Had to locktight bolts to keep from loosening bolts

Good tool, arrived today like Amazon said it would. Out of the box everything was there and in good shape. I read the directions like all should and with the tools supplied I went over every bolt had to tighten the bolts on handles but here is a tip. The nuts was started and they are self locking but only tighten to expose a few threads or you will mess up you handles. This is a strong vibratory machine handles should be free. Mix you gas 25:1 and they give you a measurement bottle and a nice funnel. Lay machine on the ground tank up use funnel and just fill to bottom of neck of tank.To Put the bit in pull latch rotate the pin stick tip of your finger and feel the notch in the latch insert the bit notch up and rotate the pin and release the latch it's spring loaded. Prime the carb and turn choke off.pull starter should try to start in 2-3 pulls flip choke off should start 1st pull. Make sure you close throttle before start. Throttle is supposed to be stiff it will stay on low and high by its self it's not spring loaded. Let it idle to warm. When you place your bit to the the pavement. The throttle is in the position on left lower handle because you let the machine lay against you right leg only engage throttle by gently lay machine against the thigh of you leg and let the machine do the work. I can run it with one hand it's that easy. If you open it up you better have you goggles on that's supplied. And you will see how strong it is. But you don't have to run it wide open just 1/4 to half throttle. It's from China and by hell it will dig it's way back and take you with it. You'll know what I mean if and when you throttle it wide open!Keep in mind you will have to grab throttle to stop it. Buy it. It's a good machine if you know how to operate it. It's not for a ( Green Horn)
