MAINTENANCE
Make sure all parts are properly tightened each time the weight system is used. Replace any worn parts imme­
diately. The weight system can be cleaned with a damp doth 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 MS Nylon Locknut
(115) that connects the end of a cable to a “U”-
bracket (50).
• See drawing 1. Remove the M10 Nylon Locknut
(114) and the M10 X 52mm Bolt (102) from the
Small Cable Trap (48), 90mm Pulley (39), the two
Half Finger Guards (42), 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
(114) and the M10 x 52mm Bolt (102) from the
Small Cable Trap (48), the 90mm Pulley (39), the
two Half Finger Guards (42), and the two Pulley
Plates (51). Reattach the Pulley, Cable Trap, and
Finger Guards to the next closer hole to the center
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 orient­
ed as shown, and that the Cable and Pulley
move smoothly.
See drawing 3. Loosen the Ml 2 Nut (128) on a
cable. Tighten the cable into the Weight Tube (not
shown) until the slack is removed from the cables.
Retighten the Ml 2 Nut against the Ml 2 Washer
(129).
Do not overtighten the cables. If the cables are overtightened, the top weight wili be lifted off the weight
stack. 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.
