1.
With :
•
All trailer wheels still firmly blocked, and
•
Trailer landing gear still resting on firm ground and supporting trailer weight, and
•
Truck stationary and with the 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 resting on firm ground supporting the trailer weight and wheel 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.
PULL TEST
WARNING
:
Failure to perform this test may result in death or serious injury!
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!
UNHITCHING PROCEDURE:
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.
4.
Lower truck tail gate.
5.
Disconnect power cable and breakaway switch cable between truck and trailer.
6.
Rotate hitch handle up to the unlocked position (See Fig 18) and pull the handle towards you so that the king pin is no longer
securely grasped by hitch jaws (See Fig 19 ). 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.
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!
