ELECTRICAL CONNECTIONS

WARNING: All electrical connections should
!
be done by a qualified electrician. Failure
to comply may result in serious injury. The
machine must be properly grounded.
Consult the electrical schematics on pages 34-36 for
proper wiring of the table saw.

ADJUSTMENTS

CAUTION: Disconnect machine from
!
power source before making adjustments.
BLADE RAISING & TILTING
1. The front handwheel (A) controls the raising and
lowering of the blade. The side handwheel (B) con-
trols blade tilt, which is indicated by the scale (C).
The lock knobs (D) are used to lock the setting of the
handwheels. See Figure 11.

MITRE SLOT ALIGNMENT

1. To check the alignment of the mitre slot to the
blade, raise the blade to its maximum height at the
zero degree (vertical) position.
2. Mark one tooth with a grease pencil and position
the tooth slightly above the top edge of the table at the
front.
3. Raise the mitre gauge slightly out of its slot to
serve as a shoulder. Using a combination square
against the side of the bar, slide the scale over until it
touches the tip of the blade and lock the scale in posi-
tion. See Figure 11.
4. Rotate the marked tooth so that it is slightly above
the table top at the rear and, using the square as be-
fore, check whether the distance to the blade is the
same. See Figure 12. If it is not, loosen the three
mounting screws that lock the table to the cabinet
(two in front, one in back) as shown in Figure 13, and
nudge the table to bring the mitre slot in line with the
blade.
5. The blade must be kept centered with the slot in
the table insert to ensure clearance at both the 90
degree and 45 degree positions. After alignment, lock
the table to the cabinet by re-tightening the three
mounting screws.
