2. Turn the knob clockwise to decrease the
oscillation speed and counterclockwise to
increase it.
Note: To re-establish the factory setting,
back out the knob until it stops, then turn it

turns.
3. Tighten the lock nut loosened in Step 1 to
secure the knob.
As you experiement with different oscillation
speeds, make a note of the timing from one
side to the other when you find the best sand-
ing results. That way you can readjust the
oscillation speed later if sanding that type of
material again.
To adjust the oscillation speed:
1. Loosen the lock nut on the speed control
adjustment knob (
Figure 30).
Choosing Sandpaper
When selecting sandpaper, keep in mind that the
Model G0677 accepts only
25"
wide by 60" long
belts. The grit you choose will depend on the
type of work, the species of wood and the stage
of finishing.
When choosing which sandpaper to
use, use these grit numbers as a general guide to
sandpaper type:
Grit
Type
60 or less ..................................................Coarse
80-100 ................................................... Medium
120-150 ......................................................... Fine
We recommend using aluminum oxide sanding
belts for best results. The general rule of thumb
is to sand a workpiece with progressively higher
grit numbers, with no one grit increase of more
than 50; however, the type of wood and desired
finish will determine the best grit to use.
Note:
Sandpaper finer than 150 grit can often load up or
burn workpieces.
Oscillation Speed
The oscillation speed of the sanding belt is adjust-
able. Different oscillating speeds yield different
sanding results. We recommend trying various
speeds on a scrap piece of wood similar to the
workpiece being used. The oscillation speed is
measured by how long it takes the belt to move
from one side to the other.

Sanding Belt
Replacement
To replace the sanding belt:
1. Follow Steps 1–3 on Page 19.
2. Remove the sanding belt.
3. Making sure the rotation arrows on the sand-
ing belt point the same direction as those
shown in
Figure 18 on Page 19, install the
new sanding belt by starting first on the upper
roller, and then the lower roller.
Note:
The sanding belt must be centered
between the limit switches and the edge of
the sanding belt must be between tongs of
the oscillation controller as shown in
Figure
18 on Page 19. Damage to the sanding belt
could occur if the sander is turned
ON before
the sanding belt is correctly positioned.
