cartridge valve, ﬁttings and plugs.

4 Clean all parts with cleaning solvent.

6 For reassembly, reverse the above procedures except

as follows:

• The cartridge valve back-up rings and O-rings must

be installed as shown to avoid seal damage during

reassembly.

• Lubricate cartridges and seals with petroleum jelly

prior to reassembly.

5.6-5 Eliminating the Arm Opening

Regenerative Function

The 25D, 35D, 40D and 50D attachments utilize a

regenerative hydraulic circuit in the arm opening mode.

The arms open at a faster speed than when closing. The

regenerative circuit can be eliminated (use Service Kit

212867) to give equal arm speed when opening and

closing the arms as follows:

1 Open the attachment arms to the width of the frame.

2 Remove the hose from the check valve port marked CL.

3 Remove the special ﬁtting from the CL port.

NOTE: The spool must remain in the CL port.

4 Install the spring and spacer supplied with the kit into

the CL port, as shown.

5 Reinstall the special ﬁtting and hose.

NOTE: Operate the attachment through several cycles to

remove trapped air in the system and to check for proper

operation. Check for leaks.
