Mi-T-M CA-4004-1MGM — 4000 PSI Direct Drive with Mi-T-M OHV Engine

The CA-4004-1MGM delivers 4,000 PSI at 4.0 GPM through the same corrosion-resistant aluminum platform as the Honda-powered CA-series, powered instead by a 420cc Mi-T-M OHV engine — Mi-T-M's proprietary engine built to the same commercial specification at a lower acquisition cost. General pump, patented vibration isolation plate, and 13-inch flat-free tires are standard across both engine configurations.

CA-4004-1MGM Engine, Pump, and Aluminum Frame

  • 420cc Mi-T-M OHV engine — Mi-T-M proprietary commercial-duty engine; same displacement class as Honda GX420, designed for continuous-use cleaning cycles.
  • General pump with Mi-T-M Pressure Relief Start — low-resistance start engagement prevents kickback on 4,000 PSI systems.
  • Forged brass manifold and thermal relief valve — thermal relief discharges water if pump temperature exceeds safe threshold during extended bypass periods.
  • Corrosion-resistant aluminum frame — lighter than steel-frame competitors; patented vibration isolation plate extends bolt and seal life.
  • 13-inch flat-free tires — move the 125-lb unit without puncture risk on job sites with nails, glass, and debris.

Contractor and Maintenance Cleaning Deployment

The CA-4004-1MGM occupies the same performance tier as the Honda-powered CA-4004-1MGH but reduces total cost of ownership for fleets where engine serviceability through a broad distribution network matters less than upfront price. Facility maintenance contractors running multiple units split their fleet between Honda and Mi-T-M OHV variants to balance parts-availability risk. Construction and fleet cleaning operations where the unit runs 4–6 hours per day benefit from the thermal relief valve and bypass system that prevent the pump failures common in budget direct-drive machines lacking those protections. ETL certified; 49-state engine — not for sale in California.

Frequently Asked Questions

What is the difference between the CA-4004-1MGH and CA-4004-1MGM?
Both deliver 4,000 PSI at 4.0 GPM with the same aluminum frame, General pump, and accessory package. The 1MGH uses a 389cc Honda GX390 engine; the 1MGM uses a 420cc Mi-T-M OHV engine. The Mi-T-M engine is Mi-T-M's proprietary commercial-duty unit at a lower list price.
What engine is in the CA-4004-1MGM and what is its displacement?
The CA-4004-1MGM uses a 420cc Mi-T-M OHV (overhead valve) engine — Mi-T-M's proprietary commercial engine rated for continuous cleaning-duty cycles.
Does the CA-4004-1MGM have pump protection during bypass?
Yes. The General pump is equipped with a thermal relief valve that discharges water to prevent heat buildup when the trigger is held closed for extended periods, protecting pump seals from thermal damage.
Is the CA-4004-1MGM ETL certified?
Yes, the CA-4004-1MGM carries ETL certification for the US market, confirming it meets applicable safety standards for commercial pressure washing equipment.
Can the CA-4004-1MGM be sold in California?
No. The 420cc Mi-T-M OHV engine in the CA-4004-1MGM is a 49-state configuration and does not meet California Air Resources Board (CARB) emissions regulations. Contact the factory for a CARB-compliant alternative.
What nozzles are included with the CA-4004-1MGM?
Three quick-connect nozzles are included: 0° (pinpoint), 15° (heavy strip), and 25° (general cleaning). A 40° rinse nozzle is not included with this model. The 50-ft hose, 48-inch lance, and insulated trigger gun are also included.
How does the aluminum frame affect weight versus steel-frame pressure washers?
The corrosion-resistant aluminum frame keeps the CA-4004-1MGM at 125 lbs. net weight. Comparable steel-frame machines in the 4,000 PSI class typically weigh 150–180 lbs., making the aluminum CA-series significantly easier to load, unload, and reposition on job sites.
