Features

Honda GX390 Engine

At the heart of this pressure washer is the Honda GX390 389cc recoil start engine, a commercial-grade overhead valve engine known for durability, consistent output, and long service life. Key engine features include:

  • Reliable recoil start and smooth operation
  • High output for tough cleaning applications
  • Automatic low-oil shutdown to protect the engine
  • 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 CP CTG2S Triplex Pump

Paired with the Honda engine is a commercial-grade CP CTG2S P4+ triplex pump with external unloader and adjustable injector. The triplex design delivers smoother pressure output and longer service life than axial pump configurations, making the B4213HAS well suited for regular and demanding commercial use. Key pump features include:

  • P4+ commercial pump class for high-frequency, high-pressure cleaning applications
  • Thermal relief valve to prevent pump damage during extended idle periods
  • Smooth, consistent pressure delivery at 4,200 PSI

External Unloader with Adjustable Injector

The external unloader effectively regulates water flow and pressure when the trigger gun is released, keeping the pump cool during bypass operation and extending the life of critical components. The adjustable injector allows you to dial in detergent concentration to match different surfaces and cleaning products, giving you greater flexibility than a fixed injector configuration.

125 Dealer Frame with Powder-Coated Steel Construction

The B4213HAS is built on the 125 Dealer Frame, a proven hand-truck style platform with powder-coated steel construction designed for rugged commercial use. The frame includes onboard accessory storage for the hose, wand, and nozzles, keeping everything organized and accessible throughout the workday. Stabilizing feet keep the unit stable during operation.

50-Foot x 3/8" Steel 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

A 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 are included to 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: Applying detergents and degreasers through the adjustable injector

12" Ultra Premium Flat-Free Tires

No flats, no downtime. The 12" Ultra Premium flat-free tires roll easily over gravel, dirt, and uneven terrain without requiring air inflation, improving portability and stability across all job sites.

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 during extended idle periods

Warranty and Factory Testing

The B4213HAS 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.
