REMOVING / REPLACING THE ZERO CLEAR- ANCE THROAT PLATE

See Figure 15.

When squaring the saw blade, it may be necessary to move the throat plate away from the blade. Once the saw’s alignment has been confirmed, return the throat plate to its original position. Never operate the saw without a throat plate installed.

Unplug the saw.

Using the blade wrench provided, loosen the screws securing the right side of the zero clearance throat plate.

Slide the throat plate away from the blade as far as possible.

Retighten the screws, being careful not to overtighten which can cause the throat plate to bow or bend.

Repeat the above steps for the left side of the throat plate.

CENTERING THE SAW BLADE BETWEEN THE SLIDE BARS

See Figure 16.

The saw blade should be centered (approximately) between the two pieces of the zero clearance throat plate and there should be no play between the right slide bar and the pivot assembly. Standing in front of the saw, make a visual inspection. If adjustment is required:

Unplug the saw.

With the miter at 0˚ and the bevel at 0˚, lock the saw into the transport position.

Loosen the jam nuts on the two top and two bottom gib screws as shown.

Loosen the two top gib screws.

Tighten or loosen the lower gib screws as required to center the blade between the two pieces of the throat plate.

Once centered, tighten the lower two jam nuts.

�����NOTE:To minimize play in the slide bars, gradually tighten the two top gib screws while sliding the saw back and forth over the slide bars. Tighten the top jam nuts.
