1. Remove the access cover by pulling it free at the
bottom and then sliding it up until the two sets of
tabs release.
2. Remove the screw on each guide rod and let the
guide rods slide down to the floor.
3. To remove the top weight, first unbolt the “U”-
bracket from the weight rod.
4. Slide the top weight off the top of the guide rods.
Note: Pull the guide rods toward the back of the
machine for increased clearance.
5. Servicing the weight stack involves replacing the
two guide bushings and weight insert in the top
weight. First, use a punch to drive the two exist-
ing guide bushings and weight insert out of the
top weight.
6. To insert the new bushings and weight insert,
hold a bushing square to the face of one of the
holes in the top weight, place a protective piece
of wood on top of the bushing, and lightly tap the
bushing into place. The bushing should be flush
with the surface. Repeat with the other bushing
and weight insert.
7. Replace the top weight on top of the weight
stack.
8. Reattach the “U”-bracket to the top weight cou-
pler.
9. Clean and lubricate the guide rods by wiping
them with a soft cloth containing a light weight
motor oil, 10/40 or straight 30 weight. Apply only
a light coating over the entire length.
Note: Do
not use Teflon or Silicone based lubricants.
10. Reattach the guide rods to the top of the frame
with the two bolts.
11. Insert the weight pin into the top weight. Pull the
handle, lifting the top weight all of the way to the
top. Slowly return the handle to the resting posi-
tion. If the top weight sticks, loosen the screws
on the guide rods. Lift the top weight to the top
again. Retighten the screws. Check the full travel
again and readjust the guide rods if necessary.
12. While slowly pulling the handle, have someone
check the cable guard on the top weight to
ensure that it is not dragging or rubbing on the
cable.
13. Replace the access cover.
