ADJUSTING THE 90 ° AND 45 ° POSITIVE STOPS

(FIG. R, S)

Your saw has positive stops that will quickly position the saw blade at 90° or 45° to the table. These stops were set at the factory. Make adjustments only if necessary.

900 Stop

1.Disconnect the saw from the power source.

2.Turn the blade elevation handwheel and raise the blade to the maximum elevation.

3.Loosen the blade bevel lock knob and move the

blade to the maximum vertical position. Tighten the lock knob.

4.Place a combination square on the table and against the blade (1')to determine if the blade is 90° to the table. (FIG. R)

5.If the blade is not 90° to the table, loosen the two

set screws (4), located in the bottom of the table saw, (FIG. S) with the 3mm hex key, and back off the collar (5).

6.Loosen the bevel lock knob. Turn the blade tilting handwheel to move the blade until it is 90° to the table.

7.Adjust the collar (5) so it contacts the bracket (3) when the blade is 90° to the table. Tighten the two set screws (4).
