Mi-T-M CA-4004-1MGH — Aluminum-Frame Direct Drive at 4000 PSI, 4.0 GPM

The CA-4004-1MGH puts 4,000 PSI and 4.0 GPM through a General pump driven directly by a 389cc Honda GX390 OHV engine. The aluminum frame cuts 30–40 lbs. versus steel-chassis competitors at the same output class, while the patented vibration isolation plate keeps pumps and fasteners tight through full-shift operation.

CA-4004-1MGH Engine, Pump, and Frame System

  • 389cc Honda GX390 OHV engine — industrial-grade cast-iron bore, 270-hour oil-change interval, electric or recoil start.
  • General pump with Mi-T-M Pressure Relief Start — pressure drops to near-zero before the starter engages, eliminating kickback and reducing pull cord wear.
  • External bypass system and thermal relief valve — recirculates water when trigger is released, preventing heat buildup that destroys pump seals.
  • Forged brass manifold and clear-sleeve water filter — corrosion-proof manifold handles 4,000 PSI continuous; filter is inspectable without tools.
  • Corrosion-resistant aluminum frame with patented vibration isolation plate — 125-lb unit rolls on 13-inch flat-free tires across gravel, asphalt, and mud.

Commercial and Industrial Cleaning Applications

Cleaning contractors use the CA-4004-1MGH on concrete, masonry, and painted metal where 4,000 PSI cuts through years of oil, carbon, and biological buildup in a single pass. Fleet maintenance operations rely on the Honda GX390's proven service interval to run the unit across an eight-vehicle wash cycle without mid-job maintenance stops. Construction cleanup crews favor the aluminum frame's weight advantage when loading and unloading from work trucks multiple times a day. Agricultural operations wash harvested equipment and livestock facilities where the 4.0 GPM flow rate reduces total water time per structure. ETL certified for the US market; 49-state engine — not for sale in California without CARB-compliant substitution, consult factory.

Frequently Asked Questions

What PSI and GPM does the Mi-T-M CA-4004-1MGH deliver?
The CA-4004-1MGH produces 4,000 PSI at 4.0 GPM, giving it a cleaning units (CU) rating of 16,000 — in the upper tier of cold-water gasoline direct-drive machines in this weight class.
What engine powers the CA-4004-1MGH?
A 389cc Honda GX390 OHV engine with a cast-iron bore sleeve. Honda rates the GX390 for commercial-duty use with oil change intervals at approximately 100 hours under normal conditions.
What is Mi-T-M's Pressure Relief Start and why does it matter?
Pressure Relief Start drops system pressure to near-zero before the starter engages, so the engine turns over freely without fighting a pressurized pump. This eliminates the hard-pull kickback common on high-PSI units and reduces recoil starter wear.
Does the CA-4004-1MGH have a bypass system to protect the pump?
Yes. The General pump includes an external bypass system that recirculates water back to the inlet when the trigger is released. This prevents heat buildup in the pump head — the leading cause of seal failure on direct-drive machines operated in stop-and-start patterns.
Is the CA-4004-1MGH available for sale in California?
No. The CA-4004-1MGH is equipped with a 49-state engine that does not meet California Air Resources Board (CARB) emissions standards. Buyers in California should contact the factory for the CARB-compliant version.
What nozzles and accessories are included?
The CA-4004-1MGH includes three quick-connect nozzles (0°, 15°, 25°), a 50-ft non-marking hose, a 48-inch lance, and an insulated trigger gun. A 40° rinse nozzle is not included with this model.
How much does the CA-4004-1MGH weigh and how is it transported on a job site?
The unit weighs 125 lbs. and rolls on 13-inch flat-free pneumatic-style tires that never go flat. One operator can maneuver it across gravel, concrete, and compacted soil without lifting.
