The Kärcher LFT Cage 4.0/40 Ge Pressure Washer is a professional hot-water pressure washer designed for demanding commercial and industrial cleaning applications. Delivering 4,000 PSI (276 bar) at 4.0 GPM (15.1 L/min), it combines a direct-drive crankcase pump, downdraft diesel burner system, electric start, flat-free tires, and a low-center-of-mass frame to provide powerful cleaning performance with improved maneuverability and easier service access.

KEY FEATURES

4,000 PSI HOT-WATER CLEANING POWER: The LFT Cage delivers 4,000 PSI (276 bar) at 4.0 GPM (15.1 L/min) for demanding commercial cleaning. This combination of pressure, water flow, and heated cleaning performance helps remove grease, oil, grime, and other difficult buildup more efficiently.
DOWNDRAFT DIESEL BURNER SYSTEM: The downdraft forced-air diesel burner is designed for efficient heating and lower emissions. With an output of 274,300 BTU/hr, it adds strong thermal cleaning capability for applications where cold water alone may not be sufficient.
PATENTED LOW-CENTER-OF-MASS FRAME: The rugged powder-coated steel frame uses a low-center-of-mass design to improve stability and maneuverability. This makes the machine easier to move and position around demanding worksites.
STAINLESS STEEL COIL SKIN: A durable stainless steel coil skin helps protect the heating system against demanding operating conditions. This construction supports long-lasting performance and reliability in professional hot-water cleaning applications.
REDUCED VIBRATION DESIGN: The engine and pump are isolated from the frame to help reduce vibration during operation. This can improve overall machine stability and contribute to a smoother operating experience.
FLAT-FREE TIRES: Flat-free tires provide dependable mobility without the downtime associated with punctured pneumatic tires. They are especially useful on rough jobsites where nails, sharp debris, or uneven surfaces may be present.
9-GALLON DIESEL TANK: The integrated 9 gal. (34.1 L) diesel tank supports longer operating periods between fuel refills. This helps reduce interruptions during extended hot-water cleaning jobs.
QUICK-RELEASE CONTROL PANEL: The quick-release control panel provides easier access to internal components for inspection and maintenance. Combined with the machine's open-service design, this helps simplify routine upkeep and reduce service effort.
50 FT. HIGH-PRESSURE HOSE: The included 50 ft. (15.2 m) high-pressure hose provides practical reach around vehicles, equipment, and work areas. Quick-connect fittings help speed up setup and hose attachment.
48 IN. SPRAY LANCE: The included 48 in. (121.9 cm) spray lance gives operators additional reach while maintaining control of the cleaning stream. This helps make cleaning large equipment and hard-to-reach areas more convenient.
ADJUSTABLE THERMOSTAT: The adjustable thermostat allows operators to control water temperature according to the cleaning task. This provides flexibility when moving between lighter cleaning and more demanding grease or oil removal.
HOUR METER: An integrated hour meter helps track machine usage for maintenance planning and service intervals. This makes it easier for professional operators to manage preventive maintenance based on actual operating time.
DOWNSTREAM CHEMICAL INJECTION: The downstream chemical injection system allows compatible detergents and cleaning agents to be applied when additional cleaning action is needed. This provides greater flexibility for tackling stubborn soils.
FOUR QUICK-CONNECT NOZZLES: Four quick-connect nozzles provide multiple spray patterns for different cleaning requirements. Operators can quickly change nozzle configurations to suit the surface, soil level, and desired spray coverage.

APPLICATIONS / USE CASES

HEAVY EQUIPMENT CLEANING: High pressure and heated water make the LFT Cage well suited for removing grease, oil, dirt, and buildup from construction machinery and industrial equipment. The durable cage frame and flat-free tires support use in demanding work environments.
FLEET AND VEHICLE WASHING: The 4,000 PSI (276 bar) output and 4.0 GPM (15.1 L/min) flow rate provide strong performance for trucks, trailers, service vehicles, and fleet equipment. Heated water can help break down oily road film and heavy grime more effectively.
INDUSTRIAL FACILITY CLEANING: Suitable for cleaning work areas, machinery, exterior surfaces, and production equipment in commercial and industrial settings. The adjustable thermostat lets operators tailor heat output to different cleaning requirements.
CONSTRUCTION SITE CLEANING: The low-center-of-mass design, rugged frame, and flat-free tires make the machine practical for construction and contractor environments. It can be moved across rough surfaces while delivering professional hot-water cleaning performance.
GREASE AND OIL REMOVAL: Heated water and downstream detergent injection work together to tackle greasy and oily contamination. This makes the unit useful for maintenance operations, equipment service areas, and other demanding wash applications.
