WEIGHT STACK SERVICING
Servicing the weight stack involves replacing the bush-
ings in the weight carriage. To order these parts, see
HOW TO CONTACT CUSTOMER CARE on the back
cover of this manual.
1. Lift the cap off the tower. Next, remove the access
cover by pulling it free at the bottom and then slid-
ing it upward until the tabs release.
2. Remove the nuts and washers from the upper
ends of the weight guides, and let the weight
guides slide down to the floor.
3. Slide the weight carriage upward off the upper
ends of the weight guides. Note: Pull the weight
guides toward the back of the strength equipment
for increased clearance.
4. Unscrew and remove the two existing weight guide
bushings from the weight carriage. Discard the
weight guide bushings.
5. Tighten two new weight guide bushings into the
weight carriage.
Do not overtighten the weight
guide bushings. If they are overtightened, they
may make a chattering noise when they move
on the weight guides.
6. Clean and lubricate the weight guides by wiping
them with a soft cloth containing 10W-40 or 10W-
30 lightweight motor oil. Apply only a light coating
over the entire length.
Do not use -based lubri-
cants.
7. Replace the weight carriage on the weight guides.
8. Reattach the weight guides to the top of the tower.
9. Insert the weight pin into the weight carriage. Pull
the foot strap, lifting the weight carriage all the way
to the top. Slowly return the foot strap to the rest-
ing position.
If the weight carriage sticks, loosen the nuts on
the upper end of one of the weight guides. Lift the
weight carriage to the top again. Retighten the
nuts. Check the full travel again and readjust the
weight guides as necessary.
10. Slowly perform a repetition and have someone
make sure that the cables are not derailed from a
pulley or rubbing against a cable trap.
11. Reattach the access cover and the cap.
