Weight stack label and lubrication instructions:

1. Wipe front surface of weight stack with rubbing alcohol and wipe dry.

2. Peel o back sheet (adhesive side) from label and make sure that the label remains attached to the application

tape.

3. Line up left edge of label sheet with outside edge of weight holes.

4. Line up the  rst label to hole on top plate.

5. Make sure label is straight and slowly press into place.

6. Gently remove application tape and rub each label  rmly against the weight stack.

7. Allow labels to stand for 2 days to allow adhesive to cure fully.

8. Open the lube package provided and apply a thin  lm of lubricant around the  rst 3 inches of the guide rods

above the top plate.

9. After the cables are installed, do a set of reps to spread the lubricant thoroughly.

Cable Adjustment

1. Adjustments can be made in the area pointed out (FIGURE B) to set the correct tension on the cable.

2. Upon completion of assembly, the TOP PLATE (16#) does not sit on top of the  rst WEIGHT PLATE (#15), push the

TOP PLATE (#16) down, insert the SELECTOR PIN (#12) and perform several repetitions. This will self-adjust and

re-align the cable system.

3. After completing the previous step, the TOP PLATE (#16) still does not sit on top of the  rst WEIGHT PLATE (#15)

or if there is excess slack in the cable system, loosen regular nut (#32) and adjust split hex tap bolt (#55) in/out

to give the cable proper tension (taut). Once achieving the proper tension, re-tighten regular nut (#32).
