3. Release the lock pin and make sure the pin fully en-
gages the attached tongue bracket.
Be sure dirt, sand, ice, etc., does not obstruct
the proper seating of the lock pin.
4. When raising or lowering the jack, prevent the caster
from rotating while cranking. Make sure the jack is
planted on a firm and level surface before unhitching
the trailer.
To prevent personal injury or damage to the boat
and trailer, observe the following:
• NEVER pull on the lock pin when any trailer
weight is on the trailer jack.
• DO NOT move the trailer when resting on
the swivel jack. Use towing vehicle to move
the boat and trailer.
• Keep body and feet clear of trailer tongue
when raising or lowering jack.
Alway remember to swivel jack to the horizontal position
before towing the trailer. Damage to the caster and jack
may result.
The swivel jack provided on the Four Winns® trailer can
be removed from the trailer to allow for maintenance or
repairs. Follow the manufacturer’s recommendations
provided in the owner’s packet.

E. Surge Disc Brakes
Surge disc brakes are available on 2000 model trailers
manufactured by Four Winns®. Surge disc brakes op-
erate automatically when the tow vehicle’s brakes are
applied. When the tow vehicle slows down or stops, the
forward momentum or “surge” of the trailer against the
hitch ball applies pressure to a master cylinder in the
trailer coupler. The master cylinder supplies hydraulic
pressure through the hydraulic system which activates
the trailer’s disc brakes. See Figures S5 and S6. Please
refer to the manufacturer’s literature included in your
owner’s packet for further details regarding operation
and maintenance.
The benefits of disc brakes in comparison to drum
brakes:
• Fewer moving parts.
• Longer life due to fewer moving parts.
• Friction pads are easily accessible.
• Easy access to caliper for cleaning and
maintenance.
• Calipers are self-adjusting allowing smoother
braking operation.
• Braking performance less likely to be
affected by dirt, water, or rust contamination.
• Fade resistant.
