3.Apply moderate pressure on the idler pulley (see Figure 92) toward the front of the lathe while turning the tensioning bolt counterclockwise to lower the idler pulley and increase belt tension.

The correct amount of belt tension is when there is approximately 1⁄4"– 3⁄8" deflection with moderate pressure applied to the belt between the pulleys (see Figure 93).

4.When the belt tension is correct, continue applying pressure on the idler pulley as you re-tighten the pivot block hex nut to secure the tension setting.

5.Re-check the tension on both belts, and if necessary, repeat this procedure until the correct belt tension is attained.

6.Close the end cover before re-connecting the lathe to power.

DO NOT overtighten belt tension. This could cause the machine to run hot and cause damage to the motor and bearings.
