Tool Cleaning Process
Regular cleaning will increase the life span of the machine. Clean the machine after each use.
Check before cleaning that the fuel tank cap is properly in place to avoid getting water in the tank.
Use care when using a high-pressure washer because it can damage decals, grease seals, and the engine.
