Substrate Technology guarantees that its machines and products are without manufacturing defects. The warranty period on machines is one (1) year from the date of sale and the variable speed drive carries a two (2) year warranty from the date of sale. Substrate Technology will replace any part that is defective at its own cost within the warranty period. This warranty does not cover wear items or instances of abuse or neglect.
When transporting P/M machines, it is mandatory to move all pocket weights to the head of the grinder, or off of the machine. Failure to do so will result in damage to the handle frame that is not covered under warranty.
