NOTE: To extend (or retract) the packer over a short distance, push the green (or yellow) button and
then push the red button immediately. Repeat the process until the packer has reached the
desired position.
NOTE: To reactivate the hydraulic system after the red button is pushed, you have to pull this button
back up then turn ON the pump switch on the in-cab control panel (see Figure 2-5).
9. Turn OFF the hydraulic pump and the engine.
10. Lock out and tag out the vehicle (see Locking Out and Tagging Out the Vehicle on page 12).
Replacing and Adjusting Upper Wear Pads
Follow this procedure to replace and adjust the upper wear pads:
1. Remove and replace both wear pads (see Figure 3-52 and Figure 3-53).
NOTE: Wear pads are not bolted or screwed to the packer. They are simply placed on each end of the
packer, with the 2 protruding guides inserted into the holes provided.
Danger!
Do not enter the hopper while the packer is moving.
