Description and Intended Use8.
The YACK N 910 is an aid for the disabled that allows persons with reduced motor
capacity to overcome architectural barriers with the assistance of an operator.
It is a Class I medical device as defined by Annex IX of Directive 93/42/EEC, and is
constructed in conformity with Italian and international law on medical devices and
aids for the disabled and officially published in the Repertorio dei Dispositivi Medici
(list of medical devices available in Italy) kept by the Ministry of Health.
The Stair climber is a mobile instrument that can be transported and used anywhere
and on all types of stairs, ensuring complete freedom of movement and the passenger’s
comfort and reducing the strain on the assisting personnel to a minimum.
The stair climber is indicated for wheelchair-bound persons who need to be moved
to different floors within a building with the assistance of a caregiver. It consists
of a metal structure driven by a DC motor powered by a removable and interchangeable
rechargeable battery. It is manoeuvred using a telescopic steering column with control
buttons and is provided with interfaces for monitoring the battery and controlling its
speed.
Since it has wheels, the stair climber can tackle straight, curved and spiral stairs and
wedge-shaped steps and needs reduced manoeuvring space.
The control electronics have both continuous- and single-cycle modes. In the latter
mode, continuous pressure on the start button generates only a single climbing cycle
(corresponding to one step).
Transport is facilitated by the possibility of disengaging the “guide” steering column
from the body of the machine, the rotation of the handle and the presence
of convenient grips for handling.
The N 910 stair climber can be configured in the following three versions:
- N 911 version with seat;
- N 912 version with a mechanism for hooking a wheelchair complete with plates;
- N 913 version with a hooking mechanism complete with customized brackets
for hooking the wheelchair;
The parts and accessories of all three YACK versions can be totally disassembled
allowing them to be easily handled and stored. All the parts have minimal dimensions,
are easy to transport and can be stored in small spaces.
The stair climber is exclusively designed for the transport of persons as indicated
in this document.
It must be used within the limits and according to the methods explicitly described
by the manufacturer in this manual. The manufacturer will not be liable for personal
injury or property damage caused by use by untrained personnel, unauthorized
modifications or repairs, the use of unauthorized spare parts, exceptional events
or a total or partial failure to follow the instructions in this manual, which must
accompany the product if sold to third parties.

Operator electronic panel
The electronic control interface is activated with the insertion of the jack (1).
The LED (2) turns green if the stair climber is ready to start; otherwise, it turns red to
indicate the presence of anomalies due to an unsuitable climbing/descending inclination
(only for versions with electronic inclinometer enabled) and the operation
of the machine is inhibited.
The status of the battery is indicated by LEDs (3) as follows:
1st level: maximum charge, all on (from top to bottom)
3 green, 3 yellow, 2 red;
2nd level: the first two green LEDs turn off, 1 green, 3 yellow and 2 red are lit;
3rd level: the last green and first yellow LEDs turn off, 2 yellows and 2 red are lit;
4th level: the second yellow LED turns off, 1 yellow and 2 red are lit;
5th level: the last yellow turns off, 2 red are lit and the buzzer sounds intermittently;
6th level: the machine is locked.

The LEDs (4) indicate the speed selected from the four available.
To increase the speed, press the “+” button (5a) and to decrease it,
press the “-” button (5b).
The Stair climber can climb and descend at 4 different speeds in intervals of 10%
of the maximum speed of 5 seconds/step (12 steps/minute).
At power-on, the machine’s speed is automatically set at 100%.
The LEDs (4) also signal an overload problem.
If the weight carried exceeds the maximum allowed, after moving a few centimetres,
the machine detects that the weight limit has been exceeded and immediately
returns to the rest position. The six speed LEDs will flash and the buzzer will sound
intermittently to signal the problem. The stair climber is, thus, inhibited until it is reset
by removing and reinserting the start jack.
The hold-pressed buttons (6) located on the handle are the actual operating buttons.
When the operator presses the button away from himself, the stair climber descends
the stairs ahead of the operator and when the operator presses the button towards
himself, the stair climber climbs the stairs towards the operator’s back.
Climbing/descending can take place one cycle/step at a time (LED (8) off ) or with a
continuous, cyclical lifting movement for the entire time that the button (6) (LED (8) on)
is pressed. The mode is selected with button (7).

Transport, handling and unpacking11.
Handling and Unpacking
To protect the operator from
hazards deriving from the manual handling
of loads (Directive 269/90/EEC),
consult the section, Technical Characteristics,
which lists the weights of the single parts.
The person assigned to unpacking must be
informed of the risks of these operations.
This section lists the basic operations
for correct handling.
To lift the load correctly without risking harm to your spinal column, you must:
1 - Keep your back straight
2 - Keep your trunk erect
3 - Your body should be crouched
4 - The weight lifted must be kept as close to the body as possible
5 - For lifting loads that weigh more than 25 kg
(if the operator is female, the load limit is 15 kg)
ask others for help or use suitable equipment
6 - Do not store the products above
shoulder height
7 - Bring the package to a suitable
area for unpacking and assemble
the two parts of the machine.
8 - Open the packing without
using sharp or pointed objects
that could damage the contents.
It is a good idea to keep the original packing materials for future reshipment of the
device (such as to the Service Department) because they will ensure safe transport.
