ADJUSTING MITER GAGE SLOT ALIGNMENT

Make certain machine is

disconnected from power source

before making adjustments.

• Check to see if the miter gage slot (A), shown in

Figure 11, is parallel with the disc by placing a

combination square in the miter gage slot with one

end of the square against the disc as shown.

• Using a pencil, make a mark on the abrasive disc

where the square contacts the disc.

• Rotate the disc 180° and check the distance

between the disc and miter gauge slot at the

opposite end of the table. If an adjustment is

necessary, proceed as follows:

NOTE: When making the following adjustment, ensure

the table locking wing nut is tightened.

• Using the supplied hex wrench, loosen the four

screws (B) indicated in Figure 12, which secure the

table to the trunnions.

• Adjust the table by moving it in or out until the miter

gage slot is equidistant from the disc at both ends of

the table.
