Add Engine Oil

IMPORTANT: Any attempt to crank or start the engine

before it has been properly serviced with the recommended oil may result in an engine failure.

NOTE: When adding oil to the engine crankcase, use only high quality detergent oil rated with API service classification SF, SG, SH, SJ or higher rated SAE 30 weight. DO NOT use special additives.

1. Choose a viscosity according to table below.

* The use of multi-viscosity oils (5W-30, 10W-30, etc.)

in temperatures above 40°F (4°C) will result in higher than normal oil consumption. When using a multiviscosity oil, check oil more frequently.

** If using SAE 30 oil in temperatures below 40°F

(4°C), it will result in hard starting and possible engine bore damage due to inadequate lubrication.

2. Place pressure washer on a level surface.

3. Clean area around oil fill.

4. Remove oil fill cap.

5. Pour oil slowly. Fill to the point of overflowing.

6. Replace oil fill cap, tighten securely.

NOTE: Check oil often during engine break–in.

Add Fuel

WARNING! NEVER fill fuel tank indoors.

NEVER fill fuel tank when engine is running or hot. Allow unit to cool for two minutes before refueling. DO NOT light a cigarette or smoke when filling the fuel tank.

WARNING! NEVER fill fuel tank completely

full. Provide space for fuel expansion. Wipe away any fuel spillage from engine and equipment before starting.

• Use fresh, clean unleaded automotive fuel and

store in approved, clean, covered containers. Use clean fill funnels. NEVER use “stale” fuel left over from last season or fuel stored for long periods.

• Clean area around fuel fill cap, remove cap.

• Slowly add fuel to fuel tank. Use a funnel to

prevent spillage. Fill tank to about 1.5” below top of the filler neck.

• Install fuel cap and wipe up any spilled fuel.

IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts, such as the carburetor, fuel filter, fuel hose or tank during storage. Also, experience indicates that alcohol–blended fuels (called gasohol, ethanol or methanol) can attract moisture, 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. See “Storage” on pages 16-17. NEVER use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.
