Replacing V-Belts

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.

To ensure efficient transfer of power to the spin- dle, make sure the V-belts are always properly tensioned and in good condition.

If a V-belt is worn, cracked, or damaged, replace both V-belts at the same time to ensure belt ten- sion is even between them, which reduces the risk of premature wear on either belt.

4.Check the deflection of the V-belts by apply- ing moderate pressure midway between the pulleys, as illustrated in Figure 82. When properly tensioned, there should be approxi- mately a 3⁄4" deflection.

tension.

—If there is not a 3⁄4" deflection of the V-belts, loosen each of the top adjustment hex nuts, then raise or lower the motor by turn- ing each hex nut underneath the motor mounting plate by the same amount until the V-belt tension is correct.

5.When you are satisfied that the V-belts are properly tensioned, make sure all adjustment hex nuts are tight, then replace the left and rear lower access panels and secure the left side door.
