Do not work beneath the unit unless
adequate measures have been taken to
assure the deck will not lower
5) Remove and replace cam roller c/w new
bearings.
6) Remove blocking in the reverse order of
installing same, as described in
paragraphs 3 and 4, and lower the
maintenance strut.
7) Remove vice-grip clamp from release

return to its normal locked position.
8) Walk the deck down to a position
approximately 6" above dock height.
Enter the apron area and lower the lip
by lifting approximately 2", to release the
lip lock, and lowering to hanging
position. See Figure 47.
The lip is heavy, handle with care and
be alert to pinch points.
9) Walk the deck down to its stored
position. At this time, test operate the
unit. The main spring tension may have
been increased to compensate for the
worn or broken cam roller. If the deck is
too hard to walk down and the lip
extends with excessive force, reduce
the main spring tension, equal
counterclockwise turns on each of the
four adjusting nuts, until satisfactory
operation is achieved.
