The figures below show the mechanism of the problem. Figures (a) and (b) show an
example of the correct condition, and (c) the symptom.
a) A new lubricant bar is installed. The hook gradually moves toward the brush as the
lubricant bar is consumed.
b) When reaching the point where the hook pushes down the arm, near end is
detected.
c) A used lubricant bar was installed and the hook on its assembly has pushed aside
the arm on the sensor. The arm is locked in this condition and the sensor
constantly detects near end status.
SOLUTION
As a preventive measure, do not install a used lubricant bar. Always replace with a new
one.
If the problem is observed:
Raise the arm of the sensor to correct its position using a flathead screwdriver or a similar
tool. The arm should sit straight, not slanted.
Make sure the arms on both front and rear sides are not caught in the sponge.
