How To Change The Oil
Change oil after first 5 to 8 hours of use, then
every 50 hours. Change oil every 25 hours when
operating the engine under heavy load or in high
temperatures.
1 Make sure the engine is level.
2 Disconnect the spark plug wire and keep it away
from the spark plug.
3 With engine off but still warm, remove the oil drain
plug (A) as shown in Figure 18. Drain the oil into
an appropriate receptacle.
8 To add oil, pour the oil slowly into the engine oil fill.
The engine holds approximately 20 ounces (0.6
liter) of oil. For the type of oil to use, see "Oil
Recommendation" in the Operation Section.
9 Before checking the oil level, wait 2 minutes for the
oil to drain out of the oil fill. Then, install the
dipstick and check the oil level. Make sure the oil
is at the FULL mark shown on the dipstick (see
Figure 19). Do not overfill.
10 Connect the spark plug wire to the spark plug.
