4. Raise miter gauge slightly out of its slot to
serve as a shoulder. Using a sliding square (B)
against the side of the bar, slide the scale over
until it touches the tip of the blade, and lock
scale in position.

Figure 8-11
5. Rotate marked tooth (A) so that it is slightly
above table top at the rear, using the square
as before to verify that distance to blade is
identical. See Figure 8-11. If the two distances
are not the same, make a careful note of the
difference.
6. Loosen table screws (item #23, sect. 14.1.1),
and nudge table according to the distance you
noted.
7. Retighten screws firmly.
8. Verify alignment, angle pointer setting, fence
setting, etc. Make any needed adjustments.

8.8 Belt adjustment

8.8.1 Belt tension

See Figure 8-12.
Drive belt tension should be inspected after the first
few days of operation, as a belt may stretch slightly
during initial use; also inspect it periodically
thereafter.
To tighten belt:
1. Disconnect machine from power source.
2. Loosen screw (C, Figure 8-12) with 17mm
wrench.
3. Slightly loosen
adjustable) wrench.
4. Push motor to the right and tighten screw (C)
to tension belt. Retighten nut (D). Verify proper
tension by pushing on belt midway between
pulleys; deflection should be about 1/2-inch.
If belt shows signs of wear, fraying, cracks, etc. it
should be replaced, as follows.

8.8.2 Belt replacement

See Figure 8-12.
1. Lower trunnion completely.
2. Loosen screw (C) with 17mm wrench.
3. Slightly loosen
adjustable) wrench.
4. Pivot motor to the left to release tension.
5. Replace belt.
6. Push motor to the right and tighten screw (C)
to tension new belt. Retighten nut (D). Verify
proper tension by pushing on belt midway
between pulleys; deflection should be about
1/2-inch.

8.9 Zero-clearance insert setup

Under normal operations where the standard table
insert (provided) is used, the top edge of saw blade
will come to rest approximately 1/8" below table
surface when blade is at lowest position.
In situations where a zero-clearance insert is
desired, the saw blade may be lowered further for
accommodation of inserts that have potential
clearance issues with the blade. This is done as
follows:
1. Remove blade guard and pawls (Figure 6-10).
2. Open side cover and locate blade depth stop
screw (A, Figure 8-13) located between arbor
pulley and motor.
