4000PSI 4.0GPM Gas Pressure Washer with CAT Pump

The Yamaha PW4040 4000PSI 4.0GPM Gas Pressure Washer is an ideal blend of power, function and portability. Rated at 4 gallons of water output per minute at 4000 pounds per square inch, the Yamaha pressure washer is powerful enough to tackle any cleaning job. The Yamaha PW4040 4.0 GPM gas pressure washer operates with an efficient Yamaha MZ360 engine able to run at 3600 RPMs and equipped with idle-down technology that saves fuel costs and extends the life of the engine. The MZ360 of the Yamaha 4000 PSI pressure washer powers a Cat Triplex Pump®, an all-brass reciprocating high-pressure pump with an industry reputation for high performance and durability.The Yamaha heavy-duty pressure washer has an intricate nozzle, nozzle tip and hose arrangement that makes it easy to adjust power washing for different applications. The nozzle head pivots to 3 separate spray angles for underside, overhang and straight-on power washing. The grip handle of the Yamaha 4000 PSI pressure washer rotates fully on the nozzle gun and unlocks and locks quickly in place for enhanced ergonomic control. The nozzle gun houses 5 quick-fitting nozzle tips, each one spraying at a different angle. The Yamaha heavy-duty pressure washer has a rugged, flexible hose consisting of rubber-coated braided steel and extending a full 50 feet in length. All nozzle and hose connections have corrosion-resistant brass fittings. The durability of the Yamaha 4000 PSI pressure washer also comes from its steel wheels and axles and steel hand-truck roll-cage frame. The washer transports easily over any terrain with nonpneumatic tires that never go flat and a sturdy handle that folds flat when the washer is stored. Several accessories are available for the Yamaha heavy-duty pressure washer, including a gutter cleaner, an accessory hose and a hose-adapter kit and rotating nozzle surface cleaner.

Customer Reviews
Rated 5 out of 5 by from One small problem I'm sure ACME will fix This is one awesome pressure washer! The best feature is the automatic idle when trigger is released. Mine will not feed soap with the soap nozzle installed, but feeds it like crazy with no nozzle at all. This indicates a faulty or undersized soap injector, which is an easy fix. I hope Yamaha or ACME does the right thing.

Rated 4 out of 5 by from Yamaha PW4040A Received delivery fast and without shipping damage. Only issue was if was shipped tractor trailer which could not deliver to my house and had to meet driver with my pickup. Unit assembly straight forward and after adding oil, fresh gas and turning in water it started in three pulls. Amazing pressure and water volume perfect for my applications. Only drawback is the size and weight which makes transport a two person job

Rated 5 out of 5 by from Great value Just started using this washer today. Assembly was pretty easy with two people. Filled with the oil provided and gased it up with non ethanol gas. It actually started with the first pull of the starter rope. That was a surprise. You would think it would take a few pulls to get gas to the engine while new. Did three sections of a double wide drive way to check out the new tips and a surface cleaner with straight wand I bought separately. The straight wand does not fit on the Yamaha surface cleaner because the QD stub on the cleaner is too short or the QD sleeve on the wand is too long. Anyway, I put the wand on the lathe and took off about 1/8" off the QD sleeve and it fits perfect now. Everything worked just fine. The washer has plenty of power and I really like the idle down feature when you release the trigger. The unit is fairly loud under load though. Had to turn the exhaust towards the neighbor's yard to continue comfortably. Ear plugs would have been fine also. I like the cart design better than most washers on the market. You can use the handle like a dolly and roll the unit around easily. Others have it backassward, imo, where you have to lift the back end off the bumper supports and literally carry the light end up while trying to walk it to the work location. You have to assume the people that designed them that way never used them. Anyway, the PW 4040 has very heavy duty construction and appears to have been crafted with care. Looks like a keeper.
