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 25),

push on the middle of the v-belt. the correct
v-belt tension is achieved when the v-belt
can be deflected

to make the gauge blocks:

1. edge joint the concave edge of the 2x4 flat on

a jointer, as shown in

the opposite side to square up the two edges
of the 2x4, as shown in

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.
