Closing Power Control Figure 7

For UNI-J7500 Series Only Set closer to desired size. For

recommended sizes, refer to the Power Adjustment Chart below.

Install closer per instructions with proper pre-load applied to arm then adjust spring power. Power adjustment will not work properly if closer spring is not pre-loaded. To increase power, use 11/16" wrench to turn power adjustment nut clockwise. To decrease power, turn nut counter clockwise.

DO NOT use a power drill or driver to turn adjustment nut. This will damage closer and void warranty.
