6-2. Sanding Pressure
Sanding pressure for FS-100C is 20 to 50 N and
for FS-50A is 10 to 30 N. Applying excessive force
will lower sanding efficiency. For flat work, adjust
pressure so force is applied evenly to the entire
surface of the Rubber Pad. Uneven pressure will
result in an irregular surface.
