Disassembly
2.
For Spring-return actuators, do the following:
a.
Tip:
For actuators with assembly code CW, turn back the right hand limit
stop screw (17) 2 full turns.
For actuators with assembly code CC, turn back the left hand limit stop
screw (17) 2 full turns.
This will lower the spring force on the end cap and reduces the screw out
length of the end cap screws.
b.
Important:
Apply a strong, sudden rotational and downward force to
loosen all the end cap screws (10) for maximum 1/4 turn.
c.
Uniformly loosen the screws (10) of the end caps (2) 1/4-1/2 turns at a
time, in sequence, as per figure 18, to relieve the pre-load of the springs.
d.
Remove the o-rings (14) and "B" port seals (16). Discard these parts.
