Tower Pulley Adjustment
Tools required: 5/16" hex key, 9/16" open-end wrench
1. Lift the top weight off the
weight stack and insert the
weight pin into the next
weight and the sixth hole
from the top of the weight
rod.
2. Loosen the locknut attach-
ing the pulley to the brack-
et in the top of the tower.
3. Move the pulley to the appropriate location in the
bracket. If more slack is needed in the cable,
move the pulley down. If less slack is needed in
the cable, move the pulley up.
4. Make sure that the cable guard is properly orient-
ed (see CABLE GUARDS on page 8) and retight-
en the locknut attaching the pulley to the bracket.
5. Lift the top weight and remove the weight pin.
Lower the top weight onto the next weight.
6. Readjust as necessary.
7. Slowly perform a repetition using a light load and
have someone make sure that the cable is not
derailed from a pulley or rubbing on a cable
guard.
Top Weight Adjustment
Tools required: 5/32" hex key
1. If the cable needs to be shortened 3/4 in. (2 cm)
or more, follow the instructions in steps 1 and 2 at
the left; then, go to step 2 below.
2. Lift the coupler cover from the top weight coupler.
Loosen but do not remove the two set screws in
each side of the top weight coupler.
3. Pull the cable out of the top weight coupler.
Determine the amount that the cable needs to be
shortened, and cut that much off the end of the
cable.
The cable must be long enough to be
held by the set screws without lifting the top
weight.
4. Cut the cable to the desired length and strip 1 in.
(2.5 cm) of the vinyl sheath from the cut end of
the cable.
5. Insert the cable into the top weight coupler until all
four set screws can be tightened against the
cable. Tighten each set screw alternately 1/4 turn,
until all are set to 85 inch/pounds (9.6 Newton-
meters).
6. Lower the coupler cover over the top weight cou-
pler.
7. Slowly perform a repetition using a light load and
have someone make sure that the cable is not
derailed from a pulley or rubbing on a cable
guard.
