TROUBLESHOOTING

Make sure all parts are properly tightened each time the weight bench is used. Replace any worn parts immediate-
ly. The weight bench 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 bench, can stretch slightly when it is first used. If there is
slack in the cables before resistance is felt, the cables should be tightened. Slack can be removed from the
cables in several ways:
See drawing 1. To tighten the cables, remove the
M10 Nylon Locknut (97) and the M10 x 45mm Bolt
(112) from the lower 90mm Pulley (90), Cable Trap
(125), and the Pulley Plates (72). Reattach the Pulley
and the Cable Trap between a set of holes closer to
the center of the Pulley Plates with the Bolt and
Locknut. Make sure the Cable Trap is oriented to
hold the Low Cable (82) in the groove of the
Pulley.
See drawing 2. Additional slack can be removed
from the cables by tightening a cable into the M6
Nylon Locknut (124) inside a Cable End Clip (85). To
do this, pull the Clip Cover (84) back and use pliers to
tighten the Locknut. Replace the Cover.
Do not overtighten the cables. If a cable slips off the pulleys repeatedly, 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.
