Treadwall® Service Bulletin #22 - Adjustment of resistance lever.
When the resistance lever is in the middle of its range, the wall should drop at about one
panel per second with a 160 lb. climber. The diagram shows the approximate positions of the
valve lever and the resistance lever for the
maximum resistance setting. At this setting the
wall will be locked up and not move. When the
machine is first set up, use the turnbuckle to
adjust the levers to look like the diagram, then
fine tune to give the proper speed of descent at
the middle position.
When servicing the turnbuckle, be very careful
not to
drop
anything
down the
front leg
of the
frame.
After
adjustme
nt, be
sure to
lock the
turnbuckl
e with
the
locknut.
This
locknut
is a
left-hand
thread.
