8.4 front Wheel Swivel Lock
The wheelchair must be driven in totally straight line onto
ramps or into lifts. The B500 power wheelchair also
offers the option of having the front wheels locked in the
forward position, thereby preventing the wheelchair from
turning.
Engaging the front wheel swivel lock:
r Slightly rotate the folding lever on the front frame to
the side thus allowing it to jump out of its normal mid-
position.
B500 | B500-S
r A bolt is released from the frame and engages in the
front caster fork as soon as the straight forward posi-
tion of the wheelchair is reached (see fig. 31, left
photo).
Now the power wheelchair can drive straight forward or
backward.
