392 Lifting Arms
8. To adjust the outer rail retraction movement cushioning, open the doghouse door. Tighten the
retraction cushioning adjustment screw (if equipped) to obtain a smoother movement at the end
of the stroke or loosen it if the movement is too slow (no shock shall occur).
9. To adjust the outer rail extension movement cushioning, tighten the extension cushioning
adjustment screw (if equipped) to obtain a smoother movement at the end of the stroke or
loosen it if the movement is too slow (no shock shall occur).
IMPORTANT: Since 2 cylinders are involved in the extension of the HELPING-HAND™ automated arm, make sure to
identify the problematic cylinder before adjusting cushioning.
Auto-Packing
The Auto-Packing switch (see Figure 10-18) enables the packer to automatically start cycling about
2 seconds after the gripper reached the mid-height position on its way up. If the packer is performing
a cycle while the lifting arm carries a rolling cart towards the hopper, the packer will immediately stop
and return to its home position, no matter where it was in the hopper. This is to prevent refuse from
falling directly on the packer. However, there is one exception to this: if, after 3 consecutive packing
cycles, the packer fully extend proximity switch has not been activated, the packer will not return to its
home position.

Auto-Packing switch
When the Auto-Packing feature is used simultaneously with the Multi-Cycle feature, the packer will
then perform a preset number of cycles unless a new rolling cart is carried towards the hopper by the
automated arm. In such a case, the Multi-Cycle feature will then be reset to zero.
When a packing cycle has been interrupted and the packer has returned to its home position, a new
cycle will begin 2 seconds after the gripper reached the mid-height position on its way up.
