:
Full Eject : The actuator bolt is attached to a clamp that should be 1/16 in. (1.58 mm) below the
top of the shaftend 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.

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.

Continue with the adjustment of the half pack proximity switch, if necessary, or replace cover.
Adjusting Half Pack Proximity Switch
The half pack proximity switch controls the sweep of the packer blade. An actuator trips the half pack
proximity switch when the packer blade reaches the half pack position during an Auto-Pack or pack
operation.
Location:
The half pack proximity switch is positioned on top of the front header (front of the body) on the
curb side.
