9-2. 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 bed 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 bed
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 bed side as
shown in Figure [B].
* If the position cannot be satisfactorily adjusted in this way,
add more washers of the same thickness.
