Another "Tip from Ted" this time regarding making sure the Imitator is sitting upright when on the bottom. Make sure when setting the unit on the bottom that its sitting upright so the string is coming out of the top. When setting it down, it goes down at an angle due to the string being on one side of the Imitator. If the Imitator lays over on its side, the action string would be on the bottom side in the mud and would also be coming out of the hole at an additional 90 degree angle thereby creating unnecessary drag on the motor and shaft. A slow torque on the motor won't trip the fuse. Making sure the unit is upright may save you some trouble (and me money :-)).
Here's a video showing the proper bottom placement of the Imitator.
