How do I tighten the belt ? I tried to pull the motor and tighten the lock nut but it never tightened… Any suggestions ?
You Don’t
The belt on this machine is loose so that it can act as a clutch when the motor starts up. The motor then pivots to tighten the belt.
Here is a service manual if you need to do further work on the machine.
