Basics
- A Hot Water Pressure Washer that runs off a Gasoline Engine (A Honda GX390 to be specific) and a Diesel Burner (A Wayne MSR DC-12V Burner )
- Also has a certain degree of Foolproofing features, although once “on the fritz” they can become a bit of a hindrance
- It HAS wheels, but short of going in straight lines/lifting the front wheels to turn it, it isn’t VERY mobile
- Also the brake stabs INTO THE WHEELS, so not a great design there. Something akin to a ratchet mechanism, but a shape welded onto the axle would be nicer
- Quite loud too, but especially for Mobile Unit, better mufflers/a hush box (re Generator Shed etc) are hard to do
- A Motorcycle Muffler / Small Engine Muffler (assuming it doesn’t impact engine performance etc) would be nicer however
Quick Reference
Specs
- Pressure (psi) 2400
- Flow rate (gal/min) 2.7
Fuel
- Gasoline (Preferably Ethanol Free Gasoline , although E-10 / E-15 MAY RUN short term, just don’t store it like that)
- Diesel / Off Road Diesel
- Uncertain on if Home Heating Oil / Kerosene / Marine Diesel Oil etc will run in it
Lubricating Oil
- Engine Oil: 10W-30
- As per This Manual 10W-30 is recommended, although in some temperature regimes, 20W-50 , 20W-50 , and 10W-40 are permissible/recommended
- Pump Oil: “ SAE 10W-40 Non-Foaming “
Circuit Breaker
- In is Off
- Out is when it needs reset
Sourcing
- ~5k USD New
Internal Links
- Hot Water Pressure Washer
- Propane Hot Water Pressure Washer
- Short of SLIGHTLY more difficult fuel sourcing, this would eliminate much of the issues with the Gas/Diesel system
- Propane Hot Water Pressure Washer
External Links
- The Official Landa Page on the MHC Line
- The Operator’s Manual for the Landa MHC
- ”Use heating oil or diesel. If diesel is used, it is recommended to add a soot remover to every tankful to reduce soot build up on the heating coil. 10. Use No. 1 or No. 2 heating oil ( ASTM D306 ) only. NEVER use gasoline in your fuel oil tank. Gasoline is more combustible than fuel oil and could result in a serious explosion. NEVER use crankcase or waste oil in your burner. Fuel unit malfunction could result from contamination”
- ASTM Standard is Wrong, D306 is for Aluminum Powder Specs, D396 is the correct standard, re ASTM D396
