Today I'm gonna show you how to adjust a Hunter Rotary head using this little key. So let's come over here. So you got two holes here.This front hole adjusts length of spring and this left hole adjusts left rotation. We use the metal part of this key, put it in the front hole, you’lI feel it kind of a groove in. If I turn it clockwise, it's gonna become a wider, but a shorter spray. And then if I turn it counterclockwise, it's gonna become a thinner and further out spray. Then if we take the bottom part, put it in this left hole again you'll feel it groove in. If I turn it clockwise, it's gonna go more left. If I turn it counter clockwise, it's gonna go less left. Right is fixed. You need to grab it by the base with a channel lock or some gloves. But the left you can make it do a 360.
