Reviewed on   -   Purchased on 10/14/2014
The add oil before starting label was only on the pull out line and not on the key switch.  I was smart enough to know one needs to add oil but this could be overlooked easily.   It starts right up and is quieter than I  expected. Delivery man had trouble getting up my hill and I had to tow him. He was warned to use a box truck but didn't listen. The fee should be returned to me but I won't hold my breath. Please don't use that company again if I order from your company in the future.
