Spring Module Removal

WARNING: CHECK SPRING CARTRIDGE POSITION
The spring cartridge must be checked to verify that the spring(s) are in their extended posi-
tion before the spring cartridge is removed from the actuator.
NOTE:
When the spring module is to be removed it should be removed from the drive module
prior to the hydraulic power module removal or disassembly.
Review Section 2.1 General Disassembly before proceeding with spring module disassembly.
The setting of stop screws (1-180) should be checked and setting recorded before stop
screws are loosened or removed.
