expand. Keep a space at the top of the fuel tank.

not tightened, there is a risk of fire.
• Before you start the product, move the product to a
minimum of 3 m/10 ft from where you refueled.
• Do not start the product if there is fuel or engine oil on
the product. Remove the unwanted fuel and engine oil
and let the product dry before you start the engine.

leaks in the fuel system, do not start the engine until
the leaks are repaired.

leaks.
