Safety First
Augers are large, and safety comes first. If possible, have someone help you keep the auger straight. Gloves, eye protection and steel toed boots are recommended when using a post auger.
Mark Locations
Mark the locations where the wooden posts are going to be placed. By doing this, you will make the actual digging of the holes much quicker and handling the auger much easier.
Hold Auger Straight
Hold the earth auger as straight as you can. Keep both hands on the handles and guide the auger into place.
Let Auger Do Work
When you build a wooden fence with a earth auger it is important to let the auger do the work. Set it in the place you want the hole dug and let the bit dig into the ground. You may need to lift the auger occasionally to free the bit of dirt and rocks.
