2. Selector Stem Adjustments
To prevent the Selector Stem from contacting the inside
of the Weight Stack when the machine is in use, you
need to check the vertical angle of the Selector Stem
(steps A and B). If the stem slides smoothly without
contacting the inside of the weight plates, assembly of
the unit is complete.
Caution: Performing the following tasks requires
two people.
A. Remove the Weight Pin from the Weight Stack.
B. Perform an exercise using each part of the S3.45.
When the base of the Selector Stem is clear of
the Weight Stack, observe the position of the
Selector Stem.
The following sections describe how to adjust the
Selector Stem when contact does occur.
The Selector Stem can be adjusted forward or
backward, depending on the area of contact.
Forward Angle Adjustment
When the Selector Stem angles forward (toward the
seat) and contacts the inside of the Weight Stack
during use, adjust it by taking these steps:
Caution: This adjustment requires two people.
A. Completely disassemble the Cap Plate,
Selector Stem, and Cable Clamp.
B. Thread Allen head set screw into the hole closest
to the top of the U end of the cable and turn
clockwise until the end of the screw is flush with
the inside surface of the clamp.
C. Turn the set screw clockwise another one-half turn
(see diagram).
