Cleaning
Cleaning the Machine
Regular cleaning and washing with mild detergent and
water increases the life span of the machine. Clean
the machine after each use before the dirt hardens.
Remove dirt and grime from the external parts of the
entire machine, especially the engine. Clean dirt and
concrete materials from the outside of the engine.
Ensure that the fuel cap and the oil-fill cap/dipstick are
secure to avoid getting water in the engine.
Use care when using a high-pressure sprayer
because it can damage the safety decals, instruction
signs, and the engine.
Important:
Lubricate the bearings and seals after
cleaning; refer to
Lubricating the Bearings and
Seals (page
29).
