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 nut (D) with 1-1/4" (or
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 nut (D) with 1-1/4" (or
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.
3. Using a 14mm open wrench, loosen hex nut
(B, Figure 8-13). This will allow hex cap screw
to be turned and saw blade to be adjusted
lower.
4. Use height adjust handwheel (B, Figure 8-1),
to lower saw blade all the way.
The zero-clearance insert can now be placed in
table opening without contacting blade.
insert with saw blade in tilted position. Never
operate saw without blade guard, riving knife,
and anti-kickback pawls for operations where
they can be used.
When the standard insert is to be used again, the
saw blade must be readjusted as follows:
5. With the height adjust handwheel (B, Figure 8-
1), adjust blade height until top of saw blade is
1/8" below top of table.
6. The blade depth stop screw (A, Figure 8-13)
should be resting against the trunnion. Verify
this; then tighten hex nut (B, Figure 8-13).
7. Reinstall standard insert, pawls and blade
guard.
