Thankfully, I have a wonderful contractor who is patient and kind and willing to teach me things. Not only did the hardware store forget to give me a power cord, they did not show me how to load the blade correctly. -_- I am not going to name names, because in the past this particular hardware store has been great in terms of rentals, I think I just got a grumpy guy having a bad day (who in turn wasted a ton of my time...but I digress...). If it weren't for my contractor, I would have spent hours moving a 150 pound machine around the kitchen just to make a lot of noise.
