* Clockwise rotation of the travel stop will shorten actuator stroke (stroke < 90°),
counterclockwise rotation will lengthen actuator stroke (stroke > 90°).
# These travel stops were installed with thread locker and may require an application of
heat before they may be adjusted. It is recommended the user reapply thread locker after
their adjustment.

Installation, Operation and Maintenance Manual
Relieve all pressure from the actuator.
Ensure actuator lockout (if provided) is disengaged.*
a.
Loosen the travel stop nut on Travel Stop B. Be careful not to misplace
the travel stop O-ring.
b.
Adjust Travel Stop B until the stroke is set to the desired position. It may be
necessary to stroke the actuator in the counterclockwise direction between
each adjustment. This can be accomplished by applying pressure to P1.
c.
With pressure applied to P1, tighten the travel stop nut until it comes in
contact with the body.
If counterclockwise travel adjustment on a dual cylinder actuator is required in the
field, it is recommended the user accomplish this via bracket motion followed
by resetting Travel Stops A via the directions listed above. If this cannot be
accomplished, follow the steps below.
a.
Follow Section 4.4, Steps 1 to 3.
b.
Adjust each Travel Stop B the appropriate amount. Use the table below as a
guide as travel cannot be checked without fully assembling the actuator.
