The innovative, rugged design of the Kärcher Classic HDS LP-heated cabinet pressure washer delivers up to 3.9 GPM at 3,000 PSI of industrial power. Constructed with anodized structural rivets, a water cooled electric motor, standard auto start/stop and Kärcher’s axial direct-drive pump backed by a 7-year warranty. Six lift out panels and easy lock fasteners provide easy access to components for maintenance in tight spaces. The extra-durable heating coil is made of leak-free, cold-rolled, Schedule 80 steel pipe and is wrapped with a thick foil blanket insulation that keeps cabinet walls cool to the touch. Standard electronic ignition eliminates the hassle of having to monitor and light a pilot flame.The pulsation damper reduces vibrations on the high pressure side of the system. An integrated RM 110 reservoir protects the machine from scale build-up in the heating coil. The 41" rotating lance and ergonomic Kärcher Easy Press trigger gun provide ultimate control and comfort, and Kärcher Power Nozzles deliver 40% more cleaning power compared to similar models. All models are ETL certified to UL and CSA safety standards.
