OUT OF SERVICE PROTECTION
If you cannot exercise the generator every seven
days and it is to be out of service longer than 30 days,
prepare the generator for storage as follows:
• Start the engine and let it warm up.
• While the engine is stili warm from running, drain the oil
completely. Refill crankcase with recommended oil. See
“Specifications."
• Attach a tag to the engine indicating the viscosity and
classification of the oil in the crankcase.
• Remove spark plug and add about 1/2 ounce (15ml) of
clean, fresh engine oil into spark plug threaded opening.
Crank engine several times to distribute oil, then install
and tighten spark plug.
• Remove the battery and store in a cool, dry room on a
wooden board. Never store the battery on any concrete
or dirt floor.
• Clean and wipe the entire generator.
