2.3. Safety requirements for the operation of the wheelchair
Risk of accident or injury due to defective safety devices. Before each
use, the user has to check operative condition of the Product, especially
the safety device.
Operation of the Product is only possible if all safety devices, such as an
automatic brake, are functional. Defective brakes can cause serious
injuries with fatal outcome.
Risk of accidents due to operating the wheelchair without experience.
Movement in the wheelchair without sufficient experience can lead to
falls and other dangerous situations. Before using the Product, it is
necessary to practice on a flat and spacious ground.
Risk of accidents due to uncontrolled movement of the Product.
Faults arising during the operation of the Product can cause uncontrolled
movements. In this case, you should immediately contact the
Manufacturer. If you find faults and problems with the product, it is
necessary to stop using it, as this can be dangerous both for the user and
for the people around.
Risk of accident or injury due to improper sit in the chair or leave it.
Turn off the Product when sit in the chair or leave it. The footrests can
only be used to support the legs. Do not stand on the footrests!
Overload damage. The maximum passenger weight is limited to the
values given in the technical specifications of the Product (see 3,
table. 1).
Tire damage. High air pressure in tires can damage them. Do not exceed
the recommended tire pressure (see 12).
The system will generate an error of the speed sensor if you start to
move in idle mode of geared motors (see 7.5).
Damage caused by overheating of the wheelchair or exposure to low
temperatures. The Product functions normally only in a temperature
range of -15 °C to +40 °C. Do not use the wheelchair outside this
temperature range.
Risk of overturning Products using lifting platforms. Turn off the
Product when using lifting platforms or lifts and when traveling on buses
or trains.

After each emergency stop, turn off and turn on the Product control
device. In case of errors, the system informs with a light code (see 11,
table 6) or shows a fault message on the display, stopping the execution
of uncontrolled functions. If, after restarting the control system, the
Product displays an error again, the user can unlock the electromagnetic
brakes of the wheelchair to transfer it in pushing mode (by attendant
person). If it is not possible to ensure the movement of the wheelchair
by muscular strength, or to ask for help from others, the Product can be
controlled in "manual mode" (the control system must not be de-
energized). Driving in "manual mode" ignores the sensor values and
allows you to reach your destination, despite the blocking of the motors.
However, certain faults may damage the Product.Evaluate the risks and
use this mode only in situations where no alternative solutions to
problems. After the appearance of such faults, contact the Manufacturer
for specialist consultation.
Risk of accident or injury due to incorrect lifting of the wheelchair.
Attendant persons should only lift the wheelchair using special handles
(fig. 2.1) or the front frame beam. Do not lift the wheelchair by the
footrest or armrest!

Risk of injury if the wheelchair overturning while driving.
The Product can overcome slopes with an angle less than 15° (24 %) in
the "On wheels" mode (see fig. 2.5). Moving at angle of more than 15°
(24 %) is not allowed!
The Product is equipped with a track platform for climbing stairs with
angle of up to 35°, maximum step height —180 mm. The Product is not
intended for use on spiral stairs.
Risk of accidents due to the Product overturning while in movement.
When the Product moves slope, the speed should be reduced (for
example, put into 1st gear). On descent and climbs, it is forbidden to
overcome obstacles, leave and sit in a chair. Overcoming obstacles,
descents and climbs is allowed only with the vertical position of the
backrest.
Overcoming obstacles such as steps and curbs is possible only on tracks.
In this case, the obstacle should be perpendicular to the direction of
movement.
The movement on the stairs can be performed only by orienting the
Product in front of the descent (fig. 2.6). Descending the stairs only
forward. Climb stairs only backwards. In "on tracks" mode, the system
will automatically maintain the horizontal position of the chair by tilting
it back.
Driving on ramps on wheels is possible only at an inclination angle of
no more than 15 degrees. If this angle is exceeded, the wheelchair
should be moved on the tracks with its back to the incline. For stability
when lifting, you can tilt the chair position within 14 degrees.
