Model G0866 (Mfd. Since 11/18)
Adjusting Platen
This sander is equipped with an adjustable platen
(see
Figure 54) with a graphite pad that is
designed to be used during finish sanding to
create a polished-type finish and to prepare the
workpiece for orbital sanding or a finish coat.

The platen position allows for 3 basic types of
sanding: up, even, and down, which are adjusted
by rotating the platen height dial (see
Figure 55
)
to the desired position. The platen height gauge
indicates the current position of the platen.

Unlike the sanding belts, which typically produce
short but deep scratch patterns, the platen pro-
duces long and shallow scratch patterns that
create a smoother finish. Due to the cushioned-
construction, the platen is less likely to leave belt-
splice or chatter marks.
7. Install sanding belt on upper roller and lower
roller, starting with upper, making sure rota-
tion arrows on sanding belt point in same
direction as those shown in
Figure 53.
Note: Sanding belt must be centered between
limit switch tips, and edge of sanding belt
must be between tongs of belt oscillation con-
troller fork, as shown in
Figure 53. Damage
to sanding belt and sander may occur if
sander is tensioned and turned
ON before
sanding belt is correctly positioned.
