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.
