The front collision sensor is composed of a magnet and an
associated sensor circuit board. The magnet is tted in the
holder of the charging strips which is placed underneath

protects against ingress of dirt between the top cover
and the body. The magnet must be tted correctly if the
collision sensor is to work. If the collision sensor does not
work, replace the charging strip holder. See 5.5 Replacing
the charging strips on page 64.
To replace the front collision sensor circuit board:
1. Disassemble the body. See 5.2.1 Disassembling
the body on page 59.
2. Disassemble the chassis. See 5.2.2
