Before he coupled the trailer he charged the trailer without chocking the trailer tires. A big no-no. Either chock the tires or couple tractor-trailer before charging the brakes on the trailer. Stay safe drivers!!
@@robertolson7304 That trailer the brakes are already locked... connecting the red airline does not unlock the brakes... until you Supply Air to the trailer by pushing the red Air Supply buttons in... it takes air to release the trailer brakes!!!!
Question, should a tug test be done prior to hooking up the air lines so you know the fifth wheel jaws are locked around the kingpin? Or do you attach the air lines and do a tug test in order to check the trailer brakes? Also, it seems like it would be a good idea to chock the wheels of the trailer prior to coupling to make sure the trailer doesn't move. I'm a brand new driver and would really appreciate your feedback.Thanks
You can do a tug test with or without the lines on, if on , just don't charge the system with air. Then get out and look to see if the release handle is all the way in and check to see if the jaws are around the kingpin and locked, then charge the trailer(red) valve and if you have a trolley, pull down on it to check for service side leaks. But, keep the tractor protection valve(yellow) set.
Interesting Video Everything Looked good except Charging the Trailers Brakes before connecting it to the Truck... Although prior to 1970 most Trailer Brakes Needed to be Charged with Air to be On! So, the 'hooking up' demonstrated in this Video would be Correct for the 1960's ! D
This way is still required for the national CDL test...to connect the airlines and charge the brakes first...they have not updated the CDL test since the invention of spring brakes in the 1970s. In 'real life' you do not need to connect the airlines first.
And this was made in what year? I went to a 10 week school in 1991 and we saw videos from the ATA and I don't recall ever seeing this one. Maybe because there are steps that can/should be left out. And I have yet to see a video showing what to do when you are picking up a trailer that was dropped too high or too low by an idiot driver and there isn't anyone around but yourself. That's why I keep a pair of either four by four or six by six blocks of wood in my side box...
why the heck would you CHARGE the trailer before you hook up?? are you crazy.. that releases the trailer brakes.. if those wheels arnt chockd the trailer could roll away.. YET then you apply trailer brakes then hook up!! wierd!! hook up to trailer, tug test, then you can charge trailer!
youtube search "Coupling and Uncoupling Tutorial" by J-TECH.... that's the proper way to do it!!! NEVER EVER EVER, charge trailor if its not hooked up to truck!
The DMV/CDL test is OLD and still says to charge the trailer first. Spring brakes were invented in the 1970s, but the CDL book/test has not been updated since the 1970s. Old trailers without spring brakes are unheard of on the road, they mainly are in a farmer's field as a storage unit.
You are doing it all wrong! -Coupling the trailer: Step one: approach the trailer at any angle Step two: press the coupling key on the keyboard (usually it's "T") Done! -Uncoupling the trailer: Step one: park anywhere you'd like Step two: press the same key as above Done! Believe me. I've played American Truck Simulator.

Merry Christmas 2013. Thanks for your help
Merry Christmas 2017. And so it goes.
When pulling out the red button trailer air supply... that will release all the air of the trailer locking the trailer brakes!
Great content, it assisted with the passing the endorsement exam.
Thank you
thanks for your help good video!!!!
did I miss something at what point did he pretrip the trailer and check the lights
👍🏻

depends on the state.. some states require you to charge the system with or without chocks..

What CDL school did you go to?
Supplying Air to the trailer via the red button pushed in is what releases the brakes!

Thanks, I never thought about coupling the lines but not charging the trailer brakes.

You are correct...but the CDL test still requires this step on the test. They have not updated the CDL test since the 1970s.
Well, now that we've seen how not to couple a tractor and trailer, we'd like to see the video on the correct way.

How do you know were to keep the faith wheel?
Keep the faith wheel well inflated with air. The air pressure should be 85 to 100 PSI. 😀
Thank you!
7:29 for step 10: pull fifth wheel release hatch to open position
If your tractor is not hooked to the Kingpin first... and you Supply Air to the trailer which releasing the brakes the trailer May roll-away!
You should put on the trailer park brake before coupling.
Can you make a video on backing?
Step back and make selfie. 😀
Yeah
step 15 translated: get your stuff out of my truck and stop wasting company time

Now I'm confused, thats what the DMV handbook says to do.
autohog Go by the book

Misinformation... always hook your Kingpin first... before supplying Air to the trailer... air unlocks your trailer brakes!
