HRX 075 Pattern Adjustment

The HRX 075 is preset for 180-degree operation.  The pattern can be adjusted for operation between 40 and 360 degrees.

  1. Turn the top of the head all the way to the left until it stops and then all the way to the right. The top of the head must be in this position to make adjustments.
  2. Insert the plastic end of the adjustment wrench into the pattern adjustment hole (circle with plus and minus signs on either side).
  3. Turn clockwise to increase rotation; counterclockwise to decrease rotation. Each full turn  increases/decreases rotation by 90˚
