Power washing is the easiest way to clean your professional lawn equipment. Please be careful, as some components can be damaged during power washing. Please follow these guidelines:
Transmissions, transaxles and differentials contain grease and the seals are not watertight. Water under pressure will penetrate the case seams allowing water into the internal workings and possibly causing premature failure. Do not direct the spray directly towards the transmission, transaxle or differential of your outdoor lawn equipment.
Bearings and bushings should not be sprayed directly with water. If they are accidentally sprayed, make sure they are greased or re-lubricated to prevent seizing or premature failure.
Avoid water contacting the clutch-brake of your outdoor lawn equipment if at all possible. Water getting inside of the clutch brake will cause it to rust, which will cause increased friction and heat, resulting in reduced life of the clutch.
If lubricant is washed off of the drive chains, they must be re-lubed before using. Running chains dry or without lubrication will cause premature failure of the chain and the drive sprockets.
Engines: While engines for the most part are sealed, there are certain components that should not be sprayed directly with a power washer. Keep water away from the air cleaner, muffler, recoil start, fuel tank cap area and electrical components. Never wash an engine when hot, the sudden temperature change could be damaging to the engine block, exhaust and electrical components.
