With the electronics compartment positioned outside the edge of
the vise clamps, clamp the seatpost head into a bench vise with flat
aluminum soft jaw vise inserts on the flat saddle clamp slots.
NOTICE
To avoid permanent damage to the electronic components, clamp
only the flat surfaces
of the circular saddle clamp slot in the seatpost
head.
Insert a 1.5 mm hex wrench into one of the cross holes in the IFP tube.
Carefully pull the IFP tube up. Use your other hand to guide the IFP
tube straight out of the upper post using care not to scratch the inside
of the upper post with the hex wrench.
Wipe the outer surface of the IFP tube and set it aside on a clean shop
towel.
NOTICE
Do not scratch the inner surface of the upper post, or the IFP tube.
Surface scratches can cause leaks and reduce performance.
If the IFP tube is scratched, it must be replaced.
