Installing/Changing Blades

Disconnect machine from

power source. Blade teeth are sharp, use care
when handling the blade. Failure to comply may
cause serious injury.

1. Disconnect machine from power source.

2. Decrease blade tension by rotating the blade

tension handwheel (A, Fig. 17) according to the
arrow direction in until the handwheel stops.

3. Remove

the

table insert (B, Fig. 17).

4. Remove the tapered pin (C, Fig. 17) by using

the wrench attached with the pin together.

5. Lower the upper blade guide assembly

(H, fig. 18) by loosening the knob (F, Fig. 18)
and rotating the handwheel (G, Fig. 18).

6. Open

upper and lower front doors (D, Fig. 17).

7. Carefully remove the blade from between

upper and lower blade guides; then remove the
blade from the upper and lower wheels.

8. Guide new blade through table slot (E, Fig. 17).

Place blade in upper and lower blade guides.

Note: Make sure blade teeth point down
toward table (see inset, Fig. 17), and toward
the front of the saw.

Hint: If the teeth cannot be made to point
down, try turning the blade inside out first, then
reattempt.

9. Position blade on the middle of the upper and

lower wheels.

10. Replace the table insert (B, Fig. 17) and

tapered pin (C, Fig. 17).
