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
touch the limit switch preventing the
automatic cycle to work properly.
After a certain period of time, a
misalignment of the components may
occur due to the frequent back and
forth movement of the packer. An
adjustment might be necessary to
prevent the cylinders from completely
extending and retracting to the end of
their strokes.
Two limit switches control the
extension and retraction limits of the
packer (before the end of cylinder’s
stroke):
• the packer extension limit switch
stops the packer during its
extension;
• the packer retraction limit switch
stops the packer during its
retraction.
Both limit switches are located at the
front end of the body, on its right-hand
side, between the cab and the body
(Figure 66. “Packer cylinder limit
switches” ).
