—If the workpiece is rough to the touch,
repeat with additional passes until it is
smooth.
—If repeated passes through the machine
do not yield the desired result, the cutter-
headmay be too low and the sanding belt
may not be contacting the workpiece. Try
raising the cutterhead incrementally 0.1mm
between passes and continue feeding the
workpiece through until it is smooth.
