mating grooves in the weight stack frame (1).
Slide the lower rear shroud (19) into the
mating grooves in the weight stack frame.
Install one tapped hole nut (68) onto each of
the six upper shroud mounting tabs on the
weight stack frame (1).
Hold one upper shroud (20) in position
against the weight stack frame (1), and
secure the shroud to the frame using three
screws (63) and washers (72).
Repeat for the remaining upper shroud (20).
8. Final Assembly and Testing
Check all attaching parts to ensure they are
tightened securely.
Verify operation of the seat post:

Mount the unit. While holding the seat post,
press the ratchet handle to retract the locking
pin, and raise the seat. Release the ratchet
handle, and verify the locking pin engages the
first drilled hole at the first seat position.

Repeat to verify the locking pin engages
the drilled hole at all seat positions.

Return the seat post to the "stowed" position.

Verify the seat post slides smoothly,
without evidence of sticking or binding.
Verify operation of the leverage arm:

Pull out on the leverage arm pull pin to
retract the locking pin, and hold in the
retracted position. Rotate the leverage
arm upward, then release the locking pin.
Verify the locking pin engages a drilled
hole in the flywheel ratchet.

Repeat to verify the locking pin engages the drilled hole at all leverage positions.

Return the leverage arm to the first position.
Mount the unit. Engage the selector pin at a comfortable weight. Adjust the seat post and leverage arm as desired.
Operate the leverage arm and check the following:

Verify operation of the leverage arm is smooth, without evidence of sticking or binding.

Verify there is no evidence of "free play" when actuating the leverage arm from the "stowed" position.

Verify there is no evidence of excessive noise during operation.
Return the leverage arm to the "stowed" position.
