Front Wheel Swivel Lock; Fig. 24 Caster Swivel Lock Engaged And Released - Otto Bock B400 Instructions For Use Manual

Operation
7.3 Front Wheel Swivel Lock
The wheelchair must be driven in totally straight line onto
ramps or into lifts. The B400 power wheelchair offers the
option of having the front wheels locked in the forward posi-
tion, thereby preventing the wheelchair from turning.
Engaging the front wheel swivel lock:
n Slightly rotate the folding lever on the front frame to the
side thus allowing it to jump out of its normal mid-
position.
n A bolt is released from the frame and engages in the
front caster fork as soon as the straight forward position
of the wheelchair is reached (see fig. 24, left photo).
Now the power wheelchair can drive straight forward or
backward.
Releasing the front wheel swivel lock:
n Turn the folding lever back to its mid-position where it will
disengage the bolt from the front caster fork.
n The lever engages into the centre of the front frame in an
unlocked position (see fig. 24, right photo).
