-12- G8793 12" Double Disc Sander
SECTION 5: ADJUSTMENTS
Tables
The tables should be adjusted so they are per-
pendicular to the face of the sanding disc when
the table tilt is set to 0˚. Using a try square or
machinist’s square, set one edge of the table sur-
face and the other against the face of the disc.
(This can be done with the sandpaper installed,
although it is somewhat easier to measure if the
disc does not have the sandpaper disc installed)
See Figure 6. Loosen the star knob and adjust
the table angle until it is perfectly perpendicular.
Tighten the star knob.
Loosen the bolt holding the degree pointer and
move it so it is pointing to 0˚. Tighten the bolt.
Move the table tilt and return it to the 0˚ point
using the indicator, then recheck with the square
to verify the setting.

Miter Gage
The miter gauge needs to be adjusted so that it is
perfectly perpendicular to the face of the wheel
when it is mounted in the table slot. There is no
adjustment in the table itself. The miter gauge
face relative to the the table slot is adjustable.
Use a try square or machinist’s square with one
edge against the face of the miter gauge and the
other against the disc face. See Figure 7.
Loosen the adjusting screw on the miter gauge
and adjust so that it is flush with the edge of the
square. Tighten the gauge adjusting screw, and
double check. Sometimes the tightening proce-
dure can affect the adjustment.
Set the pointer on the miter gauge to 0˚ by loos-
ening the screw holding the pointer in position.
Adjust the pointer and retighten.
