tank completely . It may be necessary to lower the fuel
level depending on operating conditions . After refueling,
tighten the fuel filler cap securely .
Keep gasoline away from appliance pilot lights, barbecues,
electric appliances, power tools, and anything else that may
generate a spark . Spilled fuel is a fire hazard and causes
environmental damage . Wipe up spills immediately .
Engine Oil
Oil is a major factor affecting performance and service life .
Use a 4-stroke automotive detergent oil . Use a funnel with a
long spout to add oil .
Recommended Oil

requirements for API service category 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) .
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 .

Check the engine oil level with the engine stopped and in a
level position .
1 . Remove the oil filler cap/dipstick and wipe it clean .
2 . Insert the oil filler cap/dipstick into the oil filler neck as
shown, but do not screw it in, then remove it to check the
oil level
3 . If the oil level is near or below the lower limit mark

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 .
Oil Change
Drain the used oil when the engine is warm . Warm oil drains
quickly and completely . Use a funnel with a long spout to
add oil .
1 . Place a suitable container below the engine to catch the
used oil, then remove the oil filler cap/dipstick, oil drain
plug and washer .
2 . Allow the used oil to drain completely, then reinstall the
oil drain plug and new washer, and tighten the oil drain
plug securely .
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 with the
recommended oil (see
“Recommended Oil” on page 12
)
