ADJUSTMENTS
To adjust the length of the Primary Arm, you can use any two of the holes that line up with the two
holes in the pivot plate that mounts to the top of the output shaft. You will need to cut off any excess
material that extends off the back side. Install the two bolts and tighten them securely.
To adjust the Secondary Arm, there are two set screws under them ARM ENDS that can be loosened
to allow that section to be made shorter. It may be necessary to cut the aluminum tube to a shorter
length for some installations.
