Driving Up And Down Gradients - Invacare TDX SP2 User Manual

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.
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.
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. Driving the mobility
device is then no longer possible.

6.6 Driving up and down gradients

For information concerning the maximum safe slope, refer
to 11 Technical Data, page 105 .
1578997-E
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
rated slope (refer to 11 Technical Data, page
105 ).
