I bought my cat 277 new in 2003. No one has been able to tell me how to do that for 19 yrs until your video! For 19 f-ing yrs I fought this everytime I took off the 4 in1 and put my hammer on if there was a temperature change! Turn the key on hit park & move the aux control to both positions. Piece of cake. Thank you so much!!
Nick ,
LOL...You made my day brother!
Sometimes they spend so much time making the manual readable in 75 languages that they miss the stuff that matters!
Merry Christmas!
-Shane
Thank you so much for making this video!! it really helped me much appreciated
Thanks Shane. I'm new to skid steers and have been fighting it for a couple of weeks.
That Guy,
I fought it for a long time when I got my first auxiliary equipped machine.
A fella would think that they would smack a "How to" sticker on something like that but they dont.
Have a SUPER weekend!
-Shane
Thanks ! I needed that information .
Flat Mountain,
I spent so much time wrestling with mine that once I got the process sorted out, I knew it would help folks!
Thanks for taking the time too comment!
Have a wonderful weekend!
-Shane
You are a life saver I love you
LOL... I'm glad you found the video helpful!
I'm getting a lot of love from folks with furnace problems during this most recent mean cold snap lol
Stay safe, healthy, and WARM!! lol
-Shane
Good advice and good video
Thanks for the view, and thanks for the comment!
Stay safe and stay healthy!

Grate video I will tried this today
Connecting the hoses together from the attachments when not in use has helped me a lot. My New Holland skid steers don't have that button. The hoses will build up pressure from sitting in the sun.
Michael,
Yes sir! I always connect my hoses together.
Keeps the dirt out of the fittings and helps to keep them equalized
I hadnt considered that they build pressure sitting in the sun but that makes perfect sense!
Excellent comment!
Thanks again,,

@@AHandleOnThings p
Thank you sir!!
Shane thanks when I use my graffle brush bucket open slow and close slow any was fast now slow what to do please and thanks again
Sir can you help me , i bought a skid steer loader GEHL 4635SX , the issue is when starting the engine it moves forward automatically and it will stop only when engine turn off.
Hahahaha.... omg. I have not checked to see if I even have that button, but I thought I was just too weak and that everyone else was having no trouble at all. At least now I know we all struggle with this.
Do you have a video on operating a grapple ? I have a similar m/c ( T190 , panel is like yours ) I have an issue with aux hydraulics not working . I put a grapple on it , but not functioning with the thumb switch even with the hydraulic light on . What am I doing wrong ?
Mr Bill,
Ensure that you have enabled the hydraulics on your control pad. (mine is on the top left of cab)
and then you should be able to sort out what control button is programmed for supplying flow to the aux set up. Each machine is a little different but it is going to be pretty basic. Just a two position flow valve setup.
If you dont get it working, check your aux system with a different implement to ensure that it is working. Isolate the issue and then troubleshooting becomes easier
LEt us know what you come up with!
-Shane
What does it look like on an older model?
How do you release pressure on the older models that don't have the button ?
Try attaching one hose. (Usually one hose will go on and the second one gives you trouble due to pressure... ) Then after trying and failing to attach the second hydraulic line.... DISCONNECT the FIRST hose you JUST HOOKED UP and the attach the OTHER One...
THEN attach the FIRST line again...
That used to work to bleed off the pressure every time with my last machine.
Let us know how it works out for you!
-Shane
I have 1993 7753 and have always had the problem of plugging in the auxiliary hydraulic lines. One goes on no problem and the seldom goes in without cracking the fitting and bleeding off pressure. You are supposed to turn the key off and in the same motion turn it to pressure relief. It might work 2 of of a 100 times. Have talked with Bobcat and they have no ideas. Do you. I have contemplated putting a toggle switch to power up the relief valve for a few seconds but I shouldn't have to do that. I bought this machine new in 1994. Thanks
Unfortunately I don't have any ideas for that particular system. Sorry.
-Shane
@@AHandleOnThings Ok, thx.
Great! Do you run the skid steer at a certain rpm when you push the button? My bobcat doesn’t die (or at least after more than a minute it doesn’t die)
Also does the safety bar need to be up, down or doesn’t matter?
Hi I have a question and I'd appreciate if you could help me out I have a bobcat compact excavator and one of the thumb hydraulic line snagged and ripped off but it broke and all the hydraulic fluid spilled out I got a new hose and it's all back and put more hydraulic fluid do I have to "purge the lines" ? And how I can't find a spot to hook up a purge hose .. its the bobcat 331
There will likely be a different "factory recommended" process for bleeding the air out of your system depending on what the broken hydraulic line was serving.
While I dont claim to know the process for your machine and I dont know which ram your line was serving, often it is as simple as removing the OUT-FLOW line from the affected ram, and then collapsing the ram to an "empty" state to bleed the air from it and then hook the line back up and supply the hydraulic fluid to the ram again.
Again, I dont have enough info to promise you that this will work, but that is a commonly followed procedure.
Let us know how you come out!
-Shane
Do you know where the auxiliary lines lead too? I have an 853h but the auxiliary lines got disconnected by the previous owner so I don’t know where to connect them back into
Mine follow the inside of the lift arm on the "drivers side" back to the engine compartment. They are obscured once they hit the engine compartment so I cant tell you the routing from there. Sorry.
I would look for a maintenance/parts manual and there should be something there I would guess.
Let us know how you come out!
Stay safe!
-Shane
God bless you 😂
Yeah but what if the lines have pressure? How do u release that?
The pressure release button should release all pressure within the system if the hydraulic lines are connected to the machine.
-Shane
👍
Thanks for the view Joey!
Have a super evening!
-Shane
I have a New Holland. It doesn't have a pressure release button. How do I connect the aux attachments?
G.A. Wilson,
I haven't ever owned a new Holland, but when in doubt, shut the machine down and that is often enough to open the pressure releases.
Optionally, give your local New Holland dealer a shout and they can help for sure.
Thanks for the comment and be sure to let us knw what you come up with!!
Stay safe!
-Shane
No.. Shutting off machine does not help. Calling a qualified NH tech does not help either. Pretty much just work at it for about an hour each hook up while bitching and moaning the entire time. If rhis doesn't help just cry for a few minutes when you become very fed up with it. Usually none of this works.
But mine does t have that switch
I have the same model as you in your video. Cant get my front hydraulics to work. I'm using a titan tree puller attachment. Im tried all my thumb switches to no avail. I have the hydraulics light do come on. Any suggestions? Am I possibly not turning something on? Im new to this machine. Thanks
Right below your fuel gauge there is a button that says "maximum flow only/variable flow"...
Push that after you have all of the hydraulic lights lit up and then try your switches... That enables the switches on the sticks.
Let us know if that solves your problem!
Stay safe!
-Shane
@@AHandleOnThings , should it be in max flow or variable flow ? Mine doesn't work with either light on .
Any ideas what to do if this tip doesn’t work?
It would depend a lot on what machine you have, some of the skidsteers just function differently
Sorry I dont have a better answer for you.
-Shane
No need for apologies! I really appreciated the video. My issue ended up being the hydraulic connections on the rental attachment. I was able to relieve the pressure in the hoses with a hammer and a long bolt. Thanks!
@@backlund5 I'm glad you got it figured out!
Sometimes the fix is to get a bigger hammer!
lol!
Hope you have a super weekend!
-Shane
i have faught sometimes 2 of us to get them hooked up
I know it man... IT can be a real devil if the pressure isn't released first. I learned a LOT of four letter words before I figured this out.
Have a great day!
-Shane
I can’t get them off
Dawn
Generally the problem is needing to depressurize the hydraulic system.
Occasionally you may be accidentally be pushing on fittings that are supposed to be pulled to release (or vice-versa)
Another possibility is... there is a little bead that is essentially a ball bearing that needs to be aligned with the collar to allow it to be slid.
Let us know what you come up with!
Thanks,
