Trouble-Shooting And Maintenance

Make sure all parts are properly tightened each time you use the weight system. Replace any worn parts immedi-
ately. The weight 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 weight 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, insert the Weight Pin (39) under
the third Weight (26) from the top. Next, loosen the 1/2"
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 shroud
removed; it is not necessary to remove the shroud.
Additional slack can be removed by moving the indicated
4" Pulleys (35) to different holes in the Pulley Plates (31).
To do this, remove the 3/8" x 1 3/4" Bolt (60), the Cable
Trap (44), and the 3/8" 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 4"
Pulley (35) to the lower hole in the Pulley Bracket (91).
To do this, remove the 3/8" x 1 3/4" Bolt (60), the Cable
Trap (44), and the 3/8" 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.
