ABRASIVE BELT SANDING
• Finishing flat surfaces: Hold workpiece 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.
• Finishinglongpieces:Usebeltinhorizontalpositionwith
workstop.Applyonlyenough 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.
• Finishing curved edges: Finish outside curves on fiat por-
tion of abrasive belt. Finish inside curves on idler drum por-
tion of abrasive belt.
• 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
• Abrasive disc sanding is well suited for finishing small fiat
surfaces and convex edges.
* Move workpiece across down side (left) of abrasive disc.
Hold workpiece firmly with both hands; keep fingers away
from abrasive disc.
• Abrasive disc moves fastest and removes more material at
outer edge.
• For accuracy, use miter gauge.
USING MITER GAUGE
Refer to Figures 14, 15 and 16.
• Use the miter gauge for securing the work and holding the
proper angle while sanding.
• Before using gauge, check that the table slot is parallel to
belt (disc).
• Use a combination square to check distance from slot to
belt (disc) on each side of table.
• If table needs adjustment, loosen the three bolts beneath
table, move table and secure in position.
Figure 15 -Table Adjustment
• Use a combination square to adjust miter gauge square to
belt (disc). Pointer should be at zero. Loosen screw and
reposition Pointer if necessary.

Be certain motor is kept clean and is frequently vacuumed
free of dust.
Use soap and water to clean painted parts, rubber parts and
plastic guards.
LUBRICATION
The shielded ball bearings in this tool are permanently
lubricated at the factory. They require no further lubrication.
• When operation seems stiff, a light coat of paste wax
applied to the belt table and disc table win make it easier to
feed the work while finishing.
• Do not apply wax to the belt platen. Belt could pick up wax
and deposit it on wheels causing belt to slip.
KEEP TOOL IN REPAIR
• If power cord is worn, cut, or damaged in any way, have it
replaced immediately.
• Replace worn abrasives when needed.
• Replace any damaged or missing parts. Use parts list to
order parts.
