General safety precautions
The Navigator is designed to be safe in use. This can be noticed on the scooter directly in the below
features:
•When charging the scooter it cannot be driven electrically
•At too high temperature of the engine or controller unit (Dynamic Rhino) the Navigator will drive
at half power
•With the freewheel function engaged the scooter cannot be driven electrically
•If the control lever is in neutral position the scooter cannot be driven.
•Scooter parts where might be body parts clamped between are fully covered
The Navigator is meant to be used by one person. Placing a second person on the scooter is not allowed.
The driving characteristics will be influenced badly by this and the Navigator will damage.
Inside the control unit (Dynamic Rhino) is a function build who prevents deep de charge of the
batteries. The control unit reduces the speed eminently.
Please make sure when driving the scooter and performing small maintenance to the Navigator there
can be no fingers injured in the space between the covers and the wheels.
Driving inclines
A very safe control feature when driving inclines is the following: if the Navigator is able to drive an
incline, the incline can also be descent with reduced speed. Always drive a steep incline up first and
make sure the Navigator is not too heavily loaded.
Turning the Navigator on an incline is not recommended. The scooter can easily tip over.
Never drive from a pavement or incline diagonal. The scooter may tip over. Always drive off a
pavement or incline at low speed.
In areas with pedestrians it is recommended to adjust the maximum speed to a lower standard for your
and other persons safety.
Transport
Transporting the Navigator inside a vehicle can be done by making the scooter as small as possible. In
this case, you dismount the chair and fold the tiller down. Always check if the scooter is not in
freewheel mode and fixate is firmly to the floor.
It is recommended to not sit in the scooter during transport. The scooter should always be lifted by two
persons, one at the front (front bumper) and one at the back of the scooter (rear bumper). Van Os
Medical accepts no responsibility for any eventual consequences.
Freewheel mode
On freewheel engagement the brakes of the Navigator are not working. By disengaging the freewheel
lever the brakes will be in work again. Look at page 17 for further freewheel explanation.
Never us the freewheel mode when standing on an incline. This may cause the scooter drive by itself.
Electro Magnetic Compatibility
A couple of uropean standards have been set in the field of electro magnetic interference on electric
devices. The Navigator complies to these demands. In an extreme case the Navigator might be sensitive
to very powerful transmitters. This may cause unexplainable faults. In this case you best turn to your
dealer.
When using transmitters nearby the Navigator, we recommend to first shut down the scooter before
using a device.

Examples of transmitters can be mobile phones, walkie talkies or a 27 MC transmitter. The Navigator
itself also transmits electric waves. These are within the applying standards. There might be, however,
certain unintended events, like a shop alarm going off.
Fixation belt optional)
An optional fixtion belt can be mounted to fix the seat position (picture 1). The two parts of the belt can
be mounted below the seat with screws. The screws fixate the belt to the ground plate of the seat. By
use of a click buckle the belt can be fixated.

may not be used as a safety belt.
