Choosing Sandpaper

There are many types of sanding belts to choose from. We recommend aluminum oxide for gen- eral workshop environments. Below is a chart that groups abrasives into different classes, and shows which grits fall into each class.

Grit	Class	Usage
36	Extra Coarse	Rough sawn boards,
		thickness	sanding,
		and glue removal.
60	Coarse	Thickness	sanding
		and glue removal.
80–100	Medium	Removing	planer
		marks and initial finish
		sanding.
120–180	Fine	Finish sanding.

The general rule of thumb is to sand a workpiece with progressively higher grit numbers, with no one grit increase of more than 50. Avoid skipping grits; the larger the grit increase, the harder it will be to remove the scratches from the previous grit.

Ultimately, the type of wood you use and your stage of finish will determine the best grit types to install on your sander.

Paper Replacement

The Model G0459/G0459P is designed for 3" wide hook-and-loop sandpaper rolls.

To change sandpaper:

1.DISCONNECT POWER TO THE SANDER!

2.Open the top cover to expose the drum.

3.Unwind the old sandpaper and notice the direction that it was wrapped around the drum.

5.Wrap the sanding drum with the new sandpa- per. Make sure to wrap the sandpaper tight and try to keep the gaps to a minimum.

6.Tape both ends with 3⁄4" strapping tape (Figure 18), making at least two complete passes so that the second layer is directly on top of the first.
