Preparation

Fuel

1. Stop the engine. 2. Place the multi-purpose engine on a level surface.

3. Remove the fuel tank cap.

4. Check the fuel level. 5. If low, fill the tank with fuel. Do not fill past the bot-

tom of the fuel filler as fuel may mix with the acti- vated charcoal in the fuel tank cap and overflow.

TIP If filled beyond the bottom of the fuel filler, fuel may mix with the active charcoal located within the fuel tank cap and soil the surrounding areas.

Fuel is highly flammable and poisonous. Check Safety information (See page 1) care- fully before filling.

Carefully fill the fuel tank in order to avoid fuel from spilling out of the fuel tank.

Stop filling when the fuel reaches the bottom of the fuel filler, otherwise it may overflow when the fuel warms up and expands.

Wipe up any spilled fuel immediately. After filling the tank with fuel, make sure the fuel

tank cap is tightened securely.
