Travel Adjustment
The following instructions are for fail clockwise (Left-Hand) orientated actuators.
For non-standard models, clockwise and counterclockwise motion will be the inverse of
what is described below. Check the actuator model and orientation before adjusting the
Travel Stops.

Set Clockwise Rotation (Travel Stops A)
1.
Relieve all pressure from the actuator.
2.
Loosen the Travel Stop nuts on Travel Stops A-1 and A-2. Be careful not to
misplace the travel stop O-rings.
3.
Ensure actuator lockout (if provided) is disengaged.
4.
Apply pressure to P1 and P2 to force the pistons fully inward, and away from the
end cap travel stops.
5.
Unthread Travel Stop A-2 four to five full turns.*
6.
Adjust Travel Stop A-1 until travel is set to the desired position. It will be
necessary to relieve pressure from P1 and P2 between adjustments to
determine final position of travel.
7.
Relieve pressure to P1 and P2 and thread Travel Stop A-2 in until it is in firm
contact with the piston.
8.
With pressure relieved, tighten both travel stop nuts on Travel Stops A until they
are in contact with the end cap, then tighten an additional 1/4 turn.
*Clockwise rotation of the travel stops will shorten actuator stroke, counter
clockwise rotation will lengthen actuator stroke�
