3.0 Upgrade Steps
3.1 Mount the resistance unit
1. Confirm that the 2 set
screws protrude slightly from
the load cell. If they do not,
insert the 3mm Allen Key into
the screw hole from the rear
side through the plastic
shield, and turn the screws to
the right until they protrude
by at least 2 threads.
2. Unscrew the two mounting
bolts on your STAC Zero
resistance unit using your
4mm Allen Key, and remove
the resistance unit.
3. Use the position of your old
resistance unit as your initial
guide for mounting the new
resistance unit. Attach your
Fliiiight resistance unit to the
frame, tightening the 2
mounting bolts enough to
prevent any movement of the
resistance unit until you
perform the alignment steps.
