Driving Up And Down Gradients; Use On Public Roads - Invacare TDX SP2 Series User Manual

Invacare® TDX SP2® Series
3. Check the position of the front wheels. They must be in driving
direction and at right angles to the obstacle.
4. Approach slowly and keep at a consistent speed until the rear
wheels have also passed over the obstacle.
Descending
The approach to descend an obstacle is the same as to ascend it with
the difference that you need not to stop before descending.
1. Descend the obstacle with medium speed.
When descending an obstacle too slowly it could happen
that the antitippers get stuck and lift the drive wheels
off the ground. A driving of the mobility device is then
no longer possible.
Ascending obstacles with a curb climber
1. Approach the obstacle or the curb slowly, head-on and at a
right angle.
2. Stop in the following position: 30 – 50 cm in front of the obstacle.
3. Check the position of the front wheels. They must be in driving
direction and at right angles to the obstacle.
4. Approach with full speed until the curb climber makes contact
with the obstacle. The impetus will lift both front wheels over
the obstacle.
5. Keep at a consistent speed until the rear wheels have also passed
over the obstacle.

CAUTION!
Risk of tipping over
– Only ever drive downhill at a maximum of 2/3 of the
top speed. Avoid sudden changes of direction or
abrupt braking when driving on slopes.
– Always return the backrest of your seat or the seat tilt
(if adjustable seat tilt is available) to an upright position
before ascending slopes. We recommend that you
position the seat backrest or the seat tilt slightly to
the rear before descending slopes.
– Always lower the lifter (if fitted) to its lowest position
before ascending or descending a slope.
– Never attempt to ascend or descend a slope on
slippery surfaces or where there is a risk of skidding
(such as wet pavement, ice etc).
– Avoid trying to get out of the vehicle on an incline
or a gradient.
– Always drive straight in the direction the road or path
you are on goes, rather than attempting to zigzag.
– Never attempt to turn around on an incline or a slope.
CAUTION!
Braking distance is much longer on a downhill
slope than on even terrain
– Never drive down a slope that exceeds the maximum
safe slope (refer to 11 Technical data, page 96).

6.7 Use on public roads

If you wish to use your mobility device on public roads and lighting is
required by national legislation, then your mobility device needs to
be fitted with an appropriate lighting system.
