Back to the dolly first, they should have been post-tripped so most will be good to go.
It is proper methods to pre-trip your dolly, whether is was supposed to be post-tripped by the previous driver or not.
And never, ever, trust anyone else for equipment that you are pulling. It is your life.
Pre-trip the dolly.
4-ways should already be on when on the yard.
I never could understand why half the drivers drive around the yard with their 4-ways on. At UPS, 4-ways are to be used when backing. On the road, they are to be used when stopped on the shoulder or when going considerably slower than other traffic.
In the yard, everyone is going slow and drivers are using their 4-ways for backing and going forward. Talk about confusing?
Hand valve can't be pulled unless hooked to trailer with air applied.
Yes it can. It does not supply any air since the trailer air supply is not applied, but it does activate the brake lights, which need to be checked on the dolly when pre-tripping the dolly before even moving it.
raise landing gear, hook up lines
Not to nit-pick, but it is hook up lines, apply air, then raise landing gear.
Different ways to do some of this, find a routine and stick with it.
Exactly. Find a routine that works for you and stick to it.
If you ask me it seems stupid to have a week of training and build one set.
Here, we have a week of production before obtaining your CDL. During this week, you should be building at least one set daily.
