Horizontal Sanding (G1140); Sanding Tips; Choosing Sandpaper - Grizzly G1531 Owner's Manual

Horizontal Sanding
(G1140)
To perform horizontal sanding:
1.
Make sure belt tracking is correctly set (see
Tracking Belt on Page 28).
2. Tilt the platen so it is horizontal (see Page 25,
Platen Tilt), then lock it in place.
3. Turn the sander ON.
4.
While supporting the workpiece against the
back stop and keeping your fingers away
from the belt, slowly feed the workpiece into
the belt, as shown in Figure 40.
Note: Apply even hand pressure while mov-
ing the workpiece back and forth for even belt
wear.

Sanding surfaces can cause serious person-
al injury if they come in contact with fingers,
hands or other body parts. Use extreme care
to provide a safe distance between the belt
and any part of your body.

Sanding Tips

•
Replace the sandpaper with a higher grit to
achieve a finer finish.
• Extend the life of the sandpaper by regu-
larly using a PRO-STICK® sanding pad (see
Accessories on Page 29).
• When sanding workpieces with a bow or
crown, place the high point up on the table
(prevents the workpiece from rocking) and
take very light passes.

Choosing Sandpaper

The Model G1140/G1531 uses a 6" x 80" sanding
belt.
There are many types of sanding belts to choose
from. We recommend aluminum oxide for gen-
eral workshop environments. Below is a chart
that groups abrasives into different classes, and
shows which grits fall into each class.
Grit Class
36 Extra Coarse
60 Coarse
80–100 Medium
120–180 Fine
The general rule of thumb is to sand a workpiece
with progressively higher grit numbers, with no
one grit increase of more than 50. Avoid skipping
grits; the larger the grit increase, the harder it will
be to remove the scratches from the previous
grit.
Ultimately, the type of wood you use and your
stage of finish will determine the best grit types to
install on your sander.
