.
GASOLINE FIRES AND HANDLING FUEL SAFELY
Fuels and their vapors are flammable and highly volatile!
Fuel fires can spread quickly and even can be explosive!
Never use fuel when a spark or flame may be present.
Never use fuel where a potential source of ignition could occur. (Examples include: hot water heaters or space heaters, clothes dryer, electric motors, etc). Keep flames and sparks away from engine and fuel at all times to prevent fires.
PREVENTION OF GASOLINE FIRES
Never fill your fuel tank with fuel inside a building including a basement, garage, barn, shed, house, porch, etc.
Always fill fuel tank outside in a well ventilated area.
Stop any engine and allow cooling before refilling tank.
Never remove the fuel cap or add fuel while the engine is running.
Never drain fuel from engine in an enclosed area.
Always wipe up excess (spilled) fuel from engine before starting. Clean up spilled fuel immediately.
Allow spilled fuel to dry, after wiping and before starting
Always allow fuel fumes/vapors to escape from the area before starting engine.
Test the fuel cap for proper installation and tightness before starting and using engine.
Always run the engine with fuel cap properly installed on the engine and gas cap vent screw unscrewed.
Replace any fuel cap that allows gas to spill or leak.
Never smoke near any fumes/vapor or while refilling engine fuel tank.
Do not store unit with fuel in the fuel tank in a confined space. Fuel and fuel vapors are highly explosive.
Always check that gas cap vent screw is tightly secured.
Never pour fuel from engine fuel tank.
Never siphon fuel by mouth to drain fuel tank.
Always have an adult fill the fuel tank.
Never allow an adult or anyone under the influence of drugs or alcohol to fill engine.
Never allow children to fill the engine or operate this unit.
CAUTION
TAKE GREAT CAUTION WITH MUFFLER, MUFFLER
GUARD & OTHER PARTS OF ENGINE AS THEY
BECOME EXTREMELY HOT DURING OPERATION.
THESE PARTS REMAIN EXTREMELY HOT EVEN
AFTER ENGINE HAS STOPPED.
PREVENTION OF BURNS AND FIRES
Never remove the muffler guard from the engine.
Never touch the muffler guard because it is extremely hot and will cause severe burns.
Never touch parts of the engine that become hot after operation.
Always keep materials and debris away from muffler guard and other hot parts of the engine to avoid fires.
This engine is designed to operate using a catalytic converter which contributes to the engine’s compliance with the EPA.
WARNING CARBON MONOXIDE POISONING
Fuel driven engines contain carbon monoxide in their exhaust. Even if you do not see or smell carbon monoxide; the deadly, colorless, tasteless, odorless gas may be present in the exhaust. Any enclosed areas of poor ventilation can potentially house deadly levels of carbon monoxide for days. If inhaled, any level of carbon monoxide can cause headaches, drowsiness, nausea, dizziness, confusion and eventually death. If
you experience any of these symptoms, seek fresh
air and medical attention immediately.
PREVENTING CARBON MONOXIDE POISONING
Never run the engine indoors.
Carbon monoxide can reach dangerous levels very quickly. Never try to ventilate engine exhaust indoors.
Never run engine outdoors where exhaust fumes may be pulled into a building.
Exhaust fumes are trapped easily and may not disperse. Never run engine outdoors in a poorly ventilated area (Examples include: hilly terrain, thickets or a large hole you are working in.)
Never run engine in an enclosed or partially enclosed area such as: tents, open garages, car ports, buildings that are enclosed on one or more sides, or basements.
Always point the exhaust and muffler away from the operator.
