DESCRIPTION
4,200 PSI 4.2 GPM Cold Water Gas Pressure Washer with Honda GX390 Engine and CAT Triplex Pump on Stainless Steel Frame
The BE Power Equipment B4213HSJ is a commercial-grade cold water gas pressure washer delivering 4,200 PSI at 4.2 GPM, powered by a proven Honda GX390 389cc OHV engine and paired with a commercial-grade CAT 67DX39G1I P4 triplex pump with built-in unloader and fixed injector. Built on the 125S Stainless Steel Dealer Frame with 12" Ultra Premium flat-free tires and onboard accessory storage, the B4213HSJ is engineered for operators who need the long-term corrosion resistance of a stainless steel frame in demanding wet, outdoor, or chemical-exposure environments.
The 125S Stainless Steel Dealer Frame resists rust and corrosion more effectively than powder-coated steel over the long term, particularly in environments with regular water and chemical contact, coastal conditions, or high humidity. Whether you're cleaning concrete driveways, vinyl siding, agricultural equipment, trailers, or commercial building exteriors, the B4213HSJ gives you the power and durability to get the job done.
Built for Serious Outdoor Cleaning
The B4213HSJ is built to tackle demanding outdoor cleaning without slowing down. It is well suited for:
- Cleaning residential and commercial exteriors including siding, decks, driveways, fences, and walkways
- Vehicle, trailer, and equipment washing
- Farm and agricultural equipment cleaning
- Concrete and hard surface cleaning
- Construction site cleanup and surface preparation
Features
Honda GX390 Engine
The B4213HSJ is powered by the Honda GX390 389cc OHV recoil start engine, a commercial-grade engine known for reliability, consistent output, and long service life. Key engine features include:
- Reliable recoil start and smooth operation
- High-torque OHV design for consistent output
- Automatic low-oil shutdown to protect the engine from damage
- Fuel-efficient OHV design for extended runtime
- 6.1 L / 1.6 GAL fuel tank for extended operation between refueling
The Honda GX390 engine is covered under Honda's separate engine warranty program.
Commercial-Grade CAT P4 Triplex Pump with Built-In Unloader
Paired with the Honda engine is a commercial-grade CAT 67DX39G1I P4 class triplex pump with built-in unloader. CAT Pumps is a trusted commercial and industrial pump brand known for reliability in high-pressure cleaning applications. The triplex design delivers smooth, consistent pressure output and longer service life compared to axial pump configurations.
The built-in unloader regulates water flow and maintains consistent pressure when the trigger gun is released, protecting the pump during bypass operation. The pump includes a thermal relief valve that releases built-up heat if the unit is left running with the trigger closed for an extended period.
The B4213HSJ uses a fixed injector — detergent is drawn at a fixed rate when the soap nozzle is attached. Switch to the soap nozzle to apply detergent, then swap back to a pressure nozzle to rinse. Operators requiring adjustable detergent concentration should consider the B4213HSJS, which features an external unloader and adjustable injector.
125S Stainless Steel Dealer Frame
The B4213HSJ is built on the 125S Stainless Steel Dealer Frame, a hand-truck style platform constructed from stainless steel rather than powder-coated carbon steel. Stainless steel provides superior long-term corrosion resistance in environments with regular water exposure, chemical contact, coastal salt air, or high humidity — extending the service life of the frame where standard steel frames would corrode over time. The frame includes onboard accessory storage for the hose, wand, and nozzles, with stabilizing rubber feet for steady operation.
50-Foot x 3/8" Single Wire Braided High-Pressure Hose
The included 50' x 3/8" QC single wire braided rubber hose provides durability and extended reach for cleaning large areas without repositioning the machine. The 3/8" diameter supports the full 4.2 GPM flow rate of this unit.
36" Insulated Spray Wand and Trigger Gun
The included 36" QC insulated spray wand provides reach and control for high, low, and hard-to-reach cleaning angles. The insulated design reduces heat transfer to the operator during prolonged use, and the quick-connect system makes nozzle changes fast and straightforward.
4 Quick-Connect Spray Nozzles
Four quick-connect nozzles cover a full range of cleaning applications:
- 15°: Heavy-duty cleaning and surface stripping
- 25°: General-purpose washing
- 40°: Rinsing or cleaning delicate surfaces
- Soap: Low-pressure nozzle for applying detergent through the fixed injector
12" Ultra Premium Flat-Free Tires
The 12" Ultra Premium flat-free tires roll easily over gravel, dirt, and uneven terrain without requiring air inflation — no flats, no downtime.
Safety Features
- Automatic low-oil shutdown: Turns off the engine if oil drops below a safe operating level
- Thermal relief valve: Releases built-up heat from the pump when the unit is left running with the trigger closed
Warranty and Factory Testing
The B4213HSJ is backed by a 3-year limited warranty from BE Power Equipment. The Honda GX390 engine is covered separately under Honda's manufacturer warranty program.
Each unit is functionally tested at the factory before shipping. Your pressure washer may arrive with minimal residual oil or fuel odor, which confirms the unit has passed quality testing and is ready for use.

Frequently Asked Questions about Pressure Washers
How to store a pressure washer?
To ensure the durability of your heavy duty pressure washer:
- Empty the gas tank to prevent fuel from degrading or clogging the engine.
- Empty the pump and hoses of any remaining water.
- Perform necessary maintenance before storage.
- Store in a dry area.
- Cover.
What is a pressure washer?
A power washer is a cleaning machine that uses a gasoline engine to power a high pressure water pump and nozzle. It’s used to clean driveways, decks, vehicles, outdoor furniture and more by spraying water at high PSI to remove dirt, grime, mold and other debris.Many models also come with a detergent tank for added cleaning power.
How does a power washer work?
A power washer works by drawing water from a connected hose and pumping it through a high pressure nozzle. The gas engine powers the pump which pressurizes the water and then expels it through the nozzle at high speed to clean the surface. The water pressure is measured in PSI (pounds per square inch) and the flow rate is measured in GPM (gallons per minute).Many models also feature adjustable water pressure settings to cater to different cleaning needs. BE makes pressure washing easy with models available for light jobs and heavy duty commercial cleaning projects.
Gas vs Electric power washers?
The main difference is that a gas pressure washer, known for its cleaning power, is powered by a gasoline engine, making it more powerful and portable, while an electric pressure washer is powered by electricity and is generally quieter and lighter.
Gas pressure washers are for heavy duty and large areas due to their durability, whereas electric pressure washers are for smaller jobs.
Your BE electric pressure washer is perfect for smaller jobs and built for portability, and we offer a wide range of electric models. Included with our electric models is a long extension cord for use anywhere around your house.
What to consider?
When choosing a gas pressure washer consider:
- Pressure (PSI): More PSI means more cleaning power but also more potential for damaging delicate surfaces.
- Flow Rate (GPM): More GPM means faster cleaning as more water is dispensed.
- Engine Power: Bigger engines mean more durability and power.
- Portability: Weight, handle design and wheel size for easier to move.
- Nozzles: Multiple spray nozzles to adjust the spray pattern for different tasks.
- Adjustable Nozzle: Allows for fine-tuning the spray intensity and pattern for various cleaning needs.
How much pressure do I need for?
The required pressure (PSI) and cleaning power depend on the surface you’re cleaning:
- Light duty (car washing, outdoor furniture): 1,300-1,800 PSI.
- Medium duty (patios, fences, decks): 2,000-3,000 PSI.
- Heavy duty (driveways, brick walls, large equipment): 3,000+ PSI.
Many pressure washers come with adjustable pressure settings to handle different cleaning tasks effectively.
Can a pressure washing damage surfaces?
Yes, a power washer can damage surfaces if used incorrectly. High pressure water can strip paint, dent soft surfaces or even cause structural damage if the pressure is too high or the nozzle is held too close to the surface. Always use the right PSI for the material you’re cleaning and keep a safe distance from delicate surfaces.
To prevent damage, consider using a model with adjustable pressure settings.
How to maintain your pressure washer?
To ensure the durability and smooth operation of a pressure washer:
- Change the oil as per manufacturer’s instructions.
- Clean or replace the air filter to ensure good airflow.
- Inspect and clean the nozzle regularly to prevent clogs.
- Drain the gas tank if you’re storing the washer for a long time.
- Check the hoses for leaks or damage and replace them if needed.
- Follow regular maintenance requirements to keep the washer in optimal condition.
Can I use a pressure washer in cold weather and low water temperature?
You can use a pressure washer in cold weather but it’s more difficult. The water flow rate in the hoses and pump can freeze and damage the equipment. If you plan to use your pressure washer in cold temperatures make sure to winterize it and store it in a warm area when not in use. You can also use anti-freeze solutions for pressure washers.
Some models are designed to use hot water, which can be particularly effective for cleaning in cold weather.
Do I need any accessories?
Common accessories for power washers:
- Different nozzles (0°, 15°, 25°, 40°, and soap nozzle) to adjust spray patterns.
- Extension wands for hard to reach areas.
- Surface cleaners for large flat areas like driveways and decks.
- Hose reels to store hoses neatly and prevent tangling.
- Foam cannon or detergent bottles for soap or cleaning solutions.
- Detergents for cleaning a wide variety of surfaces.
