How To Uncouple a Trailer:
Step 1 - find a safe and secure and flat area to park
Step 2 - park brake on
Step 3 - legs down
Step 4 - disconnect air line and electrical cable
Step 5 - release the jaws of the turn table
Step 5 - drive away

Thanks for sharing this great video. You are a really good teacher. I have difficulty coupling the trailer. Speifically, backing up straight to allign.
Thanks for the videos. They make revision so easy.
Thanks for sharing, as I am learning the tug(yard dog) to move trailers around in my workyard atm!!!
I'm very thankful for watching this video
Nice driving
Thanks for your Instruction and a good video
Very informative video for learners. Keep it up 👍
Really nice insights, thanks.
Luv ur motorcycle videos aswell!!!
Good video. Thx
It's good job
Thanks for the information. But if some want to be trained and start working is it possible
Thank you
You make stuff very easy for beginners. Iam trying to get a truck licence in NZ. Only class 2. Not the trailor. Want to learn all the basic tricks. Plz make a videos of you going downhill on a truck. How to change gears and brakes.
Happy to help! Will do a video on gears and hill soon! Great suggestion!
Good job bro..
thanks mate
I was always told to use the word HELP. Which is hose electrical leg then pin or to hook up pin then leg electrical hose . Then brake test
Thats the CORRECT way to do it.. Because its the fool proof way.. no other way is.
I always pull the pin first (after the trailer brake if you want) then the legs, then hoses and electrical then I drive a bit forward like 50 cm, then I drop the air suspension of the prime mover so you can drive off without your trailer bumping off your prime mover. When the trailer is loaded, I always lift up the air suspension of the prime mover a bit AFTER pulling the pin.
When coupling the trailer I drive underneath the trailer a bit, stop before the pin, lift up the air suspension so the legs became loose of the ground, then I'll couple up the trailer. It will avoid your legs to bend and it will be easy to lift up the legs.
Horrible way to do it... if your trailer brakes aren't on and you pull the pin on a slight grade you will have a catastrophe on your hands... pull the pin last..
DC the leads first, then wind the legs down then pull the pin.
@@petetherealrelentless6542 that's why I've said to pull the trailer brake first (optionally), of course it's always better to do it but I know most drivers (like me) won't do it most of the time anyway. I've drove around Europe and Australia, never had a problem with any trailer, just use common sense.
@@_.A.J._ except common sense would be to do it the fail proof way which is pulling the pin last. Doesn't matter how far or where you've driven.
Can you do a video of how to back a trailer connected to the back of a truck.And how to back in to a tight spot between other trucks at a loading bay etc and around corners please.
Thanks for the suggestion Daryl - I will aim to do this.
Can you please do a video on u turns & when the load is empty/full? My boss drilled me last week when I did a tight u turn! He said I am ruining the tires, causing flat spots when i do a tight u turn in a small space.
Yes - I will do some more videos. Yes - the trick is to turn the steering wheels as you are moving... not when your truck is stationary.
Never seen the air taps on the suzies in the UK or EU - we just have the convenient quick couplings under full pressure. Hold on to them when you pull them otherwise they can knock your front teeth out if not paying attention
I have my canadien CDL. I'd love to drive in Australia for a year or two.
Suggestions?
From what I read people immigrating to Australia from, basically, a first world country can only get their car and motorcycle licences transferred over (New Zealanders all classes transferred except MC). But you could get a learner's permit for the type of vehicle that you are licensed to drive in Canada ie straight to semi trailer (class HC) lessons without having to drive a rigid truck (class HR) for at least one or two years. B-double (class MC) trucks are quite common in Australia even on arterial Metropolitan roads. If you don't do your test in a double clutch configured vehicle you get a transmission restriction on your licence. Truck drivers always needed. Come on down.
one thing i noticed you didnt explain, as i was taught today is sometime you need to dump the air form the prime, do you do that also?
Yea you should or he needs to have a special reason for it not to do it. But I can't think of one. I think in all cases it's better for the prime mover and trailer.
Why wouldn't you DC the leads first? If you wind the legs down and get called away from the truck or receive a phone call or someone else jumps in the truck to move it or any number of distractions and find out you have to drop the trailer elsewhere or move to another site and forget the legs are down you will likely rip them off.. however if you only DC'd the leads you will effectively be doing no more than a tug test.
So the safest and correct method would be:
1) DC leads
2) Wind legs down
3 Pull the Pin.
Thanks Pete - I like your procedure and explanation.
I'm in total agreement. Always disconnect Lines first when uncoupling, then legs and pin last. As you said it only takes a slight distraction and it's bye bye airlines and electric plug if you make a habit of disconnecting them last.
@@ianwatsons Thanks mate.. I like that you took my point the right way. 👍
@@mickeymoto60 yeh mate seen too many catastrophes over the years from drivers just suiting themselves and doing it a different way each time rather than the same safe way each time.
Now we need to talk about these drivers backing onto loaded trailers and doing their tug test while the legs are still down and in complete contact with the ground. 🤦♂ 😂
Whats the difference between the blue and red air lines? Is it just supply and return?
yes! send the air and return the air.
Get another cameraman next time.
Hey did you know that the camera GIRL is his wife?
@@paionebike3208 oops
Hii sar i am 🇮🇳 Indian
hi l like to jone show
Undo jaws first then legs
then lift air suspension in prime mover to raise trailer, wind legs down, drop air suspension, drive out.
Thats how you drop trailers. Pin is always last!
Very interesting
"undo jaws" last.
we use GLAD HANDS not Quick Disconnect couplings.
when u tired forget to disconnect and pull away ..the GLAD HANDS WILL POP OFF before causing damage.
Thats why you DC the leads before you lower the legs and pull the pin.. that way you cant pull away with them connected. Yay!
You made a mistake you forgot to talk about setting out your cones for safety
To drop a trailer? have you ever actually driven a truck????
If you need to watch this to work it out you should not have a licence
Yes! These videos are designed for beginners and people training to get a licence.
You are going to break your teeth
Why? he turned the air valves off before DC'ing
sem eye not semee!
How does 'Semi' sound.
It's Semi, not Sem-eye, or semee, or Sem-I.
