NOTE: DIAGRAMS AND ILLUSTRATIONS ARE NOT TO SCALE
Tools Needed:
7/16” wrench
Flat End Screwdriver
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  With the access door open you will see the ball screw latch as
shown in Pictures A and B. Using a 7/16” wrench, loosen the
jam nut on the ball screw assembly as shown in Picture F.
Step 3 Once this jam nut is loose you can then adjust the ball screw for
more or less tension using your hand Picture E or the flat end of
a screwdriver as seen in Picture D. Turning the screw counter-
clockwise, as you are looking at it, will give you more tension
and turning the screw clockwise will give you less tension.
Step 4 You can then test close the surround access door to ensure it
has proper tension. Readjust if needed.
Step 5 Once proper tension is achieved, hold the ball screw with either
your hand or a flat screwdriver, then using a 7/16” wrench
tighten the jam, counter-clockwise (SNUG ONLY, DO NOT
OVERTIGHTEN).
