clockwise, depress the lock lever (B), and rotate the table.

ADJUSTING THE SLIDING FIT BETWEEN THE MOVABLE TABLE AND THE BASE
DISCONNECT THE MACHINE FROM THE POWER SOURCE.
To adjust the sliding fit between the movable table and the base, turn the nut (A) Fig. 14 (located under the saw) clockwise to
increase the sliding fit (opposite to decrease the fit). This adjustment should not be so tight that it restricts the rotating
movement of the table, or so loose that it affects the accuracy of the saw.
ADJUSTING THE FENCE 90° TO THE BLADE
IMPORTANT: Before making this adjustment, set the blade at 0° to the table. See section "ADJUSTING 0° AND 45° BEVEL
POSITIVE STOPS."
DISCONNECT THE MACHINE FROM THE POWER SOURCE.
1. Rotate the movable table so that the blade is 90° to the fence and the positive stop is set for 0°.
2. Place one end of a square (A) Fig. 15 against the front of the fence (B), and the other end against the blade, with the blade
locked in the down position. The fence should be 90° to the blade.
3. To adjust the fence (B) Fig. 15, use the supplied wrench to loosen the two screws (C) that attach the fence to the base.
Adjust the fence (B), and tighten the screws (C).
4. Adjust the pointer by loosening the screw (A) Fig. 16, aligning the pointer (B) with the 0° mark on the scale, and tighten
the screw (A).
