Description
The Mi-T-M ChoreMaster CM-4200-0MMB is rated at 4,200 PSI and 3.4 GPM, or 14,280 cleaning units, with a 420cc Mi-T-M OHV engine and a Mi-T-M crankshaft pump. A 50 ft wire-braided hose is included.
Highlights

- Mi-T-M triplex crankshaft pump: brass manifold, thermal relief valve and in-line water strainer.
- Mi-T-M Pressure Relief Start: reduces compression during pull starting for easier cold starts.
- Adjustable pressure unloader: turn pressure down for vehicles and painted surfaces without changing nozzles.
- 10 in flat-free tires: stable on gravel lots, construction debris and loading docks.
