+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 1MAK is the choice for operations with established Kohler dealer relationships or with the CH440 already in their equipment fleet.
CA-3504-1MAK Engine Specifications and Aluminum Frame
The 125-lb aluminum frame with 13-in flat-free tires handles rough job-site terrain that can stop smaller-wheeled units.
- 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
- 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.
