Workpiece
Inspection
Some workpieces are not safe to sand, or they
may require further preparation before they can
be safely sanded without increasing risk of injury
to the operator or damaging the sanding belt or
the sander.
Before sanding, inspect all workpieces for the
following:
•
Material Type: This machine is intended for
sanding natural and man-made wood prod-
ucts, and laminate covered wood products.
This machine is NOT designed to sand metal,
glass, stone, tile, plastics, drywall, cemen-
tious backer board, etc.
Sanding improper materials increases the
risk of respiratory harm to the operator and
bystanders due to the especially fine dust
inherently created by all types of sanding
operations—even if a dust collector is used.
Additionally, the life of the machine and sand-
ing belts will be greatly reduced (or immedi-
ately damaged) from sanding improper mate-
rials or from exposure to the fine dust created
when doing so.
•
Foreign Objects: Nails, staples, dirt, rocks
and other foreign objects are often embed-
ded in wood. While sanding, these objects
can become dislodged and tear the sanding
belt. Always visually inspect your workpiece
for these items. If they can't be removed, DO
NOT sand the workpiece.
•
Wet or "Green" Stock: Sanding wood with a
moisture content over 20% causes unneces-
sary clogging and wear on the sanding belt,
increases the risk of kickback, and yields
poor results.
•
Excessive Warping: Workpieces with exces-
sive cupping, bowing, or twisting are dan-
gerous to sand because they are unstable
and often unpredictable when being sand-
ed. DO NOT use workpieces with these
characteristics!
•
Minor Warping: Workpieces with slight cup-
ping can be safely supported if the cupped
side is facing the table. On the contrary, a
workpiece supported on the bowed side will
likely rock during sanding, which may result
in the workpiece being ejected back toward
the operator (i.e. kickback) with enough force
to cause an impact injury.
Required Sanding Belt Size ..............16" x 48"
Included 16" x 48" Sanding Belts
Qty
100-Grit ............................................................. 1
180-Grit ............................................................. 1
The Model G0819 only accepts 16"
wide by
48" long sanding belts. For additional sanding
belt selections beyond those included with the
machine, see the
Accessories section, beginning
on
Page 33.
We recommend using aluminum-oxide sand-
ing belts for best results. The grit you choose
will depend on the condition and species of wood,
and the level of finish you wish to achieve.
When choosing a sanding belt, use these grit
numbers as a general guide:
Grit
Type
60 or less ..................................................Coarse
80-100 ................................................... Medium
120-150 ......................................................... Fine
180+ ............................................................Finish
The general rule of thumb is to sand a workpiece
with progressively higher grit numbers—in incre-
ments of 50 or less.
Note: Sandpaper finer than 180-grit will easily
load up or burn workpieces.
