a. The Cables should be tightened to the point just before the Top Plate lifts off the stack. In
other words, if the Top Plate is not resting on the stack, you will need to add length, or, if there
is slack in the cables, you will need to shorten the cables. There are several adjustment
points. If only minor adjustments need to be made, you can adjust the Screw ends on the Top
Cable (at the Top Plate), the Low Cable (where it screws into the Pulley Block), or the Bench
Press Cable (where it screws into the Pulley Block with Stopper). These ends of these
cables must be screwed in at least 1/3 of their length for safety purposes. Once you are
done with these adjustments, lock them into place using the jam nuts.
b. Broader adjustments are made at the Adjustable Pulley Block (13). Moving the bottom pulley
toward the center decreases length (takes up slack). Conversely, moving the bottom pulley
outward gains cable length.
c. Once the cables have been adjusted to remove all slack, adjust the Adjustable Stoppers in the
Top Frame to where they just touch the Adjustable Pulley Block (13). The Adjustable Stoppers
welded on top frame aid in the function of the gym by eliminating the need to engage all
cables in any given exercise routine.
