Brake Adjustment
1. The brake adjustment has been made at the factory, so that it is not to re-adjust. However, in case of insuf-
ficient brake operation, perform the upper procedure.
2. Overtightening of the adjustment bolt will cause poor brake performance.
3. Undertightening of the adjustment bolt will cause continuous bracking and, thereby, cause the problems of
the motor during the spin cycle.
