NOTE: DIAGRAMS AND ILLUSTRATIONS ARE NOT TO SCALE
Tools Needed:
7/16” wrench
Adjustment Procedure:
Step 1 Open the surround access door. Inspect the tension or lack of
tension while opening the door to determine if it should open
easier or tighter.
Step 2 With access door open you will see the ball screw and jam nut
on the surround backing plate near the top surround piece as
seen in picture A. Using a 7/16” wrench, loosen the jam nut on
the ball screw as shown in Picture B.
Step 3 Once this jam nut is loose you can then adjust the ball screw
for more or less tension using your fingers as seen in Picture
C. Turning the ball screw counter-clockwise, as you are look-
ing at it, will give you less tension and turning the ball screw
clockwise will give you more tension when opening and closing
the surround access door. Picture D is showing the ball screw
adjusted down for additional tension.
Step 4 You can then test close the surround access door to ensure it
has proper tension. Readjust if needed.
Step 5 Once the proper tension is achieved, hold the ball screw with
your fingers, then using a 7/16” wrench tighten the jam nut,
clockwise (SNUG ONLY, DO NOT OVERTIGHTEN).
