7. Intended use / intended user
The Morgan M Sling (MGNM-SLN) powered wheelchair is meant to provide
mobility to persons who are not able to walk, stand or use a manual
wheelchair, but who are very well able to control and use the interface of a
powered wheelchair. The wheelchair is designed for a maximum user weight
of 136 kg.
It is strongly suggested to have the use of the wheelchair evaluated by a
trained doctor, therapist or other qualified and trained staff.
This wheelchair is not suitable for persons who do not have the cognitive skills
to drive a powered wheelchair by themselves. Also, it is not suitable for
visually impaired persons.
The expected service life of the product is five years, presuming that the
product is used daily in accordance with the safety operation instructions,
inspection and maintenance instructions, and intended use, which described in
this manual.
8. Intended environment
The Morgan M Sling (MGNM-SLN) powered wheelchair is not restricted to
only indoor or only outdoor use. Because the driving wheels are placed in the
middle, the wheelchair is extremely maneuverable and is able to cope with
many terrain differences. This, combined with the compact size of the product
and the excellent speed range and battery capacity, making the wheelchair
suitable for both indoor and outdoor use.
It is allowed to use the wheelchair in different weather conditions. It can be
used at temperatures of -25 degrees up to maximum 55 degrees Celsius and
the charger operate temperatures is 0 up to 40 degrees Celsius.
However, it must be noticed that metal or plastic surfaces of the wheelchair
can become very hot when exposed to direct sun for longer time.
Because of the harmful combination of saltwater and sand, it is advised not to
use the wheelchair on beaches. We advise to clean the wheelchair after
having been in contact with sand and/or saltwater as described in the
paragraph “cleaning”.

9. Tire pressure
The Morgan M Sling (MGNM-SLN) uses solid or air-filled tires in the front and
middle and solid tires in the rear. The choice of having solid or air-filled tires is
made by the user during the ordering of the wheelchair. In order to prevent tire
damage and to preserve the performance of the wheelchair, the tire pressure
must be checked at least on a monthly basis. The tire pressure should be:
Front air-filled tires (small): max. 275 Kpa / 40 PSI / 2.8 bar
Middle air-filled tires (large): max. 240 Kpa / 35 PSI / 2.4 bar
10. The wheelchair
10.1. Chassis
The chassis is the base of the wheelchair. It contains wheels, drive motors,
batteries and electronics. The steel parts of the chassis are electrolytic
anodized and powder coated to ensure a long life without corrosion.
Each of the middle wheels is propelled by a powerful drive motor. These
motors also take care for the steering of the wheelchair. With this system it is
possible to turn on the spot. This makes the wheelchair optimal for indoor use.

10
10.1.1 Chassis suspension
The chassis has independent suspension on each of the six wheels. The
stiffness can be adjusted to your personal requirements.
10.1.2 Lights and reflectors (Optional)
The chassis has very strong and bright LED lights to make sure you can have
a safe drive in the dark. The red reflectors in the rear also make you visible for
other people as well. The lights fulfill the European requirements. The
additional LED indicators give our environment clear information in which
direction you want to go.

10.1.3 Transport fixation loops
The fixation loops are marked with this sign:
Further information about transportation of the wheelchair will find
in chapter "transportation".
10.1.4 Battery compartments
The batteries are mounted as low as possible in the center into the chassis, to
provide an optimal center point of gravity. This results in a maximum stability
of the wheelchair. The compartment can hold maintenance-free batteries up to
80Ah. For the specification of the batteries see the chapter technical
specifications.
The maintenance-free batteries can be reached from the front and rear sides.
They can be replaced whilst the user is still in the wheelchair.
For more details of changing the batteries, please check the paragraph
“battery replacement”.

Front battery box
When pulling the battery out of the box, do mind to not overstretch the
cables. This might lead to technical failure.
Before reconnecting the battery, read the wiring instructions on the inside
of the battery cover.

13
10.1.5 Main fuse
The chassis contains a circuit breaker which is located at the front of the
chassis. The circuit breaker protects the whole electrical system of the
wheelchair. This circuit breaker will only blow if there is a serious problem on
the wheelchair.
Position of circuit breaker
This situation happens typically when the wheelchair is climbing up a hill that
is steeper than what is restricted. Should the circuit breaker pop-up, you need
to eliminate the cause first. And then, press down the circuit breaker. You will
be able to drive again.
If the circuit breaker has blown, do not replace it immediately. First
contact your local supplier to have the wheelchair checked.
Only use original circuit breaker as replacement. Using other circuit
breaker might lead to material damage to the wheelchair.

10.2 Seat
The Sling Seat can be adjusted in seat depth, seat-to-
back angle, footrest length and hanger position, and
armrest height. It can be up-graded into manual
recline, power recline or power tilt. The seat pan is flat
so other seating cushion can be fitted on to the seat as
well.
10.2.1 Upholstered seat cushion
The Sling Seat upholstered seat cushion is available in different sizes to
provide optimal seating comfort and support to the user. The cloth is air mesh.
The seat cushion is well fixed with Velcro on to the seat pan to prevent it from
sliding.
10.2.2 Seat tilt (Optional)
The seat tilt can be used to release pressure. The tilting angle is from 0 to 21°.
The tilting function can also be used when driving down a slope for
compensating the negative seat angle. This provides a more stable seat
position and safe driving.
Max 21°

15
If the tilt is activated over a certain angle, the driving speed will be reduced.
This is to reduce the risk of danger whilst driving at high speed.
10.2.3 Upholstered backrest
The Sling Seat upholstered backrest is available in different sizes to provide
optimal seating comfort and support to the user. The cloth is breathable fabric.
The upholstered backrest is well fixed with Velcro on to the bottom backrest
upholstery to prevent it from sliding.
10.2.4 Backrest
Angle adjustable backrest
The Sling Seat backrest angle can be set from 91°/ 94°/ 97°/ 100°/ 103°/
106°. By adjusting the position of knobs and nuts, you can set the backrest to
the desired angle.
Always drive carefully on slopes. The angle of the slope has great
influence on the total stability of the wheelchair.
When tilting, always check if there are no obstructions close to the
wheelchair. Especially in the front or rear of the wheelchair.
When tilting, the wheelchair will get longer. This has influence on the
driving characteristics of the wheelchair. Make sure there is enough
space to drive.
