Side-to-Side Vertical Adjustment
If the Selector Stem contacts the inside of the Weight
Stack during use or the Weight Pin becomes difficult to
insert in the Weight Stack, the Selector Stem may be
out of alignment vertically side to side

.

Adjust the
Selector Stem by taking these steps:
Caution: Performing these steps requires two
people.
A. Pull the Selector Stem and Top Cap up to expose
at least five Selector Stem holes.
B. Insert the Weight Pin near the base of the Selector
Stem to hold it in place.
C. To center the Selector Stem, loosen the socket cap
bolt that attaches the Top Cap to the U bracket.
D. Once the Selector Stem is centered, retighten the
socket cap bolt securely.
E. Lower the Selector Stem into the Weight Stack.
Test the movement of the Selector Stem inside the
Weight Stack.
F. Make certain that the Weight Pin can be inserted
into every hole in the Weight Stack. If the Selector
Stem continues to contact the plates, repeat steps
A through E until the Selector Stem slides through
the Weight Stack without contacting the plates.
After completing the adjustments, fill out the warranty
card and mail it in.
