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: I have purchased a Dewalt 3800 PSi cold water

check to see how hot the water can be, ti should be on the unit or in your book. also your amps should be no less than 15amp, long core can over heat the motor. if your unit can't handle hot water it will melt the valves

SOURCE: low pressure

hi some valves at cat pumps need a 100 psi pressure to open and close correct. when there is air in the pump the valves wil not open and close till air is bleeded. take of highpressure hose, open watertap and bleed pump till no more air comes out. reconnect all hoses and try again. if there is no more air in the pump and its still not working, i should think its the pump.

No pressure!!


You have an air lock. Here's how to fix it:
1. Connect the hoses, and turn the water on. Work the supply hose in such a manner as to displace any air in high points in the hose through the pump. Let the water run for several minutes, then connect the gum. Turn the water back on and let the PW come up to 'house' pressure, and pull the trigger to depressure the system rapidly. This displaces any trapped air. Do this several times, until you get no traces of air at the gun. Crank the PW; it should come up on full discharge pressure. If it does not, shut the engine off, and repeat the displacement maneuver. This time, start the engine while holding the trigger of the gun down. This will act as an unloader, and should give you full pressure.
Best regards, --W/D--
