Trailer Towing Checklist - Air Burners T-400 Operating Manual

T-400 TRAILER TOWING CHECKLIST
Prior to towing a T-400, the following items should be checked and considered:
1. A suitable hitch assembly for the weight of the
T-400 (Gross weight: 6,900 lbs., tongue weight:
1,200 lbs.) is required. The ball size is 2 5/16
inch. To use the pintle hitch, remove the ball
hitch adapter plate fasted by three bolts.
2. The trailer is equipped with electric brakes on
both axles. A suitable brake controller on the
towing vehicle, such as a NAPA P/N 89241 or
a Tekonsha P/N 9055, must be installed. The
proper electrical connector ("pigtail") must be
used to electrically connect the towing vehicle
to the trailer, in order for the brakes (and lights)
to operate properly.
The T-400 has been fitted with a 7-blade RV
type plug and a pig tail that is permanently at-
tached to the T-400 tongue (see trailer-side pin diagram of the 7-pole receptacle on Page
34 "Trailer Wiring Diagram").
IMPORTANT: Ensure that the retracted carrier-pipe/manifold assembly is se-
cured with an appropriate locking device at the front end near the hitch to pre-
vent it from sliding out of the back of the trailer while traveling. Also, make
sure that the cowling latches are secure and the center "D" lift latch (handle)
is locked in place with the provided key. Check all tires, wheel lug nuts, hitch
assembly and safety chains.
3. The trailer tires are 8-ply bias tires, size 225/75D15
(originally supplied). The tires should be inflated to a
(cold) pressure of 65 PSI.
4. Ensure that all lights are working properly.
5. Ensure that all machine components, such as the carrier-
pipe/manifold assembly and cowling are properly se-
cured.
6. Ensure that trailer safely chains are connected to the tow-
ing vehicle and that enough slack is allowed for turning.
7. Ensure the trailer hitch pin is locked with a spring clip or
lock to prevent it from coming loose while traveling.
8. Periodic maintenance is required on the trailer axle bearings. Check with your dealer or the
factory for maintenance schedule. All wheel lug nuts and safety chains should also be
checked before each trip.
