Pull Test; Unhitching Procedure - Horizon Global PRO Serie Manuel D'instructions

PULL TEST

Failure to perform this test may result in death or serious injury!
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
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!
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.

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.
Trailers that are not stable or properly hitched can fall and kill you! To avoid
death or serious injury:
4. Lower truck tail gate.
5. Disconnect power cable and breakaway switch cable between truck and trailer.
6. Remove lock from handle tab and sleeve.
7. Make sure that there is no rearward load on the king pin locking bar. If this is the case, the handle and king pin locking bar
will be difficult to open. DO NOT FORCE HANDLE. Back truck into trailer and reset truck emergency brakes.
8. Pull handle out (A) and forward (B) so that the groove in the handle catches the side of the hitch head and cocks it open
(C). See Figures 16 and 17.
