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.

the required spring stroke can be maintained.

Clearance 
is too large. 

If the spring stroke is too small, the safety
switch will not operate. 

Reduce the clearance.
