PRE-OPERATION CHECK
Refuel in a well-ventilated area before starting the engine. If the engine has been running, allow it to cool.
Refuel carefully to avoid spilling fuel. DO NOT fill the fuel tank completely.
Fill tank to approximately 1 inch (25 mm) below the top of the fuel tank to allow for fuel expansion. It may be
necessary to lower the fuel level depending on operating conditions.
After refuelling, tighten the fuel tank cap securely.
NEVER refuel the engine inside a building where petrol fumes may reach flames or sparks.
Keep petrol away from pilot lights, barbecues, electric appliances, power tools, etc.
Spilled fuel is not only a fire hazard, it causes environmental damage. Wipe up spills immediately.
Fuel can damage paint and plastic. Be careful not to spill fuel when filling your fuel tank.
Damage caused by spilled fuel is not covered under warranty.
Fuel Recommendations
Use unleaded petrol with an octane rating of 95 or higher.
These engines are certified to operate on unleaded petrol. Unleaded petrol produces fewer engine and spark
plug deposits and extends the exhaust system life.
NEVER use stale or contaminated fuel or an oil/fuel mixture. Avoid getting dirt or water in the fuel tank.
Occasionally you may hear a light “spark knock” or “pinging” (metallic rapping noise) while operating under
heavy loads. This is no cause for concern.
If spark knock or pinging occurs at a steady engine speed, under normal load, change brands of petrol.
Running the engine with persistent spark knock or pinging can cause engine damage.
Running the engine with persistent spark knock or pinging is considered misuse, and the Distributor’s Limited
Warranty does not cover parts damaged by misuse.
