Honda GX200 Engine – Trusted Power for Professionals

At the heart of the pressure washer is the Honda GX200, a commercial-grade engine renowned for:

• Easy starts with advanced recoil design

• Long life and low fuel consumption

• Quiet, smooth operation

• Overhead valve (OHV) configuration for optimal performance

• Precision-built components that resist wear in extreme work conditions

Backed by a 3-year warranty, the GX200 is designed to withstand continuous use on the jobsite and deliver reliable starts and consistent power, day in and day out.

Triplex Pump – Built for Daily Use

Unlike less durable axial pumps, this model is equipped with a triplex plunger pump—the gold standard for high-pressure, high-duty cleaning. Triplex pumps are built for:

• Long service life, even in continuous-use applications

• Lower heat buildup, reducing wear

• Serviceable components, such as seals and valves

• Smooth operation, with fewer pressure fluctuations

The built-in unloader valve manages system pressure to protect components while delivering consistent spray performance. It's ideal for commercial users who need a washer that lasts longer and performs better.

50-Foot Steel-Braided Rubber Hose

The included 50' high-pressure hose is designed for rugged use. Its steel-braided inner core reinforces strength under pressure, while the rubber exterior provides flexibility without cracking, even in colder temperatures.

• Abrasion-resistant outer layer

• Kink-resistant construction

• Quick-connect fittings for easy setup

• Long reach reduces the need to reposition the unit constantly

Whether you're cleaning around a vehicle or covering a long stretch of concrete, this hose makes sure you can keep working without interruption.

Quick-Connect Spray Nozzles for Every Job

The washer includes four quick-connect spray tips that attach directly to the wand, giving you precise control over the spray pattern and intensity:

• 15° (Yellow) – High-impact cleaning for tough stains

• 25° (Green) – General cleaning on most surfaces

• 40° (White) – Gentle rinsing or delicate surface washing

• Soaper (Black) – Low-pressure wide spray for use with external soap systems

Switching tips takes seconds and ensures that you can handle everything from delicate siding to stubborn grease with the right tool in hand.

Tough Frame, Mobile Design

Mobility and protection are key when using a pressure washer on jobsites or rugged terrain. This unit features a heavy-duty powder-coated steel frame, built to resist corrosion and endure the impacts of daily transport and operation.

• Integrated handles make loading and lifting easier

• 10" flat-free tires roll over rough surfaces without deflating

• Low center of gravity adds stability during operation

• Compact footprint makes it easy to store and transport

Whether it's rolling across gravel or resting in a utility trailer, this frame is ready for whatever your workday throws at it.

Cold Water Only – External Soap Compatible

This unit is optimized for cold water cleaning and does not include an onboard detergent system, which reduces internal wear and complexity. If soap or degreaser is needed, simply pair it with an external downstream chemical injector or foam cannon for effective application without compromising pump integrity.

The Case IH C3865HA 3,800 PSI 2.5 GPM Cold Water Gas Pressure Washer is built to handle demanding work with ease. With commercial-level performance, premium components, and a compact, durable design, it's the ultimate tool for anyone serious about getting the job done right—without unnecessary complexity or downtime.
