V-Belt Tensioning/
Replacement
NOTICE
After the first 16 hours of use, the V-belts
will stretch and seat into the pulley grooves.
The V-belts must be properly re-tensioned
after this period to avoid severely reducing
their useful life.

Note: The V-belts are correctly tensioned
when there is approximately
3
⁄4" deflection
when moderate pressure is applied to them
midway between the pulleys, as illustrated in
Figure 33.
