Acceptable Oil Level – On the flat side of the dipstick, oil
is visible up to the first notch.

engine oil incrementally and recheck until the level is at
the top notch on the dipstick. DO NOT overfill. If over the
top notch on the dipstick, drain the oil to reduce the oil
level to the full mark.

the oil fill cap.

5. Twist the cap clockwise to close. Secure the hose in the
hose clip.
6. Place the oil pan under the oil filter. Remove the oil filter
by rotating it counterclockwise. Allow the oil to drain
completely. Clean the area where the oil filter contacts
the engine.
7. Apply clean oil to the rubber seal on the new oil filter.
Install by hand, turning clockwise until the seal contacts
the engine then turn another 3/4 turn. DO NOT over
tighten.
8. Fill with the recommended oil. Stop frequently to check
the oil level. Do not overfill. If the engine is overfilled,
the excess oil may get transferred to the air cleaner
housing and air filter. An indication of overfilling is white
or blue smoke coming from the muffler when the engine
is running.
Maximum oil capacity: 1.7 Quart (1.6 Liter)
