１０-２. 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 1.5 mm.
If the clearance is 3.5 mm or more, install the safety switch
(1) so that the washer (2) is on the machine head side as
shown in Figure [B].
* If the position cannot be satisfactorily adjusted in this way,
add more washers of the same thickness.
