• EASY!LOCK QUICK-RELEASE CONNECTIONS: EASY!Lock couplings allow compatible hoses, lances, and accessories to be connected quickly and securely. Kärcher describes these connections as up to five times faster than conventional threaded screw connections, helping reduce setup and accessory changeover time.
• FINE-MESH WATER FILTER: The integrated fine-mesh filter helps protect the high-pressure pump from contamination entering through the water supply. This supports reliable machine operation and helps reduce the risk of damage caused by debris in the incoming water.
• INTEGRATED DETERGENT INJECTOR: The built-in detergent injector allows compatible cleaning solutions to be introduced during appropriate cleaning procedures. This helps operators tackle heavily soiled surfaces without relying entirely on water pressure.
• FLUE GAS TEMPERATURE MONITOR: The machine includes a flue gas temperature monitoring feature associated with its hot water heating system. This supports monitoring of the heating process and helps protect the equipment during operation.
• ADJUSTABLE PUSH HANDLES: Adjustable handles help operators position the machine for comfortable movement and transportation. This improves handling convenience when moving between work areas or loading the unit for transport.
• EASY-TO-FILL TANKS: The machine is designed with accessible filling points for its operating fluids. This helps simplify preparation and reduce interruptions when replenishing fuel or compatible cleaning supplies.
• 1.72 US GAL (6.5 L) FUEL TANK: The integrated fuel tank holds approximately 1.72 US gal (6.5 L) for the hot water heating system. This provides onboard fuel storage while maintaining the machine's compact and portable design.
• 33 FT (10 M) HIGH-PRESSURE HOSE: The included high-pressure hose provides approximately 33 ft (10 m) of working reach. This allows operators to clean around vehicles, equipment, and other obstacles without frequently repositioning the pressure washer.
• 33.1 IN (84 CM) SPRAY LANCE: The supplied spray lance measures approximately 33.1 in (84 cm). Its extended reach helps operators maintain a practical working distance from the cleaning surface and access areas that are difficult to reach directly.
• INTEGRATED ACCESSORY STORAGE: The upright housing includes a spray lance holding clip, power cord storage, nozzle compartment, and accessory storage locations. These features keep essential components organized and reduce the chance of misplacing tools during transport.
• CONVENIENT TANK LOCK: The integrated tank lock helps secure the machine's tank arrangement during handling and transport. This supports the practical mobility features of the upright pressure washer design.
• STEP TROUGH FOR TIPPING: A dedicated step trough provides a convenient point for tilting the machine onto its transport wheels. This helps operators maneuver the unit with greater control when moving between cleaning locations.
• 120 V SINGLE-PHASE ELECTRICAL SYSTEM: The machine operates on a listed 120 V, 60 Hz, single-phase electrical supply with a connected load of 1.7 kW. This electrical configuration supports professional cleaning applications where a suitable power connection is available.
• VERSATILE OPTIONAL ACCESSORIES: Compatible accessories include specialty spray nozzles, surface cleaners, washing brushes, gutter cleaning tools, and wet blasting attachments. These options allow operators to adapt the machine for different cleaning applications without replacing the entire pressure washing system.
