Driving Up And Down Gradients - Invacare TDX SP2 Series User Manual

Invacare® TDX® SP2 Series
3. Check position of front wheels. They must be in driving
direction and at right angles to obstacle.
4. Approach slowly and keep at consistent speed until rear
wheels have also passed over obstacle.
Ascending Obstacles With Curb Climber
1. Approach obstacle or curb slowly, head-on and at right
angle.
2. Stop in following position: 30 – 50 cm in front of
obstacle.
3. Check position of front wheels. They must be in driving
direction and at right angles to obstacle.
4. Approach with full speed until curb climber makes
contact with obstacle. Impetus will lift both front
wheels over obstacle.
5. Keep at consistent speed until rear wheels have also
passed over 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 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.

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 mobility device
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
116 ).
