MAINTENANCE Inspect and tighten all parts each time the weight system is used. Replace any worn parts immediately. The weight system can be cleaned using a damp cloth and 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. If any slack is felt when using the weight stack closest to the ab upright, both the High Cable (85) and the Low Cable (86) will need to be tightened. If any slack is felt when using the other weight stack, the Rear Cable (87), the Press Cable (88), and the Butterfly Cable (89) will need to be tightened. To tighten the cables, first insert the weight pin into the middle of the weight stack. Slack can be removed from these cables several ways: • See drawing 1. Tighten the M8 Nylon Locknut (40) that connects the end of the Press Cable (88) to the Large "U"-bracket (84). • See drawing 1. Remove the M10 Nylon Locknut (42) and the M10 x 48mm Bolt (50) from the Cable Trap (80), 90mm Pulley (82), and Large "U"-bracket (84). Reattach the Pulley and Cable Trap to the other hole in the Large "U"-bracket. Make sure that the Cable Trap is in the proper position and that the Cable and Pulley move smoothly. • See drawing 2. Tighten the M8 Nylon Locknut (40) that connects the end of the High Cable (85) to the Small "U"bracket (32). 1 82 80 42 84 50 40 88 2 32 85 87 32 40 The Rear Cable (87) can be tightened in the same manner. • See Drawing 3. If you feel additional slack while using the weight system, the Low Cable (86) and the Press Cable (88) can be tightened further. Remove the two M10 x 48mm Bolts (50), the two M10 Nylon Locknuts (42), the two 90mm Pulleys (82), and the two Cable Traps (not shown) from the Pulley Plates (31). Reattach the upper Pulley without the Cable Trap. Reattach the lower Pulley to the higher hole in the Pulley Plates without the Cable Trap. Keep the Cable Traps for future use. Make sure that the Cable and Pulley move smoothly. Do not overtighten the cables. If the cables are overtightened, the top weight will be lifted off the weight stack. 3 82 50 82 86 or 88 40 42 31 If a cable tends to slip off the pulleys often, it may have become twisted. Remove the cable and re-install it. If the cables need to be replaced, see ORDERING REPLACEMENT PARTS on the back cover of this manual. 25
