New to automatic slack adjusters. Any adjustment neccesary?

You can do it the same way you always have on Self adjusting slack adjusters to, i do.....Although if you are having to do it often, that means they are not doing the job and need to be replaced..

 

No just a half inch or a 9-16th, find big nut, crank it down. tap drum thud thud brakes on. Back off half a turn until you hear Mr Ding Ding while tapping on drum. Done.

Several times a day dive under there and adjust them.

When we hit auto adjusters I just stomp the service air to the floor 7 times and hope the DOT man pulling on them sees them in adjustment.

 

Not necessarily. Automatic slack adjusters only really adjust during HARD breaking. A careful driver that never hard brakes can easily get brakes with automatic slack adjusters out of alignment.

A good recommendation is to make several HARD brake applications at the end of a shift (but NOT with the spring brakes on at the same time!) to force the slack adjusters to ratchet. I also train my drivers to do this when they get pulled in for an inspection. Five or six full pressure applications before they open the door to go talk to the inspector.

 

To check them ..air I system .chock wheels release brakes ..pull on slack adjuster it should only pull out about 3/4 to 1 inch..if more adjust by tightening 7/16 bolt in until it stops the back of 1/2 turn..it will make a popping noise sounds like you are breaking something when backing off. but it's a normal sound...good to go
