I had a hard time getting the unit to start initially. Keep in mind little tricks like if it won't start on choke move it into run and try to start it there. Manual doesn't tell you that. I was looking for all kinds of problems like with the spark plug or something when really I just needed to move it in to run to get it to start. I found that the line to the spray gun would not stop kinking even though I wasn't doing anything to make it kink. I purposely uncoiled both my garden hose and the line to the spray gun before even starting and somehow the spray gun line continually kept kinking over and over again and causing a problem for me. I assume it's just because it's new, but it was very problematic on the first use. Also, the manual doesn't warn you that it's best to run the spray guns line underneath the machine so that you don't end up accidentally burning the line and ruining it on one of the hot parts of the machine, which is what I did on the very first use. I can't find anywhere in the owner's manual that warns you about that. When you're pressure washing the house or anything else, you're not looking back at the machine to verify where the line to the gun is. Somehow the line to my gun ended up touching one of the hot parts on the top of the machine and destroyed my line on the first use. Super irritating and discouraging and nothing that I would have thought of as a first-time user that I needed to be careful of. Run your line either behind and to the left of the machine, even though it does not naturally come off the machine that way, or run it underneath the machine to ensure you don't accidentally while you're working away end up with the line touching one of the hot parts of the machine that are literally right next to the where the line naturally comes off of the machine. Also it isn't designed with a super great weight factor. It's got this suction cup that seems great initially but it doesn't in any way hold it to the ground when you're trying to start it. When I was having trouble starting it initially almost every time I pulled the recoil handle to try to start the engine the machine was jumping all over the place. It didn't matter if I tried to position my body up against the machine or if I tried to put my foot on the machine somewhere. It really just did not want to sit still when the recoil handle was pulled. The user manual also says it comes with a spark plug wrench; it does not. I'm going to have to buy a new socket wrench set because the set I have doesn't go up to a size big enough for this particular spark plug. Also, one of the nuts that I did not personally have to touch in any way to assemble the machine came off during the first use. Thank God it came off in my cement carport and not in the grass or I would have never noticed and never found it.
