ABRASIVE BELT SANDING
1. Finishing flat surfaces: Hold workplace firmly with both
hands; keep fingers away from abrasive belt. Use table to
position and secure work being sanded. Keep end butted
against table and move work evenly across abrasive belt.
2. Finishing long pieces: Use belt in horizontal position with
work stop. Apply only enough pressure to allow abrasive
belt to remove material.
Use work stop to position and secure work being sanded.
Keep end butted against work stop and move work
evenly across abrasive belt. Use extra caution when
finishing very thin pieces.
3. Finishing curved edges: Finish outside curves on flat
portion or abrasive belt. Finish inside curves on idler
drum portion of abrasive belt.
4. Finishing end grain: It is more convenient to finish ends
of long workpieces with the abrasive belt in a vertical
position.
Position table on belt side of sander. Move work evenly
across abrasive belt. For accuracy, use miter gauge.
Table may be tilted for beveled work.
ABRASIVE DISC SANDING
1. Abrasive disc sanding is well suited for finishing small flat
surfaces and convex edges.
2. Move workpiece across down side (left) of abrasive disc.
Hold workpiece firmly with both hands; keep fingers away
from abrasive disc.
3. Abrasive disc moves faster and removes more material at
outer edge.
4. For accuracy, use miter gauge.
USING MITER GAUGE (Fig. J)
1. Use miter gauge (1) for securing the work and holding
the proper angle while standing.
2. Use a combination square (4) to adjust miter gauge
square to belt (disc). Pointer (2) should be at zero.
Loosen screw and reposition pointer if necessary.
3. After setting miter gauge square to belt (disc), adjust to
desired angle by repositioning the miter gauge scale
and locking it into place with knob (3).
