EDGE SANDING
When edge sanding, it is advisable to raise one end of
the table as shown in Fig. 36. This allows cooler belt
running, prevents spot wear, reduces material burning
and promotes longer belt life. The table should be
positioned so it is close to, but not contacting the
sanding belt.
CONTOUR SANDING AROUND THE
DRIVE PULLEY
IMPORTANT: The hinged dust chute (A) Fig. 37, must be
flipped up to allow contour sanding around the drive
pulley (C). The auxiliary end table (B) should be used to
support the workpiece. The table (B) should be
positioned close to, but not touching the sanding belt
(C). It is advisable to raise or lower the table (B)
periodically to prevent spot wear and improve belt life.
CONTOUR SANDING AROUND THE
AUXILIARY ABRASIVE DRUM
SPINDLE
IMPORTANT: The hinged dust chute (A) Fig. 38, must be
flipped up to allow contour sanding around the auxiliary
abrasive drum (B). Whenever possible the auxiliary end
table (C) should be used to support the workpiece when
contour sanding. The auxiliary end table (C) should be
positioned close to but not touching the abrasive drum
(B). It is advisable to raise or lower the table (C)
periodically prevent spot wear and improve drum life.
