mild soap.
Hang to dry. Do not use alcohol-based detergents or thinners.
For other components, pre-moistened alcohol and/or quaternary ammonium wipes are
recommended.
1.2 About electromagnetic energy
All electronic devices that transmit information at a distance usually emit radio waves into
the environment. These radio waves are called "electromagnetic energy". This
electromagnetic energy may affect the proper functioning of an electronic device. This is
called "electromagnetic interference". Although the electrically powered wheelchair
complies with BNQ 6645-001 (2019) standard for electromagnetic testing, any electrically
powered wheelchair is susceptible to electromagnetic interference. As the intensity of the
energy increases, so does the risk of malfunction.
To avoid electromagnetic interference, please read and follow
the warnings below before using your chair for
the first time.
1.2.1 WARNINGS
Waves emitted by:
•Radio and television stations;
•Ham radio equipment;
•Radio transmitters/receivers;
•Cell phones;
•All Bluetooth and Wi-Fi enabled electronic devices;
1.2.2 USE OF TRANSMITTERS AND RECEIVERS
•Avoid proximity to these electromagnetic emission sources.
•Turn the control box off before using a cell phone or a CB radio.
•Adding electrical accessories and/or making certain electrical modifications to the
wheelchair will alter its immunity to electromagnetic emissions.
