REFUELING
This engine is certified to operate on unleaded gasoline with a pump
octane rating of 86 or higher (research octain rating of 91 or higher).
We recommend refueling after each use to minimize the air present in
the fuel tank.
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. In addition, ethanol is hygroscopic,
which means it attracts and retains water in 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 by warranty.
If your equipment will be used on an infrequent or intermittent basis
(more than 4 weeks between usage),
FUEL-RELATED PROBLEMS” on page 14
for additional information
regarding fuel deterioration.
Never use stale or contaminated gasoline or oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
Adding Fuel
See Figure 1,
1. Remove the fuel tank cap.
2. Add fuel to the bottom of the fuel level gauge [1] in the neck of the
fuel tank. Do not overfill. Wipe up spilled fuel before starting the
engine.
3. Install the fuel tank cap and tighten it until it clicks.
Move at least 10 feet (3 meters) away from the fueling source and
site before starting the engine.
NOTICE
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 your
Distributor’s Limited Warranty

ENGINE OIL
Oil is a major factor affecting performance and service life. Always
change the oil in accordance with the maintenance schedule
(
).
Recommended Oil
.
Use 4-stroke motor oil that meets or exceeds the requirements for API
service category SJ or later. Always check the API service label on
the oil container to be sure it includes the letters SJ or later.
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
See Figures 2 and 3 on
1. Check the oil with the engine stopped and level.
2. Remove the oil filler cap/dipstick [1] and wipe it clean.
3. Insert the oil filler cap/dipstick into the oil filler neck as shown, but
do not screw it in, and then remove it to check the oil level.
4. If the oil level is near or below the lower limit mark [2] on the
dipstick, fill with the recommended oil to the upper limit mark [3].
Do not overfill.
5. Reinstall the oil filler cap/dipstick [1].
Oil Change
.
Drain the engine oil when the engine is warm. Warm oil drains quickly
and completely. Place a suitable container next to the engine to catch
the used oil.
1. Without oil drain bolt.
Turn the fuel valve to the OFF position to reduce the possibility of
fuel leakage.
Remove the oil filler cap/dipstick [1] and drain the oil into the
container by tipping the engine toward the oil filler neck [4].
2. WIth oil drain bolt.
Remove the drain bolt [5] and allow the oil to drain into the
container. Reinstall the drain bolt after draining.
Please dispose of used motor oil in a manner that is compatible
with the environment. We suggest you take used oil in a sealed
container to your local recycling center or service station for
reclamation. Do not throw it in the trash, pour it on the ground, or
pour it down a drain.
3. With the engine in a level position, fill to the upper limit mark [3] on
the dipstick with the recommended oil.
NOTICE
Running the engine with a low oil level can cause engine damage.
4. Reinstall the oil filler cap/dipstick [1] securely.
WARNING
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.
