LIP ACTUATOR REPLACEMENT – Cont’d
12) Remove the 2" x 4" blocks that are
holding the lip up, and allow the lip to
lower until its weight is supported by
the lip lock. See Figure 34.
The lip is heavy, handle with care and
be alert to pinch points.
13) Inspect all work performed to assure
retainers are in place, etc. and
lubricate the entire unit.

14) Pull the hold down release ring up firmly and hold in released position for a moment,
to allow the main lift springs to lift the deck slightly and support the weight of the
deck.
15) Ensure the maintenance strut is in the raised position. Remove the deck support
blocking. Lower the maintenance strut.
16) Grasp the leading edge of the lip and pull the deck down to approximately 6" above
dock height. Lift the tip of the lip approximately 2" to release the lip lock and then
lower to its hanging position. See Figure 43.
The lip is heavy, handle with care and be alert to pinch points.
17) Walk the deck down to stored position.
At this time, the main spring tension
may have been increased to
compensate for damaged shock, etc.
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.
18) If further adjustment is required, see
the 'Trouble Shooting Section of this
manual, Group 04, Section 01, Pages
1 and 2.
