STEP 10:

• SECURELY assemble the GUIDE ROD SUPPORT (5) to the TOWER (1) using four RH CAPS (33), two 3/8 X 2-1/2” BOLTS
(9), four 3/8” RH WASHERS (16) and two 3/8” LOW HEIGHT LOCK NUTS (14) as shown in FIGURE 10.

nut securely. See FIGURE 10.

• Insert the WEIGHT STACK PIN (18) into the WEIGHT STACK as shown in FIGURE 10.

• If the HEAD PLATE (7) does not sit on top of the first WEIGHT PLATE (28), push the head plate down, insert the SELECTOR PIN
(18) and perform several repetitions on the machine. This will relax the cable system and prevent the HEAD PLATE (7) from
lifting up.

• If after completing previous step the HEAD PLATE (7) still does not sit on top of the first WEIGHT PLATE (28) or if there is
excess slack in the cable system, adjust the threaded end of the CABLE accordingly and retighten the jam nut.
