So I was at a job yesterday and was parked on a fairly steep hill. About 25 mins into the job my TM shuts down. I thought maybe it overheated because the heat exchanger was scolding hot so I let it cool down about 15 mins. When I try and start it back up it will only start at very low rpms (about 1,000) and roughly 10-15 secs into it shuts down again. I checked the oil and gas to the engine and both are good. I'm fairly new to the bizz still and have little to no engine knowledge what so ever. Any suggestions would be helpful.
It just might be your engine shutoff low oil shutoff switch, just due to it being on a steep hill. Did you try to run it on more level ground?
How old is your machine? Maybe it's the low water sensor for the water box, if you have a water box. What kind of truck mount is it?
Do you have a float in the holding tank, might be stuck. Could be the angel got it into a funky position. Worth a look.
Give Ben at Amtex Equipment a call. He won't be happy that you bought a Chemtex, but I'm sure he will be able to tell you what is wrong with that machine. Do they not have a customer service line at Chemtex? If it's brand new, there should be someone there to help you
Haha, god this is embarrassing. Yah, chemtex does have a hotline to call if you're having problems but I called them about 2 weeks ago and the guy I talked to was an ass and proceeded to tell me "Oh well, sorry I don't know what the issue is. I don't actually work for chemtex anyway so, good luck." Basically implying that beyond general knowledge answers, he wasn't going out of his way to troubleshoot anything because he's not getting paid. [MENTION=13493]Dirty Money[/MENTION] - Yah it does have a float in the waste tank and Iv messed with that already too.
Does it have a fresh water sensor? That's where it will shut down if the water pressure supplying the machine isn't giving you enough water to prevent damage to the water pump. When you increase the RPM, it might need more water pressure to feed the water pump. Also, You can check to see if the positive wire on the battery is tight. If it's loose, it can shut the machine down when you reach high rpm
RUGSNSUDS, Sorry to see that you are experiencing hard time with your unit. Start by checking to see if your engine's oil smells like fuel (gas). Amtex Support Team
No, the oil doesn't smell like gas. It starts and will run for about 30 secs at 1000 or less rpm then die. If I try to up the rpms a little after I start it, it jumps up there for about 3-4 secs then dies.
Sounds like a fuel issue for sure. Often times like kingjoelking mentioned if you are low on fuel, sometimes even if you have 1/4 tank of gas and park on a hill this can happen. After going on level ground sometimes the there is enough fuel to start the engine. Most truckmounts have the fuel tap installed so that the machine will run out of gas before the van does so that you don't use up all the fuel and get stranded on a job. Fill the tank up all the way and see if that helps. If you still have the problem with a full tank of gas the fuel pump may have a hole in the diaphram from running dry. To replace the pump should only be about $50 or so. Most machines will use a 5 to 9 psi pump and some use a 2.5 to 4 psi pump. here is a link to each one. Should be an easy enough job to do yourself. http://www.autozone.com/autozone/ac...&fromString=search&itemIdentifier=963381_0_0_ http://www.autozone.com/autozone/ac...&fromString=search&itemIdentifier=254789_0_0_
One other thing before you go buy a new pump, there are several things on most newer truckmounts that will kill the power to the fuel pump like mentioned above. It could be low oil, low to no inlet water pressure, a high heat sensor, the float shutoff in the waste tank, and possibly other things that may varry by machine. Even if you have checked all these things the switches or sensors for each of the listed items can go bad so even if there is enough oil the sensor may not function right and shut off the fuel pump. You mentioned that you had a solution temperature overheat, the high temp sensor may be bad. (this is one thing that drives me nuts about newer machines, there are so many little things that can go wrong). To test the fuel pump, disconnest the electrical wires to the fuel pump and get some extra wire and hook the fuel pump up directly to the battery and then try to start the machine. If it fires up and runs the issue is with one of the sensors mentioned, if it still will not start then I would replace the fuel pump. Once you have tested the pump be sure to reconnect the proper wires and don't leave the pump wired directly to the battery.
Check the jet in the water box. Take it out clean it. Take out the fuse for hi tempshutdown and try running for short time. Make sure the wastetank is empty. Lee
Update: Ok, I started tm again today and it stayed on. It ran about 1,000 rpm really rough for a few mins and gradually got better until it was smooth I slowly cranked it up to about 1400 or so and let it run for about 15 mins. After it was good and warmed up I tried to turn it up higher and it sputtered out and died. I know you're thinking "well it just needed to warm up, that's all". Keep in mind it was running perfectly fine before this whole fiasco began and it was plenty warmed up when it mysteriously died.

I know this is a dumb suggestion, but did you make sure your gas didn't have water in it? And by that I mean use a completely different gas tank with a fresh load of gas.
