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
Limit Switch
by rotating the platen height dial (see
Tip
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.
