8. Selection of the row of holes depends on the width of the actuator
yoke. The roll (5) should engage in the pick--up bracket (2) as
close as possible to the spindle but may not touch the clamping
assembly.
9. Hold the positioner with the mounting bracket on the actuator so
that the pin (4) is guided within the pick--up bracket (2).
10. Tighten the pick--up bracket.
11. Position the mounting parts according to the type of actuator.
-- Actuator with ledge: Hexagon head screw (8), flat washer (11)
and lock washer (10).
-- Actuator with plane surface: Four hexagon head screws (8), flat
washer (11) and lock washer (10).
-- Actuator with columns: Two U bolts (7), four hexagon nuts (21)
with flat washer (11) and lock washer (10).
12. Secure positioner onto the yoke using the previously positioned
mounting parts.
NOTE
Set the height of the positioner so that the horizontal lever position is
reached as close to the stroke center as possible. You can use the
lever scale as orientation. If no symmetrical mounting is possible it
must be guaranteed that the horizontal lever position is passed
through within the stroke range.
