SECTION 2 - TRAILER OPERATION
2-8 – Triple-L-Trailer – 3121224
Automatic Transmission Oil Cooler
The automatic transmission of a towing vehicle handles
more power when a trailer is being towed. Inadequate
cooling will shorten transmission life, and may result in
sudden transmission failure. Ask the tow vehicle dealer if it
is necessary to install a separate oil cooler for the auto-
matic transmission.
Fire Extinguisher
A fire extinguisher should be carried in the tow vehicle.
Emergency Flares and Emergency Triangle
Reflectors
Carry these warning devices when towing a trailer
because the hazard flashers of your towing vehicle will not
operate for as long a period of time when the battery is
running both the trailer lights and tow vehicle lights.
2.9 COUPLING AND UNCOUPLING THE
TRAILER
The trailer must be properly and securely coupled to the
hitch of the tow vehicle.
UNCOUPLING OF THE TRAILER DURING TRANSPORT MAY
RESULT IN DEATH OR SERIOUS INJURY.
Before Coupling the Trailer to the Tow
Vehicle
Be sure the size and rating of hitch ball match the size and
rating of the coupler. Hitch balls and couplers are marked
with their size and rating.
Wipe the hitch ball clean and inspect it visually and by feel
for flat spots, cracks and pits.
BEFORE EACH TOW, INSPECT THE HITCH BALL FOR WEAR,
CORROSION AND CRACKS BEFORE COUPLING TRAILER.
REPLACE WORN OR DAMAGED HITCH BALL.
NOTE: Rock the hitch ball in all directions to make sure it is
tight to the hitch, and visually check that the hitch
ball nut is solid against the lock washer and hitch
frame.
Prepare the Coupler and Hitch
Lubricate the hitch ball and the inside of the coupler with a
thin layer of automotive bearing grease to reduce wear
and ensure proper operation. If your trailer is equipped
with a tongue jack, raise the coupler above the ball height.
BEFORE EACH TOW, BE SURE THE HITCH BALL IS TIGHT TO
THE HITCH BEFORE COUPLING THE TRAILER.
1. Wipe the inside and outside of the coupler clean and
inspect it visually for cracks and deformations; feel
the inside of the coupler for worn spots and pits.
Be sure the coupler is tight to the tongue of the
trailer. All coupler fasteners must be visibly solid
against the trailer frame.
