The gauge blocks described here will be required to complete most of the service procedures in this section.

To make the gauge blocks:

1.Edge joint the concave edge of the 2x4 flat on a jointer, as shown in Figure 22.

2.Place the jointed edge of the 2x4 against the table saw fence and rip cut just enough off the opposite side to square up the two edges of the 2x4, as shown in Figure 23.

3.Cut the 2x4 into two even pieces to make two 36" long wood gauge blocks.

Note: Steps 1 & 2 can be skipped, but having these wood gauge blocks at an even height is critical to the accuracy of your overall adjust-

ments.

Tension

A new V-belt often stretches and loosens up dur- ing the first 16 hours of use. After this period, it should be inspected and re-tensioned if neces- sary.

Proper tension is important for optimum power transmission. However, too much tension may cause premature bearing failure.

To test V-belt tension:

1.Remove the right handle and side panel.

2.Using a straightedge and ruler (Figure 24), push on the middle of the V-belt. The correct V-belt tension is achieved when the V-belt can be deflected 1⁄2"–3⁄4" with moderate pres- sure.

straightedge and a ruler.

3.Reinstall the side panel and handle.
