• Adjustments can be made in the above locations to set the correct amount of tension in the cables.
• If upon completion of assembly, the HEAD PLATE (22) does not sit on top of the first WEIGHTPLATE (20), push the HEAD PLATE
(22) down, insert the WEIGHT STACK PIN (23) and perform several repetitions. This will relax the cable system and prevent the
HEADPLATE (22) from lifting up. SeeFIGURE 16.
• If after completing the previous step, the HEAD PLATE (22) still does not sit on top of the first WEIGHTPLATE (20) or if
there is excess slack in the cable system, adjust the threaded ends of the CABLES attached to the HEAD PLATE (22) accordingly and
retighten the jam nuts. See FIGURE 16.
• For maximum performance, the HEAD PLATE (22) should just barely sit on the top WEIGHTPLATE (20).
