Engine - Yamaha EF2000iS Owner's Manual

Engine

Perform the following steps to protect the cylinder, pis-
ton ring, etc. from corrosion.
1. Remove the spark plug, pour about one table-
spoon of SAE 10W-30 or 20W-40 motor oil into the
spark plug hole and reinstall the spark plug. Recoil
start the engine by turning over several times (with
ignition off) to coat the cylinder walls with oil.
2. Pull the recoil starter until you feel compression.
Then stop pulling. (This prevents the cylinder and
valves from rusting).
3. Clean exterior of the generator and apply a rust
inhibitor.
4. Store the generator in a dry, well-ventilated place,
with the cover placed over it.
5. The generator must remain in a vertical position
when stored, carried or operated.
