COOPER

Yea, somebody made a killing selling them new ones I bet! LOL I am sure they are contracted out through a large corp. or something though. Probably one that received a bailout!!!!! HAHA

A friend of mine has a cousin who owns a scrap metal yard. The guy has a contract with a military base to haul off their scrap as needed. Well my friend calls me the other day and says that his cousin has a big pile of military hot water pressure washers and that I could go and buy any good parts at scrap prices! I go out and this is what is I saw. AT LEAST 300 new NEVER USED hot water units that have been DESTROYED so no one can use them!!!!!!! They are hydralic driven with a belt drive Cat pump, all stainless frames (painted green), and have never even had a belt ran on the pulleys!!!! (paint is still new in the belt groove on the pulleys!) IF they only cost $5000 a piece new, that would be $1,500,000 worth of WASTED TAX MONEY!!!!!!! I would be willing to bet these washers cost at LEAST $10,000 a piece though, cause they were very nice BEFORE they were destroyed. All of the pumps had the heads removed and holes drilled through the main case, the hydralic units were also either smashed or had holes drilled in them, the burners had never been used either, and the whole units look to have been smashed by forklift or something! There was also THREE more piles of military stuff (one was some kind of pump but not sure what kind and other pile i didn't really look at) that all looked to be new, unused, AND destroyed!!!!!!! There is NO TELLING how much WASTED tax money is in those piles!!!!! Here is a couple of pics of the pile of pressure washers. There is probably enough hot water units in this pile to give one to every contractor on this board and now they are just junk!!!! Sorry to ramble on about this but this really struck a nerve with me!!!! I knew the government wasted lots of money but this is pathetic to just throw away NEW never used stuff and on top of that DESTROY it so nobody else can even use it!!!!! Oh and I bet after these left they order MORE new ones to replace those!!!!!!

If that is the problem, I would also change the oil! The gas can leak past the rings sometimes in those motors and get in the oil. Try and remember to turn the gas off after every use and it won't happen again.

Is the unloader kicking into bypass when you release the trigger? If not you probably have a bad unloader. If it has a pressure gauge, check to see what the pressure gets too BEFORE the pop off valve "pops off". If it is a lot higher than the machine is rated for then you probably just need to turn the knob(if it has one) down on the unloader. If it doesn't have a knob then loosen the bolt at the top and (unless its a zk1 or k5 unloader) turn it counter clockwise. If its one of the above unloaders turn it clockwise. If the pressure doen't get much more than the rating on the machine, then you either have a bad unloader or the pop off valve needs adjustment. Most time the pop off can be adjusted with an allen wrench. Just turn it clockwise a little (maybe a half turn) and try it again.

The 7.3 is a better motor and I think better mileage too.

More than likely, its an unloader problem.

What about propane? They could be ran indoors.

No Ron you will need a much bigger generator probably around 15,000 watt. 10,000 may work, but i would think it would be close. May take a little more than the 10,000 watts to start the machine. One thing about the electric machines is that you can either buy one with a full shut down (when you let off the trigger the entire machine shuts down either right then or with a built in timer), or can install one if the machine doesn't come with it. I believe this greatly improves the life of the machine.

If your machine has a pressure type unloader this switch needs to be installed between the pump and the unloader. If the pressure switch is installed on a pressure type unloader directly it won't work properly. The unloader traps the pressure in the hose when the trigger is released and will keep the switch depressed and the burner running.

Definately the Hydrotek or a Pressure Pro

Only time we don't work in the rain is when it is storming and we don't try to strip wood in the rain. As long as its not lightening, we are working.

Probably the high limit swich will look kind of like a plug with two wires running into it going into a fitting somewhere after the burner.

More than likely, its the fuel filter.

You can make that with a regular downstream injector. Get a reducer to take the "pump" side of the injector down to 1/4" and get a 1/4" quick connect plug and put it on that end. On the "out" end (the end that the arrow is pointing toward) put one of those adjustable "push/pull" nozzles on and you have the same thing.
