The Headstock
The headstock includes a Gear box (E) which con- tains gears and a belt drive. The gears are con- trolled by controls (F), (G), and (H). The belt drive transmits the motor power to the drive system of the machine.
1.The motor and drive belt are installed and ad- justed when delivered. However, you should check the adjustment of the drive belt before using this lathe.
2.Check the belt tension by pressing in the middle with your finger.You should be able to depress it approximately 1/2 inch. If the belt is too tight, it will wear the bearings, and if too loose, it will slip on the pulleys and wear out prematurely.
3.If it is necessary to adjust the belt tension, do so by adjusting the bolt and locknut assembly on the underside of the motor.The motor mounted on the back of the headstock.
4.Four additional change gears are included for use in cutting metric and SAE threads. Refer to the lead screw chart on the headstock for the gears required for the thread pitches you want.
Please refer to the section on threading for more information.
