Sanding Belt
Tracking
The sanding belt must track in the center of the top pulley to avoid damaging itself and the machine during use.
To adjust the sanding belt tracking:
1.DISCONNECT SANDER FROM POWER!
2.Remove the sanding belt side cover and rotate the wheels by hand to make an initial check of the belt tracking.
3. Slowly adjust the tracking adjustment knob as necessary and repeat Step 2 until the sanding belt tracks in the center of the top pulley, then replace the belt side cover.
4.Connect the sander to power, turn it ON and be ready to turn it off immediately if the belt begins to move off the wheel.
5.Observe the sanding belt as it moves over the top pulley (see Figure 12).

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 abrasive types into different classes, and shows which grits fall into each class.
Grit | Type |
60Coarse

220 | Very Fine |
The general rule of thumb is to sand a workpiece with progressively higher grit numbers, with no one grit increase of more than 50.
