SM51 Unpacking & Assembly Instructions 7. Mount adjustable pulley brackets. When shipped, the adjustable pulley brackets look like the ones shown in Figure 13. The bolts need to be removed and the bracket needs to be positioned so that the top of the bracket is in the top hole as shown by the arrow in Figure 13.

SM51 Unpacking & Assembly Instructions INSTALLING THE CABLES The SM51 uses five cables. There are three different types of cable used on the SM51. They are: 1. Adjustable crossover cables (ball end cables) (2). 2. Low row cable (the long cables) (1).

SM51 Unpacking & Assembly Instructions ADJUSTABLE CROSSOVER CABLE ROUTING Once you’ve removed the pulleys as described previously, route the adjustable crossover cable on the 4-stack cell as shown in Figure 17. The crossover cable is routed at the factory on the 1 stack cube (shown at right in Figure 17).
SM51 Unpacking & Assembly Instructions Figure 18. Adjustable crossover cable end detail. Using a 7/8” wrench, tighten the jam nut onto the adjustable pulley threads as shown in Figure 18. Place a rubber cap on the top of the cable as shown in Figure 18 (right).
