3. Remove the dip stick (C) and clean it with a paper
towel.
4. Insert the dip stick back into the engine. Thread the
cap back into the tube (D).

*CAUTION:Air cooled engines run hotter thanautomotive engines.
The useof non-synthetic multi-viscosity oils (5W-30, 10W-30,etc.)
intemperatures above 400F(4°C)will resultin higher than normal
oil consumption. When using a multi-viscosity oil, check oil level
morefrequently.
**CAUTION: SAE30 oil, if usedbelow 400F(4°C),will result in hard
starting andpossible engine boredamagedue to inadequate
lubrication.
