days, prepare the generator for storage as follows:
1. Start the engine and let it warm up.

line and allow the unit to shut down.
3. While the engine is still warm from running,
drain the oil completely. Refill the crankcase
with SAE lOW-30 oil having API classification
"For Service SF.”
4. Attach a tag to the engine indicating the viscos­
ity and classification of the oil in the crankcase.
