Ok.This machine is not for everyone. Other machines like it cost twice as much. The instructions are lacking, as well as accurate explanation of the operation of the machine, so if you buy it as I did you are going to get that information elsewhere. Is the machine precision made?No.Does it wobble, yes.Does that affect the function of what the machine needs to do?No. Do your home work, Familiarize yourself with safe operation,learn how the controls work in an open space, feed the cable in and out.Mark the machine cable in and out control handle yourself ( no markings in casting).Never switch the motor into reverse from forward.Reverse motor is only meant to be used with the foot switch for when you bind up the cable( and eventually it will happen).Cable in and out is always done with the motor in forward by using the lever to switch between forward and reverse ( a gear in the lever assembly changes the cable feed direction from forward to reverse with the handle with the motor always in forward motion.) One really important thing you will find nowhere but here is this-The drum with the cable revolves at about 400 rpm ( the motor 1800 ) so that means the cable travels out 7 feet per minute you hold down that foot switch.If you have a blockage at 21 feet it will take 3 minutes for it to reach it before actually feeling any resistance, once you do, you may have to shift into neutral for the cable to cut and relax, engage it in forward a bit more, and so on. I will post more as I use it. But for now, for what’s in the maket for the price, this was the best value- stay tuned. (You can always put the machine in neutral and manually pull the cable into your pipe,but you won’t have a clue how far you are into your pipe. With the 3 minute feed in I knew I was about 21 feet into my pipe.)
