CHAPTER 3 Setup and Test
3.4.2
The shackle on the tow cable connects mechanically to the towfish K-Wing
depressor tow bracket using a tow pin. The depressor connects mechanically to the
towfish.
To connect the tow cable with the optional depressor:
Remove the retaining ring from the beveled end of the tow pin, withdraw the
1.
pin from the tow bracket and set it aside. Remove the two bolts and tow
brackets from the welded-on six-hole towing flange. Take note of the location
of the tow brackets for future reference.
2. Position the K-Wing depressor over the towing flange in the same location as
where the tow brackets were previously connected. Secure the depressor to the
towing flange with the fasteners provided.
3. Align the tow shackle mounting hole with the mounting hole of the K-Wing
depressor tow bracket, with the shackle pigtail connector facing the tail of the
towfish. Insert the beveled end of the tow pin through the holes in the tow cable
shackle and the bracket, and secure the tow pin with the retaining ring.
4. If the towfish was previously configured for towing without a depressor, extend
the free length of the tow cable jumper to reach the shackle pigtail connector. Do
not extend more than is needed to make the connection and to provide free
rotation of the tow shackle.
5. Remove the dummy plug from the connector on the end of the tow cable jumper.
6. Apply a thin film of silicone grease to the pins of the connector. Do not over
grease.
7. Connect the tow cable to the tow cable jumper by aligning the male and female
connectors and pressing them firmly together. If necessary, use a slight side to
side rocking motion while pressing on the connector, but do not bend the pins.
When properly inserted there should be no gap between the surfaces of the two
connectors.
8. Secure the tow cable jumper with cable ties to the top of the towfish.
