Problem with air operated steeps on fc birds

[Tom Warner]

Jon if you look under the back of the step you will find either one
or two microswitches that control the shut off of air to the step
when it is fully out or fully in. Yours might have only one
microswitch and only god knows why BB designed some of the BB with
only one (like mine). You will also find 2 air solenoids one to
control air to push the step out and one to pull it in. They are
connected to a double acting air cylinder (one to each end thru a
1/4" plastic air line. On the back of each air solenoid you will
find a small round brass sintered filter with a screw thru it that
can be adjusted with a screwdriver. This adjustment determines the
speed which the air step goes out and in.
There is also a switch on the small panel to the left of the entrance
as you go in the coach that allows you to hold the step out even if
the door is opened and closed and throwing the switch in the other
position the steps will act normally, out when the door is opened and
in when the door is closed.
