Trouble-shooting and Maintenance

Inspect and tighten all parts each time you use the training system. Replace any worn parts immediately. The training 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 training sys- tem, 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 (39) under the third Weight (26) from the top. Next, loosen the 1/2Ó Plain Nut (68) securing the bolt at the end of the High Cable (73). Tighten the bolt two turns into the Weight Tube (36) until the cables feel tighter. Tighten the Plain Nut to prevent the bolt from turning.

Note: For clarity, the drawing shows the shrouds removed. It is not necessary to remove the shrouds.

Additional slack can be removed by moving the indicated 4Ó Pulleys (35) to different holes in the Pulley Plates (31). To do this, remove the 3/8Ó x 1 3/4Ó Bolt (60), the Cable Trap (44), and the 3/8Ó Nylon Jamnut (63) from the lower Pulley. Move the Pulley to a higher hole and re- attach it with the Bolt, Cable Trap, and Nylon Jamnut.

Make sure that the Low Cable (72) is in the groove of the Pulley and that the Cable Trap is turned as shown. The upper pulley can be adjusted in the same way.

Slack can also be removed by moving the indicated 4Ó Pulley (35) to a different hole in the Pulley Bracket (91). To do this, remove the 3/8Ó x 1 3/4Ó Bolt (60), the Cable Trap (44), and the 3/8Ó Nylon Jamnut (63) from the Pulley. Move the Pulley to the lower hole and re-attach it with the Bolt, Cable Trap, and Nylon Jamnut. Make sure that the High Cable (73) is in the groove of the Pulley and that the Cable Trap is turned as shown.

Note: If a cable tends to slip off the pulleys, the cable may have become twisted. Remove the cable and re-install it.

If a cable needs to be replaced, refer to the back cover of this manual.
