Belt Table Miter Slot Parallelism
Adjustment
1. Disconnect the power to the machine to prevent acci-
dental start-ups.
2. Set the table angle to zero.
3. Place a scale or adjustable machinist's square against
either the left or right edge of the belt or platen and mea-
sure the distance to the miter slot edge (See Figure 19).
4. Move the measuring device to the opposite edge of the
belt or platen and measure the distance to the miter slot.
5. Adjust the table by loosening the three attachment screws
under the table, then move the table until the distance be-
tween the miter slot and belt or platen is equal on both
sides.
6. Tighten the three attachment screws.
7. Reconnect the electrical power to the machine.
Belt Table Angle Adjustment
1. Loosen the table locking handle and tilt the table
upward to about 15
o .
2. Flip out the stop bracket (See Figure 21).
3. Lower the table until its adjusting screw touches
the stop bracket.
4. Place a machinist's square against the table and
belt or platen.
5. If adjustment is required, turn the adjusting screw
(Figure 20) until the table is exactly square to the platen.
6. Check the pointer. If it is not on 0
o , loosen the
pointer screw and adjust the pointer until it is on 0 o .
7. Tighten the pointer screw.
8. Loosen the table lock handle and tilt the table until
its stop contacts the 45
o stop position.
9. Using a machinist's protractor set on 135 o (90 o +
45 o ) adjust the screw until the table and platen are in
correct adjustment. DO NOT reset the pointer after
this operation.
