Attach movement arms
Figure 3
1. Slide one swivel arm into each sleeve on the movement arms.
2. Near the bottom of the swivel arms are 90-degree slots that limit the rotation of the thigh
pads. Secure the swivel arms into position on the movement arms using:
2 – M8 x 10 mm screws
3. Slide a retaining ring over the bottom end of each thigh arm that protrudes past the bottom
of the sleeve on the movement arm. Tighten the two ¼-inch set screws on each retaining ring to
fix it in place and prevent the thigh arm from pulling out of the sleeve on the movement arm.
Note: Verify that the retaining ring fits loosely against the swivel arm, then tighten the set
screws. The swivel arms should be able to rotate freely. If the retaining ring is too tight against
the swivel arm, then rotation of the swivel arm will be too stiff.
Install weight stack tower
Figure 4
1. Insert the guide rods into the holes at the bottom of the weight tower frame.
Important: A hole passes through one end of each guide rod. Be sure to insert the end
without the hole into the bottom of the frame.
2. Pull the guide rods away from the frame, keeping their lower ends engaged in the bottom of
the frame. Slide one weight stack bumper over each guide rod, narrow end up.
3. Check the guide rods for silicone lubricant. If you do not find any, add some of the lubricant
supplied in the hardware kit to the guide rods.
4. Carefully slide sixteen 10 lb. (4.5 kg) weight plates onto the guide rods, one by one.
5. Slide the top weight plate with weight stack stem onto the two guide rods and lower the
stem through the center holes of the weight plates.
6. If the cable assembly is attached to the top weight plate, then unscrew it and remove it at
this time. Slide the ring at the end of the tether of the weight selection pin over the right-hand
post on the top weight plate.
7. Secure the weight stack assembly to the weight tower frame. Slide an O-ring onto the smaller
diameter shoulder of each guide rod locking collar, then slide the collars onto the guide rods
(the smaller diameter shoulder on the collar should be facing up). Re-align the guide rods with
the mounting holes at the top of the weight tower.
8. Have your assistant hold the guide rods in place. Slide the collars up until the shoulder of
each collar fits into the tower frame. Insert one M6 × 45 mm button head cap screw through
the holes in each collar and each guide rod, then attach an M6 nylon lock nut to each button
head cap screw. Tighten the button head cap screws securely, then attach and tighten the M8
set screws using the S4 hex key.
9. Spray a lint-free cloth with isopropyl alcohol and wipe the front of the weight plates clean.
Use a second lint-free cloth to remove any remaining alcohol before applying labels.
10. Apply the weight plate labels (select LBs or KGs) to the left of the weight selection holes.
