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 direc
tion, 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.46, left).
→ The steering casters are locked. The power wheelchair
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.46, right).
→ The steering casters are unlocked and can swivel freely
again.
