Make sure that all parts are properly tightened each time the weight system is used. Replace any worn
parts immediately. To clean the weight system, use a damp cloth and a mild, non-abrasive detergent; do not
use solvents to clean the weight system.
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 the cables in three ways:
See the inset drawing. Tighten the M6 Locknut (33)
that connects the Low Cable (53) to the
U-bracket (45).
To further tighten the cables, remove the M10
Locknut (56) and the M10 x 50mm Bolt (95) from the
two Half Guards (43), the U-bracket (45), the Cable
Trap (50), and the Pulley (48).
Reattach the Pulley (48), Cable Trap (50), and Half
Guards (43) to the other hole in the U-bracket (45).
Make sure that the Cable Trap is in the proper
position and that the Low Cable (53) and the
Pulley move smoothly.
Do not overtighten the cables. If the cables are overtightened, the top weight will 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
reinstall it. If the cables need to be replaced, see ORDERING REPLACEMENT PARTS on the back cover of this
manual.
If there is still slack in the cables, loosen the M12
Nut (13) on the High Cable (55).
Next, tighten the High Cable (55) into the Weight
Selector (24) until the slack is removed from the
High Cable.
Then, retighten the M12 Nut (13) against the Large
Washer (17).
