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
Use 4-stroke motor oil that meets or exceeds the
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 .
Oil Level Check
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

on the dipstick, fill with the recommended oil (see
“Recommended Oil” on page 12 ) to the upper limit mark
on the bottom edge of the oil fill hole . Do not overfill .

plug securely .

service station for reclamation . Do not throw it in the trash,
pour it on the ground, or pour it down a drain .
