Naturally, in all sanding operations, best results will be obtained if you select the proper size and type of abrasives. Only garnet, aluminum oxide and silicon carbide are recommended for use with finishing sanders.

Before starting to work, make sure you have the right abrasive for the material on which the sander is to be used. Make sure you use the correct size abrasive paper or cloth. Cut, do not tear, the abrasive sheets to size.

ATTACHING STIKIT™ ABRASIVE

STIKIT™ Abrasives are available in pre-cut sheets, or in rolls. A convenient dispenser is also available for the rolls.

To install STIKIT™ abrasive, cut a 41/4" long piece of abrasive from a roll (or use a pre-cut sheet), align abrasive with sander pad and press in place as shown in Fig. 1.

Punch holes in paper (for dust extraction), as instructed in PAPER PUNCH section of this manual.

NOTE: DO NOT store Sander with an abrasive disc installed. Heat generated by the sanding operation increases the adhesive bond between the disc and pad. If disc is left on pad for an extended time after use, it can become difficult to remove. If sanding disc is difficult to remove, use the sander on a piece of scrap wood for one to two minutes to warm the paper. This should make removal easier.
