How to replace the time relay in a magnetic field polishing machine

Now I’ll show you how to replace the time relay. If the time relay is broken, follow these steps. First, remove all screws around the panel and flip the panel open. Unplug the connector directly. Press the two buckles on both sides downwards and pull out the old relay. Take the new time relay, open its buckles, insert it by aligning the terminals. Align the protrusion with the positioning slot and lock it in place. Close the panel and tighten the screws. The replacement is finished.
