Servicing Your Engine

REFUELING

With the engine stopped and cool, remove the fuel tank cap and check the fuel level. Refill the tank if the fuel level is low. Leave
enough area in the tank to allow for fuel expansion caused by heat. This will help prevent fuel from being forced from the tank onto a
hot surface. NEVER FILL TANK ABOVE MARKED RECOMMENDATIONS ON FUEL STRAINER.
WARNING
Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel.
• Stop the engine and keep heat, sparks and flame away.
• Only handle fuel outdoors.
• Wipe up spills immediately.
• Allow engine to cool before refueling.
Refuel in a well-ventilated area with the engine OFF and cool. Avoid spilling fuel. Do NOT fill above the fuel strainer marking. Fuel cap
should make a "clicking" sound when properly tightened. After refueling, tighten the fuel tank cap securely. Refuel the engine in a
properly ventilated location and away from where fuel fumes may reach flames or sparks. Keep fuel away from appliance pilot lights,
barbecues, electric appliances, power tools, and other electric appliances.
Spilled fuel is a fire hazard and it causes environmental damage. Wipe up spills immediately. Do not use cell phones or other electronic
devices while refueling. Prevent static electricity when refueling. Fuel can damage paint and plastic. Do not spill fuel when filling your
fuel tank. Damage caused by spilled fuel is not covered under warranty.

FUEL RECOMMENDATIONS

Use unleaded gasoline with a pump octane rating of 86 or higher. These engines operate best on unleaded gasoline.

ENGINE OIL LEVEL CHECK

Check the engine oil level with the engine stopped and with the engine in a level position.
1. Remove either side mounted filler cap dipstick or high oil fill dipstick (if equipped) and wipe it clean.
2. Insert the dipstick into the filler neck and turn clockwise until fully seated. Then remove the dipstick by turning it counter-clockwise.
Check the oil level shown on the dipstick.
3. Securely screw in the filler cap/dipstick. Running the engine with a low oil level can cause engine damage. Always check the
engine oil before start up.
