1. With:
• All trailer wheels still firmly blocked, and
• Trailer land gear still resting on firm ground and supporting trailer weight and,
• Truck stationary and with emergency brake on:
Return to cab of truck and release truck’s emergency brake. Apply trailer brakes. After making sure no one is between
truck and trailer, try to pull trailer slowly forward with the truck. If the trailer is properly hitched, the wheel blocks and trailer
brakes should keep the truck from moving forward.
NOTE: If trailer is not properly hitched, trailer will separate from hitch and truck will move forward leaving trailer behind. If
the trailer landing gear is still on resting on firm ground supporting trailer weight and wheels are blocked, trailer will
not be able to drop or fall
2. After successfully performing above steps, fully raise trailer landing gear (see trailer manual).
3. Check and inspect all electrical circuits for proper operation. (Clearance lights, turn signals, stop lights, etc.).
4. Remove and store all trailer wheel blocks.
PERFORM THE FOLLOWING IN THIS ORDER:
1. Place blocks firmly against front and rear of each trailer wheel to prevent any possible forward or rearward motion.
2. Using trailer jacks, lower trailer landing gear following the directions in the Trailer Manual until feet of landing gear are
resting on firm ground.
3. Make sure truck is in park with the emergency brake on.
UNHITCHING PROCEDURE:
PULL TEST
WARNING:
Trailers that are not stable or properly hitched can fall and kill you! To avoid death
or serious injury:
•
All trailer tires MUST be blocked in front and behind each tire AND
•
Trailer landing gear MUST be resting on firm ground AND
•
Truck MUST be stationary, in park, with emergency brake on!
WARNING:
Failure to keep wheels blocked and landing gear down could result in trailer suddenly
moving or falling. This could result in death or serious injury!
WARNING:
Failure to perform test may result in death or serious injury!
4. If necessary, lower truck tail gate.
5. Disconnect power cable and breakaway switch cable between truck and trailer.
6. Rotate latch for hitch handle toward trailer and free of groove in handle. (Fig. 17 on next page)
7. Pull hitch handle out completely until it latches in open position so that king pin is no longer
securely grasped by hitch jaws (See Fig. 18 on next page). Trailer is now free from hitch and
truck. If handle does not pull out, there is probably pressure against the jaws. To relieve this
pressure, back the truck slightly. Reset truck emergency brake. Then pull hitch handle out
completely until it latches in open position. (See Fig. 18)
