+1 (978) 295-7538CA-3504-1MAK Gas Pressure Washer — CA Aluminum Series 3500 PSI with Kohler CH440
The CA-3504-1MAK produces 3500 PSI at 3.5 GPM — 12,250 cleaning units — from a 429cc Kohler CH440 OHV engine paired with an AR crankshaft pump on Mi-T-M's 125-lb aluminum frame. The CH440 is Kohler's largest single-cylinder commercial engine, providing the displacement reserve needed to maintain rated 3500 PSI / 3.5 GPM output under sustained load in hot ambient conditions. All three CA-3504 standard variants — Honda GX390 (1MAH), Kohler CH440 (1MAK), Mi-T-M OHV (1MAM) — produce the same output from the same frame. The 1MAK is the choice for operations with established Kohler dealer relationships or with the CH440 already in their equipment fleet. ETL listed for US commercial use.
CA-3504-1MAK Engine Specifications and Aluminum Frame
The Kohler CH440 displaces 429cc — notably larger than the Honda GX390's 389cc — which provides additional torque reserve at the high end of the pressure range. At 12,250 CU the CA-3504 handles work that overtaxes the CA-3003: removing heavy equipment fouling in single passes, stripping loose coatings from masonry, and washing large commercial vehicle fleets efficiently. The 125-lb aluminum frame with 13-in flat-free tires handles rough job-site terrain that can stop smaller-wheeled units.
- 3500 PSI at 3.5 GPM (12,250 CU) — 36% more cleaning power than the CA-3003; single-pass effectiveness on heavy equipment fouling
- 429cc Kohler CH440 OHV engine — Kohler's largest single-cylinder commercial engine; cast-iron liner, full-pressure lubrication; Kohler commercial warranty
- AR crankshaft pump, forged brass manifold, thermal relief valve — AR rated for sustained 3500 PSI; brass handles mineral-rich water; thermal valve protects pump seals
- 125-lb corrosion-resistant aluminum frame, 13-in flat-free tires — lighter than steel-frame equivalents; larger tires handle rough terrain better than the 10-in tires on lower CA models
- ETL listed, patented vibration isolation plate — ETL certification for commercial procurement; vibration plate extends pump seal life
- 50-ft × 3/8-in hose, 48-in lance — 48-in reach for elevated surfaces and equipment; CX-0098 External Bypass available separately
CA-3504-1MAK Applications and Environments
Operations running Kohler-powered generators, line stripers, or floor sweepers add the CA-3504-1MAK to standardize their CH440 parts shelf across equipment categories. Fleet maintenance departments that service vehicles with heavy road salt deposits, mud, and industrial coating residue rely on the 12,250 CU output for single-shift completion of washing cycles. Construction firms use it for concrete form stripping and equipment prep. Agricultural operations apply it to post-harvest equipment cleaning where caked grain, silage, and fertilizer residue require sustained high-pressure output. Industrial plants use it for machinery washdown between production cycles.
