Fueling
Pay attention to the fire. Please keep the fuel tank far away from the flame or sparks. Don’t smoke near fuel. When the machinery is running, ban adding fuel to the fuel tank.
Open the fuel cap carefully to allow any pressure build-up in the tank release slowly and avoid fuel spillage. Fuel your power tool only in wellventilated areas. If you spill fuel, wipe the machine immediately – if fuel gets on your clothing, change immediately.

Do not direct the air blast towards bystanders since the air flow can blow small objects at great speed.

Your power tool produces toxic

exhaust fumes as soon as the

engine is running. These fumes
