12-2. Adjusting the safety switch position
The safety switch (1) is normally installed as shown in figure
[A].
However, if the processing method used for the table leaves
too much space between the machine head and the table
hole, it may adversely affect the operation of the safety
switch (1).
<Adjustment method>
The standard amount of clearance between the machine
head and the table hole is 1.25 mm. (At this time, the
clearance between the safety switch (1) and the table hole is
4.5 mm.)
If the clearance is too great, place a washer (2) on the
machine head side as shown in figure [B] and re-install the
safety switch (1).
*
If the position cannot be satisfactorily adjusted in this way,
add more washers of the same thickness.
