RECOMMENDED OIL TYPE
Using the proper type and weight of oil in the
crankcase is extremely important. Check the
oil before each use and change the oil
regularly. Failure to use the correct oil, or
using dirty oil, can cause premature engine wear and
failure.
Use a high-quality SAE 30 weight oil of API (American
Petroleum Institute) service class SF, SG, SH.

Your unit is supplied with one 3.4 fluid oz. (100 ml.)
bottle of SAE 30 SF, SG, SH oil (Fig. 17).
NOTE: Save the bottle to measure the correct amount
for future oil changes. See Changing the Oil
Pg. 20.
