Adjusting Packer Retract Proximity Switch
The packer retract proximity switch (see Figure 3 - 299), which is one of the two proximity switches
that control the packer range of motion (the other being the packer extend proximity switch), is
located on the front right-hand side corner of the body. This proximity switch allows lowering of the
crusher panel (if equipped) when the packer is in the home position and stops the packer during
retraction (packer retract).
Figure 3 - 299 Packer retract proximity switch
To verify that the switch needs adjusting, empty all refuse from the body, start a pack cycle and
observe the home position of the packer when it completes its cycle.
If the packer stops before reaching the home position or if the packer cylinders remain pressured up
or abruptly bottom out while the packer is at the home position, adjust the switch as follows.
To adjust the packer retract proximity switch:
1. Start the engine and engage the hydraulic pump.
Danger!
Always lock out and tag out the vehicle during inspection and maintenance (see Locking
Out and Tagging Out the Vehicle on page 14).
Important
