The use of the remaining parts will be explained in ADJUSTMENTS, beginning on page 21 of this manual. Before using the weight system, pull each cable a few times to be sure that the cables move smoothly over the pulleys. If one of the cables does not move smoothly, find and correct the problem.
ADJUSTMENTS The instructions below describe how each part of the weight system can be adjusted. Refer to the exercise guide accompanying this manual to see how the weight system should be set up for each exercise. IMPORTANT: When attaching the lat bar or nylon strap, make sure that the attachments are in the correct starting position for the exercise to be performed. If there is any slack in the cables or chain as an exercise is performed, the effectiveness of the exercise will be reduced.
ATTACHING AND REMOVING THE SEAT 8 40 To attach the Seat (13), set the bracket on the Front Seat Frame (36) onto the indicated pin on the Front Upright (42). Attach the Front Seat Frame to the Front Upright with the 5/16” x 2 3/4” Carriage Bolt (14), 5/16” Washer (8) and the Seat Knob (40). 36 13 14 42 For some exercises, the Seat (13) must be removed. First, be sure that the chain is not attached to the leg lever.
WEIGHT RESISTANCE CHART This chart shows the approximate weight resistance at each weight station. “Top” refers to the 6.5 lb. top weight. The other numbers refer to the 12.5 lb. weight plates. The butterfly arm resistance listed is the resistance for each butterfly arm. The actual resistance at each weight station may vary due to differences in individual weight plates, as well as friction between the cables, pulleys, and weight guides.
TROUBLE-SHOOTING AND MAINTENANCE TIGHTENING THE CABLES Woven cable, the type of cable used on the weight system, can stretch slightly when it is first used. If there is slack in the cables before resistance is felt, the cables should be tightened. If any slack is felt when using the front weight stack, both the High Cable (58) and the Low Cable (23) will need to be tightened.
CABLE DIAGRAMS The cable diagrams on these pages show the proper routing of the High Cable (58), the Low Cable (23), the Military Press Cable (72), and the Leg Press Cable (78). Use the diagrams to be sure that the four cables and the cable traps have been assembled correctly. If the cables have not been correctly routed, the weight system will not function properly and damage may occur. The insets show the proper positioning of the cable traps.
