General Maintenance
The proximity switch light should turn on when the target is detected; if not, repeat the adjustment
procedure.
Adjusting Packer Extend Proximity Switch
Packer proximity switches were adjusted at the factory for optimal packer operation. If the area
behind the packer is not properly cleaned daily, proximity switches may no longer stop the packer,
creating a knocking noise when the packer reaches the end of a stroke (bottoming out). The packer
may also not retract far enough to trigger the proximity switch, preventing automatic cycles from
working properly.
Furthermore, over time, misalignment of the components may occur due to the frequent back and
forth motion of the packer. An adjustment might be necessary to prevent cylinders from completely
extending and retracting to the end of their strokes.
Two proximity switches control the packer range of motion. The proximity switch that stops the
packer during extension (packer extend) is located on the front right-hand side corner of the body
next to the left of the packer retract proximity switch (see Figure 3 - 296).

To verify that the switch needs adjusting, empty all refuse from the body, start a pack cycle and
observe the fully extended position of the packer.
Danger!
Always lock out and tag out the vehicle during inspection and maintenance (see

Out and Tagging Out the Vehicle on page 14).
