Primary precautions -
 

Hey Brenton, It looks like everyone has pretty well covered the primary precautions you need to watch for in changing out your plugs. Just take your time and you’ll be fine.

I see you’re down under. I’ve enjoyed a couple of business trips to Australia over the years. The Hunter Valley was a beautiful area and up around western Queensland reminded me of Texas in many places. Each visit was filled with lots of once in a lifetime experiences - I even saw a wild platypus swimming in a creek while passing through the Eungela national park. One trip back from Alice Springs coincided with a cyclone that had blown in north of Cape York. I sunk a rental car while returning across what had been a dry canyon only minutes before. Man - “the rain falls mainly on the plains” in Queensland. I still have my “Capt Submarine” cap some of the Mackay locals gave me.

Good Luck on your project - Michael :)
