When surfacing (see Fig. 54), or edge sanding (see Fig.

55), the sanding arm is in the horizontal position and the

table (A) Fig. 54 and Fig. 55, must always be used to

prevent the workpiece from being carried along the belt.

Always hold the workpiece firmly, keeping your fingers

away from the sanding belt. Always keep the end of the

workpiece against the table and move the workpiece

evenly across the sanding belt. Apply only enough

pressure to allow the sanding belt to remove material.

Use extra caution when sanding very thin pieces.

THE EDGE OF THE TABLE MUST BE

POSITIONED A MAXIMUM OF 1/16

INCH AWAY FROM THE SANDING BELT

TO AVOID TRAPPING THE WORK OR

FINGERS BETWEEN THE TABLE AND

SANDING BELT.

ONLY TEAR THE BELT A FEW INCHES AT A TIME ONE WAY THEN REVERSE THE TEARING

ACTION. THIS METHOD WILL REDUCE THE TENDENCY OF THE BELT TO UNRAVEL.

For certain applications, a mist coolant attachment (not supplied by Delta) will be helpful. If the use of a mist coolant

causes the Abrasive Belt to slip on the lower drive pulley, this can be corrected by using a "tire" which can be

homemade by wrapping the pulley with a piece of coated abrasive belt. The grit is, of course, turned to the outside

and cement should be used sparingly to avoid lumps under the "tire."
