CHANGING THE SAW BLADE
Use only 10" diameter blades with 5/8" arbor holes, rated at 3600 rpm or higher.
NOTE: Two 7/8" wrenches are supplied with the saw for changing the saw blade - a closed-end wrench (A) Fig. 61 and an
open-end wrench (B).
1. Remove the table insert (C) Fig. 60, and raise the saw blade to its maximum height.
2. Place the open-end wrench (B) Fig. 61 on the flats of the saw arbor. Use the closed-end wrench (A) to turn the arbor nut
(D) toward the front of the saw to loosen. Remove the arbor nut, blade flange (C), and saw blade.
3. Place the new blade on the arbor with the teeth pointing down as the blade rotates toward the front of the saw table.
Install the outside blade flange and arbor nut to secure the blade. With the wrench (B) Fig. 61 on the flats of the arbor,
tighten the arbor nut by turning wrench (A) toward the rear of the saw.
4. Replace the table insert.
NOTE: Use a sharp blade that is proper for your project. Do not stack blades when you store them. Place a barrier (cardboard,
cloth, etc.) between the blades to keep them from touching.

3. To adjust, loosen the two hex head bolts (B) Fig. 59 that
hold the rear trunnion to the saw table.
4. Use a rubber mallet (or a regular hammer and a block of
wood) to tap the trunnion (C) until the saw blade is in the
center of the table insert slot, and parallel to the miter
gauge slot.
5. Tighten the two hex head bolts that were loosened in
STEP 3.
6. Tilt the blade to 45°. Turn the saw blade by hand to
ensure that it does not contact the table insert.
BACKLASH ADJUSTMENTS FOR BLADE RAISING AND BLADE TILTING MECHANISMS
If any play is detected in the blade-raising or blade-tilting mechanisms, make the following adjustments:
NOTE: In the illustration (Fig. 62), the machine was turned
upside down and the blade removed for clarity and safety.
1. Adjusting the blade-raising mechanism - Loosen the
locknut (A) Fig. 62 and turn the eccentric sleeve (B) until
all play is removed. Tighten the locknut.
2. Adjusting the blade-tilting mechanism - Loosen the
locknut (C) Fig. 62 and turn the eccentric (D) until all
play is removed. Tighten the locknut.
