off and remove the key (see
Lockout/Tagout Procedure on page 37).

:
Full Eject : The actuator bolt is attached to a clamp that should be 1/16 in. (1.58 mm) below the
top of the shaft-end cylinder collar.
Tip-to-Dump : The actuator bolt is threaded into a plate that is welded to the cylinder tube.
The actuator bolt is cemented in place with Locktite 242 or 272.
3.
Check the gap between the proximity switch and the tab.
If the gap is too wide or too narrow, proceed with the adjustment:
3 a. Loosen the proximity switch mounting nuts. Slide the switch forward or backward in the
mount to achieve a gap of approximately 1/4” with the tab.
3 b.
Tighten the proximity switch nuts.
3 c.
Test the operation.
4.
Start the Front Loader, switch ON the hydraulic pump and test the packer blade operation.
5.
Repeat steps until the half pack proximity switch is correctly adjusted.
6.
Reinstall the cover protecting the packer blade ahead and half pack proximity switches.
