4.2 Fuel and Oil

The engine is shipped without oil or fuel. You must add both before starting the unit.

• Add Engine Oil: Remove the oil fill cap/dipstick. Add the recommended engine oil (refer to engine manual for type and capacity) until it reaches the full mark on the dipstick. Do not overfill.
• Add Gasoline: Fill the fuel tank with fresh, unleaded gasoline (minimum 87 octane). Do not overfill. Leave space for fuel expansion.

4.3 Water Connection

• Connect a garden hose (minimum 5/8 inch diameter) to the water inlet on the pressure washer.
• Ensure the garden hose is free of kinks and has a steady water supply.
• Turn on the water supply completely.
• Squeeze the trigger on the spray gun to purge air from the pump and hose until a steady stream of water emerges. This prevents damage to the pump.
