ADJUSTING 0 AND 45 DEGREE POSITIVE STOPS

Your saw is equipped with positive stops for rapid and accurate positioning of the saw blade at 0 and 45 degrees to the table. This saw has the capability to go 2 degrees beyond 0 and 45 degrees (-2º to 47º). To adjust the positive stops, proceed as follows:

1. DISCONNECT MACHINE FROM

POWER SOURCE.

2.Remove the blade guard and spreader assembly.

NOTE: SEE THE SECTION “REMOVING BLADE GUARD/SPREADER ASSEMBLY.”

3.Raise the saw blade to its maximum height.

TO ADJUST POSITIVE STOP AT 0 DEGREES

4.Loosen the blade tilting lock handle, move the blade tilting mechanism as far as possible to the left and tighten the blade tilting lock handle.

5.Place a square (A) Fig. 20, on the table with one end of the square against the blade, as shown, and check to see if the blade is at 90 degrees to the table. If it is not, loosen screw (B) a few turns and move the blade tilting mechanism until the blade measures 90 degrees to the table. Then tighten blade tilting lock handle and tighten screw (B) until it bottoms. NOTE: CHECK TO SEE IF THE

TILT INDICATOR POINTER POINTS TO THE ZERO MARK ON THE SCALE. ADJUST IF NECESSARY.

TO ADJUST POSITIVE STOP AT 45 DEGREES

6.Loosen the blade tilting lock handle, move the blade tilting mechanism as far as possible to the right and tighten the blade tilting lock handle.

7.Place a square (A) Fig. 21, on the table with one end of the square against the blade as shown, and check to see if the blade is at 45 degrees to the table. If it is not, loosen screw (C) a few turns and move the blade tilting mechanism until the blade is at 45 degrees to the table. Then tighten blade tilting lock handle and tighten screw

(C) until it bottoms.

RIP FENCE OPERATION AND ADJUSTMENTS

1.To move the rip fence (A) Fig. 22A, along the table, lift up fence locking lever (B), slide the fence to the desired location on the table and push down fence locking lever (B) to lock the fence in position.

2.A pointer is supplied to indicate the distance the fence is positioned away from the saw blade. If an adjustment to the pointer (D) is required, loosen the screws (C) Fig. 22B, that fasten the pointer window to the fence head and adjust the pointer accordingly.

NOTE: THE RIP SCALE HAS TWO SETS OF MEASUREMENTS DISPLAYED ON IT. THE TOP SCALE IS USED WHEN THE RIP FENCE GUIDE RAIL IS COLLAPSED. THE BOTTOM SCALE IS USED WHEN THE RIP FENCE GUIDE RAIL IS FULLY EXTENDED.
