[FONT=Arial,BoldItalic][FONT=Arial,BoldItalic]think I found a dangerous error in the on-line training course at the school
I am going to attend.
On this question.If your air brake system safety relief valve opens a couple of times, you should have your system repaired. FalseThe online course says false...I think the answer is true.
Every DOT CDL manual states that the compressor governor shouldstop pumping air *cut out" at 125 psi. If the governor is not workingpressure will shoot to 150 and cause the safety release valve tokick in ? ALL DOT manuals state that If the safety valve releases air,something is wrong. Have the fault fixed by a mechanic.See below...
[FONT=Arial,BoldItalic][FONT=Arial,BoldItalic]5.1.2 Air Compressor Governor[/FONT][/FONT]The governor controls when the air compressor willpump air into the air storage tanks. When air tankpressure rises to the "cut-out" level (around 125pounds per-square-inch or "psi"), the governorstops the compressor from pumping air. When thetank pressure falls to the "cut-in" pressure (around100 psi), the governor allows the compressor tostart pumping again.
5.1.6 Safety Valve[/FONT][/FONT]A safety relief valve is installed in the first tank theair compressor pumps air to. The safety valveprotects the tank and the rest of the system fromtoo much pressure. The valve is usually set toopen at 150 psi. If the safety valve releases air,something is wrong. Have the fault fixed by amechanic.
- So if the compressor governor is broken or out of adjustment
the relief valve kicks in ? Is a broken or out of adjustment governor
a reason to have the fault fixed by a mechanic ?

It's not about reality or common sense, they want to know if you studied the material- so they want the answer they gave you in the course, not the actual, common sense answer. You're going to see a lot of similar situations in school- and in your first job.
Wait 'till you get in a driver's seat- when you're new this job is like a Monty Python movie, and they won't let you out.7122894003481 Thanks this. -
You right state CDL manuals say fix if air comes out. (imlpies first time)
Guess the answer is false because you should already have fixed it. LOL
This a Swift online test. !
[FONT=Arial,BoldItalic]The question is from Swift on line course.If your air brake system safety relief valve opens a couple of times, you should have your system repaired. FalseThe online course says false..[/FONT]
WTF - manual says fix it ???7122894003481 Thanks this. -
Nobody has answered this question ?
Why would swift teach that its ok for the pressure relief valve to trip a "couple times " -
If the latter is correct then look at it this way using multiple choice.
[FONT=Arial,BoldItalic][FONT=Arial,BoldItalic]1) If your air brake system safety relief valve opens once, you should have your system repaired.[/FONT][/FONT]
[FONT=Arial,BoldItalic][FONT=Arial,BoldItalic]2) If your air brake system safety relief valve opens a couple of times, you should have your system repaired.
[/FONT][/FONT][FONT=Arial,BoldItalic][FONT=Arial,BoldItalic]3) If your air brake system safety relief valve opens three times, you should have your system repaired.
[/FONT][/FONT][FONT=Arial,BoldItalic][FONT=Arial,BoldItalic]4) If your air brake system safety relief valve opens four times, you should have your system repaired.
[/FONT][/FONT][FONT=Arial,BoldItalic][FONT=Arial,BoldItalic]5) If your air brake system safety relief valve opens five times, you should have your system repaired.
[/FONT][/FONT][FONT=Arial,BoldItalic][FONT=Arial,BoldItalic]6) If your air brake system safety relief valve opens six times, you should have your system repaired.[/FONT][/FONT]
Which one would you pick? All are correct but which one is most correct using the CDL driver's manual as a reference? Why would you decide to wait to have the system checked after it opened more than once?

They always try to trick you. I just had to renew my hazmat and I swear they try to get you to miss questions. I love it when they give you like 3 answers that could technically be correct, but you have to know which one that #### book said.
