Locking Pin Release
To prevent personal injury or damage to the
boat and trailer, observe the follow ing:
NEVER pull on the lock pin when any
trail er weight is on the trailer jack.
DO NOT move the trail er when rest ing on
the sw iv el jack. Use tow ing vehi cle to move
the boat and trail er.
Keep body and feet clear of trailer tongue
when raising or lowering jack.
Always remember to swivel jack to the horizontal posi-
tion before towing the trailer. Damage to the caster
and jack may result.
The swivel jack provided on the certain Scarab trailer
can be removed from the trailer to allow for main te-
nance or repairs. Follow the man ufac turer's rec om-
mendations provided in the owner's packet.
D. Surge Brakes & Coupling Assembly
Surge brakes are available on certain Scarab trailers.
When equipped, surge brakes operate auto mati cally
when the tow vehi cle's brakes are ap plied. When the
tow vehicle slows down or stops, the forward mo-
mentum or "surge" of the trailer against the hitch ball
applies pressure to a master cylinder in the trailer
coupler. The master cylinder supplies hydraulic pres-
sure through the hydraulic system which activates
the trailer's disc brakes. See Figure F5. Please
refer to the manufacturer's literature included in your
owner's packet for further details regarding operation
and maintenance.
To hitch the trailer to the tow vehicle, place the cou-
pler latch in the open position to unlock the coupler.
See Figure F5. Push down on the coupler latch to
lock the trailer to the ball hitch. Push coupler latch
lever back until the latch engages and is properly
seated. The safety pin, provided with the trailer,
or a padlock must be inserted completely in the
forward coupler latch hole. See Figure F6. This helps
ensure the coupler's latch remains in the locked
position during towing of the trailer. Refer to Section
F-3 Operation for addi tional information on couplers
and hitching to the tow vehicle.
