Obstacles and thresholds
Driving obstacles should be done very carefully. When driving an obstacle which is too high the Navigatoe
might get stuck. For maximum ground clearance please see the chapter ‘Technical data’.
Picture 35
Driving up thresholds:
drive towards the threshold until the front wheel is approximately 20-50 cm
before the threshold. Now carefully drive forward and approach the threshold. As soon as the front
wheel is on the threshold you can slowly drive further until the rear wheels are also on or over the
threshold (picture 35). If this does not succeed or very difficult, please choose another route.
Driving off thresholds:
drive to the threshold until the front wheel is before it. Drive off the threshold
carefully and with low speed.
Brakes
Braking can be done in different ways:
•
you can slowly move the gas lever into the neutral position, to make the Navigator slow down
easily
•
you can just let the gas lever go, so the Navigator will come to a full stop
•
the Navigator is also fitted with a disk brake rear with the lever on the tiller. This may be used
on eventual emergency stops
If driving down a hill the Navigator might drive faster than the maximum speed possible. In this case the
control unit will slow the Navigator down to reach the programmed maximum speed.
If the gas lever of the Navigator is in neutral position the scooter is braked. The motor brake power is
enough to stop the scooter and keep on its place on the maximum possible incline angle (12 degrees).
At rain, snow or other slippery road conditions, please brake gently to provide sliding danger.
Battery safety
When driving on low or empty batteries, to be seen on your battery indicator, the battery safety feature
will be engaged. This provides battery damage through deep decharge. The engagement of this feature
can be noticed by the decreasing maximum speed. Drive as little as possible in this condition. After thy
system being engaged the batteries should be charged as soon as possible.
