Description
The DEWALT 61147S is a cold water gas pressure washer rated in the listing at 3300 PSI and 2.4 gallons per minute, built on a welded steel frame around a 208cc DEWALT engine. It is one of the better documented gas machines in this catalog, and there is one significant conflict between the listing and the description previously carried on this page. This review works from the published specification fields and feature bullets. We do not own or operate the machine.
Carbon monoxide comes first on any gas machine
This engine emits carbon monoxide, a gas you cannot see or smell that can kill quickly in an enclosed space. Never run it indoors, in a basement, in a shed, in a crawl space or in a garage, and opening the garage door does not make a garage acceptable. Operate outdoors only, well clear of windows, doors and air intakes, with the exhaust directed away from the building and away from where anyone is standing.
Refuel outdoors with the engine cool. DEWALT publishes a specific instruction on this listing: keep the maximum fuel level half an inch below the bottom of the filler neck to avoid spillage. Follow it, because spilled fuel on a hot muffler is the other way these machines cause serious injury.
Who this machine is for and what it settles
The 61147S settles whether you need to move from electric to gas. At 2.4 gallons per minute it moves roughly twice the water of a typical corded machine, which is what makes a long driveway a job of an hour rather than an afternoon. DEWALT’s own copy names deck cleaning, wood restoration, paint preparation and graffiti removal, and positions the unit for the cleaning professional as well as the homeowner.
The frame is 41 inches long, 21 inches wide and 24 inches high with a published weight of 64 pounds and 10 inch pneumatic tires. That is a machine you wheel across a yard, load into a truck with help, and store where it will not need to be lifted often. Anyone who wants the same work done without the fuel, the exhaust and the weight is looking at the wrong category and should compare against the corded electric section, accepting a large drop in flow rate.
The specifications that matter
DEWALT publishes a 208cc engine, a maintenance free OEM Technologies axial cam pump with a thermal relief valve to prevent overheating, a welded steel frame with a powder coated finish, a MorFlex quarter inch by 25 foot high pressure hose described as non marring and abrasion resistant, five quick connect nozzle tips at 0, 15, 25 and 40 degrees plus soap, an ergonomic spray gun and a 16 inch steel wand. Customer feedback is recorded at 4.2 out of 5 across 544 ratings, and the sales rank fields place it 73rd within pressure washers and 13,461st across patio, lawn and garden at the time of capture. Country of origin is given as USA.
The five tip set is a genuine advantage over the three nozzle machines elsewhere in this catalog, because it includes a 40 degree wide fan. That is the tip you want on siding, vehicles and painted surfaces, and its absence forces awkward workarounds on machines that omit it.
Manual start, despite what this page used to say
The product title on the listing reads “3300 PSI – Manual Start”. The description previously published on this page claimed effortless starting with an electric starter, which the listing does not support anywhere. We are naming that rather than quietly correcting it, because a reader who bought on the strength of an electric start would have been misled. Nothing in DEWALT’s published bullets describes a starter battery, a control panel or a push button. If electric starting is what you want from a DEWALT gas machine, the model that publishes it is the DXPW3400PRNB-S, whose listing describes a battery operated starter and states that the battery is sold separately.
Using it correctly
At 3300 PSI the jet can inject water and contaminants through skin, producing a wound that looks like a small puncture and is a surgical emergency. Never point the wand at a person or an animal, never steady a workpiece with your free hand, and wear eye protection and closed footwear every time. Keep bystanders, children and pets entirely out of the work area, including behind you.
Start every surface with the 40 degree tip and move narrower only if it is not working. The 0 degree pencil jet has almost no safe use on a building: it will cut into wood, blow mortar out of joints and remove paint down to the substrate in a single pass. On lap siding, work downward and diagonally so water is not forced up under the laps and behind the cladding. On decking keep the tip parallel to the boards and in constant motion. Test on a hidden section first.
The thermal relief valve protects the pump when the trigger is left released and the water in the pump head heats up, but it is not a license to leave the machine idling with the gun closed for long periods. Shut the engine down between tasks.
Limits and gaps in the published data
The listing is 49 state compliant, meaning it is not certified for sale in California. If you are in California, this machine is not an option and the CARB certified alternatives in the gas powered section are where to look.
The field labeled “Specification Met” reads “oem”. That is not a standard; OEM Technologies is the pump brand DEWALT uses, and it has been dropped into a field intended for certifications such as CETA or PWMA. Read it as an import error rather than a compliance claim.
Not published: fuel tank capacity, run time per tank, oil type and capacity, whether a detergent tank is fitted at all, and the warranty term. A soap nozzle is included but no tank is described, which usually indicates a siphon tube drawing from an external container. The 3300 PSI figure is a maximum with no companion working pressure figure.
How it compares within this catalog
The closest cross shops are the Simpson CM61083, which uses the same class of 208cc engine and pump at a slightly higher published pressure, and the Westinghouse WPX3400, which publishes a higher flow rate and an onboard soap tank. At a lower price point, the BILT HARD 3500 PSI unit publishes similar headline numbers but with several specification fields that do not survive scrutiny.
Who should buy it and who should not
Buy it if you want a documented pump, a full five tip nozzle set including a 40 degree fan, a steel frame and a substantial feedback history, and if you are outside California. Do not buy it if you need an electric starter, because this model does not have one whatever the previous description on this page said, and do not buy it if you need fuel capacity and warranty details settled before purchase. Run it outdoors only.
