Before using the weight system, pull each cable a few times to make sure that the cables move smoothly over the pulleys.
ADJUSTMENTS This section explains how to adjust the weight system. See the EXERCISE GUIDELINES on page 26 for important information about how to get the most benefit from your exercise program. Also, refer to the accompanying exercise guide to see the correct form for each exercise. Make sure all parts are properly tightened each time the weight system is used. Replace any worn parts immediately. The weight system can be cleaned with a damp cloth and a mild, non-abrasive detergent. Do not use solvents.
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. See drawing A. Slack can be removed by moving the 90mm Pulley (38) and Cable Trap (91) to a higher set of holes in a Double "U"-Bracket (56). Remove the M10 Nylon Locknut (70) and the M10 x 50mm Bolt (62) from the Cable Trap, the Pulley, and the Double "U"Bracket.
WEIGHT RESISTANCE CHART The chart below shows the approximate weight resistance at each exercise station. "Top" refers to the 6 lb. top weight. The other numbers refer to the 12.5 lb. weight plates. Weight resistance shown for the butterfly arm station is for each butterfly arm. Note: The actual resistance at each station may vary due to differences in individual weight plates as well as friction between the cables, pulleys, and weight guides. WEIGHT HIGH PULLEY (Ibs.)

CABLE DIAGRAMS The cable diagrams below show the proper routing of the High Cable (45), the Butterfly Cable (46), the Low Cable (47), the Leg Press Cable (95), and the Leg Lever Cable (96). Use the diagrams to make sure that the cables and the cable traps have been assembled correctly, tf the cables have not been correctly routed, the weight system will not function properly and damage may occur. The numbers show the correct route for each cable.

EXERCISE GUIDELINES THE FOUR BASIC TYPES OF WORKOUTS PERSONALIZING Muscle Building To increase the size and strength of your muscles, push them close to their maximum capacity. Your muscles will continually adapt and grow as you progressively increase the intensity of your exercise. You can adjust the intensity level of an individual exercise in two ways: • by changing the amount of weight used • by changing the number of repetitions or sets performed.
Rest for a short period of time after each set. The ideal resting periods are: • Rest for three minutes after each set for a muscle slowly as you stretch and do not bounce. Ease into each stretch gradually and go only as far as you can without strain. Stretching at the end of each workout is an effective way to increase flexibility. building workout. • Rest for one minute after each set for a toning workout. STAYING MOTIVATED • Rest for 30 seconds after each set for a weight loss workout.
