REFUELING

Recommended Fuel
Unleaded gasoline
U.S. Pump octane rating 86 or higher
Except U.S. Research octane rating 91 or higher
Pump octane rating 86 or higher
This engine is certified to operate on unleaded gasoline with a
pump octane rating of 86 or higher (a research octane rating of 91
or higher).
Refuel in a well-ventilated area with the engine stopped. If the
engine has been running, allow it to cool first. Never refuel the
engine inside a building where gasoline fumes may reach flames
or sparks.
You may use regular unleaded gasoline containing no more than
10% Ethanol (E10) or 5% Methanol by volume. In addition,
Methanol must contain cosolvents and corrosion inhibitors. Use of
fuels with content of Ethanol or Methanol greater than shown
above may cause starting and/or performance problems. It may
also damage metal, rubber, and plastic parts of the fuel system.
Engine damage or performance problems that result from using a
fuel with percentages of Ethanol or Methanol greater than shown
above are not covered under warranty.
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when refueling.
Stop engine and keep heat, sparks, and flame away.
Refuel only outdoors.
Wipe up spills immediately.
Fuel can damage paint and some types of plastic. Be careful not to
spill fuel when filling your fuel tank. Damage caused by spilled
fuel is not covered under the Distributor's Limited Warranty.
1. With the engine stopped and on a level surface, remove the fuel
tank cap and check the fuel level. Refill the tank if the fuel level is
low.
Refer to the instructions provided with the equipment powered
by this engine for refuelling.
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. It may be necessary to lower the fuel level depending
on operating conditions. After refueling, tighten the fuel tank cap
securely.
Keep gasoline away from appliance pilot lights, barbecues,
electric appliances, power tools, etc.
Spilled fuel is not only a fire hazard, it causes environmental
damage. Wipe up spills immediately.

ENGINE OIL

Oil is a major factor affecting performance and service life. Use
4-stroke automotive detergent oil.

Recommended Oil

Use 4-stroke motor oil that meets or exceeds the requirements for
API service classification SJ or later (or equivalent). Always check
the API service label on the oil container to be sure it includes the
letters SJ or later (or equivalent).
AMBIENT TEMPERATURE
SAE 10W-30 is recommended for general use. Other viscosities
shown in the chart may be used when the average temperature in
your area is within the indicated range.

Oil Level Check

Check the engine oil level with the engine stopped and in a level
position.
1. GX670 ONLY: Start the engine and let it idle for 1 or 2 minutes.
Stop the engine and wait for 2 or 3 minutes.
2. Remove the dipstick and wipe it clean.
3. Fully insert the dipstick, then remove it to check the oil level.
4. If the oil level is low, remove the oil filler cap, and fill to the
upper limit mark on the dipstick with the recommended oil.
5. Reinstall the dipstick and filler cap.
FILLER CAP
DIPSTICK
Running the engine with a low oil level can cause engine damage.
This type of damage is not covered by the Distributor's Limited
Warranty.
The Oil Alert system (applicable types) will automatically stop the
engine before the oil level falls below the safe limit. However, to
avoid the inconvenience of an unexpected shutdown, always
check the engine oil level before startup.
