2. Push the yellow button to retract the packer up to 1 inch from the fully retracted position
(see Figure 3-300).

3. When the packer reaches the correct position, push the red emergency STOP button.
4. Locate the packer retract proximity switch on the front right-hand side corner of the body (see
Figure 3-299).
5. Loosen both bolts (see Figure 3-301) and adjust the proximity switch so that it gets triggered (its
amber light turning on).
Triggering occurs when the plate (target) is detected by the switch.
6. Retighten the bolts.
7. Engage the hydraulic pump and check for proper operation.
Make sure that the proximity switch detects the plate properly.
Ideally, there should be a gap of approximately 3/16 inch between the proximity switch and the plate.
If this is not the case, apply the following procedure:
To adjust the gap between the proximity switch and the plate:
1. On the proximity switch, loosen the nuts located on each side of the proximity switch bracket
(Figure 3-301).
2. Push or pull the proximity switch until there is a gap of 3/16 inch between the plate and the
switch.
3. Tighten up both nuts.
4. Make sure that the proximity switch detects the plate properly.
5. Test the packer for a full cycle.
Danger!
Do not enter the hopper while the packer is moving.
