MAINTENANCE 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. 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 1 (91) that connects the end of a cable to a "U"- bracket (50). • See drawing 1. Re48mm Bolt (64) from the Cable Trap (68), the 90mm Pulley (63), the two Half Finger Guards (66), and a "U"-bracket (50). Reattach the Pulley, Cable Trap, and Finger Guards to the other hole in the "U"-bracket. Make sure that the Cable Trap and Finger Guards are oriented as shown and that the cable and Pulley move smoothly. 90 66 68 50 91 66 63 64 • See drawing 2.

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. 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
(91) that connects the end of a cable to a “U”-
bracket (50).
•
See drawing 1.
Re48mm Bolt (64) from the
Cable Trap (68), the 90mm Pulley (63), the two
Half Finger Guards (66), and a “U”-bracket (50).
Reattach the Pulley, Cable Trap, and Finger
Guards to the other hole in the “U”-bracket.
Make
sure that the Cable Trap and Finger Guards
are oriented as shown and that the cable and
Pulley move smoothly.
•
See drawing 2.
Remove the M10 Nylon Locknut
(90) and the M10 x 48mm Bolt (64) from the
Cable Trap (68), the 90mm Pulley (63), the two
Half Finger Guards (66), and the two Pulley
Plates (51). Reattach the Pulley, Cable Trap, and
Finger Guards to the next closer hole to the cen-
ter of the Pulley Plates.
Make sure that the
Cable Trap is oriented to hold the cable in the
groove of the Pulley, that the Finger Guards
are oriented as shown, and that the Cable and
Pulley move smoothly.
•
See drawing 3.
Loosen the M12 Nut (49) on the
Weight Cable (110). Tighten the Cable into the
Weight Tube (not shown) until the slack is
removed from the Cable. Retighten the M12 Nut
