3. Refer to Adjusting Grinder Tilt on Page 22
to adjust grinder to vertical position.
4. Pull belt-tension release lever backward (see
Figure 24) to release belt tension. The lever
will snap into position.
7. Rotate belt by hand to verify belt moves freely
without rubbing against any parts of machine.
8. Check and adjust belt tracking (see Adjusting
Belt Tracking on Page 21).
5. Remove old sanding belt from wheels.
6. Place new sanding belt on wheels, then pull
belt tension lever forward to tension belt.
Note: The included belt uses a butt joint, so it
does not have an intended rotation direction.
If you choose to replace it with one that uses
a lap joint, you must match rotational arrows
of belt with belt rotation direction of grinder
(see
Figure 24).

Replacing
Abrasive Belt
The grinding belt on the G0898 should be changed
whenever there is a noticeable change in grind-
ing quality/performance. You may also need to
change grit sizes of grinding belt for quick material
removal or finer finishes.
This machine uses a 2" x 48" belt. Below is a
chart that groups abrasives into different classes,
and shows which grits fall into each class.
To achieve a fine finish, the general rule is to grind
a workpiece with progressively higher grit num-
bers, 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 metal you use and your
stage of finish will determine the best grit types to
install on your grinder.
Grit Class
36 Extra Coarse
60 Coarse
80–100 Medium
120–180 Fine
