Air cooled engines run hotter than automotive engines. The use of multi-viscosity oil such as (10W-30, etc.) in ambient temperatures above 40°F (4°C) will result in higher than normal oil consumption, if multi-viscosity oil is used, check the oil level more frequently to prevent any posssibie engine damage due to lack or lubrication. Use of SAE30 oi! below 40°F (4°C) will result in hard starting and possible engine damage due to inad equate iubrication.

Gasoline

Your pressure washer engine is 4 cycie. Use unleaded fuel only.

A CAUTION; Do not overfill the fue! tank. Always

allow room for fuel expansion.

A WARNING; Never fill fuel tank indoors. Never

fill fuel tank when engine is running or hot. Do not smoke or have open flame when filling fuel

tank.

Use clean, fresh, regular unleaded gasoline with a minimum of 85 octane. Do not mix oil with gasoline. If unleaded fuel is not available, leaded fuel may be used.

IMPORTANT: It is important to prevent gum deposits

from forming in essential fuel system parts such as the carburetor, fuel filter hose or tank during storage. Also,

experience indicates that alcohol-blended fuels (called gasohol or using ethanol or methanol) can attract mois ture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may

occur. NOTE: Never start pressure washer with out water

source turned on and connected to pressure washer.
