black and decker 7447 belt sander manual Related Question:
How much tension should a belt sander have?
Most wood sanding applications (such as mould sanding using narrow cloth belts) require a belt tension of approximately 40 psi. However, there are some special exceptions. For example, abrasive planing operations using coarse grits typically demand belt tension in the range of 70 to 90 psi.
What may happen to an operator who reaches across the rotating sanding disc to turn the sander off?
Do not reach across the sanding disc to turn the sander on or off. Your arm or hand may touch the edge of the rotating disc and cause a serious cut or entanglement.
In which direction should you sand an object using the belt sander and why?
Begin on a flat surface and move the sander toward the uneven surfaces. Moving diagonally front to back and side to side will help average out the amount of cut that the belt is making. You do, however, have to actually set the sander on the workpiece, hold the handle, and pull the trigger.
Why does the sandpaper keep breaking on my belt sander?
There are pretty much two reasons they can be breaking so quickly: the belts are old stock (or have been stored in humid or hot locations) or the tension is too high. Or both.
