ADJUSTING SLIDING FIT BETWEEN

 

 

 

 

TRUNNION AND BEVEL BRACKET

D

After a long period of time it may become necessary to

 

 

 

 

adjust the sliding fit between the trunnion (A) Fig. 27,

 

 

 

B

and the bevel bracket (B) by tightening adjusting nut

 

 

 

 

 

 

 

(C). NOTE: This adjustment must be made with the

 

 

 

 

bevel lock handle (D) loose. Correct adjustment is when

 

 

 

 

a good snug sliding fit is obtained between these two

 

 

 

 

parts. This adjustment should not be too tight that it

 

C

restricts the sliding movement or too loose that it affects

 

 

 

 

 

the accuracy of the saw cut.

lock handle.

 

 

3.Using a square (A) Fig. 28, place one end of the square on the table and the other end against the blade, as shown. Check to see if the blade is at 90 degrees to thetable.

4.If an adjustment is necessary, loosen bevel lock handle. Then loosen locknut (B) Fig. 29, and turn

adjusting screw (C) until head of screw (C) contacts
