6.12.5 Locking the steering casters

The power wheelchair may be equipped with a steering
caster lock.
These serve to lock the steering casters in the forward dir­
ection, so that turning is no longer possible. Having the
power wheelchair drive in a perfectly straight line increases
safety when driving on ramps or using elevators.
Engaging the steering caster lock
► Push the folding lever on the front of the frame to the
side a bit until it disengages from the centre position.

→ The bolt at the bottom edge of the front frame extends
and engages with the front fork as soon as the power
wheelchair faces straight ahead (see Fig. 41, left).

drives straight in both forward and reverse.
Disengaging the steering caster lock
► Turn the folding lever to the middle position until it
engages.
→ The lever is in the unlocked position (see Fig. 41, right).
→ The steering casters are unlocked and can swivel
freely again.
