Disc table adjustments
10.4.1
Adjusting disc table angle
To avoid trapping the work or
fingers between table and sanding disc, the
table edge should be positioned a maximum of
1/16-inch from sanding disc.
Disconnect machine from power source.
The disc table is positioned at 90 degrees to the
sanding disc for most operations (see Figure 14).
To check and see if table is 90 degrees, place a
square on the table with one end of square against
sanding disc. If an adjustment is necessary, loosen
the cap screws and move table until it is 90
degrees to sanding disc. Tighten screws to secure
table.
The disc table (see Figure 15) can be tilted
downward 45 degrees. Loosen the two cap screws,
tilt table to desired angle, and tighten cap screws.

10.4.2
Adjusting disc-to-table gap
Disconnect machine from power source.
Adjust sanding disc to leave a maximum of 1/16-
inch gap between table and disc. This can be
accomplished by moving sanding disc in or out on
motor shaft (see Figure 16).
Use T-handle type hex wrench. Put the wrench
through the hole in top of disc guard. Loosen
setscrew in hub of disc. Move disc in or out as
needed to establish a 1/16-inch gap. When gap is
established, tighten setscrew.

Changing abrasive belts
1. Disconnect machine from power source.
2. Remove upper belt cover by removing screw
and nut (see Figure 17). Remove two knobs
from side cover. Remove side cover.
3. Press down on tracking knob to release belt
tension (see Figure 18).
4. Remove belt from the three pulleys. Install
replacement belt.
5. Replace side cover; secure cover with two

IMPORTANT:
Some belts have a directional
arrow printed on inside of belt. In these cases
the belt must be installed so directional arrow
is in same direction that machine is running.
The sanding belt travels down the front of
machine.
6. Before installing upper belt cover, start sander
and check belt tracking. Adjust tracking if
needed (refer to
sect. 10.1
).
