SOURCE: I have a dewalt 3750

I worked at a tool rental center while attending college and learned many tips and tricks about Dewalt and other brand pressure sprayers. Your machine probably has a 13 hp honda and has max pressure of about 3500 to 3700 psi. Most of the problems that customers had were engine related due to severe working conditions including totally wet engine /plug, wet air filter, and or other problems that were easy to remedy. We would set the pressure regulator to minimum pressure and explained to the customer how to increase the pressure as necessary but only after the engine was completely warmed-up to running temp to prevent engine stall. Your machine has a throttle lever between the tank and carb that should be set to max if you are going to set pressure at or neer max range. Most cleaning jobs do not need much pressure. Use lowest pressure to get the job done. Your engine developes around 13hp at about 3600rpm. If you want to maximize the life of you sprayer, then use your machine at about 70% of capacity or about 2000 to 2500 range that will allow you to run your engine slower increasing lifespan. Your sprayer is likely rated at 4 gallons per minute so make sure that the tip is that capacity. The tip has the size stamped which would show the fan degree and flow in gpm. The wrong tip, say a 3.5 gpm will strain the engine to point of stop because the smaller tip increases pressure. Most engine stall is due to high pressure setting on new machines. Lower pressure when warming-up machine and use max pressure rarely when necessary to max life. Please email for other information/questions or simple tests to determine faulty parts, good luck.

SOURCE: pressure washer stalls out when wand nozzle is released

common for not starting unless trigger engaged as you are turning the pump as well as engine creating pressure,as for stalling pump has unloader valve which is probably in need of grease(use good silicone grease)this allows water to ciculate when trigger released.

SOURCE: Lack of pressure after releasing the trigger on the wand

Hello awcockerill:
This sounds like the bypass (unloader) valve is sticking. Here is a diagram of your machine's pump. On page 2.4 see part #1. The top of this assembly is a black plastic cover. Remove all of assembly # 1 carefully. Under that is part #8. This is the bypass valve. You need to pull this out, check that the o-rings are not bent, worn or damaged, then lube it good with a VERY VERY good waterproof grease. Re-assemble it and all should be well. The part numbers are on the diagram but where to get them depends on were you live. Karcher web site may give you a number to call. Good luck.

Karcher electric power washer480 .pump runs on when trigger is released there are no leaks . Also i can not turn machine off at the main switch.


If you are unable to shut off the pressure from the wand, there may be an issue with the unloader valve that is stopping it from switching into bypass mode when the trigger wand is released. The unloader valve is designed to respond to the spike in pressure created when the trigger wand is released, and to divert the flow of water coming from the pump to bypass the pressure hose and flow back into the intake end of the pump. If the unloader valve fails to switch into bypass mode, water may continue to flow out of the trigger wand. This may also cause damage to the wand. If you are unable to shut off the pressure from your power washer, stop the engine and discontinue use immediately. The unloader valve should be removed and possibly replaced if found to be malfunctioning. The inability to stop the flow of high-pressure water from the wand can be dangerous and should be fixed before continuing to use the machine.

Black and decker electric power washer nothing coming out of wand all water coming out trigger.


Either the pressure tip or wand are blocked or the valve in the trigger is broken. Remove the high pressure tip and either try another tip or pull the trigger without a tip on the wand to see if you have the same problem. If available, try another pressure gun on the hose.

Trigger don't release


I have a hose and gun that fits the McCulloch FHH18A that I no longer need as I had to buy a complete universal hose/gun and wand unit since I had broke the wand and the replacement wand was no longer available. If you are interested in it, email me at burmakow@nwciowa.edu and we can figure out a price.

As soon as I turn the water on, it comes out of the gun and high pressure turbo wand even with the machine off. I used it yesterday with no problems. It does this without even pressing the trigger. ...


Hello,
This part should be available from the manufacture, have you check their website. It is normal when you turn the water on for a small string of water to come out the gun when you press the trigger even when the engine is not running.
Thanks

My Snap-On 2000 PSI pressure washer is leaking through the trigger handle. I have no pressure coming out of the wand but the motor runs.


The fitting for the trigger is cracked. It happened to mine because I did not make sure the wand and hose was drained before winter came. The water left in the wand expanded and cracked the trigger housing. The problem is that the trigger piece is easily replaceable, but it is not available. Alltrade makes you buy the complete wand.

Winchester model 88. with the trigger assembly


Less Than Perfect
The Model 88 had its faults. The trigger moves with the lever and the resulting linkage to the sear results in a rather spongy, creepy trigger break. If you want to see your gunsmith turn pale, waltz into the shop with an M88 and ask for a crisp three-pound trigger.

If you already have taken the gun apart, don't be afraid to hone the parts on a stone , keep them flat, you don't want anything rounded off. Especially the sear. I found that quote up top from a winchester sight,
