Installing the Weight Arm
When the equipment is completely assembled, the weight arm supports the
weight plates that are loaded onto the equipment. A belt connects the weight
arm to the cam on the movement arm.
To install the weight arm:
1. Remove the plastic ties that hold the spacer rings in place in the weight
arm pivot bracket.
2. Position the pivot end of the weight arm over the bracket.
3. Slide the end of the weight arm into the bracket so that the openings in the
bracket and the movement arm are aligned.
4. Press the weight arm axle through the openings in the bracket and the
weight arm.
Note: The axle should slide easily through the openings. You should not
need to do anything more than tapping it lightly with a rubber mallet to
move it into place. If the axle becomes jammed during this step, check to
make sure the movement arm and the bracket are still aligned. If the axle
remains jammed, remove it and contact Customer Support.
5. Place an axle mount end on each end of the axle and attach a M12 x 30
mm flat head screw to each end, as shown in the following figure.

Important: Test the operation of the weight arm after you have installed it. Make
sure it moves smoothly through its entire range, without binding or shifting.
6. Verify that the frame is properly aligned, then tighten all frame fasteners
completely.
