Power
With a 163cc engine powering it, the axial cam pump of this unit is capable of achieving a pressure of 3100 PSI (approximately 52 times greater than that of a standard garden hose) and a flow rate of up to 2.4 GPM (CETA-certified values). Corresponding to these values is a cleaning power of 7440 Cleaning Units.
The CRX 165 engine of this gas pressure washer is activated by pulling a starter cord, following a traditional approach.
Containing gasoline, the pressure washer's fuel tank can hold a maximum of 1 gallon.
Design & Handling
Enhanced mobility is a key feature of the Simpson MS61425, thanks to its hand truck design. With its strong steel frame, the assembly is built to last, providing stability and safeguarding internal components, even in challenging environments. The handle adds to the MS61425 convenience of transport.
Weighing 63 lbs, this unit offers a manageable weight that allows for easy handling by most individuals. Its 163cc CRX 165 engine and steel frame account for a good chunk of that weight. Yet, its two 10" pneumatic wheels ensure the MS61425 remains effortlessly maneuverable.
Main Features
The Simpson MS61425 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Though lacking a dedicated soap tank, the device ensures detergent supply via a siphon hose. Attachment of a soap nozzle prompts the pressure washer to automatically introduce and blend the detergent with the water.
- Pressure hose: When not in use, the unit allows for tidy storage of the included 25 ft ⌀1/4" high-pressure hose using a set of easy-to-use straps, ensuring convenient organization.
- Spray gun and wand: Both the classic ergonomic spray gun and its steel wand may be conveniently stored in a side hook.
- Nozzles: Below, you'll find a table outlining the 4 included nozzles and their recommended surfaces.
