6.12.5 Locking the steering casters
The power wheelchair may be equipped with a steering
caster lock.
It locks the steering casters in the forward direction so turn
ing is no longer possible. Having the power wheelchair drive
in a perfectly straight line increases safety when driving on
ramps or using elevators.

2) Turn the steering caster lock so that the black plastic
arm can be positioned next to the spacer (see Fig. 35,
item 2). Let go of the steering caster lock.
→ The bolt of the steering caster lock (see Fig. 35, item 3)
engages with the front fork when the power wheelchair
is facing straight ahead.
→ The steering casters are locked. The power wheelchair
drives straight in both forward and reverse.
Disengaging the steering caster lock
1) Pull the steering caster lock up (see Fig. 35, item 1).
2) Turn the steering caster lock so that the black plastic
arm can be positioned on the spacer (see Fig. 35, item
