Belt Replacement and Adjustment
1. Disconnect machine from the power source.
2. Open end gear cover, remove lower rear cover and lower side cover.
This will expose the motor and V-belts.
3. Loosen hex nut (A, Fig.20). Place scrap piece of wood under motor to

4. Remove belts. Install new belts onto pulleys.
5. Lift up on motor and remove temporary blocking.
6. Tension belts by loosening nut (B, Fig.20) and tighten nut (A, Fig.20)
until light finger pressure causes approximately 3/4" deflection on each
belt.
7. Install covers and connect lathe to the power source.
Aligning Tailstock to Headstock
1. Fit a 12" ground steel bar between centers of the headstock and
tailstock (See Fig.21).
2. Fit a dial indicator to the top slide and traverse the center line of the
